Everytime I comment on your citations, you go into a snit about how "Gramps" is insulting the "whippersnappers." For all I know, in Real Life you're older than me, or you're some guy working a guard job at Lockheed. Or both. Or you may be the grad student at Hoboken State College you appear to be. Whatever, I know that your main method of argument is either a bunch of "Bah" comments followed with cites apropos of nothing you've dug up. Such as your refutation of category theory by digging up some of the usual computer vision and scene analysis junk that's been going around for 40 year. I stand by my comment that shielding a thread in a $100 bill, for example, is vastly easier than detecting it. Your cites about WiFi frequencies and 3 meter ranges and suchlike don't mean much. (As it happens, and you'll go into your "whippersnapper" rant for my mentioning names, but I'm an early investor in one of the leading ultrawideband (UWB) companies, one competing with the better-known Time Domain. Their antennas are launching high-current pulses in WiFi and even higher frequencies...the tagline is always "DC-to-daylight," of course, but 99% or so of the radiated power is in the .5-10 GHz band. I was up at their lab last Friday, checking on progress, walking around inside the cargo shipping container they've got set up at their place, and looking down on Skywalker Ranch below them. UWB may turn out to be useful, but it has nothing to do with detecting threads embedded in Ben Franklins.) > A long range ID system > http://web.tiscali.it/homeglobal/issues/0111/Nov01-07.pdf > > Utilising the internationally approved 2.45Ghz UHF band allows > specialised > readers to access the information contained in transponders at a > distance of up > to three metres.

It can only exist until the voters discover that they can vote themselves money from the Public Treasury. From that moment on, the majority always votes for the candidate promising the most benefits from the Public Treasury with the result that a democracy always collapses over loose fiscal policy always followed by dictatorship." --Alexander Fraser Tyler
