The Big Leonid Show and Tin Foil

Nov 16 at 5:05pm by Aileen

I hope that readers are as eagerly looking forward to the big Leonid meteor shower show as I am. Planning to schlep a lawn chair to the railroad tracks where there is an unemcumbered view of the east/southeast sky and no light pollution to speak of, settle in with a blanket and toast to the solar system’s fireworks display.

It should be quite the spectacle if predictions are correct. It’s a new moon, so that source of light pollution won’t be an issue. They say we’ll only get 20 to 30 an hour, while Asia gets the really big boomers at 200-300 an hour, but I’m hoping they’ve miscalculated a bit. There should still be a few to see tonight. The Leonids put on their show every year as the planet travels through the remains of the Tempel-Tuttle comet. Our pass-through has the incoming debris originating from the direction of the constellation Leo, hence the name. This year, however, Mars is sitting right between us and the constellation, so it should look like our friendly neighborhood Martians are staging the show!

What I will not be doing is wearing a tin foil helmet to prevent those Martians from manipulating my brain waves. According to MIT research conducted in 2005, the metallic fashion statements actually amplify invasive radio frequencies reserved for use by the government in satellite communications rather than protect wearers from what they are most afraid of.

The abstract of On the Effectiveness of Aluminum Foil Helmets reads:

“Among a fringe community of paranoids, aluminum helmets serve as the protective measure of choice against invasive radio signals. We investigate the efficacy of three aluminum helmet designs on a sample group of four individuals. Using a $250,000 network analyser, we find that although on average all helmets attenuate invasive radio frequencies in either directions (either emanating from an outside source, or emanating from the cranium of the subject), certain frequencies are in fact greatly amplified. These amplified frequencies coincide with radio bands reserved for government use according to the Federal Communication Commission (FCC). Statistical evidence suggests the use of helmets may in fact enhance the government’s invasive abilities. We speculate that the government may in fact have started the helmet craze for this reason.”

Oh, well. Before some reader out there comes back with the obvious, yes I do know this is mostly tongue-in-cheek from a few undergrad CompSci geeks with way too much time on their hands. But it’s still pretty funny, so enjoy!
