Comment Re:Back to the Future (Score 1) 658

Actually, in the most likely form of a universe permitting reverse time travel, specifically an Everett multiverse, next week's lottery numbers would be completely useless. Simply put, you'd go back in time with the numbers, and then the drawing would come up and it wouldn't be the same numbers... because you'd be in another branch of probability (Hilbert) space.

Comment Re:2.4GHz (Score 1) 141

Well, part of the reason it is all there (and other ISM bands like 915 MHz and 5.8 GHz) is because the stuff *can* work with interference. This property is useful both when dealing with other "intentional radiators" and with industrial emissions, so it makes sense to put them in the same area. Pretty much the FCC and other regulatory agencies put an (almost) free-for-all sign up and said "if you can make it work, go for it, just don't complain if it doesn't work at all." However, you wouldn't be able to use the ISM bands -- or, quite frankly, any frequency close to them -- for weak-signal work like satellite. It would be like trying to whisper at Woodstock.

Comment Re:Old rumour regarding US nuke launch codes... (Score 1) 231

This, of course, was a very dangerous case of insubordination on the part of the military, since the exact reason it was imposed on them was that the political leadership considered the risk of an unauthorized launch to be greater than the "last man standing" scenario, and, guess what, in the United States the political leadership is supposed to be supreme to the military.
