I read in sci.electronics.design that Cecil Moore wrote (in ) about '1/4 vs 1/2 wavelength antenna', on Wed, 2 Mar 2005: Richard Clark wrote: There are no sine waves in nature, so by this contortion of logic from above there are no s-domains (?). Why are there no sine waves in nature? Because nature is bounded by the Big Bang (a discontinuity) at one end, and has yet to fulfill its infinite extent. One would think that a 12 billion year windowing would be close enough. :-) Not only that, but since by definition the Universe started at T=0, any 'sine wave' that starts at a positive zero-crossing is at any later time indistinguishable from a real one that started at T=0. Not if we were there the moment the later wave turned on. I heard that amateur operators hate splatter. RC appears to be an exception, however. |
