Atomic Timekeeping Podcast Episode 13

Believe it or not, it's almost time to go back to Daylight Saving Time here in the United States. (I'm getting tired of Daylight Saving Time.) Apart from my annual whining about the month of February in general (which just isn't my favorite month), I do have a few useful things to share in this podcast episode. And, for those of you who are interested, please watch three, one-hour shows about the scientific concepts of "time" on "The Science Channel" on the evening of Sunday, March 1, 2009. Check your local listings for Earth Time, Cosmic Time and a program called What Time Is It?.

Also in this podcast episode, I wonder why an AM/FM "Clock Radio" alarm clock with atomic timekeeping is either rare, expensive or unreliable. But here are a few links you can try...

Atomic Timekeeping Podcast Episode 12


Warning! This episode contains audio test tones. I'll explain why I'm playing the test tones but, in the meantime, make sure you're not listening to this episode at high volume settings. If it's too loud, those test tones might be a little bit too surprising to your ears.

So, yes, I'm talking about audio in this episode and how it relates to "Time Frequency." Time Frequency is one of the four major things that are measured by those top-level scientists at the National Institute of Standards and Technology. (It'll make more sense if you just listen to the episode.)

Also in this episode, I share a very nice email from Alan in the UK. Here's a link to his blog.

So, that's all for now. Enjoy the podcast!
