Atomic Clocks: The clocks that keep the world on time

A continuation of my last video on how quartz clocks function. Atomic clocks are used around the world work together to create the time standard we all live by. The atomic clock uses an ingenious process that relies on the very stable and reliable quantum properties of electrons in specific atoms to keep crazy accurate time. Several diverse things you might not expect, like credit cards, encrypted phone calls, and GPS would not be possible without atomic clocks.

Thank you again so much to Dr. Judah Levine from the National Institute of Standards and Technology (NIST) for your time and help on this video. I was over the moon after speaking with you.

And a big thanks to Tom Van Baak for letting me use your images.

I am a physicist working with atomic clocks at the German Aerospace Center. This video is outstanding. Easy to understand, but without sacrificing the scientific accuracy. Kudos to you!

Thanks! 😊 Btw, I also had a chance to talk to Dr. Judah Levine, at a conference some months ago. He's an AMAZING person. Gave me a bunch of new ideas to work on

Well done, referencing credible sources that can be verified in today's world of KZfaq is so very important. My kids and I will be tuning-in more, thank you! Horology is fascinating to me.

did anyone else think digital clocks were controlled by one clock in each time zone and that’s how they were always on time or how they changed for daylight savings when they were little? it’s cool to see how atomic clocks are actually controlled!

Somehow I get a notion, that it is the speed or abundance of atoms flying through detector what sets frequency not the atoms with higher energy state🤷‍♂️

Well I read a bunch of books from over close to the science building and now if I was going to try and get out of a job at the bricks factory by telling a bronze age Pharaoh that I have a higher education then I would probably put the spotlight on the way that, given an office for it, I could eventually find out the size of the earth from the length of a pendulum. Apart from the metrics of all of this and how many meters it is you can tell that I would be ahead of all of his other astronomers, no mater what units they have, since, unlike them, I am the one who noticed the formula for the antisine in a handbook. I tested it out and it multiplies right up close to pie to prove it and by now, knowing the schoolbooks, I could also clock the period of a pendulum from the time it would take for a star to get from one hole in my ladder to another one. Of course you don't make a meter stick out of it before all of this would take some amount of setting up and the pendulum formulas are known to the schoolbooks and so also the earth but if I ever got around to talking about an atomic clock to get out of a job at the bricks factory then what I would tell them is that future times will have sciences that no one could ever learn since you can tell from because for example an atomic clock would cost the labor power of many millions of workers, for many decades, or centuries, and then by the time it gets done the people who have their diplomas will cook up such technologies that it would take many specialists to get any of them to work.
