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.
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 RU-vid that to gain some motivation. You gave me the motivation to continue reading and not to be lazy, thanks!
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?
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!
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. :)
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
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!
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.
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.
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.
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?
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.
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".
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. 👍
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!
I subscribed to you years ago. I expected you to have gained many more subs by now. RU-vid is doing you dirty man :( Their algorithm sucks. Keep posting you'll get there one day tho!!!
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
