[digitalradio] New Solar Cycle 24 Sunspot Group Forms
Greetings from chilly Rochester, VT where I'm still on vacation. Posted Saturday November 14, 2009 at http://www.wcflunatall.com/nz4o4.htm Yesterday a new solar cycle 24 sunspot group emerged in the SW quadrant of the Sun near S27W53. It currently contains a beta magnetic signature capable of producing very small B class solar flares. It remains to be seen if NOAA/SWPC will assign it #11031 before it fades or sets around the west limb of the Sun. Solar cycle 24 continues to slowly but steadily become more active. 73 GUD DX, Thomas F.

[digitalradio] Kurzweil on exponential progress
http://www.youtube.com/watch?v=qRDqvnPfIfcfeature=player_embedded In this presentation, Kurzweil refers to Cooper's Law. We're familiar with (and daily enjoy the benefits of) Moore's Law, which predicts an exponential increase in the number of transistors that can be placed on an integrated circuit, progress that began in the early 1970s: http://en.wikipedia.org/wiki/Moore's_law Cooper's Law predicts an exponential increase in the number of conversations (voice or data) that can theoretically be conducted over a given area in all of the useful radio spectrum, a progression that began with Marconi in the early 1900's: http://www.arraycomm.com/serve.php?page=Cooper Martin Cooper was the lead engineer of the Motorola team that developed the handheld mobile phone. 73, Dave, AA6YQ
