It&#39;s true, although we&#39;re pretty sure Albert never imagined that his thought experiments would lead to a Global Positioning System. Without knowing how relativity affects satellite signals, the worldwide GPS system would be worthless. Here&#39;s why...</span></p> Wed, 16 Oct 2013 15:54:01 +0000 Jerry McCoy & John Henshaw 47961 at http://publicradiotulsa.org GPS and Einstein's Relativity Who Knew That a Giraffe's Heart Had Such a Big Job? http://publicradiotulsa.org/post/who-knew-giraffes-heart-had-such-big-job <p><span style="line-height: 1.5;">What can weigh more than 25&nbsp;lb, measures about 2&nbsp;ft, beats at twice the rate and has double the blood pressure of a human heart?

AC / DC: The Inside Story On The Electric Power War http://publicradiotulsa.org/post/ac-dc-inside-story-electric-power-war <p>You'd think it would be a simple matter to generate electrical power and bring it into your home. Turns out that in the late 1880s, there was a <a href="http://en.wikipedia.org/wiki/War_of_Currents">War of the Currents</a> between two titans of industry vying to sell incompatible electric transmissions systems to America. John and Jerry fire up the time machine for a glimpse of the battle which makes today's technology fights pale in comparison.</p> Fri, 09 Aug 2013 16:21:32 +0000 Jerry McCoy & John Henshaw 44261 at http://publicradiotulsa.org AC / DC: The Inside Story On The Electric Power War The Human Voice: How Can Something So Tiny Sound So Loud? http://publicradiotulsa.org/post/human-voice-how-can-something-so-tiny-sound-so-loud <p>It's a miracle: a small flap of skin about the size of a dime or a quarter can produce sound which will fill a room when modulated by vocal folds and our body's resonant cavities.
