As a cybersecurity engineer, I cannot hype up NIST enough. They maintain this security database that contains all known software vulnerabilities in existence. Every major company, government and military is using this database to check for vulnerabilities in their infrastructure. Thank you NIST.
Dude, while thats all well and good, given your cybersecurity background I thought you would be cognisant of the fact that NIST is a huge risk in cybersecurity because its very likely that atleast some of the approved algorithms, are ones the US government knows how to crack. This is in particular with the ECC algorithm curves we are starting to adopt.
As someone in the analytical chemistry field, these standards are vital. It is how analytical labs are able to charge such a price for what seems to be them just analysing a sample.
I am disgusted after watching this -- The only way a place like that get funding from the governent is that its not public knowledge of their bloated out of control budget/ spending. This place needs real oversight and would probably be shut down if omre stories like this aired. Nothing in that place or in the name of science, justifies the price tag of those materials or having what I imagine is equally overpriced staffers.
I love how passionate that guy is about his job. You can tell he loves so much about what he does, and he is so excited about it and it makes me really happy to see.
The existence of "Powdered Domestic Sludge" makes me immediately think of someone using it for a prank and not realizing they're commiting bioterrorism.
I work for a company that produces every type of analytical measurement instrument you could ever think of. We use NIST reference materials every day to qualify our instruments. We call them SARMs though, standard analytical reference materials. We use NIST steel spheres to calibrate our density measurement machines. They produce a great product, and are vital to industries like mine. Keep up the good work guys!
NIST is one of, if not the, most under appreciated of all US government agencies. I was lucky to be able to tour their metrology lab in Gathersburg, MD in 2007. It was just mind blowing.
Just makes me think that, in general, there's so many people with really deep knowledge and skills that are working away constantly to keep our world safe and operational. It's very useful to remember how we're all so dependent on people like this.
@@TimmmTim Yeah, it seriously depresses me, the amount of people, especially older people who simply can’t fathom trusting others. I suppose it can be hard. Though as Roger said, it is comforting knowing that there are people who are out there who are extremely skilled, and do what they do for the common good.
I'm a pharmacist and always ensured my students knew that the temperature monitoring devices (basically a thermometer) for the refrigerator/freezer that holds medications must have a certificate of calibration tracing its accuracy back to NIST, as well as ensuring they knew those devices do in fact "expire" and should be re-calibrated or, more practically, replaced. Great video to get to see the rest of NIST's world!
Even weights need to be checked if you're working within fine enough tolerances. It gets even wierder with timing stuff, as thats influenced by the speed its moving. A clock has to be perfectly accurate in a satellite for a gps to work, but they also lose 7 millionths of a second per day or something just because its moving faster.
@@bibsp3556 Its more the fact its further out of earths gravitational field than the speed. The %difference of gravity is more significant than the %difference of the speed of light. But yes, they do lose time and that causes errors in the positioning of the satellite and slowly over time will cause the satellite to give wrong coordinates to a gps if not recalibrated.
@@randomname4726 eh, simulation theory to me is more a philosophical question. I've not really seen anything beyond hypothesising that the planc length and speed of light might be some.sort of processor limit, but it's not convinced me really. As the guy said above correctly said though, it's more the gravity, but yeah it's fascinating. Crazy out there
I used to work as a chemist in a materials testing lab, and we used NIST metallic standards constantly. Our machine shop even machined a lot of those charpy standards for NIST!
I didn't quite understand the Charpy test: What use is it? Don't they just measure the force required to break that Charpy? How does that measure anything from the manufactured steel? Or is the Charpy made from the steelmill's steel?
@@RevCodein simple word, that Charpy sample is so homogeneous and properly made (according to ISO 148 part-1) that all the Charpy samples prepared in a lot are having almost same results. So if u test one sample and have the result, say 40 joules, and the actual value of the Charpy sample (which is known to these NIST guys, coz they tested it before) is 39 joules, then by statistical analysis it can be found out how perfect your machine is calculating the impact value. Basically comparing apple with another known apple 😂
@@thugpug4392 Oh I see, so they calculate the baseline from the standardized one and then know their steel's strength. If I wasn't so dumb I guess I could have guessed that by the name "reference material" alone - thank you for enlightening me, that was not my brightest moment :)
I work in an analytical lab here in Brazil and I use a lot of this peanut butter reference material as a quality control for mycotoxins, fatty acids and metal ions in food. It smells so good though! And thanks a lot for these people that work at NIST and make this reference materials. You guys rock!
Except for the 9/11 NIST report, which made such dramatic changes to the structural properties of concrete and steel that, were they true, large swaths of the frozen north would be unable to build structures taller than 3 stories. I wonder if this is the guy that approved the expansion rates of steel and concrete under heat for the 9/11 NIST report?
@@unifiedtheoryoflife9922 there are no high rises in the “frozen north” that you speak of that even closely reaches the height that the trade centres did lmfao
@@Tmktrsf The number is 3 floors - and the north is anything that freezes in the winter. NIST 9/11 report changed the known expansion rate of steel and concrete by so much that you could not buld a 4 story building in Chicago, because the 4th floor would need to be steel, and the steel and concrete apparantly separate under office fire heat, so imagine what 100 degrees the other direction (0F) does. It makes Chicago a one stop light town
@@unifiedtheoryoflife9922 reality: a building collapses due to a +500F delta you: hOW CAn BuilDInGs EvEn WiThSTanD a -100F DeLTa TheN? Genius. Besides, contraction vs expansion are different. Materials have different strength in tension vs compression. And when looking at a structure as a whole, crushing the structure vs tearing it apart is pretty different.
The director of NIST seems to me to be one of the most approachable and likeable civil servants of whom I've ever had any exposure. You're a cool dude, sir! Your general state of apparent happiness is enviable.
It's amazing how complex our world is and how we depend on systems that 99.9999% of us have no idea exist and can't possible be thankful for. Thanks for giving me this knowledge and sharing such important research with the world Derek. :)
Yeah, that is pretty interesting. Even something you are an expert in is based on a totally different thing you might have not much idea about. Eg- a software developer might not have great knowledge on how computers are working behind the scenes, meanwhile a computer engineer will. These computer engineers might not fully understand how the materials they use (semiconductors) work but the material scientist will. This is just one example. Even for something less ‘hi tech’ there is so much that is done by others we don’t understand fully how they work, we just know what it does and how to use it. This is good so different people can become experts in different areas via specialisation.
@@anntakamaki1960 reminds me of a stand up comedy bit about how dumb the avg person is. "We're not smart. We just use stuff made by smart people". The big punchline was "if I sent you into the woods with a hatchet and a lighter, how many years till you could send me an email?"
Yep - my father is a soil chemist that runs quality control programs for soil testing labs. There's way more of these labs than you think, because they're used by farmers to determine what kind of fertilizer to put on their fields (among many other things). What's fascinating is that because the QC program is so large, the excess soil is highly desirable by labs to use as reference and calibration material for equipment. And that's how he ended up selling buckets of dirt internationally.
Working in the lab of a sewage treatment plant, was interesting for a while, but then became insanely boring, but one neat thing was the fact that the more accurate our scales were, and also our ability to dispense the necessary items for testing, the smaller the test sample could be, and therefore the less of those necessary items would be used as well. Our scale was so accurate that we could weight our fingerprints. We would have elementary school kids tour the plant from time to time, and we would pick one to pickup a beaker while we turned our back, then we could correctly tell them how many fingers they used to pick it up with. We did have to instruct them to use the pads of their fingers not the tips to make it fair, but as long as they played fair, we had a 100% correct “guess”, and the kids absolutely loved it. We also typically picked a kid that was somewhat socially awkward, which made them the big shot hoping to help them socially.
My dad was a steelworker for about 40 years. They sent him to get qualified as a metallurgist before taking up his head foreman role. It's a fascinating subject! As a one-time geology student, I found the identification of the ores to be really interesting. Maybe his own real interest in the subject is where my son got his inbuilt fascination for chemistry (he's now a PhD medical biochemist! He's way, _way_ smarter than me lol!).
Handling a 50 micron spherical ruby single crystal from NIST to calibrate X-ray diffraction equipment has been one of the scariest experiences I ever had as a researcher... I had nightmares about dropping it on the floor and losing it
I don’t even get how you handle something that small, I assume you have special tools to hold it but what’s stopping you from accidentally inhaling it lol
@@Ze_Moose Honestly it's not even remotely close to goofing around with a ball on a field. If you're determined to stick with the football frame of reference, it would be like shooting a football through a cannon a few miles away, detonating a flashbang grenade in your face, and then trying to find the football while in a hurricane.
Fun fact: the Calories on the nutrition label is calculated by setting the food on fire! The Cal is a measure of energy released heating 1 g of water, the sample is placed in a sphere surrounded by water then ignited. The temperature difference of the surrounding water determines how much energy the food contains, as the stomach works just like a combustion engine or.... something like that
Exactly right! Except the term you're thinking of is "joule". 1 joule is equal to 0.24 calories. A joule is essentially the metric version of energy measurement and came around from (as you said) water! So, it takes 1 joule of energy, to heat 1 cubic centimetre of water, that weighss 1 gram, up by 1°c.
@@flynnjacob9 1 calorie is defined as the amount of heat required to heat up 1 g of water by 1 °C. 4.184 joules is equal to one calorie because the heat capacity of water (under atmospheric conditions) is 4.184 J/g °C. A joule is defined as the amount of energy required to move a 1 kg object for 1 meter at an acceleration of 1 m/s²
NIST also played a pivotal role in standardizing internet communication protocols. Without them, the Internet would be a much more chaotic and much slower
I interned at NIST in 2018 and saw the standard jar of peanut butter among lots of other things. It’s really cool to see the organization being covered here since they’re so important to so many businesses!
@@KJ4EZJ Unfortunately not. Like the guy said in the video, none of the standards are for human consumption, but I was and still am very curious about how it would taste
As a scientist, I really appreciate this. These guys are the ubernerds working behind the scenes to make sure us ordinary nerds can have the tools to do our jobs.
So how does this relate to what you do? There's a dozen kinds of peanut butter on the shelf in Walmart, what's the point off having some standard in a government warehouse somewhere?
@@Amaling Of course I did and that's not what he said. What he said is that they get some company - probably Jiff or Skippy - to make some kind of peanut butter and then this place says "This is peanut butter" and then that's what peanut butter is. But, as I said, there are at least a dozen different kinds of peanut butter on the shelf of the market, and many of them are different than the others. So what's the standard? Not having poison in it (or, conversely and more likely, how much poison will be allowed in it)? This sounds much more like the alliance between big corporations and the government.
@@phaedrussmith1949the reference material isn't supposed to be _the_ definitive peanut butter, it's to calibrate equipment so they can accurately measure levels of aflatoxins in their peanut butter
@@Osama-Bon-Jovi-01 So how do they know what they are calibrating against? Doesn't something have to have measured the aflatoxins first to know what the level of aflatoxins in the sample should test as? One can't calibrate equipment unless it is done against a known quantity.
This is probably the closest real life equivalent we can find to Plato's world of beings. A world of fundamental forms. And every object in reality is just a slight variation of these base forms.
I learned two things today. 1. These people's work is definitely underrated. Now I understand how some foods and products can exist for years and taste the same. Consistency is key and these people are definitely helping with that. 2. I'm never eating peanut butter anymore. 😅 Never again.
Everything you buy to eat is allowed to have a tiny, yet measurable, proportion of various disgusting contaminants such as cockroach heads (and other insect parts), rat poop, rat hairs, mold, mites... even maggots (ugh), and "other foreign matter".
As someone who worked at NIST for a while doing metrology and spectroscopy, I can tell you. That place is freaking awesome. The impact it has on the world is really quite incredible.
In an ideal future, they'd be shielded from budget cuts. But republicans are likely to retake and cut funding to them without any care for the appreciation of the sciences.
@@TooRiskyHD standards for measurements are critical. When the industrial revolution kicked off standardization became critical between industries. Gauge blocks were born as a means for checking measurements against one another quickly. I dont know if that was the first "standard" but it is necessary for there to be standards out there otherwise we would be doing a lot of guessing. That rotor you bought to replace your breaks might be too big or too small, the holes maybe got drilled incorrectly. Hope you understand the necessity for standards based on those couple examples.
@@tokin420nchokin yeh it makes sense to have matrix of something infact it’s smart I just never understood the poop part but you’ve went into detail about and it actually explains a lot I appreciate that thank you!
One of those things we take for granted...... but if you stop and think about how big, wide and "standardized" the world is, it's amazing. It makes it possible to eat some manufactured food and then wait 10 years, travel to another part of the world and eat the same food and have the exact same experience. I remember a local craft brewer saying he had a lot of respect for Budweiser for making millions of gallons of beer, over the course of decades and having it always be consistent and predictable.
I made a snarky comment about Budweiser beer to a well skilled craft brewmaster during a tour a few years ago. He immediatly informed me that Budweiser is actually a fantastically brewed beer for this exact reason. Humbling moment.
@@9ZERO6 Budweiser is fantastically brewed piss water if anything. Utter trash. The fact that they can reproduce garbage to such an exact standard doesn’t impress me. It caters to a brand loyalty crowd and little more.
This system ends up making everything they control more expensive for the consumer, and gives the consumer less choice. Among many other glaring issues. We can have transparency and certificates etc without total government control. Functional force is still force.
@@adamscrivener9574 I think you may be confusing the NIST with a regulatory body. NIST is a science laboratory setup by Congress to bring US standards up to world standard at the time. Trusted standards allow for improved safety, quality, and a plethora of other things. How the standards are to be applied and who enforces them is another ball of wax.
@@adamscrivener9574 I don't think you understand what NIST is. Without them, businesses would have to spend more money when trying to calibrate their equipment. Also, just from a broader perspective outside of what NIST does, regulation is necessary. We tried giving businesses free rein during the early 20th century and a bunch of kids lost arms in factory equipment. Businesses have no concern other than money they will hurt or exploit people for profit if left to their own devices.
@@adamscrivener9574 You clearly fall into the weird "GOVERNMENT BAD, NO EXCEPTIONS" camp. Free market capitalism is a race to the bottom. Capitalism needs standards and regulation. These standards save a ton of money and save a lot of lives. I'm not sure how you came to the conclusion that it makes things more expensive or gives less choice. That makes zero sense. Even with regulations and standards, companies are constantly caught cutting corners which often times result in a loss of life. NIST is a service that is invaluable to the global economy.
One of my favorite things about NIST is that the roads of their main campus are aligned to be parallel with lines of latitude and longitude. It's particularly noticeable on maps, as it doesn't mesh with the surrounding roads.
Looking at map and seeing NIST Sound Building, which I guess deals in standard sounds. Satellite view shows intersection of Sound Road and West Drive is torn up, so does that mean NIST offers a Standard Traffic Obstruction? Hmm, there is a NIST Child Care Center, do they have Standard Children?
Analytical chemist here. From academic research to drug development to drug safety testing, every position I've ever worked makes heavy use of NIST standards (though usually all with their own internal acronyms). These are absolutely vital for almost any calibration or measurement which requires high degrees of certainty.
I’m an analytical chemist, and anyone who works in any lab or in most manufacturing operations definitely knows and appreciates the vital importance of reference standards to calibrate our instruments and ‘test our tests.’ Now NIST isn’t the only game in town that provides SRMs, but you might consider them the ‘standard of standards.’
I deal with having to juggle multiple different steel standards, and let me tell you it's definitely a *_VERY_* detail-oriented job with a lot of spreadsheets. It's astounding how the tiniest changes in composition and forging methods can lead to *_vastly_* different physical characteristics. Buy coils from two different heat lots of steel from the same mill for the same grade, and those two coils can pass and fail two completely independent lists of other standards. It's the whole reason why "grades" exist: to pigeon-hole a gradient of differences. Also yes: Charpy Testing is common.........and loud; though not as loud as testing tensile strength, lol. _(testing the tensile strength you literally just take a bowtie-shape piece of the material and stretch it until it breaks - which is usually accompanied by sounds as loud or louder than a gunshot when it's steel - or at least it's sudden enough that it feels like it's that loud, lol)_
Sounds like my old job. As someone who understands this video do some of the comments scare you? As for loud, in addition to dogbones we also tested 4.500 OD pipe. It was made from HSLA steel with a yield of 83,000 psi. That was loud and fun
I have been worried for so long about how there wasn't a real chemical definition of what the kinds of food we eat are because I didn't know NIST existed, but now I can eat in peace knowing there is a standard jar of peanut butter out there that the peanut butter I'm eating should at least have been made in reference to.
I am not a science nerd or in any profession that depends on this kind of information and I was fascinated and amazed by this information. Thanks for making this available to your average little old lady. We are never too old to learn.
@@madhououinkyoma - well if they do not - as it happens - I have made arrangements to donate my entire body to science when I die - so - they can have their bit for the good of the world - if it is needed. I do hope they do not come to think of it - because that would mean there is a human component to any number of products - like hot dogs.
This is so interesting! I worked at an environmental testing lab and we did get standards from NIST but it was for our yearly test to maintain our certifications. Always super stressful to do those tests and hope you get the right answer because we don't have the certification he showed early on in the video. It's so neat to have a face and fuller understanding of a government body that put fear and terror in my heart lol.
There’s a great story you’re (usually) told during NIST orientation for new employees about the Great Baltimore fire of 1904. Lots of FDs from surrounding municipalities and states came to try to help, but at the time, there was no industrial standard for hoses/couplings, so it turned into quite a mess, and more injuries and damage arguably resulted. Those items are now standardized across the country. The HR folks are better storytellers, but still demonstrates the importance of the work of standardization
They should tell the story about how people quit nist and joined architects and engineers for 9/II truth because of the fake garbage they made them produce.
Met a guy on a game I was playing the other day who was an airbag engineer. One of the most down to earth people I’ve ever had the joy of interacting with, although our interaction was brief. It’s always the most important things you forget has to be thought of, designed, created, tested, redesigned again and again until it was just okay enough.
@@samthunders3611 For scientists perfect does not exist. That's what standards are for - _"Does this system or object meet the standards to do the job?"_ Stuff like NIST is why you can buy a bag of concrete, follow the directions, and actually get the same results as the factory did.

There are also groups trying NOT to standardize things. The most troubling being the vitamin industry. Vitamins in the USA and Canada have no standards so vitamins can have whatever in them. Some even don't contain the vitamin on the label at all. It just goes to show why standards are important.
This video confirms what I've recently learned that NIST touches every aspect of our lives, from the accuracy of your metric ruler to the accuracy of the compounds that go into a jar of peanut butter. I first learned about NIST in 1977 (known back then as the National Bureau of Standards) when I was about 7 years old, and at the time, I figured all they did all day was make sure clocks ran accurate right down to the nanosecond.
There is a brand that sells named literally as the article itself. Like Water would be named "Water". I think you would like this company and its products lol. It's called No Name and is located in Canada.
This place reminds me the "Developers Room" that's (secretly) present in most of Bethesda games. It's a room that has every material used in the game. NIST is the IRL version of this xD
I work in a geochemical analysis lab, and standards really are a critical part of our work, letting us find, diagnose and correct any errors and deviations and confirm when data is on point. Thanks, NIST, for your tireless diligent work!
Great work, Derek, as always. True story: Back in the early 70s I worked in a radio maintenance shop at McConnell AFB, Ks and some of the radios we maintained were in the HF band (3 - 30 MHz). The NIST runs a radio station call sign WWV which operates on 2.5, 5, 10, 15, and 20 MHz and continuously broadcasts the current time. We used to tune the radios to WWV to confirm that they were tuning properly. We also would set our watches to WWV so we always had very accurate time on our watches. One evening the wife and I were in a mall window shopping (as a junior enlisted we didn't have the money to actually BUY anything) when some guy asked me for the time. I told him the time to the second. He said "That isn't right!" To which I replied, "Yes it is. I set my watch by WWV just this morning." "What's WWV?", he asked. " It's the national time standard. You know? The same folks who establish the standards for everything in the U.S." I told him. He then asked, "What makes THAT right?" Honestly, I didn't have a comeback. How would you answer someone who questions the National Institute of Standards and Technology? (I'm really hoping you answer my question. I was at a loss.)
Lol. Nothing, in a sense. It's just a reliable institution that everyone can go to to help them synchronize their devices that need to be synchronized. You could make your own competing timekeeping service, but good luck making it as reliable, so nobody would bother with it if they really *needed* it.
It’s funny, because there really isn’t anything that makes it right. It’s like how the standard weight of a gram is just a little hunk of metal in a lab and everyone agrees “yeah that’s a gram” because who else is defining a gram? Or how most world currencies only have value due to the people agreeing that they do. It’s a little arbitrary, but it negates arbitration. Which is weird lmao
In some cases a standard is just an authority meaning we simply have to agree to not disagree. But in fact most standards have agreeable metrics. Ones that would cost more to derive in our own sample than it would to buy a NIST sample and test that. These standards also should be designed so they give you some useful information. Note how NIST only makes these samples at the request of companies.
I’m in my undergrad, and I worked on a project that was examining mercury deposition. One of the things that was done for the project was measuring certain samples we collected for mercury. Reference standards were used for that, we used soil standards. It was very interesting to learn about how important these standards are.
This entire concept is amazing. Rather than speculating about the invisible laws of the universe or what lies far away in space, being able to understand the things we interact with on a day-to-day basis seems strangely way cooler to me.
@Nad Senoj - The things NIST is doing are quite obviously beneficial to humanity. I'm going to need some real convincing why looking at barely discernable images of galaxies 13 billion lightyears away really helps mankind. The things NIST is doing are important and helpful right here and right now.
@gridsleep Standards are perfect because they are standard (thus why SRMs are used as references to determine product integrity), and they are standard because we have deemed them to be adequate enough for a certain product. They are a PERFECT template to ensure the quality of a certain product. So I say that perfection is quite definable.
@@teslacoil5378 Absolutely right! And one can say that standard dust collected in an American standard city is only standard in the US. Global dust must be collected globally, but that probably wouldn't make much sense, except for aliens collecting dust to make "standard inhabited planet dust"
As someone who basically did the same thing for several years, just across the pond (Germany), I'm so glad this important field of research finally get some coverage. The federal institution I used to work for provides the reference alloys for Euro coins, alcohol in water (calibrate breathalyzer's), also a lot of food and environmental samples with toxins or heavy metals and much more. I worked in the food team and alongside homogenization, stability is one of the major concerns. Grinding it into a nice powder is great for homogenization, but simultaneously creates so much surface area for chemical reactions. And even though they are not used as a food, you don't wanna an Oil to become rancid and so on. So many products are stored in a freezer, but what to do if e.g. the cold chain is broken during transport? The devil is in the detail^^ And that's even before you come to the most difficult question: How to make sure NIST and all the other CRM providers are able to measure correctly themselves? :D
That's where intercomparisons come into play. Also a reason why it's important that every reference is implemented by several national labs. When you are alone with a reference (as is the case with some of what PTB is doing) it's very difficult to be confident that you have not messed something up ;)
These are some of the problems that we in the bio fisheries face. You have to take into account the influx and outflow of water and what that water holds. We take our shipping containers almost too seriously. Wipe out all life inside the bag, measure what the water does to the bag and vice versa. Then place the fish into the bag, measure and record. For everything, and I mean like a full 2 days worth of testing for a single fish. Meanwhile that 1 single fish has required about 150 hours of work just to maintain a stable environment. Then when you ask for $3500 for a fish that someone could throw a net out in the river and catch thousands in an hour... Cheezus.. Some people just don't care to realize the effort that was put forth and call just to complain about the price for a perfect lab fish. They don't want one, just call to criticize us for the price of a river minnow. They want a dozen for $10. Sorry, we are not that kind of business.
This video explained how so many things work. People would say they found trace amounts of a certain chemical in a city's water supply, and you'd think "How?" well this is very enlightening. Also always wondered how in shows like CSI they could tell if a bullet was fired from a specific firearm. This is what i subscribed for.
Also, in relation to your specific example about the water supply, a lot of places periodically take samples of their water and store it for later for purposes like that!
Have you seen the arguments that A&E911 has made against NIST and there statements about building 7? In my opinion NIST and our government still have alot of explaining to do about the demolition of the three towers that day. Your statement about scientists being most meticulous made me comment.. If you didn't catch it I think nist is dogwash
Even as an analytical chemist, where being meticulous about everything is essential to everything I do at work, I could never match the level of NIST scientists. The methods they use are absolutely top notch and I'm grateful for their work. I don't believe my lab buys NIST standards as we're not in the US, but I rely the NIST mass spectral libraries every single day.
NIST is probably the coolest agency people don’t know about. Not only do they do this, but they have hardcore experimental physicists building the most accurate atomic clocks in the world to standardize timekeeping.
@@lysanderhoppe765 you want 1 standard. Not 2, not 3 not 5. Just one where everyone has the same error margins so there's no confusion. And if it were a company, then they would increase the price. And a lot of products would cost more because of that bloated price in calibration. So... Why would you want a company? Without competition companies aren't better than goverment
@@miguelangelmartinezcasado8935 Exactly. Why don't we have colour fax machines? Well, we do, except every manufacturer made their own "standard" for it and insisted that anyone else who wanted to use the same "standard", pay for it. So Acme colour fax machines can only send colour faxes to other Acme colour fax machines. Compare this to Wi-Fi, based on the IEEE 802.11 family of standards: one standard that any company can develop a product to use and know that it will be able to interoperate with billions of other devices out there. Having one free to use standard lowers the cost of entry into a market, enabling competition and innovation.
I love Steve Choquette. He seems to genuinely love his job. Both how it generates a profit, but also how it benefits the world. He's also very much aware of how ridiculous the job appears at first glance. He's not defensive. He embraces the absurdity.

I am sure your video will create a lot of awareness about this critical work being done by scientist behind the scene.
@@alihuss.3545 sorry . Get a knee jerk reaction whenever i hear the word "scientist" . In fact ..if you want to lose me as an audience then call yourself an "expert" . We got millions of them .

But most of us have forgotten about that one and I suppose we should "move on" ....like this Covid vax snarfu.
One thing I like about Veritasium is that it teaches about subjects that you don't often hear about. I watch a lot of science videos on UA-cam, but this is the first time I have ever heard about this warehouse. What an interesting subject! Thank you.
I'm a medical lab tech, and I find NIST to be fascinating. We use standards (we call it QC) to make sure that our analyzers and methods are working properly and giving accurate results so that you get the care you need next time you're in a hospital. Our stuff's not cheap either.
This was genuinely so interesting. I didn't know this was a thing! I love how passionate that guy was about his work but how do people even know they want to do this kind of thing as a career?
I assume they just know that they like science, so they study chemistry in college and then grad school, and along the way as they get more into the different rabbitholes of chemistry they start to learn about this type of thing existing
For several years, I worked right across the street from NIST in Gaithersburg, but I never knew that they had a warehouse in there! I certainly am aware of what they're doing in general, but was completely oblivious of this. Neat!
I thought they were only weights and measurements but this deep dive into NIST is absolutely fascinating! I love the wide variety of extreme detail they get into.

I was so confused at first but it makes total sense. Reminds me of that video you made on that perfect spherical ball that's our reference standard for weight. I calibrate lasers at my job and we have to check customers laser trackers against our reference tracker and if the results are outside of 0.0003mm we have to re-tune them. It's pretty neat. (Edit: I had originally said 0.00003 microns but it's .0003mm or .3 microns)
@@caiocc12 I think I added an extra zero lol. But there are different specs for different companies & trackers since everyone uses the trackers differently so some allow for larger margins of error.

Work hard and you'll be set for life.
That ball is not used as a reference. They don't use artifacts to define weight, and that ball was a candidate for defining the kilogram, but they went with a procedural definition using a watt balance and defining physical constants
@@pyropulseIXXI I think that went over my head lol. I thought that ball was the standard for 1 kilogram but it wasn't based on it's weight and instead the amount of atoms or molecules that it was made of? Or something like that? That video was a while ago so I don't entirely remember
As a calibration tech I Love actually seeing some calibration type stuff being put into the mainstream! So much calibrations are done on everything that most don’t know about!
I'm so glad domestic sludge was only a small part of the video, important as it is. I had no idea how interesting standards could be! It's super cool to see every constituent ingredient in all these substances. It's like a library of everything.
The actual title and thumbnail of this video almost made me not watch it. Only did because it's Veritasium. If the title was something about standards or something I would click it immediately. I guess sometimes clickbait does not work the same for everyone and it can even have the opposite effect.

You have made such a fantastic and captivating video on a bizarre concept that actually ends up making a whole lot of sense. We are blissfully oblivious of the behind-the-scenes effects of standardization in our lives. That's so interesting!
The Charpy test is indeed an important standard test for steels. It measures the toughness, or resistance to brittle fracture, using a standard notched specimen. Materials prone to brittle fracture are to be avoided (or mitigated). Ductile fracture does not sound so good either, but if something is going to fail, ductile failure is safer and preferable as it requires exceeding design loads to achieve this. Brittle failure is of concern because it can occur at less than design load conditions. The typical units of measure are energy (absorbed) in Ft-Lbs for imperial unit system, Joules for SI units. Metals and most solid materials become more brittle as temperature is decreased. Higher values measure in this test are better than low values. Brittle high strength steel may yield single digit values, whereas low strength austentic stainless steel may yield 300+ Ft-Lbs, meaning it takes a lot more energy to break it in a notched impact specimen, even though it is not nearly as strong. Different metal alloys and heat treat conditions will have different temperatures at which they become brittle (Ductile to Brittle Transition Temperature, or DBTT). The temperature at which the test is performed is based on design standards and factors such as the end product's minimum design temperature, and the material's expected DBTT. If the material is produced correctly, it will meet or exceed certain impact energy values at a given temperature. If not, it may produce low values and indicate sub-standard material. The notch of the specimen, which is the designed point of failure is machined to precise dimensions for the purpose of consistency. I am a Metallurgical Engineer and thought I should delve into sharing my personal understanding of that part of the video.

Charpy is just one way to measure one variable in a steel. Many times in tool steel you don't really care too much about that value, and are looking for wear resistance, such as drawing forms.
@@scottrackley4457 Good point. Toughness is not a required or necessary property in some materials and some applications. It is in structural and pressure containing products, but typically not in tooling. In fact in tool steels, low toughness often times is very acceptable in order to get the high strength or wear resistance that is required. Hence tool steels when they fail, tend to fail in a brittle manner.
Oh my, I love this video so much. I have long been fascinated and humbled by the standardization efforts in the world. ISO, ANSI, and innumerable technical standards, all of which probably at some point in their development interact with the tangible products NIST produces to actually substantiate their standards. These are the mechanisms that make modern society function. They are foundational to the quality, reliability, and consistency of almost every single moment of our lives. It would be a dream to contribute to that.
Wasn’t that a standard lesson in elementary school? It’s called the food pyramid. Not trying to be mean just wondering if it was in your curriculum because i feel like that’s an important thing for schools to be teaching kids
I didn't think this video would be that interesting, but I found it facinating. We don't typically think about how things are measured, just that they are. We always have to compare things to a known quantity (or quality) to measure it properly. We have standard units of measure for weights, time, etc. Why not peanut butter? 🙂
Wow, I'm just learning about this today. I always assumed we must've had something like this but never knew for sure. This makes me feel so much safer!!! Thank you so much NIST people!!!
I love that institutions like this exist. It's a large scale, collective enterprise, based on providing a practical service that can improve the quality, reliability and efficiency of nearly every kind of production. It's a thing that exists, not because it's serves one person or group's selfish interests, but because it has the potential to serve everyone's best interests. The fact that such institutions exist makes me a little bit less cynical about human nature and potential. Who knows? Maybe our species has a future after all.
This video is so important, especially these days with all the doubt around societies' systems. There ARE standards, and there ARE checks and balances in place.
Of course, it's called Quality Assurance and almost every company within every industry has it. The problem is the human element, there is no "standard" for good leadership or decision making and that is what causes doubt in very particular systems in society. As far as products are concerned though, the US is certainly above and beyond when it comes to quality and consistency, and it is thanks to organizations like NIST who play a vital role in standardized excellency.
I think these guys just beat the entire German system in being obsessed with norms Also, this kinda feels like they're the old school "scientist", dealing with absolutely every industry and scientific concept, gaining general knowledge about everything. Generalists instead of specialists
my entire family does water treatment and this provided such a massive insight as to why they're always spending thousands on books that contain these standards. i love this video. edit: i do realize the books they're buying are actually standard procedures (specifically analytical testing), but it's the same idea
The ASTM standards are all put together by volunteer committees and most the time the members actually have to pay ASTM to go to the seminars at which the committee meetings are held, they only costs involved for ASTM are the publishing costs. They're overpriced because ASTM has a monopoly and can get away with charging those ridiculous prices, not because those prices accurately reflect their costs. I've sat on many ASTM committees over the years, it's all a racket. NIST isn't quite so bad, they're inefficient like all government agencies, but at least their prices reflect their costs.
@@JakeInvest So he can accuratelly measure response. This is also where they order canned laughter from. Only thanks to them they can add just the right dose on laugh track or be certain they read test audiences' reaction accurately. (Test audiences of course consist of standard moviegoers. Those are stored frozen coz being exposed to outside influences they change their taste incredibly quickly.)

Nothing excites me more than the work NIST does, thank you for bringing attention and focus to their work!

Even weights need to be checked if you're working within fine enough tolerances. It gets even wierder with timing stuff, as thats influenced by the speed its moving.

I used to work as a chemist in a materials testing lab, and we used NIST metallic standards constantly. Our machine shop even machined a lot of those charpy standards for NIST!
I didn't quite understand the Charpy test: What use is it? Don't they just measure the force required to break that Charpy? How does that measure anything from the manufactured steel? Or is the Charpy made from the steelmill's steel?
@@RevCode you have some made from your steel and their steel has all the information known so it lets you test your machine .
@@RevCode It's made from BOTH. You run the test twice as to test your own test. That's what the word calibration means.
@@RevCodein simple word, that Charpy sample is so homogeneous and properly made (according to ISO 148 part-1) that all the Charpy samples prepared in a lot are having almost same results. So if u test one sample and have the result, say 40 joules, and the actual value of the Charpy sample (which is known to these NIST guys, coz they tested it before) is 39 joules, then by statistical analysis it can be found out how perfect your machine is calculating the impact value.

I work in a polymer manufacturing laboratory and I cannot stress the importance of standards enough! Such an interesting clip!
Working in the lab of a sewage treatment plant, was interesting for a while, but then became insanely boring, but one neat thing was the fact that the more accurate our scales were, and also our ability to dispense the necessary items for testing, the smaller the test sample could be, and therefore the less of those necessary items would be used as well. Our scale was so accurate that we could weight our fingerprints. We would have elementary school kids tour the plant from time to time, and we would pick one to pickup a beaker while we turned our back, then we could correctly tell them how many fingers they used to pick it up with. We did have to instruct them to use the pads of their fingers not the tips to make it fair, but as long as they played fair, we had a 100% correct “guess”, and the kids absolutely loved it.

@@TooRiskyHD standards for measurements are critical. When the industrial revolution kicked off standardization became critical between industries. Gauge blocks were born as a means for checking measurements against one another quickly. I dont know if that was the first "standard" but it is necessary for there to be standards out there otherwise we would be doing a lot of guessing. That rotor you bought to replace your breaks might be too big or too small, the holes maybe got drilled incorrectly. Hope you understand the necessity for standards based on those couple examples.

One of those things we take for granted...... but if you stop and think about how big, wide and "standardized" the world is, it's amazing. It makes it possible to eat some manufactured food and then wait 10 years, travel to another part of the world and eat the same food and have the exact same experience. I remember a local craft brewer saying he had a lot of respect for Budweiser for making millions of gallons of beer, over the course of decades and having it always be consistent and predictable.

Thank you for highlighting the important work the team at NIST performs. A fine example of functional government and a team dedicated to their work.
This system ends up making everything they control more expensive for the consumer, and gives the consumer less choice. Among many other glaring issues. We can have transparency and certificates etc without total government control. Functional force is still force.
@@adamscrivener9574 I think you may be confusing the NIST with a regulatory body. NIST is a science laboratory setup by Congress to bring US standards up to world standard at the time. Trusted standards allow for improved safety, quality, and a plethora of other things. How the standards are to be applied and who enforces them is another ball of wax.
@@adamscrivener9574 I don't think you understand what NIST is. Without them, businesses would have to spend more money when trying to calibrate their equipment.
Also, just from a broader perspective outside of what NIST does, regulation is necessary. We tried giving businesses free rein during the early 20th century and a bunch of kids lost arms in factory equipment. Businesses have no concern other than money they will hurt or exploit people for profit if left to their own devices.
@@adamscrivener9574 You clearly fall into the weird "GOVERNMENT BAD, NO EXCEPTIONS" camp. Free market capitalism is a race to the bottom. Capitalism needs standards and regulation.
These standards save a ton of money and save a lot of lives. I'm not sure how you came to the conclusion that it makes things more expensive or gives less choice. That makes zero sense. Even with regulations and standards, companies are constantly caught cutting corners which often times result in a loss of life. NIST is a service that is invaluable to the global economy.

Analytical chemist here. From academic research to drug development to drug safety testing, every position I've ever worked makes heavy use of NIST standards (though usually all with their own internal acronyms). These are absolutely vital for almost any calibration or measurement which requires high degrees of certainty.
I’m an analytical chemist, and anyone who works in any lab or in most manufacturing operations definitely knows and appreciates the vital importance of reference standards to calibrate our instruments and ‘test our tests.’ Now NIST isn’t the only game in town that provides SRMs, but you might consider them the ‘standard of standards.’
I deal with having to juggle multiple different steel standards, and let me tell you it's definitely a *_VERY_* detail-oriented job with a lot of spreadsheets. It's astounding how the tiniest changes in composition and forging methods can lead to *_vastly_* different physical characteristics.
Buy coils from two different heat lots of steel from the same mill for the same grade, and those two coils can pass and fail two completely independent lists of other standards. It's the whole reason why "grades" exist: to pigeon-hole a gradient of differences.
Also yes: Charpy Testing is common.........and loud; though not as loud as testing tensile strength, lol.
_(testing the tensile strength you literally just take a bowtie-shape piece of the material and stretch it until it breaks - which is usually accompanied by sounds as loud or louder than a gunshot when it's steel - or at least it's sudden enough that it feels like it's that loud, lol)_
Sounds like my old job.
As someone who understands this video do some of the comments scare you?

This is so interesting! I worked at an environmental testing lab and we did get standards from NIST but it was for our yearly test to maintain our certifications.

There’s a great story you’re (usually) told during NIST orientation for new employees about the Great Baltimore fire of 1904. Lots of FDs from surrounding municipalities and states came to try to help, but at the time, there was no industrial standard for hoses/couplings, so it turned into quite a mess, and more injuries and damage arguably resulted. Those items are now standardized across the country. The HR folks are better storytellers, but still demonstrates the importance of the work of standardization

Great work, Derek, as always.
True story: Back in the early 70s I worked in a radio maintenance shop at McConnell AFB, Ks and some of the radios we maintained were in the HF band (3 - 30 MHz). The NIST runs a radio station call sign WWV which operates on 2.5, 5, 10, 15, and 20 MHz and continuously broadcasts the current time. We used to tune the radios to WWV to confirm that they were tuning properly. We also would set our watches to WWV so we always had very accurate time on our watches. One evening the wife and I were in a mall window shopping (as a junior enlisted we didn't have the money to actually BUY anything) when some guy asked me for the time. I told him the time to the second.
He said "That isn't right!"
To which I replied, "Yes it is. I set my watch by WWV just this morning."
"What's WWV?", he asked.
" It's the national time standard. You know? The same folks who establish the standards for everything in the U.S." I told him.
He then asked, "What makes THAT right?"
Honestly, I didn't have a comeback. How would you answer someone who questions the National Institute of Standards and Technology? (I'm really hoping you answer my question. I was at a loss.)
Lol. Nothing, in a sense. It's just a reliable institution that everyone can go to to help them synchronize their devices that need to be synchronized. You could make your own competing timekeeping service, but good luck making it as reliable, so nobody would bother with it if they really *needed* it.
It’s funny, because there really isn’t anything that makes it right. It’s like how the standard weight of a gram is just a little hunk of metal in a lab and everyone agrees “yeah that’s a gram” because who else is defining a gram? Or how most world currencies only have value due to the people agreeing that they do. It’s a little arbitrary, but it negates arbitration. Which is weird lmao
Thus,the phrase “does anybody really know what time it is. Does anybody really care ?”
In some cases a standard is just an authority meaning we simply have to agree to not disagree. But in fact most standards have agreeable metrics. Ones that would cost more to derive in our own sample than it would to buy a NIST sample and test that. These standards also should be designed so they give you some useful information. Note how NIST only makes these samples at the request of companies.
A little Googling would have revealed that NIST uses THE time standard, a Cesium Atomic clock.
I’m in my undergrad, and I worked on a project that was examining mercury deposition. One of the things that was done for the project was measuring certain samples we collected for mercury. Reference standards were used for that, we used soil standards. It was very interesting to learn about how important these standards are.

i wouldn't agree that it sounds way cooler lol, but it's a field of research i didn't expect to be so interesting for sure
"What's is the ultimate origin of everything that exists?" Is this not a question worth pondering on?
A friend of mine once said: “Better than perfect is standardised”. This video shows that that’s true. Great video! Keep up the good work :)
@gridsleep Standards are perfect because they are standard (thus why SRMs are used as references to determine product integrity), and they are standard because we have deemed them to be adequate enough for a certain product. They are a PERFECT template to ensure the quality of a certain product. So I say that perfection is quite definable.

@@teslacoil5378 Absolutely right! And one can say that standard dust collected in an American standard city is only standard in the US. Global dust must be collected globally, but that probably wouldn't make much sense, except for aliens collecting dust to make "standard inhabited planet dust"
As someone who basically did the same thing for several years, just across the pond (Germany), I'm so glad this important field of research finally get some coverage. The federal institution I used to work for provides the reference alloys for Euro coins, alcohol in water (calibrate breathalyzer's), also a lot of food and environmental samples with toxins or heavy metals and much more.
I worked in the food team and alongside homogenization, stability is one of the major concerns. Grinding it into a nice powder is great for homogenization, but simultaneously creates so much surface area for chemical reactions. And even though they are not used as a food, you don't wanna an Oil to become rancid and so on. So many products are stored in a freezer, but what to do if e.g. the cold chain is broken during transport? The devil is in the detail^^
And that's even before you come to the most difficult question: How to make sure NIST and all the other CRM providers are able to measure correctly themselves? :D
That's where intercomparisons come into play. Also a reason why it's important that every reference is implemented by several national labs. When you are alone with a reference (as is the case with some of what PTB is doing) it's very difficult to be confident that you have not messed something up ;)
how is this institution called in germany?

These are some of the problems that we in the bio fisheries face. You have to take into account the influx and outflow of water and what that water holds. We take our shipping containers almost too seriously. Wipe out all life inside the bag, measure what the water does to the bag and vice versa. Then place the fish into the bag, measure and record. For everything, and I mean like a full 2 days worth of testing for a single fish. Meanwhile that 1 single fish has required about 150 hours of work just to maintain a stable environment. Then when you ask for $3500 for a fish that someone could throw a net out in the river and catch thousands in an hour... Cheezus.. Some people just don't care to realize the effort that was put forth and call just to complain about the price for a perfect lab fish. They don't want one, just call to criticize us for the price of a river minnow. They want a dozen for $10. Sorry, we are not that kind of business.

I've never come across something more mundane and more fascinating than this video.
This video explained how so many things work. People would say they found trace amounts of a certain chemical in a city's water supply, and you'd think "How?" well this is very enlightening. Also always wondered how in shows like CSI they could tell if a bullet was fired from a specific firearm. This is what i subscribed for.
Nah, you’re just stupid dude. A majority of people know that already….
Also, in relation to your specific example about the water supply, a lot of places periodically take samples of their water and store it for later for purposes like that!
I’ve worked at NIST and many other research labs ( university, industry, etc). Scientists at NIST are the most meticulous by far.
Interesting
Have you seen the arguments that A&E911 has made against NIST and there statements about building 7?
In my opinion NIST and our government still have alot of explaining to do about the demolition of the three towers that day. Your statement about scientists being most meticulous made me comment.. If you didn't catch it I think nist is dogwash
How do people at NIST account for things that change their composition with the time? e.g. metals that rust by oxidation or wine/cheeses that "ages"?
I’m a chemist in a consumer goods testing lab, how in the world do you get that job? It’s so fascinating to me
Even as an analytical chemist, where being meticulous about everything is essential to everything I do at work, I could never match the level of NIST scientists. The methods they use are absolutely top notch and I'm grateful for their work. I don't believe my lab buys NIST standards as we're not in the US, but I rely the NIST mass spectral libraries every single day.

@@miguelangelmartinezcasado8935 Exactly.
Why don't we have colour fax machines? Well, we do, except every manufacturer made their own "standard" for it and insisted that anyone else who wanted to use the same "standard", pay for it.

Compare this to Wi-Fi, based on the IEEE 802.11 family of standards: one standard that any company can develop a product to use and know that it will be able to interoperate with billions of other devices out there.
Having one free to use standard lowers the cost of entry into a market, enabling competition and innovation.

Here here. I also poop, and have many times contributed my part to the great, strained effort to achieve new levels of poop standardization.
Woah, such coincidences, I happen to poop as well!
@@anmolagrawal5358 bro everyone does

The Charpy test is indeed an important standard test for steels. It measures the toughness, or resistance to brittle fracture, using a standard notched specimen. Materials prone to brittle fracture are to be avoided (or mitigated). Ductile fracture does not sound so good either, but if something is going to fail, ductile failure is safer and preferable as it requires exceeding design loads to achieve this. Brittle failure is of concern because it can occur at less than design load conditions.
The typical units of measure are energy (absorbed) in Ft-Lbs for imperial unit system, Joules for SI units. Metals and most solid materials become more brittle as temperature is decreased. Higher values measure in this test are better than low values. Brittle high strength steel may yield single digit values, whereas low strength austentic stainless steel may yield 300+ Ft-Lbs, meaning it takes a lot more energy to break it in a notched impact specimen, even though it is not nearly as strong.
Different metal alloys and heat treat conditions will have different temperatures at which they become brittle (Ductile to Brittle Transition Temperature, or DBTT). The temperature at which the test is performed is based on design standards and factors such as the end product's minimum design temperature, and the material's expected DBTT. If the material is produced correctly, it will meet or exceed certain impact energy values at a given temperature. If not, it may produce low values and indicate sub-standard material.
The notch of the specimen, which is the designed point of failure is machined to precise dimensions for the purpose of consistency. I am a Metallurgical Engineer and thought I should delve into sharing my personal understanding of that part of the video.

Charpy is just one way to measure one variable in a steel. Many times in tool steel you don't really care too much about that value, and are looking for wear resistance, such as drawing forms.
Tl;dr I'm naming my next pet Charpy tho
@@scottrackley4457 Good point. Toughness is not a required or necessary property in some materials and some applications. It is in structural and pressure containing products, but typically not in tooling. In fact in tool steels, low toughness often times is very acceptable in order to get the high strength or wear resistance that is required. Hence tool steels when they fail, tend to fail in a brittle manner.
@@Steve_-ob2ne Yes, they turn to gravel and projectiles. Very sharp projectiles.
As someone who is an analytical scientist, this was awesome and so interesting to watch. We use many many many NIST products at my work.
Oh my, I love this video so much. I have long been fascinated and humbled by the standardization efforts in the world. ISO, ANSI, and innumerable technical standards, all of which probably at some point in their development interact with the tangible products NIST produces to actually substantiate their standards. These are the mechanisms that make modern society function. They are foundational to the quality, reliability, and consistency of almost every single moment of our lives. It would be a dream to contribute to that.
NIST is such a good example of government providing services that benefit society as a whole. We undoubtedly get excellent value for money from NIST.
Can you elaborate as to why?
That fat-carb-protein chart was actually fascinating to me, I'd love to see a more detailed and filled out one.
At a glance it looked like actual useful data, unlike the old BS "food pyramid"
Wasn’t that a standard lesson in elementary school? It’s called the food pyramid. Not trying to be mean just wondering if it was in your curriculum because i feel like that’s an important thing for schools to be teaching kids
@@21cabbvge the food pyramid is different! just google it, my english isn't good enough to explain it here haha
but i get your confusion :)
@@21cabbvge i food pyramid is the worse version
@@hfso372 oh right, i forgot the food pyramid is the more basic one with the different food groups going vertically. My bad
Well this answered a years-old question I've always had about nutrition standards. Glad I found this randomly in my feed.
I didn't think this video would be that interesting, but I found it facinating. We don't typically think about how things are measured, just that they are. We always have to compare things to a known quantity (or quality) to measure it properly. We have standard units of measure for weights, time, etc. Why not peanut butter? 🙂
Wow, I'm just learning about this today. I always assumed we must've had something like this but never knew for sure. This makes me feel so much safer!!! Thank you so much NIST people!!!
As always, Derek has found a super interesting place and covered it in an episode brilliantly. Great going, Derek, thank you. :)
More like he watched Tom Scott lol
@@mystic_guardian LMAO
Now they just have to get a sample of everything in there and blend it up to make the most average sample NIST has
I love that institutions like this exist.
It's a large scale, collective enterprise, based on providing a practical service that can improve the quality, reliability and efficiency of nearly every kind of production.
It's a thing that exists, not because it's serves one person or group's selfish interests, but because it has the potential to serve everyone's best interests.
The fact that such institutions exist makes me a little bit less cynical about human nature and potential. Who knows? Maybe our species has a future after all.
Wholeheartedly Agree 💖💖💖
This video is so important, especially these days with all the doubt around societies' systems. There ARE standards, and there ARE checks and balances in place.
Of course, it's called Quality Assurance and almost every company within every industry has it. The problem is the human element, there is no "standard" for good leadership or decision making and that is what causes doubt in very particular systems in society. As far as products are concerned though, the US is certainly above and beyond when it comes to quality and consistency, and it is thanks to organizations like NIST who play a vital role in standardized excellency.
I think these guys just beat the entire German system in being obsessed with norms
Also, this kinda feels like they're the old school "scientist", dealing with absolutely every industry and scientific concept, gaining general knowledge about everything. Generalists instead of specialists
Thanks so much for highlighting NIST!!! Standardization is so important and under appreciated!
my entire family does water treatment and this provided such a massive insight as to why they're always spending thousands on books that contain these standards. i love this video.
edit: i do realize the books they're buying are actually standard procedures (specifically analytical testing), but it's the same idea
The ASTM standards are all put together by volunteer committees and most the time the members actually have to pay ASTM to go to the seminars at which the committee meetings are held, they only costs involved for ASTM are the publishing costs. They're overpriced because ASTM has a monopoly and can get away with charging those ridiculous prices, not because those prices accurately reflect their costs. I've sat on many ASTM committees over the years, it's all a racket.
NIST isn't quite so bad, they're inefficient like all government agencies, but at least their prices reflect their costs.
I love how that guy has a whole list of jokes he's hoping he gets to tell at any given moment 😂
😄😄😄
a list of standard jokes for the standard items
@@JakeInvest So he can accuratelly measure response. This is also where they order canned laughter from. Only thanks to them they can add just the right dose on laugh track or be certain they read test audiences' reaction accurately. (Test audiences of course consist of standard moviegoers. Those are stored frozen coz being exposed to outside influences they change their taste incredibly quickly.)
When government wastes trillions of dollars every year, it MUST be made into a joke, so that people don't cry.
@@trentp151 nist is useful, but I agree government has lots of waste lol
Worked at A Military Calibration Lab (PMEL) as a scheduler. Opened my eyes to not only Standards but how temperature and humidity in the lab is so important. Never appreciated prior to that as a Mechanic how much work went into that sticker on the equipment.
Why would you work for one of the most criminal organizations in the world? For money of course, but you have no principles?
Read it too fast and got "humility in the lab" ... hehe that too.
Takes like 6 months to get a torque wrench back from you guys
How amazingly intriguing! Living in the 3rd world it is some comfort to know that "the bar is being identified and set"somewhere on the planet. Paul, Johannesburg
Nothing excites me more than the work NIST does, thank you for bringing attention and focus to their work! Calibration is such a foundational aspect of our modern day experience and needs to be communicated as much as possible. In the field of epistemology, NIST and other standards organizations are as good as it gets.
I mean, it's interesting - fascinating, even. But "nothing excites me more"? That's a weird place to be. You should probably try to get a job there...
@@andoletube Nah man, I totally get it. NIST (and other standardisation labs) are like a nexus of every modern manufacturing process. Our world in a warehouse. Endlessly fascinating imo
I agree you should get a job there though, Ryzeke 😛
I literally drive by NIST like 8 times a day as a Paramedic in the area. Never knew what they actually did there.
As a QC Chemist, I have used NIST standards and this is a a fantastic explanation of why they are so expensive - with great visuals!🥜🥜🥜🥜🥜🥜🥜
