Atomic Timekeeping Podcast Episode 15

This time, it's a special video podcast. And I wanted to tell you about a style of clock which I've enjoyed for the past 30 years... the Ball Clock!

Just a little note... I was going to ramble on for a couple more minutes in my narration of this video. But then I realized that there's a 10-minute limit for YouTube videos and I wanted to make this a YouTube-friendly production. So I cut out a few superfluous details. For example, when I was a teenager I actually conditioned myself to sleep through the night with one of these noisy ball clocks running all night long in my bedroom. I wonder if I could do that again now. Hmmm.

Atomic Timekeeping Podcast Episode 14

This time, I'll talk about how difficult it is to set your own, personal, real atomic clock to "the correct time." Taking "lag time" into account, this could be a real problem. For most of us, a "radio controlled" clock is good enough but for some people, nothing is sufficient short of owning a real atomic clock. Some of these people call themselves "Time Nuts," and here are some links that will lead you to them...
