Inside The Most Precise Atomic Clock in the World
HTML-код
- Опубликовано: 24 авг 2024
- From his basement lab in Boulder, Colorado, physicist Jun Ye and his team have built the world’s most precise atomic clock. The clock is so powerful it can measure otherwise imperceptible changes in the physical world. “Have you ever seen the movie called Interstellar? You’ll see some of that in our lab, it’s not science fiction. You can actually see clocks slow down,” explains Ye.
In episode seven of The Most Unknown, geobiologist Victoria Orphan travels to JILA-a physics institute jointly operated by the University of Colorado Boulder and NIST-to untangle questions of space and time with Ye and his otherworldly atomic clock.

"...Over the entire age of the universe, (this clock) will lose less than one second of time." This is in comprehensively accurate!
the universe is infinite and has always been. that will change before the universe does. our current distance is the pictures of 14 billion light years away. you could still see more if your tech was better.
@@EnergyTREyour? Are you a alien
@@Tovogaming feels that way most the time.
@@EnergyTRE is that because I have no idea what you’re saying
@@TheGuyWhoComments that's because you assume everything. never really understanding or comprehending just regurgitating information said to be correct.
”Have you seen interstellar?”
”No”
Proceeds to spoil the whole movie
who gives a fuk its old
And over dramatic sentimental nonsense about some dude stuck in a wall
@Gla ZeD and Z-Dog: If that's all you got from the movie, perhaps you should talk with some actual astrophysicists and ask them why they all like "Interstellar" so much.

Is there a video where Ye goes more in depth about this clock?

The whole thing but 16:48 specifically.

@@Dutchalchemists Thank you.
Losing less than one second over the age of the universe is mind-boggling. Just think about that.
I HAD to subscribe. This channel covers some really cool stuff.
Thank you.
This video is way to short for a complex subject like this!

It took this company over 50 credited people to make this short video, in which one guy speaks and another is there for... I have no idea why she's there. And then there were a few shots of the device itself, and then a few simple animations. But this company apparently needed over 50 peoples' work contribution to make this film. I have no idea how they can stay in business with that kind of a model, but for sure at that rate a longer, more in-depth video is out of the question!
Most satisfying thing is..this video is released on Oct 4 but it is still oct3 here in india
If you had a ladder you could poop in the street faster
Still not as precise as my dogs internal clock, she always reminds me when to feed her. Great video!
pff, its not hard to be hungry 24/7
Dad joke 101
Lol I get reminded everyday no exceptions 😂
Huge shoutout to the people that draw and animate things smart people say so numb nuts like me have a chance of understanding it. You're the real MVPs!
So cool to see Ion gauges and vacuum chambers at use in other fields. I am 20 and I work in semiconductor industry. I never knew quantum clocked used hi-vacuum as a part of their processing. Awesome video, thanks you guys
nearly every field in experimental physics needs high-vacuum and mostly ultra-vacuum , what are you talking about , and all branches of E-P needs Vacuum equipment
semiconductors are gonna be the silicon chips made on the wafers that are supercooled into the BEK state of matter. Still taking advantage of superposition, extra-dimensions and the magic of the void... technology that finally breaks it's working beyond time itself. It's really impressive!
i'm glad they have improved the accuracy of the atomic clocks .from losing a second every 100 million years to losing a second every 200 million years .
its means we dont have to reset our watches as often
Time dilation is when time moves faster for your girlfriend and time moves slower for you at the shopping mall.
This is the single best production I've ever seen on youtube.
that soundtrack, though
Name please?! I need it for programming :D
Sorry, guys. I would also love to know
i was scratching my head when i saw this comment at the start of the video. i agree, it actually blew me away. it matched the narration quite nicely.
It's called Don't you worry by ILL-Esha
thanks a lot
About time you released this video @motherboard. (Pun intended)
"The echo of Big Ben coming back from the edge of the universe". Now THAT is very sensitive measurement!
Amazing video, as always!
Absolutely love this channel.
What does picture read at 1:10, with the caption I LIED?
"Remember when I gave you an important hint on your paper?"
*very safety. wow.*
Thank you Dr Ye for this amazing work.
That pendulum effect inside those atoms are something really impressive to thing about😁
The way he corrected time speeds up to time slows down 3:09 🥹

You guys should make this a minidocu, that science is connected. Really cool how the previews person is in the new episode.
Who came up with this idea needs a pay check raise :D
This is part of a full-length documentary we made that's available on Netflix! It's called "The Most Unknown" and is available now. The full length is different than these shorter episodes, so we think both are worth a watch. If you watch it let us know what you think :)
Very *important tool for science !*
Personal clocks can be as wrong as we want. Science needs very correct clocks.
Such clocks can help with many experiments, where time is a critical factor in the math.

Why a Strontium Atom and not a Cesium Atom? What considerations go into choosing what atom will be use to make an Atomic Clock?
higher energy state is more accurate
my Casio Lineage watch is the most accurate - it is solar powered and at 2 am in the morning it talks to the atomic clock in Colorado and gets calibrated to the exact atomic time. I calibrate all my other watches and clocks to it. Such a great watch and I can wear it on my wrist.
"There is no clock...in the world... no clock...keeping time..." and now the song about time is in my head :D
I will be the first in the comment to say Thank You to this guy for the important work that he is doing :)
His contributions to humanity are truly immense.
I never thought about using a clock/time as a way to measure mass.
time is a... let's say... an entire spatial dimension by itself just like the other 3 mathematically predicted. That's what Einstein meant by his General Relativity formulas that derived from Lorentz formulas.
But time is also considered an important factor on thermodynamics as well.
So the pendulum is basically just the strontium atom cluster?
I love this man concept. Wow mind blowing man👌👌👍
3:11 ME when I am trying to pretend that I am surprised and excited about something BUT I AM ACTUALLY NOT ;p
Are atomic clocks affected by gravitational waves?
Yes, but current atomic clocks are not that accurate, and frequency shift due to gravitational waves is masked by the noise in the local oscillator (laser used to probe the ultranarrow atomic transition). In the near future, it is possible to increase the clock accuracy by several orders of magnitude and atomic clocks might be able to detect gravitational waves.
Thanks for the video. I was pretty doubtful of this topic, expecting that they've found a new element that can vibrate better than the previous record of Hydrogen. I also doubted the statement at 2:27 as it cant easily the most accurate measurement ever. I thought, if scientists will be able to count the vibrations or cycle of light, then it will be insanely accurate (considering that the distance traveled by light in KM was adjusted to remove the last decimal, basing the length of a meter from light. The unit of meter and second are intertwined) .
I got ahead of the video when I searched for the basis of measurement of the second in wikipedia, then the words, Optical Lattice blew up to my face. They finally did it and was announced in 2015!
It is intriguing when he mentioned it could be used for gravitational waves. I imagine them building one clock at the bottom of a building and the other at the top. The two clocks will know each others rate all the time, when a gravitational wave arrives, the clocks will detect an anomaly.
Where are the new generation of American students studying science? OOH I forgot school tuition is $25,000 a year.
While I am not happy about tuition, I am proud that this research comes out of an American university.
Amazing!!
About interstellar... The body deterioration and the body aging process will not slow down even if time shortened or not.
Is this the guy who played in "The Goonies"
Data? lol

If you spent too much with atomic clock I end up with blue balls
Thanks for new information
The song at 2:23 sounds like the music that plays in Paper Mario The Thousand Year Door, in the pit of 100 trials.
Lol no doubt

Nice job ending up as a podium for this Jun Ye guy, Motherboard! To be fair, seeing his office at 1:11, the guy could use some new furniture anyway.
This is great content, thankyou

What exactly holds the strontium atoms suspended? Is there some sort of laser or something?

Marvellous
*mindblown*
Dr. Orphan got the YEEKS.
Interesting, so what force is causing time to speed up if you raise you watch up a few center meters? 3:06
Gravity.
curvature of "spacetime" "event" caused by gravity
Since dark matter has only been detected by gravity then perhaps there is more to gravity than we know maybe there is no dark matter but a undiscovered property of spacetime perhaps there are two space times in sinc with one another we know that the majority of "dark matter" appears on the outskirts of galaxys allowing for rotation to be rather uniform when we know due to relativity the rotation should decay that's why we blame it on dark matter an invisible undetectable state of matter affecting gravity in the absence of regular matter what if rather than there being a dark matter instead a new characteristic of spacetime why is it that dark matter is concentrated on the outskirts of galaxys perhaps when you get further away from the center of relativity the phenomenon of dark matter will start to appear perhaps it's a shift between the fabric of space if there were two space times they would act on each other in unknown ways and perhaps that is what we are seeing when you get further away from the center of relativity the weak weak forces of gravity separate into two and may cause a attraction effect between the two appearing as if there should be mass in such areas when any matter is undetectable maybe the law of gravity works like a particle and if this is the case there may be still much to learn about relativity adding to spacetime being so fundamental this could open up a whole new branch of physics interactions between spacetime.
Explain space time
@chibikong hahahahahahahahahahahhahahahaha
@chibikong Every English teacher in the world got chills when the op posted that comment.
great stuff.
nice to know
I think Einstein had it wrong and that time is constant, not the speed of light. I think dark matter density is the limiting factor to the speed of light and that gravity and dark matter density bend/pull on light (and everything else), not 'spacetime'. I think quartz pulses and atomic clocks are induced to operate more slowly when traveling at high velocities in space, slowing our measurements of time, not time itself.
A million billion????
NEED THAT MUSIC! @Motherboard please publish the tracks used here :D
So yes, time can be slown down. Thanks
But can it wake me up before 8 am classes??
*For me, even an earthquake can't wake me at that time*
It's almost as precise as a chihuahua's tail.
Not very portable though. I don't think I be putting one on my wrist anytime soon.
Ok so how to make this defeat stealth platforms hmmm? Mass detection and quantum entanglement would be pretty amazing.
Music....Space... TIME
What's going on? How does this company's finances work? You've just credited over 50 people for the making of this very simple, two person and one object film. How does that work?
Attempting to building most accurate quantum atomic clock... Uses a rigol oscilloscope
What is wrong with that instrument? Bad quality?
Why not Livestream the atomic clock. ?
RUclips dollars..
The delay introduced by the live stream would negate the precision of the clock. Although if that wasn't the case your idea would be great. Super precise time just a click away!
Yeah. It's been done. Your pc and phone use it and already account for the latency problem.
en.m.wikipedia.org/wiki/Network_Time_Protocol
Or you can buy a clock that gets an atomic time broadcast, those have been around for decades.

RUclips Customer Support Turns out we're both wrong. I have two phones so I brought up one on LTE and the other on wifi and checked. My LTE time was just over 600 ms off from network time, but wifi was off by 2 full seconds - so that's service-dependent and NOT incorporating NTP time correction.
My Linux machines are under 400 ms jitter, I'll have to check my Windows and Macs.
Good catch!
Still - NTP apps can be downloaded, GPS status can as well, there's no need to livestream a stratum 0 clock to watch for entertainment.
PS - let's be agree to be careful about the definition of perfect because nothing is -
serverfault.com/questions/508586/is-there-research-material-on-ntp-accuracy-available
RUclips Customer Support Fwiw, I just checked my Windows laptop - less than a second error, same wifi network as earlier when I checked my other phone.
So... what object is at various different times at the same place when not being observed??
So this video seems to indicate (although it doesn't say directly) that an optical lattice atomic clock is even more accurate than the F2 Fountain Cesium atomic clock which has been the world's most accurate atomic clock since the F2 Fountain Cesium atomic clock superseded the F1 atomic clock in terms of timekeeping accuracy!
Awesome
Drinking game; everytime he says quantum take a drink.
Time..... IT'S THERE,it's not there.
Star treks transporter would need something like this to freeze time to a quantum level for a scan and construct, But it would have to be a wee bit smaller as it would only be one critical component.
The warp drive is reachable apparently easily using electricity on nanocarbon tubes... mini warp drives were discovered in a NASA experiment recently.
Boulder!!
"Time" is a human measurement.
"Time is a human construct, and you were below the waves."
From "Stormbending" by Devin Townsend Project. Good tune, check it out.
He has the most precise atomic clock in the world and im stuck here today trying to get our cisco switch to ntp sync with the time server......sigh
If time changes , if it really is relative, why do we need to measure it with such precision. why are we aiming for most accurate time measurements?
very safety. wow
He took my jerrrbb!!
I dont understand, shes supposed to work in Caltech but looks in awe when hes explaining her about time dilation?
Didn't it say she was a biologist?
It’s a fascinating subject. Even though I’ve heard it and researched it many times I always like to hear discussions about it.
Time is an illusion.
So might suspended in midair by nothing else? Lightsaber possible?
The first few seconds were so catty
Oh yeah yeah
..Note that a real natural Earth day has +- 15 nano second fault margin daily...it does not complete a day at a same point
If that precise clock only measures time in a very specific location, the only true way for it to be completely useful to society is to have thousands or millions of these clocks communicate to each other only to provide more information on distance than actual precise time. I don't see that kind of clock fitting in the dash of your average hatchback.
Why does this does not have a spoiler flare?
So does it use an LCD screen or analog hands?
You didn’t explain how it works. More science and less fluff please.
precis :O)
How do u set the alarm on it? All i wanted to know
2:25
my iphone is gospel for what time it is. period.
I wonder how much longer until that fits on a wrist.
more drama ....less science. Please explain next time how they did it and why is it important
They did explain why it is important lol Watch the video first
More drama? You cannot be serious!!
It's very important for GPS tracking. Since satellites are so far above the Earth's surface (at least geostationary one's) that relativity comes into play and can change the time of clock onboard the satellite and on Earth. They need atomic clocks to counter that. The time needs to be so precise for tracking that even an extremely small fraction of second can mislocate your exact location by few kilometers.
yeah I'm unsubbing. This just makes science laughable.
I know right? I wanted to know more specifics about how it works and what experiments it's specifically being used for.
....From your roommate back in BOULDER.......
He will win nobel prize.
Thinking about quantum time I thought about the sun dial and how it was timing space then realized the core is connected to space first before the top side so we have to record core time tempature to load with atmosphere time pressure temperature to match the load sound of void time to accurately get the quantum time structure the core know the sun time so it knows when to start the day with pressure light activity or Cosmic energy like timing atoms to there kinetic structure body hold of why is the form in this time motion
