How Do Atomic Clocks Work?

[@jimmypk1353]

Steve Mould sent me here :-)

[@adithyakaravadi8170]

The best explanation I've found so far. Also very accurate, most other sources are not. They say they "9,192,631,770 vibrations of Caesium atoms" which is incorrect and very confusing. It is "9,192,631,770 oscillations of the radiation that excites caesium atoms". Thanks for this!

[@DomBurgess]

Fantastic! So glad you liked it, and glad my info was accurate. Thanks for watching! Dom

[@williamg9695]

You deserve more subscribers based on your content and work

[@DomBurgess]

Thank you! I agree! ;)

[@DomBurgess]

Thanks. I use a NTG4+ and place it as close as possible, a mixture of above and below frame. I'm not sure why my audio still doesn't sound great. My house has a lot of hard surfaces though which is the only thing I can think of.

[@abhisekbhattacharjee9503]

Sent here by Steve Mould... You're good, man! Loved your presentation!

[@FeRoOOo71]

dude, where are your subs? your shit is on the same level as Vsause, keep up the good work

[@DomBurgess]

Thanks FeRo00o71! That is a huge compliment, I'm a big fan of Vsauce. Its tough starting out as a new channel and I don't do much promotion at the moment, need to do more for sure. Every subscriber helps though so please share with your friends! Thanks for the support! Dom

I have an exam on atomic and molecular physics coming on and today I was reading the notes of the professor. But when I saw that next topic was on atomic clocks I just thought: let me KZbin that to gain some motivation. You gave me the motivation to continue reading and not to be lazy, thanks!

[@DomBurgess]

Amazing! Thanks Smalde! Thats what I love about KZbin, you can learn things in so many different ways. :)

[@berkk1993]

wow, what do you study?

[@JanosZakarias]

Excellent video! But something's not clear: how do the convert the oscillation of the quartz crystal (32,768Hz) to the frequency of the cesium atom's resonance frequency (9,192,631,770Hz) in the radio wave transmitter? At 4:02 you say the transmitter will transmit at 32kHz, but to 'excite' the cesium atoms the frequency needs to be it's resonance frequency (what you show at 4:33). Is there a missing step?

[@Sebastian48532]

Haha where are the subs man? Honestly one of the best KZbinrs.

[@DomBurgess]

Thanks so much Sebastian! I honestly don't know, I think it's because I don't post regular content - life gets in the way! I am trying to do more though. Look out for a new video later this month. :)

[@DomBurgess]

Thank you! :)

[@rahulshah7578]

Dude. Your content is amazing. Im very happy Steve sent me here. Keep up the good work, we all appreciate you

[@ViralKiller]

wouldn't there be a small error that accumulates everytime the cessium corrects the radio waves?

[@hassanm.1887]

Who else comes from Steve Mould?

[@jackasotarex]

Sir, this is probably the most well spoken and thought out demonstration of everything this Earth needs...Please, never stop. You are fantastic. I am metaphysically setting us up to meet one day. Take care!

[@Jaiysful]

Holy crap, this content is amazing. Insane amount of work going into the editing and animation. Subbed! Hope your channel keeps on growing!

[@rafaeldiaz847]

I really hope you get more subscribers. Your content is amazing. Great Job!!

[@DomBurgess]

Thanks Rafeal, me too!

[@Adam-od2ij]

I have been unable to grasp this concept for days, until this video made everything click! Thank you!

[@madhavdua8624]

Don't listen to hater dude do what you like. People keep complaining even when they are watching everything for free.

[@AlpacaZ]

There's something I don't understand 100% here. The fact that Caesium resonates at that frequency and that frequency is exactly 1 second blows my mind. I understand that that frequency was defined to be a second but, when they decided to make that specific frequency a second, they used their previous definition of a second to come up with that number, correct?... I'm just wondering... Did they come up with that number AND by coincidence it was also the resonant frequency of Caesium, or did they have a close number and decided to round it to the Caesium's resonant frequency?

[@baredesigns1]

Me too. Came via Steve Mould

[@nithikasandinu9034]

Where are the subs man; You must have at least 1M subs; Upload content every 2 weeks; You can hit 1M within one year.

[@DomBurgess]

Children and full time job doesn't really allow me to do that unfortunately! :)

[@qwerty83484]

subscriber count do not all reflect the quality of the video.

[@DomBurgess]

I agree! Thanks for watching! Dom

[@albertnisbet2578]

Great concise video, thanks. A minor correction, though: GPS satellites don't determine your position, they basically just broadcast their time. The position is calculated by the receiving device.

[@unfa00]

I'm glad Steve Mould gave you a shout-out!

[@Thark]

These videos are amazing! I freaking love them! Do not stop making them please, I can't survive without them now D:

[@DomBurgess]

Ha ha! Thanks Thark, thats really kind of you! I am trying to post more regular content - look out for a new video at the end of this month. :)

[@aarushgadge8015]

Thank u sir for explaining in easy way , We need more people like u in WORLD , #LOVE FROM INDIA

[@DomBurgess]

Thank you too for your comment, made my day! :)

[@dinosanchez8528]

You speak at the perfect speed for me, others tend to go a little fast. Great video, thanks!

[@NSLikeableHuman]

Here from Steve Mould’s quartz video. Absolutely clear explanation in a well-produced video. I’m astounded you only have 20K subscribers (as of writing), but you just got one more. :D

[@ThomasKrKr]

criminally underrated channel. YT recommendations, do your thing.

[@robertreitze3192]

Hi, can you tell me where you got that wool pullover? I've been searching for just such a thing. Also the video was excellent, especially in that it sparked my interest and I had to get a deeper understanding, as you can't cover all detail in a 5 minute video. I'm here from Steve Mould's video on Quartz Clocks. You deserve more subs.

[@rock3tcatU233]

The clearest explanation I've seen to date.

[@anchorbait6662]

Got recommend to come to this channel. Definitely earned my subscription. Good work

[@telkakaston1657]

Steve Mould sent me here and told me to SUBSCRIBE. I like what I'm seeing, hearing and learning from you, so you've gained a new subscriber. Be sure to thank Steve for the shout out, Dom!

[@karpios34]

what a great channel, hope it blows up

[@PhiTheProducer]

Holy carp!! Two Everythink episodes in such quick succession? You spoil us, sir.

[@VivekTR]

Excellent video. Leaving a comment to please the KZbin algorithm.

[@ritvikvaishnav3472]

Steve Mould brought me here. I was sceptical at first, but your quality blew my mind. Liked and subbed. Keep up the good work my man

[@Henrque123]

Steve Mould sent me here. This channel needs to be known, it's really good!

[@peterandersson3812]

I came here from a link in Steve Mould’s video about quartz clocks. And now I’m a subscriber. :-)

[@miroslavhalza6289]

The frequency related to the electrons is millions times higher than the frequency of the whole atom-atomic clock. For the example, the transition frequency of the electron in the hydrogen atom is 2.466 PHz. But the bouncing of the hydrogen atom is 1.42 GHz. You made good visualisation of the orbiting electron. But you must not forsake that the electron moves in the magnetic field of a nucleus--positive charge, and so, torque from the perpendicular direction acts onto the moving charges. The result is that the axis of rotation for the electron, whether for electron-nucleus also turns. Namely, the nucleus is orbiting also. When we have just one negative charge-electron and one positive charge-nucleus, then both rotate around the centre of mass of the atom.That is why both moving charges (electric currents) induce magnetism. And then, each charge moves in the magnetic field of other charge. Therefore, there exist the precession, and its frequency is over millions times smaller than the frequency (revolutions) of the electron. And this frequency is the working frequency of the atomic clock since the atoms move as a whole due to this precession. Think about it and try to make a video that contains a whole truth about atoms. Thanks!

[@apoorvpotnis]

Steve Mould sent me here. You definitely deserve move subscribers. Great content.

[@jortand]

Got here from Steve Mould, great explanation on the workings of an Atomic Clock!

[@nottherightone2]

Holly shit the animations and work put into this is crazy, great channel!

[@johnmclaughlin4778]

I feel like I just stumbled into the first 1% of subs to a big channel. Well done and keep it up sir.

Thank you, Ander Herrera

[@LordDyfanDaviesMBE]

Do miniature atomic clocks work in the same way or are they slightly different?

[@DomBurgess]

They do indeed.Thanks for watching! Dom

[@thec-m]

Here from Steve Mould’s video (from May). Instant sub.

[@blank001]

Great video. Perfect mixture of explanation and humour.

[@deepfake4718]

Best explaination...Keep going.... subscribed you channel

[@anneeq008]

That finishing fact though 😮🤯

[@Pixelon_]

Steve Mould sent me to this video. Surprised to see you have not even 10K subs with such high qual content. ~Keep up the good work.

[@Bbeaucha88]

How on earth are you not at 1mil subs?!? Your stuff is top shelf KZbin!

[@TheDarkzHD]

Got my subscription for an easy to follow and fun informative video on not such an easy topic! Thanks for the video pal!

[@DomBurgess]

Thanks! Glad it was useful and you enjoyed it! Dom

[@paulcosby8662]

Nice video. Came from Steve Mould's video on quartz clocks.

[@dt9327]

Why I dont know about this channel, very cool work. Thank you

[@alfredpetersbourg3324]

Thank you very much bro really well explained nice animation in there everything is slick

[@nineballking06351]

Thank you Steve Mould for a great recommendation.

[@Maisonier]

I'm here because Steve Mould, amazing video! subscribed.

[@amfalek]

You, sir, have earned a new subscriber. Every second of your video was informative and entertaining. Awesome topic too. I'm ready to dive into your other videos.

[@DomBurgess]

Thanks so much! :)

[@ericsbuds]

holy smokes! that last atomic clock you mentioned is nuts! less than a second off if it ran since the big bang jeez.

[@shayanahmad5439]

Came here because of Steve Mould. Subscribed right away! Amazing presentation buddy!

[@TheDIYScienceGuy]

Very well explained! Thanks so much! Awesome channel! 🤯

[@thomasgale96]

beautiful video thank you

[@johnfrancisdoe1563]

Lots of small mistakes in this video. GPS doesn't work as you say, although parts of Galileo might. Cs-133 has more than one frequency in that range, so the clock has to check if it hit the right one. Also, the Cs-133 can't be vibrated all the time, so they they turn it off for a bit while keeping the tuned quarts running. Oh and while the NIST click may run incredibly close to the speed in the spec, that speed is slightly wrong, which is why we need leap seconds every few years to make it actually right.

[@thunderbird252]

Steve Mould sent me! So based on that, and the first 47 seconds, you've earned a new subscriber!

[@cavinrauch]

What an amazing video ! I've always wanted to know how 1s was defined !

[@rodmcnew]

This is the best explanation i found.

[@mileycyrus9730]

The real question is if there was no reliable source that expressed 1 Sec how did scientists know that 9 192 631 770 oscillations of a caesium atom is equal to 1 Sec??? Plz answer

[@Selas81]

Steve Mould sent me here and now I've subbed, thanks for the video from Denmark!

[@edbeltran3805]

Great video! really informative and simple enough for me to follow. keep up the good work!!

[@DomBurgess]

+Ed Beltran Thanks Ed! Much appreciated, and thats exactly what I aim for - simple but informative. Thanks! Dom

[@squidcaps4308]

You got a sub just from the intro alone.

[@denwahwoo]

I'm here from Steve mould and I'm a new subscriber! Great vids!

[@davidfally5449]

So.. that mechanism is a bit like the new brain stimulators for Parkinson patients

[@drewlyton]

Holy crap! The motion graphics!!! Great work!

[@RmnceKng]

What an excellent video filled with succinct information, great animations, and just the right amount of humour! Thoroughly entertaining. Especially the unexpected opera singing animation! aha. Keep it up, subbed, and "belled".

[@chikoo7584]

what do you think , if an atomic clock started just from the big bang then what would be the time difference between todays clocks and that clock, 7secs ? 2 secs?

[@josephw7070]

Great job keep it up, only 3 videos and I am already booked on this channel, by the way do you take video content suggestions?

[@DomBurgess]

+Joseph W Thanks for your support Joseph! Very kind indeed! Yep, I do take suggestions, please let me know what you'd like to see. Thanks! Dom

[@josephw7070]

Awesome thanks, how about SpaceX (commercial rocket company) and their plans to send people to Mars for $500,000.

[@DomBurgess]

+Joseph W Thanks for the suggestion, there will definitely be an Elon Musk related video on the way. Watch this 'space'!

[@hettiem-c1229]

I'm 12 and I understood this video Very helpful and well explained

[@pixels303at-odysee9]

Subscribed. Simple but accurate video explaining in a way everyone understands. Been many years since taking Digital fundamentals, flip flood being one of them. Time for a refresher to relearn what I forgot.

[@bobjohnthemonkeyman]

Came here via Steve Mould, nice video!

[@antoniomonteiro1203]

Just a small clarification: Hertz (abbreviated as Hz) is the frequency unit, not only for radio signals but for anything that oscillates.

[@HACKINGMADEFUN]

Steve Mould sent me here. Awesome video.

[@DirtyPoul]

I came here from Steve Mould. Great video, you got yourself a new subscriber :)

[@GoogleUser-gv2tq]

Steve Mould brought me here. Great video! Subscribed :) Keep up the good work!

[@ReedHarston]

How many people here from Steve Mould’s video on quartz watches? Edit: checking the views on Dom’a other videos, I think the better question is who *didn’t* come from Steve’s video? 😂 Glad he mentioned your channel Dom, your channel really was a great find! Keep up the great content. 👍

[@abbaszaini1983]

You explained it very wel,l good job.

[@DomBurgess]

Thank you! :)

Clock, dial in, tune in, and you’ll see it in a heartbeat.

[@elrumorli]

I follow a lot of science related channels and you... You have potential right here, keep up the good work, I've suscribed

[@JBDazen]

I want to put a sidenote to this 'one pendulum swing is one second' thing. That doesn't apply to all pendulum clocks. Some have huge pendulums so will have different frequencies.

[@legitayush]

I subscribed to you years ago. I expected you to have gained many more subs by now. KZbin is doing you dirty man :( Their algorithm sucks. Keep posting you'll get there one day tho!!!

[@Dreadnought33]

You just gained a new subscriber. Amazing video. Keep up the good work

[@raduorza883]

Great video! I've been 'sent' here by a description from a video from Steve Mould's channel. Also subscribed! :D

[@ChitranjanBaghiofficial]

that intro is scary, like when you enter some carnival festival and there is a ride called the scary mad scientist, and that may have this type of intro.
