A decade or two ago a bunch of power customers in north-central British Columbia, Canada, complained that their clocks were very inaccurate. Lots of them were late for work. The electric company put some clever people on the problem to work out that the power grid was consistently providing power at 59.5 Hz when the customers’ clocks were presuming a steady 60 Hz. None of the other appliances cared about the slight deviation.
Anton:You might still be able to get WWFV or WWV. One is at Ft Collins COl. The other is someplace in Hawaii. There used to also be one in CANADA, but I'm not sure if it's still operating. The American ones are operated by the National Institute for Time & Standards. They X-mit on 20 mega cycles, 15, 10, 5, & 2.5 mega cycles. The one in Canada X-mits someplace around the 41 meter band,(or slightly above that). I don't really pay much attention to the Canadian one (near 41 meters) because they X-mit in Frog🐸.

Not a problem any more! In the US (and I suspect Canada and Mexico too) the frequency average is intentionally maintained so that this doesn't happen and has been that way since the 1930s or something. The variation during the day can slip a little but, but they track it and adjust it so the long term average is maintained. Wikipedia has a good article on this but basically whenever the frequency has slipped long enough for the time to be off by more than a handful of seconds, they adjust it to bring it back to where it should be. Wherever you live in the US your mains-synchronized clock will stay within 10s of the time you set it to as long as there is not a power outage.
@@alzeebum I had to create a routine in my analog clock application to keep synchronization with the computers real time clock. Unfortunately windows systems don't offer direct access to the real time clock in nanoseconds. I had to pace the speed of the ticks over a 1 second period by adjusting the ticks +/- fast/slow to keep it to 60 ticks per second (within about 10 milliseconds per 1/60 of a second). It auto adjusts (compensates) in real time.
@@alzeebum, 10 s! I would turn down that kind of gift. That's actually enough to miss the bus. I know, because I used these "atomic" wrist watches in Norway, controlled from a transmitter in Germany. I arrived at the bus stop precisely 10 seconds before the bus was scheduled. The bus drivers knew I had these clocks, and made sure their clocks were accurate too.
3:55 Quartz crystals are actually like tiny tuning forks. What makes them special is you can both excite them into their resonance and measure said resonance using electricity. They actually kinda look like tiny tuning forks under a microscope. Factories will use lasers to trim material off the "tynes" until the frequency is correct. 32 kHz is a common frequency because it's 2^15 cycles per second. It's easy to count the cycles with digital logic to produce an accurate clock.
To be exact, it's 32,768 Hz, which is as you said, 2^15. The frequency is so convenient for computers that they are used to count the time in every PC compatibles since the introduction of IBM PC-AT.
not every quartz resonator looks like tuning fork, only "tuning fork" type :) Most of them are quite different from that. Also, very old version of electric clock resonator was metallic tuning fork actually, but with two coils (excitation and feedback)
I had a radio clock all the way back in the 1980s. Oh, wait. It was a clock radio. It was digital, though. It had numbers on plastic tabs that flipped when each minute changed. It went "clack!" And at the top of each hour, it went "clack-clack-clack!" It had knobs for tuning in the radio, too. Very advanced! It had a wood finish.
Mannnnnnn 😂😂 I swear I was laughing out loud for 30 seconds !! I wanted to write this message to tell you that I really love watching your videos ! From going to sleep or watching it really seriously, I found your work really understandable and to the point. thats why your the best. Keep up the good work Love from France !
In ROC (South Korea) you are indeed in range of China's and Japan's transmitters that Casio's Waveceptor MultiBand6 and other worldwide receiver watches are equipped for :) Wall-clocks I have not seen for multiple frequencies and codes though, so you were right pulling the brakes there :)
I guess I have a lot of people that believe I’m a nerd. I’ve got several atomic clocks scattered around the house that I’ve received as gifts throughout the years.
She should have got you a Wonderful Person t-shirt that you can find in the description. Great video. I never fail to learn something new from your channel.
As my friends and I are nerdy and dislike these awkward gifting situations, some of us maintain a wish list of geeky goodness. It also provides fun topics of conversation.
The superposition affected by gravity issue is very important. The proposed experiment seems doable and not particularly expensive and would put laboratory experimentation --small science--back on the map for funding. Thanks for finding it and reporting it. Unfortunately, the article is behind a pay wall for all but those with university affiliation. Please cite a free pre-print.
Most of Europe gets this time radio signal from the German DFC77 radio station at 77.5 kHz. I certainly do even as I live over 1000 km from the source of the signal.
3:52 The frequency of the Power grid can actually slightly change by up to +/-180mHz (Microhertz) here in Europe. And yes that makes all clocks that depend on the Power grid to measure time go faster or slower...
True but those fluctuations average out - in fact the grid frequency deviations are recorded and a procedure known as TEC (Time Error Correction) is implemented which deliberately raises or lowers the frequency depending on whether the accumulated error is low or high to exactly reverse any time error. So long term it's actually a very accurate time reference
Anton, smile, say thank you, how thoughtful! And use it. Sometimes the gift means more to the giver than the recipient. From one wonderful person to another.
I read about this today and i thought it was amazing... but then Anton made a video about it and made it wonderfull. I thought it was just a better clock reading that article but it seems it's much much more than that.
Sending love to you and your family. This one was amazing, i learned so much and will enjoy researching different atomic clock ideas. Your birthday story was wonderful (and relatable!). Thank you Anton.
I thought you would be talking about a discovery I read about yesterday, about an ultra-precise measurement of a transition in the hearts of thorium atoms, where they state "The discovery of a laser-controllable transition in the atomic nucleus of thorium-229 marks the dawn of the “nuclear clock.”. They use an ultraviolet laser. They realized that a clock based on thorium-229 atoms would be immune to much of the background interference that plagues the best atomic clocks since it involves energy transitions in the nucleus instead of in the electrons surrounding the nucleus. See the article in Quanta Magazine - "The First Nuclear Clock Will Test if Fundamental Constants Change". And oh, btw: You can get precise time from a GPS signal, anywhere on the planet. You don't need to depend on NIST. There must be clocks available based on this principle. Most every cell phone these days has access to precise time via the GPS signal they process, but I don't know why they don't give you the time derived from that.
This is exciting. Quantum Mechanics is well above my skill level, but the ability to measure time dilation at quantum level has got to move science forward. Thank you Anton.
I worked for a telecom that was responsible for the T-1 fiber line to the Atomic Clock--a rather dim employee in our team had that account in her purview--she got an order to change the parameters of the T-1 access and botched the service orders which shut down the circuit--all hell broke loose--fortunately, there were engineers, technicians and others who managed to get the Atomic Clock back on line . . .
Thanks for keeping me informed, Anton! As a young 20 year old I am always absolutely stunned at some of the things we're *still* finding out. Can't wait to see what's coming in the next 60-70 years
Some buildings block low frequency RF with metallic studs forming a coarse Faraday cage.. . Many power converters from lights to chargers to your neighbor's solar system can obliterate what's left.
She didn't get you nothing. She got you time and space. You don't need to store the unnecessary gift, you don't need to spend spares income purchasing another thing. She got you the perfect gift.
Cool stuff, sir. As to practical uses, there's a story about Michael Faraday (the GOAT of physics) that he was talking once with someone the government who asked him what could possibly ever be done with electric motors. Faraday told that was going to be achieved by later researchers, but that it didn't matter, because he felt certain that the government would come up witha way tax it. Wonderful work, Anton.
@@KLRJUNE Wait, don't tell me you're one of those people who look at the Pelosi's or Obama's with their net worth of many millions of dollars and think that didn't come from you. 😂😂🤣🤣 It is called laundering.
A far more interesting experiment would be about the validity of entangled particles transferring their state to the other particles instantly. If the "lower" particle is affected by time dilation more than the upper particle, that would dispell true quantum entanglement. The entangled particles would be proven to have separate inertial reference frames and therefore couldn't transmit their state instantly to the other particle.
Yes, very interesting. There could be a slight delay observed in the lower particle materializing as spin up after the higher particle has already materialized as spin down.
@chriskennedy2846 yes exactly. I'm still pondering the implications of that in regards to the properties of entanglement. It's differs substantially from experimenting with the superposition of a single particle as mentioned in the video. I will also need to spend some time thinking about that experiments implications to quantum mechanics and times effect there, as normally "time" is somewhat glossed over in quantum mechanics. Does "time" become a probability function in that experiment ??? Very interesting topic indeed !
@@John-ir2zf quantum nonlocality is a proven fact( if you rule out some interpretations) it is way faster than light at least, it should be instantaneous to make any sense.
You misunderstand entanglement. Nothing is transferred instantly. When one particle is observed, you instantly know the state of the other simply because it is always the opposite state. No data is exchanged. Nothing is changed about the unobserved particle.
With the birthday present, it's probably better to say thank you and pretend that you like it! It will still work as an ordinary (quartz) clock. Domestic relations are much harder than physics.
Thinking of QFT. The particle in superposition should oscillate uniformly because each instance shares the same position in the field. What's important to their time is not their distances from earth, but how they are relative to you, the measurer. One field, one particle, one you to perceive instances in superposition sharing the same clock.
I am celebrating because this is the first time I have more knowledge about the subject than you do, but you did very well. another good explenation, thank you!
Whenever Anton is trying to connect to the audience ( smiling, talking in a joking manner, etc ) he's weirder than the lizard founder of Facebook and the video looks awkward like your friend is trying to tell a joke but he doesn't now how to deliver it And I'm not even a hater, I've been watching since What the Math
but they have the same signal in SEA, so yea, it would work in South Korea as well. the Casio Oceanus line uses the same calibrating signal, and it's built for Japan.
Wow! What a time to be alive! And I'm not saying this lightly. This is a really great work. Looking forward to see the superposition of relativistic effect 😃
This feels like a breakthrough waiting to happen. If the experiment can be successful in that it can measure accurately and be proven that it measured accurately, any result is a breakthrough. This is a question that even a yes or no answer would make theoretical physicists have a hayday, let alone the how of a yes or no. If they didn’t experience different time dilation, what dilation did they experience? If they did how does that work given they are the same particle? Really juicy info, makes me excited for the next few decades of theoretical physics. We had a barrier for so long where any measurement was impossible but the exponential improvement of measurement technology has provided new opportunities and will continue to provide new opportunities at a growing rate in the future. I feel like a great example of that improvement is how we got a picture of a black hole and that was a huge thing even though it was just a blur with a dark spot in the middle, and then just a few years later we have a picture of a black hole that includes the spiraling of the excretion disk.
We can now use these clocks to test the theory of relativity! I remember when they put an atomic clock on a plane in Denver and left one on the ground as the plane, using the rotation of the Earth, along with its own propulsion to test the theory. After circumnavigate the Earth, the two clocks were different. Does no one remember this? I think its must have been 40 years ago??? Maybe 50. We are so smart today.
Shm... You got one of the most valuable gifts of all ~ a home with someone that loves you! So many others could only wish to be so gifted! (Pull back and take a "humane" view for a moment!)
Speaking of frequencies at an atomic level.. One of the things scientists forgot to include in the calculations for the big bang were how sound would travel through the mediums of which it was developed in the same notion. Many sonical, electro-chemical marvels of pressure they have yet to truly dive in to. One of the key factors was that "there is no sound in space" dismissed the idea.
To think there were a rainbow of bandwidths clashing from every direction and dimensional theory of possibility where-about the existence of such formed from the lack there-of with irradiation in to near-infinite particles and atomic containment of charges, capable of engaging with others, compounding geometrical integrity, in-turn, churning mechanical energy and simulating other instruments, their own mediums, and how those in size, shape, frequency, amplitude, charge, and mass inherently shaped the early ancient galaxies, and perhaps the matter's own resilience to time, space, and even exerting its own pressure and persistence through potential properties of current to the latter.
@3:59. A 32.768Khz tuning fork crystal is typically made to oscillate at that frequency only at a specific temperature such as 25°C. At other temperatures, the frequency variation is typically -0.036ppm / (Tc-25)^2, Tc being the crystal temperature in Celsius. So, unless that drifting is compensated somehow, if you take your crystal watch off of your wrist, it may slow down considerably.
this is so exciting, quantum gravity has been the biggest mystery in unifying classical and quantum mechanics, being able to have concrete proof that quantum particles either do or dont experience gravity is going to be a massive step to overcoming this hurdle
In the mid 70s I was a radio maintenance technician in the USAF working in the HF radio maintenance shop. To check the operation of our radios we would tune to WWV, the NIST radio station which operated on 5, 10 and 15 megahertz sending out time hacks. It would a few seconds before the top of the minute it would announce that at the tone the time would be so-and-so Coordinated Universal Time. We would set our watches by WWV and so our watches were always really close to UTC. One evening my wife and I were at a Mall when a guy asked me what time it was. Whem I told him he said, "That can't be right!" to which I replied, "It is. I set my watch by WWV this morning." He then asked what WWV was and after I told him it was the official time for the U.S. he exclaimed, "What makes that right?". I was at a loss for words. How do you explain what makes the National Institute of Standards and Technology right? How would you have answered him? Anton? Anybody? BTW I have clocks very similar to what you showed hanging in my kitchen and also in my man cave/computer room. I also have my PC set its clock with the NIST via an app. Plus I have a wrist watch made by Casio that sets itself from the NIST every 8 hours. I guess I like knowing the correct time. FYI, Anton, I think there is a version of that Casio watch that works in the Far East. It's called the "Waveceptor" and is available on Amazon. I love your videos. Keep up the great work!
First off, thank you as always for a really interesting and informative vid. That being said, you're a smart guy with a lot of knowledge about a lot of stuff, and you have a channel dedicated to explaining that stuff to the multitudes of laymen out there on the internet in an easy to understand way. So yes, you very much are a nerd. Never understood why that was ever considered a bad thing, or even to this day is somewhat considered a negative label.
In the US, AC power was made so any clock plugged into the wall would be right to within 3 seconds. Not 3 seconds / year. Just 3 seconds. Basically, the old timely plug-in-the-wall clocks were as accurate as the atomic clocks. The problem happened when clocks started using the DC ("wall wart") power supplies. *Then* they needed the radios.
Nonsense, where did you hear that baloney. An electric clock will vary 2 to 20 minutes per year and some parts of our nation have more variations than others. Texas happens to be the bests since isolated. The atomic clock that are the reference for WWV stay within 100 ns of UTC and 20 ns of the national time standard, you can't say that about the 60 Hz mains frequency even within a day.
@@RWZiggy it is possible you've used poorly made clocks. There are specifications and companies with large motors won't damage them. I've never had to re-set one of those clocks. TVs used the power grid for timing for decades.
Beginning reminded me how much I like Stanford Research Systems (SRS) frequency standards. Their rubidium + GPS + OCXO is so good for demanding audio uses. Though the GPS part isn't really needed for audio, it's so long time window standard helper.
Actually clocks that use the AC line frequency are better at tracking time than quartz crystal clocks (at least in the USA) because the power company keeps track of the number of cycles it produces every day and adds or subtracts cycles at the end of the day so the number is always correct (24h*60m*60s*60Hz). Quartz crystal clock can have a more accurate second but any error accumulates and will gain or lose 15 seconds per 30 days.
Meanwhile, laptops with thousand dollar processors can gain or lose 5 minutes in a month or two when they lose access to ntp... It's as if they are terrible on purpose!
@@rogerphelps9939 Was pissed off when I bought a cheap VCR before they were phased out: and it lost 15 seconds per week. I guess they always assumed you could get the time from the cable company or something.
The atom farther from the earth will experience faster time than the atom closer to the earth. The higher gravity slows time, as is demonstrated near a black hole.
An interesting thought is that a hypothetical Atomic Clock placed in the center of the Bootes Void should be one of the oldest places in the Universe (barring an unknown amount of Dark Matter there), because more seconds will have elapsed there.
Yes…but a clock in orbit, further from Earth, is moving fast. The faster the clock moves the slower it ticks compared to a stationary observer on Earth. Two corrections then: distance from a source of gravity, speed with respect to an observer.
It wont, the atom is just being measured millions of times up and down, it is not actually in two places cause the superposition is broken. The small probability cloud is moving up and down.
@@CarFreeSegnitz yes, hence why orbiting astronauts return slightly younger than if they had stayed on earth. The higher velocity relative to the staring and ending point.
@@samgragas8467 I’m commenting on his experiment where he has two distinct hyper cooled atoms, one above the other. He wrongly stated that the higher one would register slower time than the lower one. As I said, this is incorrect.
It's not just gravity that affects the passage of time for each of us. One twin walks his whole life, the other twin stays in one place, and time passes slower for the twin that moves.
I had a job where I set the atomic clock at an army installation in far south area of Japan. We would listen for the WWVB signal on 10 MHz, which is what these clocks claim to be receiving, not 60 kHz. We didn’t compare the arrival time of that signal with the clock, pulse put out by our clock, to sync them. That signal was also broadcast on several other frequencies, including 15 megs 20 megs and I think 7.5 megs. I really see no reason why you should not be able to receive it in South Korea. Which really threw me when you said that is where you live.
Wow. I always thought "how can we possibly measure quantum gravity given how weak it is?" But the idea of using high-precision time to measure gravity is kind of mind-blowing.
Better get that clock, you might be 2 milliseconds late for that meeting. Rocky & Bullwinkle went to "Tic-Tock-Tech," so they knew what time is or was a guess.
This seems like a pretty big deal! Anything getting us closer to connecting Einsteinian physics with Quantum. Also, the idea of being able to accurately measure the superposition of quantum particles. Kinda crazy. I mean, quantum physics makes almost no sense to me anyway, but sure would be nice to have some of these mysteries cleared up!
I feel you dude. You don't want your s.o. to waste money on something stupid and at the end it's frusttrating for both. Next time wish for something or accept whatever and feel happy that you made your s.o. happy. It helps.
Follow up question for Anton, or anyone smart. Scenario in vid: The Yb atom is successfully placed in a superposition, then it's grabbed by a laser tweezer, then another laser tweezer is positioned near, which then grabs the same Yb atom at another point, because it's acting like a wave, kinda. If I'm understanding correctly, when the superposition is "broken" both laser tweezers will have a Yb atom in them. The same atom, but now twice. Which is all well and good, but isn't that technically creation of matter? Or is the second atom not permanent? Or are we working with such small increments of time none of this matters cause quantum gonna quantum? I feel like I'm missing something, maybe when the superposition is broken, there is only one atom again, or something relating to the observer effect? Or at the end of the experiment there truly are two Yb atoms now and it's similar to how temporary/virtual(?) particles can borrow energy from the vacuum? The experiment itself can't be providing enough energy for creation of a Yb atom, unless it does because it's focused on such a small point, but I don't think this is the case. What gives?
Breaking the superposition just leaves you with one trapped atom. The experiment would have to be conducted with the superposition intact, carefully measuring the small differences between the two locations without actually determining the 'true' location of the atom.
Great, thanks. That makes much more sense. Side question, do you happen to know which trapped atom stays and which one disappears? After the superposition is broken. Disappears is the wrong word, but I think you follow what I mean. If we designate them as Yb1 (the initial atom) and Yb2 (the newly captured superposition "version"), when the super position is broken is Yb1 always the one that remains? Or can Yb1 "leave" and Yb2 remains captured?
Anton being hard to shop for is actually kind of funny

@@lestergillis8171does anybody know what this guy is talking about?
@@alzeebum I had to create a routine in my analog clock application to keep synchronization with the computers real time clock. Unfortunately windows systems don't offer direct access to the real time clock in nanoseconds. I had to pace the speed of the ticks over a 1 second period by adjusting the ticks +/- fast/slow to keep it to 60 ticks per second (within about 10 milliseconds per 1/60 of a second). It auto adjusts (compensates) in real time.
@@alzeebum, 10 s! I would turn down that kind of gift. That's actually enough to miss the bus. I know, because I used these "atomic" wrist watches in Norway, controlled from a transmitter in Germany. I arrived at the bus stop precisely 10 seconds before the bus was scheduled. The bus drivers knew I had these clocks, and made sure their clocks were accurate too.
3:55 Quartz crystals are actually like tiny tuning forks. What makes them special is you can both excite them into their resonance and measure said resonance using electricity.
They actually kinda look like tiny tuning forks under a microscope. Factories will use lasers to trim material off the "tynes" until the frequency is correct. 32 kHz is a common frequency because it's 2^15 cycles per second. It's easy to count the cycles with digital logic to produce an accurate clock.
To be exact, it's 32,768 Hz, which is as you said, 2^15. The frequency is so convenient for computers that they are used to count the time in every PC compatibles since the introduction of IBM PC-AT.
not every quartz resonator looks like tuning fork, only "tuning fork" type :) Most of them are quite different from that.
Also, very old version of electric clock resonator was metallic tuning fork actually, but with two coils (excitation and feedback)
You're short about 768 Hz
I had a radio clock all the way back in the 1980s.
Oh, wait. It was a clock radio. It was digital, though. It had numbers on plastic tabs that flipped when each minute changed. It went "clack!" And at the top of each hour, it went "clack-clack-clack!"
It had knobs for tuning in the radio, too. Very advanced!
It had a wood finish.
Thank you Mrs. Petrov, for the thoughtful idea that led to this really cool video.
Mannnnnnn 😂😂 I swear I was laughing out loud for 30 seconds !! I wanted to write this message to tell you that I really love watching your videos ! From going to sleep or watching it really seriously, I found your work really understandable and to the point. thats why your the best.

In ROC (South Korea) you are indeed in range of China's and Japan's transmitters that Casio's Waveceptor MultiBand6 and other worldwide receiver watches are equipped for :)
Wall-clocks I have not seen for multiple frequencies and codes though, so you were right pulling the brakes there :)
Plenty of Gshocks have Multiband 6 too.
Such a great thing to have, atomic time correct to the second, always.
My wife has been “about” to buy me a bench grinder for a decade, I bought myself one 7 years ago.
😂
I'm glad you finally got your bench grinder.
Its a normal thing. Its just because you're taller than your wife. Its the same as the GPS effect
Don't tell her. Then return it and buy a bench for your grinder.
I suppose a man could live without a bench grinder, but, is that really living?
I guess I have a lot of people that believe I’m a nerd. I’ve got several atomic clocks scattered around the house that I’ve received as gifts throughout the years.
have you ever compared their accuracy against each other? Kinda curious just how in sync they are

The superposition affected by gravity issue is very important. The proposed experiment seems doable and not particularly expensive and would put laboratory experimentation --small science--back on the map for funding. Thanks for finding it and reporting it.

I can turn off my internet for the rest of the day because I won't read a better comment.
3:52 The frequency of the Power grid can actually slightly change by up to +/-180mHz (Microhertz) here in Europe. And yes that makes all clocks that depend on the Power grid to measure time go faster or slower...
True but those fluctuations average out - in fact the grid frequency deviations are recorded and a procedure known as TEC (Time Error Correction) is implemented which deliberately raises or lowers the frequency depending on whether the accumulated error is low or high to exactly reverse any time error. So long term it's actually a very accurate time reference
MicroHertz, not millihertz?
A few years ago Serbia was causing the frequency to be off. Tom Scott did a video on it.
mHz is millihertz, μHz is microhertz

Anton, smile, say thank you, how thoughtful! And use it. Sometimes the gift means more to the giver than the recipient. From one wonderful person to another.
I read about this today and i thought it was amazing... but then Anton made a video about it and made it wonderfull.
I thought it was just a better clock reading that article but it seems it's much much more than that.
Sending love to you and your family. This one was amazing, i learned so much and will enjoy researching different atomic clock ideas. Your birthday story was wonderful (and relatable!). Thank you Anton.
I thought you would be talking about a discovery I read about yesterday, about an ultra-precise measurement of a transition in the hearts of thorium atoms, where they state "The discovery of a laser-controllable transition in the atomic nucleus of thorium-229 marks the dawn of the “nuclear clock.”. They use an ultraviolet laser. They realized that a clock based on thorium-229 atoms would be immune to much of the background interference that plagues the best atomic clocks since it involves energy transitions in the nucleus instead of in the electrons surrounding the nucleus. See the article in Quanta Magazine - "The First Nuclear Clock Will Test if Fundamental Constants Change". And oh, btw: You can get precise time from a GPS signal, anywhere on the planet. You don't need to depend on NIST. There must be clocks available based on this principle. Most every cell phone these days has access to precise time via the GPS signal they process, but I don't know why they don't give you the time derived from that.
This is exciting. Quantum Mechanics is well above my skill level, but the ability to measure time dilation at quantum level has got to move science forward. Thank you Anton.
I worked for a telecom that was responsible for the T-1 fiber line to the Atomic Clock--a rather dim employee in our team had that account in her purview--she got an order to change the parameters of the T-1 access and botched the service orders which shut down the circuit--all hell broke loose--fortunately, there were engineers, technicians and others who managed to get the Atomic Clock back on line . . .
We will definitely need more accurate clocks when we go time travelling.
Thanks for keeping me informed, Anton! As a young 20 year old I am always absolutely stunned at some of the things we're *still* finding out. Can't wait to see what's coming in the next 60-70 years
I’ve had an atomic clock for about 10 years, it sometimes get the time wrong, or takes hours to a day to pick up the signal.
Some buildings block low frequency RF with metallic studs forming a coarse Faraday cage.. . Many power converters from lights to chargers to your neighbor's solar system can obliterate what's left.

Cool stuff, sir.
As to practical uses, there's a story about Michael Faraday (the GOAT of physics) that he was talking once with someone the government who asked him what could possibly ever be done with electric motors. Faraday told that was going to be achieved by later researchers, but that it didn't matter, because he felt certain that the government would come up witha way tax it.
Wonderful work, Anton.

@@Deletirium I think we can take that as a certainty. But this channel has a wide reach, and Faraday is not known as well as he should be.
A far more interesting experiment would be about the validity of entangled particles transferring their state to the other particles instantly.
If the "lower" particle is affected by time dilation more than the upper particle, that would dispell true quantum entanglement.
The entangled particles would be proven to have separate inertial reference frames and therefore couldn't transmit their state instantly to the other particle.
Yes, very interesting. There could be a slight delay observed in the lower particle materializing as spin up after the higher particle has already materialized as spin down.
@chriskennedy2846 yes exactly. I'm still pondering the implications of that in regards to the properties of entanglement.
It's differs substantially from experimenting with the superposition of a single particle as mentioned in the video.
I will also need to spend some time thinking about that experiments implications to quantum mechanics and times effect there, as normally "time" is somewhat glossed over in quantum mechanics.
Does "time" become a probability function in that experiment ???
Very interesting topic indeed !
@@John-ir2zf quantum nonlocality is a proven fact( if you rule out some interpretations) it is way faster than light at least, it should be instantaneous to make any sense.
You misunderstand entanglement. Nothing is transferred instantly. When one particle is observed, you instantly know the state of the other simply because it is always the opposite state. No data is exchanged. Nothing is changed about the unobserved particle.
@@samgragas8467 No, nothing is faster than light as light travels at the speed of causality.
Happy belated birthday Anton. Love the channel buddy. Keep up the great content!
With the birthday present, it's probably better to say thank you and pretend that you like it! It will still work as an ordinary (quartz) clock. Domestic relations are much harder than physics.
Thinking of QFT. The particle in superposition should oscillate uniformly because each instance shares the same position in the field. What's important to their time is not their distances from earth, but how they are relative to you, the measurer. One field, one particle, one you to perceive instances in superposition sharing the same clock.
In 30 billion years spacetime will have stretched more than a second

Hotel Coral Essex?
This is an incredible episode. It blows my mind to think what science will be like in 100 years
This feels like a breakthrough waiting to happen. If the experiment can be successful in that it can measure accurately and be proven that it measured accurately, any result is a breakthrough. This is a question that even a yes or no answer would make theoretical physicists have a hayday, let alone the how of a yes or no. If they didn’t experience different time dilation, what dilation did they experience? If they did how does that work given they are the same particle? Really juicy info, makes me excited for the next few decades of theoretical physics. We had a barrier for so long where any measurement was impossible but the exponential improvement of measurement technology has provided new opportunities and will continue to provide new opportunities at a growing rate in the future. I feel like a great example of that improvement is how we got a picture of a black hole and that was a huge thing even though it was just a blur with a dark spot in the middle, and then just a few years later we have a picture of a black hole that includes the spiraling of the excretion disk.
That entire opening is why I love this guy! 😂
We can now use these clocks to test the theory of relativity!
I remember when they put an atomic clock on a plane in Denver and left one on the ground as the plane, using the rotation of the Earth, along with its own propulsion to test the theory. After circumnavigate the Earth, the two clocks were different.
Does no one remember this? I think its must have been 40 years ago??? Maybe 50. We are so smart today.
Thank you, Anton. Great story and a great explanation about the clocks!
Shm... You got one of the most valuable gifts of all ~ a home with someone that loves you! So many others could only wish to be so gifted! (Pull back and take a "humane" view for a moment!)
Speaking of frequencies at an atomic level..
One of the things scientists forgot to include in the calculations for the big bang were how sound would travel through the mediums of which it was developed in the same notion. Many sonical, electro-chemical marvels of pressure they have yet to truly dive in to. One of the key factors was that "there is no sound in space" dismissed the idea.
To think there were a rainbow of bandwidths clashing from every direction and dimensional theory of possibility where-about the existence of such formed from the lack there-of with irradiation in to near-infinite particles and atomic containment of charges, capable of engaging with others, compounding geometrical integrity, in-turn, churning mechanical energy and simulating other instruments, their own mediums, and how those in size, shape, frequency, amplitude, charge, and mass inherently shaped the early ancient galaxies, and perhaps the matter's own resilience to time, space, and even exerting its own pressure and persistence through potential properties of current to the latter.
Crystals can be shaped and tuned to do a lot of RF frequencies it's how radios work..
It's a common timer frequency crystal used in real time clocks :)
@3:59. A 32.768Khz tuning fork crystal is typically made to oscillate at that frequency only at a specific temperature such as 25°C. At other temperatures, the frequency variation is typically -0.036ppm / (Tc-25)^2, Tc being the crystal temperature in Celsius. So, unless that drifting is compensated somehow, if you take your crystal watch off of your wrist, it may slow down considerably.
this is so exciting, quantum gravity has been the biggest mystery in unifying classical and quantum mechanics, being able to have concrete proof that quantum particles either do or dont experience gravity is going to be a massive step to overcoming this hurdle
German here, we have the same service. Love it.
In the mid 70s I was a radio maintenance technician in the USAF working in the HF radio maintenance shop. To check the operation of our radios we would tune to WWV, the NIST radio station which operated on 5, 10 and 15 megahertz sending out time hacks. It would a few seconds before the top of the minute it would announce that at the tone the time would be so-and-so Coordinated Universal Time. We would set our watches by WWV and so our watches were always really close to UTC. One evening my wife and I were at a Mall when a guy asked me what time it was. Whem I told him he said, "That can't be right!" to which I replied, "It is. I set my watch by WWV this morning." He then asked what WWV was and after I told him it was the official time for the U.S. he exclaimed, "What makes that right?". I was at a loss for words. How do you explain what makes the National Institute of Standards and Technology right? How would you have answered him? Anton? Anybody?
BTW I have clocks very similar to what you showed hanging in my kitchen and also in my man cave/computer room. I also have my PC set its clock with the NIST via an app. Plus I have a wrist watch made by Casio that sets itself from the NIST every 8 hours. I guess I like knowing the correct time. FYI, Anton, I think there is a version of that Casio watch that works in the Far East. It's called the "Waveceptor" and is available on Amazon. I love your videos. Keep up the great work!
8:25 Using 'a Yeti' in a cold environment makes sense.
First off, thank you as always for a really interesting and informative vid. That being said, you're a smart guy with a lot of knowledge about a lot of stuff, and you have a channel dedicated to explaining that stuff to the multitudes of laymen out there on the internet in an easy to understand way. So yes, you very much are a nerd. Never understood why that was ever considered a bad thing, or even to this day is somewhat considered a negative label.
In the US, AC power was made so any clock plugged into the wall would be right to within 3 seconds. Not 3 seconds / year. Just 3 seconds.
Basically, the old timely plug-in-the-wall clocks were as accurate as the atomic clocks. The problem happened when clocks started using the DC ("wall wart") power supplies. *Then* they needed the radios.
Nonsense, where did you hear that baloney. An electric clock will vary 2 to 20 minutes per year and some parts of our nation have more variations than others. Texas happens to be the bests since isolated. The atomic clock that are the reference for WWV stay within 100 ns of UTC and 20 ns of the national time standard, you can't say that about the 60 Hz mains frequency even within a day.
@@RWZiggy it is possible you've used poorly made clocks. There are specifications and companies with large motors won't damage them. I've never had to re-set one of those clocks.
TVs used the power grid for timing for decades.
I loved that intro, it was educational and endearing!
It makes me so happy whenever these studies are done at CU Boulder. Sko buffs!
This is super interesting and something I've been wondering for years. I'm glad someone is finally looking at it.
Thanks for sharing this, something to look forward to in the near future.
Beginning reminded me how much I like Stanford Research Systems (SRS) frequency standards. Their rubidium + GPS + OCXO is so good for demanding audio uses. Though the GPS part isn't really needed for audio, it's so long time window standard helper.
Actually clocks that use the AC line frequency are better at tracking time than quartz crystal clocks (at least in the USA) because the power company keeps track of the number of cycles it produces every day and adds or subtracts cycles at the end of the day so the number is always correct (24h*60m*60s*60Hz). Quartz crystal clock can have a more accurate second but any error accumulates and will gain or lose 15 seconds per 30 days.
My 20 year old Casio has only added a minute since I set it a year and a half ago. so that's only like 3 seconds a month.
In my experience they are a lot more accurate than that. When did you last need to adjust your electronic watch?
Meanwhile, laptops with thousand dollar processors can gain or lose 5 minutes in a month or two when they lose access to ntp... It's as if they are terrible on purpose!
Temperature compensated quartz watches will run at a few seconds plus or minus per year.
@@rogerphelps9939 Was pissed off when I bought a cheap VCR before they were phased out: and it lost 15 seconds per week. I guess they always assumed you could get the time from the cable company or something.
Blown away by Anton. And “Time”.
Great video, I’m excited to see some experiments coming to finally begin to probe the connections between relativity and quantum mechanics.
This was an especially interesting episode, Anton. I hope you update this when you're able.

Happy Birthday (a while back) !!!
You've got attention and desire to give, Anton😊 That the best birthday present🎁
The atom farther from the earth will experience faster time than the atom closer to the earth. The higher gravity slows time, as is demonstrated near a black hole.
An interesting thought is that a hypothetical Atomic Clock placed in the center of the Bootes Void should be one of the oldest places in the Universe (barring an unknown amount of Dark Matter there), because more seconds will have elapsed there.
Yes…but a clock in orbit, further from Earth, is moving fast. The faster the clock moves the slower it ticks compared to a stationary observer on Earth. Two corrections then: distance from a source of gravity, speed with respect to an observer.
It wont, the atom is just being measured millions of times up and down, it is not actually in two places cause the superposition is broken. The small probability cloud is moving up and down.
@@CarFreeSegnitz yes, hence why orbiting astronauts return slightly younger than if they had stayed on earth. The higher velocity relative to the staring and ending point.
@@samgragas8467 I’m commenting on his experiment where he has two distinct hyper cooled atoms, one above the other. He wrongly stated that the higher one would register slower time than the lower one. As I said, this is incorrect.
Mrs. Petrov : "Fine. You got nothing for being so difficult."
😅
Haha dude! I would love to jear how your frist date with your wife went!
This was your best intro ever! :-D
It's not just gravity that affects the passage of time for each of us. One twin walks his whole life, the other twin stays in one place, and time passes slower for the twin that moves.
thats an open ended statment.. walks in water.. same material?.. up hill, down.. clarify
Happy Birthday! Hope you at least got a cake.
Sometimes, Anton, knowledge comes at a price. Sometimes, that price is guiding unwittingly bad presents in to no presents 😭
Wow. I live in Alaska. Looks like the clock wouldn't work here either! Great discovery to share -- thank you!
Wow great story and explanation. What amazing times we live in.
I had a job where I set the atomic clock at an army installation in far south area of Japan. We would listen for the WWVB signal on 10 MHz, which is what these clocks claim to be receiving, not 60 kHz.
We didn’t compare the arrival time of that signal with the clock, pulse put out by our clock, to sync them.
That signal was also broadcast on several other frequencies, including 15 megs 20 megs and I think 7.5 megs.
I really see no reason why you should not be able to receive it in South Korea.
Which really threw me when you said that is where you live.
Wow. I always thought "how can we possibly measure quantum gravity given how weak it is?" But the idea of using high-precision time to measure gravity is kind of mind-blowing.
This would be freaking awesome! Let's do this!
Yes, my friend, you are a nerd. As are we. hence why your content is so welcoming. we all understand each other.
Better get that clock, you might be 2 milliseconds late for that meeting. Rocky & Bullwinkle went to "Tic-Tock-Tech," so they knew what time is or was a guess.
This seems like a pretty big deal! Anything getting us closer to connecting Einsteinian physics with Quantum. Also, the idea of being able to accurately measure the superposition of quantum particles. Kinda crazy. I mean, quantum physics makes almost no sense to me anyway, but sure would be nice to have some of these mysteries cleared up!
I'll complain about that inaccuracy in 35 trillion years when I reach late for the doctor's appointment. This is outrageous!
I feel you dude. You don't want your s.o. to waste money on something stupid and at the end it's frusttrating for both. Next time wish for something or accept whatever and feel happy that you made your s.o. happy. It helps.
Follow up question for Anton, or anyone smart.
Scenario in vid: The Yb atom is successfully placed in a superposition, then it's grabbed by a laser tweezer, then another laser tweezer is positioned near, which then grabs the same Yb atom at another point, because it's acting like a wave, kinda.
If I'm understanding correctly, when the superposition is "broken" both laser tweezers will have a Yb atom in them. The same atom, but now twice. Which is all well and good, but isn't that technically creation of matter? Or is the second atom not permanent? Or are we working with such small increments of time none of this matters cause quantum gonna quantum?
I feel like I'm missing something, maybe when the superposition is broken, there is only one atom again, or something relating to the observer effect?
Or at the end of the experiment there truly are two Yb atoms now and it's similar to how temporary/virtual(?) particles can borrow energy from the vacuum? The experiment itself can't be providing enough energy for creation of a Yb atom, unless it does because it's focused on such a small point, but I don't think this is the case.
What gives?
Breaking the superposition just leaves you with one trapped atom. The experiment would have to be conducted with the superposition intact, carefully measuring the small differences between the two locations without actually determining the 'true' location of the atom.
Great, thanks. That makes much more sense.
Side question, do you happen to know which trapped atom stays and which one disappears? After the superposition is broken. Disappears is the wrong word, but I think you follow what I mean.
If we designate them as Yb1 (the initial atom) and Yb2 (the newly captured superposition "version"), when the super position is broken is Yb1 always the one that remains? Or can Yb1 "leave" and Yb2 remains captured?
Anton, I explain away my gifts too.
Cheers.
I used to tune WWVH station in Hawaii to calibrate 10.000 MHz zero-beat (0.1 Hz accuracy) for my Ham radio (circa 1964).
