"In practice I just want the headphone jack back" 😂
Me too, Sabine. Me too.
Don't use Apple products.
get a sony
I really don't understand the people who argue for the removal of the headphone jack.
The best ear bud is a failure
@@Knowbody42the ear jack increases the cost of cell phones and devices. Wired headsets are cheap, if you buy those. Earbuds and Bluetooth headsets are more expensive by a few dollars.
Get rid of the audio. Jack, and profit!
"An attosecond is one billionth of one billionth of a second. That's shorter than most TikToks." Get 'em, Sabine!
She's serving harsh browns with a side of knowledge today.
No such thing exist, and if it did it could not be detected
Just a shame alot of other physicists serve up bllsht😢@@Bjarne2CTheWorld
@ChecedRodgers I don't know why you invented words while quoting her. "An attosecond is a billionth of a billionth of a second. [...] That's even shorter than TikToks."
@@flandrinelextensionniste6490 Nope, at least you cannot prove that and neither can sabine as no such time period can be isolated. But it makes for good UA-cam ninsense
"Dammit, Sabine!" -Lead author while changing his password
No, no, he’s not going to use it as his password, obviously, he’s going to use it as his vanity plate 🚘
She didn't specify what base he used
Spoken from real life experience, I bet.
Why nobody tried 148.3821(5)nm frequency since 1970s till now?
@@jamesdriscoll_tmp1515 I'm pretty sure that it's base 10. Though the base is always 10 in whatever base you're working in.
Just for some scalar fun - if you were to convert the scale of an Attosecond (10^-18s) to a Second, our seconds would appear to be ~32 billion years long, or over twice the age of our universe. But if that scale seems bizarre, consider that if we were to scale a Planck Second (10^-44s) up to the scale of seconds, a single Attosecond would now take over 3 quintillion years to pass, and a full second would be over 100 tredecillion years long (I had to look that word up...;P)
In other words, the very smallest slices of time that we can currently measure are still nearly endless eternities compared to the smallest units of time that our theories can describe. (10^-44s)
Wow that is the first thing I've heard today and all week. Thank you for sharing
Since 10^-44 is like the pixel by pixel simulation of time in universe, I wonder if how much "precise" we should go to simulate "decent" reality in computers .. I heard someone said 10^-19 would be probably enough to be 99.9% something close to reality, and well good compute wise but damn ..
@@xeqqail3546 I think the issue of representing reality well enough in a computer *to fool a human* would not require anything close to replicating it to that degree, personally. Unless you were trying to re-simulate the big-bang with exact starting conditions or something I guess?
That is mind blowing, just trying to imagine it.
@@Lythif you simulate a world where micro time measurements can't be done yet due to lacking tech, going for let's say micro second time scales would probably already be more than enough. It's about the time it takes for neurons to fire and return to rest.
'thats even less than a tictok' im on the floor
Floor? I love to dance?
Me too :))
Love the non-clickbait headline followed up by sarcastic remarks.
...meanwhile, the add-on "de-arrow" shreds all other clickbait shit for breakfast.
If you want to know what click bait is, ask Scotty Kilmer. Better yet, look at the titles of papers in any Annalen der Physik.
We all wait for this to be implemented in our coffee machines.. the most exact coffee ever !
that weirdly sounds like a step before the food replicator.
"Tea, Earl Grey, hot."
"Your tea will be ready in two point zero eight two times ten to the twentieth power attoseconds."
"I should have never let Data fiddle with the replicators."
Starbucks can more accurately burn its coffee!
I saw some audiophiles consider using atomic clocks to improve digital music. They eventually discovered that atomic clocks are actually worse for this purpose and are only more precise over long periods of time. It made for a pretty good joke that audiophiles can complain about everything no matter how ridiculous.
I too want the headphone jack back
get a ASUS zenfone
@@Isaac_sixhundred I own a little older one. This is an exception not the rule. Samsung even got hid of them in cheaper phones and so on
Headphone jacks are removed so we are forced to use BT or Wifi for our communications with signals allover to spy on us, they can not do it if wired.
I had a discussion today with a flat earther under one of Sabines's videos. He did not accept measurements like this one as "experiments" probably because he did not like the result. I thought how sad it is to have to reject most science progress to defend an undefendable Bronze Era concept.
Very strange. I have a hard time understanding these people.
@@SabineHossenfelderits because you are brainwashed by the illuminati... Or some other bs like that.
In reality all city maps are drawn as if the earth would be flat. Because it is more practical than drawing them more realistically.
Yes, there's so many people these days that think everything they watch and learn is a conspiracy. That must get exhausting and leave them feeling confused and paranoid of everyone. Theres some crazy people about.
@@SabineHossenfelder I think a more pertinent question is, how do you deal with these people? There are many and they're impervious to reason.
Don't forget "JWST just made discovery x that destroys our understanding of modern cosmology."
It's amazing how much quality content Sabine produces! Thank you for sharing your knowledge with us.
The password joke cracked me up🤣
I bet money they saw this and went to change their password.

I feel blessed to have worked with part of the study authors as a student
Lol...idk if you are editing or if you hired somebody but I love the editing.
Your humor really shines through.
Always nice to laugh and learn at the sametime.
Thanks!😂
On NPTEL distance education there was a course called : Attosecond lasers are a big deal
...and they operate at the only useful timescale for measuring movement at atomic scales...which is cool. = )
@@themanagement1535 "...and I thought it was pretty cool"
Thanks!
I was lucky to be able to get to tour the US Naval Observatory in Washington DC in the 90s. They no longer provide those tours to explain how they keep time and allow you to look through their telescope.
I got to see the atomic clocks but I did not get to see the telescopes.
1:16 "Even shorter than..." That is a very good observation!
Sabina, that was one of your best segways to your nord vpn advert. Well done. 😊
Always delighted to watch a new vid from Sabine.
As an Englishman I find this terribly disconcerting. You are German and you are humorous. Now I must question everything.
This is likely the most important breakthrough in particle physics in decades. We need this level of precision to graph collapsed states against time, to determine if there is an underlying cyclic nature, at time resolutions currently inaccessible to us, to what is currently popularly termed superposition.
Sabine is a celebrity now. Today was a large article about here in Germany's daily newspaper Süddeutsche Zeitung.
She is awesome man, she is literally my main authority on so many things. If she said something, I believe it 😂
@@adnan4688 Automatically believing anyone is risky
@@adnan4688nothing wrong with admiring someone but you should have a level of scrutiny with everything
not saying she's wrong or anything just saying that in general
@@DeusExtra You guys really lack some social skills. I am not being literal, this is to be taken with a grain of salt. It's more of a compliment. On the other hand, I do understand that there are dumb kids on the internet. I may have said the same thing you told me to someone else...
Thank you for the video.
You can probably tell from my username that I am particularly excited about this one
Excellent offering as always, thank you! 😊
The way you express your subject matter is beautiful and precise.❤❤
Fascinating! Thanks, Sabine! 😊
Stay safe there with your family! 🖖😊
So harmonic! Much wow....
Wiggle wiggle wiggle
Fascinating and humorous, great combination! Keep up the great work team👍 The first gas laser I bought was a 1 mW, and cost £600, (1980s) Semiconductor equivalents are almost given a way free in cornflake packets now.
Let me guess, the wavelength was 632.8 nm. Fixed by atomic precision. Excellent beam quality, Today's laser diodes, hm, some arbitrary frequency and poor bandwidth parameters, strange beam shapes; they are pimped LEDs.
@@georgkrahl56 Spot on! He-Ne laser 632.8 nm as you say excellent beam quality. Used it sometimes for somewhat less scientific purposes. Front silver mirror attached to a motor, made some nice swirly patterns.
The graphic shown at 2:32 is next level great in many different ways. Thanks!
Really interesting. Good to see progress.
Thanks Sabine. ❤
I remember last year's Nobel price, very hyped about that.
Tomorrow morning I will apply for a patent for the world's best egg timer!
It is clear that this format of scientific information cannot meet the standards of a respectable scientist. The humor or irony with which Sabine masks this can also be seen as her method of conveying information in a UA-cam-appropriate manner. I am a math and physics teacher and I sell my content so far reduced didactically that structure often gets lost or becomes indiscernible. However, I see this as a benefit for my students, as this information would otherwise not reach them, or they would hardly retain it. I would now like to sincerely thank Sabine for providing this didactic reduction for me as the recipient of the information. It's enjoyable to watch Sabine! I hope the scientific community sees it that way too, at least in the field of science journalism. So, thanks again to Sabine!
Thank you for feeding my need for obscure (and not so obscure) but always interesting random science info, Sabine!
Imagine, … headphones that do NOT require charging or blue-tooth pairing. WOW!
The attosecond clocks are not attoseconds but measure 250 attosecond blocks from the article.
Phenomenal video, your channel is truly underrated and should be a staple in highschool science courses everywhere.
Awesome! Go Sabina, go!
PSA: A VPN does nothing to prevent hackers getting your credit card information.
But it does hide your IP and you can change your location, so I'll be using them for that instead
Well, not nothing, but very little. Info is already encrypted while in transit (hence “secured”). The problem is once it’s decrypted and then stored with often zero encryption on websites that are often poorly maintained. Never store your credit card info on websites or in browsers.
No, not if you fall for a phishing scam…
It might in some rare cases. Though, the vast majority of "hacked" credit cards come from database breaches.

This will allow scientists to control the resonance of nuclear spin more precisely, especially in the Bose-Einstein Condensate states, leading to modified vacuum energies (and time-flow) in the nuclei proximity and the generation of anti-gravitational fields.
Hahaha great humor as always
A wizard still arrives precisely when he means to.
love ya news vids Sabine... the mix of comedy and science works great!.... dont stop doing what ya doing!
Thorium seems to be the go to element for just about everything these days!
Reminds me of the atomic nucleus of the beryllium isotope, Dr. Hossi recently reported. It was dumbbell-shaped, wouldnt that give a good resonance?
I wish your videos could be longer again and with less ads and still be profitable enough to continue with this
the ads are now about 1/3 of the video. 😑
First seriously members video! Feel thrilled 🎉
Welcome!
Damn you, Sabine!! (.......... I love Sabine so much!)
Yes, I agree, Sabine, Sabine.
Sabine, complements to your writers. The quips keep getting better and better!
Slow down. I'm still awed by the magic that is an EUV stepper.
"10 to -18 of seconds. For context, that's even shorter than tic-tocks" - hahaha, you nailed it :D. Sabine, you need to write a script for a science comedy series. Finally, we would have funny, comedy...
Always enjoyable! Also I actually learned something
Hossi out with another excellent episode.
Your explanation of how scientific progress builds on what came before, and then allows for further research to build on it, is an important one. Certainly, as you said, it doesn't always work that way. However, it's an important summary of why incremental progress is so important.
What I find most astonishing about this as a physicist, is the philosofical implication of this result. Nature takes its laws very serious. There is a universal mathematical precision underlying everything. We don’t know yet how far it goes, but this precision already blows my mind.
Nice !
I am a poorly educated layman and although a lot of stuff is just beyond me I just love your channel, I see and learn things I would not have known even existed and you show it all with a great sense of humour. Thanks a lot.
You can find overlap, but x-ray can excite inner layer electrons, and gamma can excite the nuclei.
In practice these categories are created based on the typical process that produces them.
I did some software work a few years back on PTP (IEEE 1588). At that time I did extra-curricular reading on the history of time keeping, various time standards, etc. Great stuff. Increasingly accurate time measurement is a keystone tech.
There's another coincidence - 1 second per 300 million years & 300 million m/s speed of light
1 billionth of billionth. Thats insane that can be calculated let alone applicated.
It would suck to loose count and have to start over agian.
That would be a true nuclear clock then wouldn't it..
This is really cool.
Frequency Frequency Frequency.
Leading us towards Tesla's ideas.
Still ahead of his time.
We are learning more and more how much Frequency matters.
This is an amazing step.
Love ❤️ your humorous presentation Sabine
I love your wit.
So we face the possibility that our next watch will need to adjust its time to take into account GR.
Photons might work.
The click bait headlines are gold.
Great overview as always!
One thing that is really fascinating for me is the possibility in principle to make so accurate clocks which translate to extremely precise and accurate frequency measurements which translate to very precise velocity measurements. Which may allow us to start measuring the expansion rate of Universe almost in real time. Well, with a little help from E-ELT telescope. 🙂
As they said in the 1950's, "You can't stop progress". As we go up the chart, things get quicker.
I too desire 3.5mm, Bluetooth headphones die.
Very clever
Thanks for making that electromagnetic spectrum graph available. Hope you don't get into any copyright issues for that...
@3:40 That frequency works out to be 2020.408 THz, which compared to the 0.009 THz of Cs clocks gives you an idea of how much faster that clock rate is, and thus how fine the precision will be. This is amazing news! (and not clickbait at all)
It really puts into perspective just how incredibly fast and small things can be. To give you an idea, an attosecond is to a second as a second is to roughly 31.71 billion years-about twice the age of the universe!
Very cool.
This was really good, one of your best. I don't know how long it takes you to come up with these cleverly witty scripts but they are very enjoyable. "I just want my earphone jack back"

It's not the atomic clock that made this "precision" for synchronisation of all the world's clocks.. It's because there is now only one clock that dictates all the other ones in the wolrd. It's called the UTC.
Universisal Time Clock
UTC is based on TAI, which is based on the readings of around 600 aomic clocks around the globe.
I almost believed that the video was going to be about clickbait
The importance of atomic clock precision in making GPS functional and precise is hugely important. It's a great way to illustrate why these esoteric-sounding advancements are actually worth understanding (and funding)!
Fascinating!!!! 👍⏰
I'll never forget this lesson! How 3 men over time, split 🪓 the atomic nature of time into a Noble prize. How Sabine may someday get the same for explaining it so elegantly, on UA-cam!
i remembered last years nobel prize was for attoseconds.
Lol. Nucleus wiggled. That sounds cute. Love it.
The first caesium atomic clock was invented by Louis Essen in 1955. Physicists have only had nearly 70 years to develop a better more stable clock. These news stories keep on appearing about the immanent appearance of a better more stable and precise technology to replace the practical tried and tested Essen Atomic clock. I suppose one day the story might come true.
its one of those 'sell arguments' for why the research is important or has applications. You need to sew many seeds to reap the technological benefits
Lead author: "Damn it Sabine!" _Hurries off to change password_
I think it would be really interesting to continue this conversation and showcase science which didn't at all achieve its objectives but progressed our understanding of some thought to be separate subject areas
😂😂😂😂😂 you're so smart and funny Sabine thank you so much for making the science I've loved my whole life so easy to digest and pay attention to. You're an amazing science communicator.
"I just want the headphone jack back" - me too! What on earth possessed _everyone_ to get rid of this vital feature?
Apple did it because a headphone jack on a phone is a place where dirt and water can enter the case, so it's impossible to seal against contamination. Also, the jack can wear out and become unreliable fairly quickly.
Everyone else did it because Apple did it.
Apple purchased Beats by Dre in 2014. They removed the headphone jack in 2016. Not sure why Samsung followed. I currently use a Sony, which has its own issues, but still has the headphone jack.
@@daveh7720 > It's impossible
Based on what exactly? It's astounding how I can envision solutions to that without much effort. That's simply their contrived excuse. Really, it's about extracting a bit more profit by taking away features.
Oh, and what about the main socket that the phones have? Why are the mentioned problems solvable for those but not a simple HP jack?
I just want the charging jack back. USB is primarily for data and using it continually for charging just wears it out quickly. It's just built in obsolescence to get you to purchase another phone.
@@daveh7720 And a tiny rubber plug would add 0.001 cent to the cost of each unit, while the removal of the headphone jack would save 3 cents from each _and_ you are forced to buy a compatible bluetooth device that they will happily sell you at an unnecessarily high price.
If you ever wonder why a corporation does anything at all, the answer is _always_ money. Every corporation is an amoral sociopath only just barely, but not always, held in check by the threat of taking money away from them.
Thanks Sabine, groundbreaking? I will buy this one. Àlso like the idea it is another use for my favourite element
Semiconductors use UV, Deep UV, and some X-Rays to cut paths in photoresist (harden/soften, wash the soft, deposit metal traces, wash the hardened resist off, repeat thousands of times per wafer of chips). They are big honkin machines, maybe the size of one of those eco cars (glorified golf carts), maybe as big as sedan sized, and that's the compact form. You maybe can put one on a trailer and haul it around like a Howitzer, shooting at whatever you want, maybe Dandelions, fish for supper, or unruly asteroids.
Things already seem very precise. What kind of applications can we do now that we couldn’t do before ?
If you keep thinking you'll just watch more and more of Sabine's videos until you understand physics, i it'll never happen, but you'll keep watching.
Me too miss the headphone jack a lot

Excellence in motion. I bet you have a Nobel coming Sabine. One of life's most meritorious if you ask me.
all this wonderful progress. you see all the good things that science has given to the world.
I want the headphone jack back too!
I'm a programmer, Sabine. A technical improvement that will probably only have practical benefits in specialized contexts is just about the only thing I do get excited about
