We take lots of things for granted in this world; GPS, the internet and of course particle accelerators (well, maybe not particle accelerators!). However, none of these things would be possible without atomic clocks.
In this video Dom explains how they work with some fascinating factoids to boot!

Steve Mould sent me here :-)
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!

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.
Sent here by Steve Mould... You're good, man! Loved your presentation!
dude, where are your subs? your shit is on the same level as Vsause, keep up the good work

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 KZread that to gain some motivation. You gave me the motivation to continue reading and not to be lazy, thanks!

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

I have been unable to grasp this concept for days, until this video made everything click! Thank you!
Hay Dom , Love this ! such great way of explaining complex stuff!! great job. And so entertaining.
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?
Me too. Came via Steve Mould
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.
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.

Great explanation. I'm wondering though, when the frequency is being corrected, how does it know if it's too fast or too slow?
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".
You just gained a new subscriber. Amazing video. Keep up the good work
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
Liked and subscribed because you deserve so much more!. Excellent explanation. :)
dude wow great video nice explanation and epic presentation 10/ 10 for me and you should have a lot more subz than that well you just earned one keep up the good work and I will share all your videos to help you a bit

Great video. Perfect mixture of explanation and humour.
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!
I follow a lot of science related channels and you... You have potential right here, keep up the good work, I've suscribed
The clearest explanation I've seen to date.
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.
Great work! You deserve more subs.
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.
Awesome stuff! Subscribed!
You speak at the perfect speed for me, others tend to go a little fast. Great video, thanks!

Great video man 🙂
You're so good! Best explanation I've found on internet. I'll suggest my friends to subscribe your channel
What an incredible quality and explanation
criminally underrated channel. YT recommendations, do your thing.
Steve Mould sent me here and now I've subbed, thanks for the video from Denmark!
My first time to your channel. I watched about 14 seconds of this video. Your good. Love the humor level. Keep doing great! Lemme hit that subscribe buttom.....done!

Great Video. Actually the best that i have seen on Atomic Clocks, BUT I have a question. In all of this, how is the measure TIME being kept ? Is it done by counting the number radio waves being generated ?
Thanks for the video!
Steve Mould sent me here. You definitely deserve move subscribers. Great content.
Wow. Such an amazing video! And it was really fun.

Great work! You deserve mo subs.
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?
Hi there I liked your video. I am looking to buy a clock where the hands constantly moves and not ticks ? what do I search online ? thanks
Awesome video. finally understood how they work. Thanks

Hey, just found out about you. KZread recommendations doing their work alright. Keep up the good work brother.
Why I dont know about this channel, very cool work. Thank you
Brilliant video👍
Do you think it's possible that a quartz or atomic clock moving at high velocity in space (through the dark matter too) could be induced to have their frequencies reduced as velocity increases? Thx
Do miniature atomic clocks work in the same way or are they slightly different?
