Here we'll look at the question, how does quantum physics impact you? so quantum physics, when you read about it, may seem very abstract and esoteric.
00:13
But if you think about almost all the technological advances that have come about in the last 50 years, say, many of them have at heart quantum physics.
00:27
So think about what you use on a daily basis.
00:30
Think about your cell phone, for example, and especially gps.
00:42
So gps allows you to navigate, and that depends on an invention known as an atomic clock, which uses the very precise atomic transitions in materials such as cesium in order to keep very accurate time.
01:06
And since we know about relativity, keeping accurate time and getting clocks to synchronize is necessary to locate your position in space.
01:21
And that's all very interesting how that works.
01:25
But in terms of your cell phone or the way we communicate, you may think that it's just waves.
01:38
That are leaving your cell phone.
01:41
But communication networks are tied together through a series of fiber optics and lasers.
01:52
And lasers, again, fiber optics, not so much.
01:56
We've been using glass and things like that to guide light for a while.
02:03
But lasers work off what's called light amplification through the stimulated emission emission of radiation, and these work off of, again, atomic transitions inside of materials like neon rubium and maybe some of the same materials that we use for atomic clocks.

If you think about how you spend a lot of your time on the internet or on a computer, maybe it's on your cell phone, but computers, think about all the.....
