Sunday, April 1, 2012: This is the day that we remember and celebrate the life of German physicist Heinrich Hertz. He is credited with proving that electricity can be transmitted in electromagnetic (radio) waves. He lived just a brief 36 years from 1857 to 1894, but made a huge impact on our world. Back on April 1st, 1960, the radio frequency spectrum numbering scheme was converted from "cycles per second" to Hertz. This caused quite a bit of confusion among scientists and the public alike. Most learned the new way within a year or so. Einstein's Theory of Relativity comes into play here as well, causing further uncertainty. A throwback to the old days are radio dials labeled with CPS (cycles per second), KC (kilocycles), and MC (megacycles). If you should come across a relic radio built before 1960 and want to tune into your favorite radio station, you need to convert the station frequency from say, 103.5 MHz (Megahertz), to Megacycles. There is a mathematical formula that does the work for you. Subtract 10 from the Frequency in MHz and then take the square root and multiply that number by itself. Add 10 to get the frequency in Megacycles. That will get you pretty close. For the math challenged, there is a graph here to help with the conversion. Remember, Heinrich Hertz is to blame for all of this.
