Harvest Moon

09/28/2006 1:33 PM

With the 'Harvest Moon' of 2006 rising on October 6th, NASA came up with a fascinating story about the 'strangeness' of moonlight. Some of the puzzling things:

1. Moonlight steals color from whatever it touches.

2. If you stare at a gray, moonlit landscape long enough, it turns blue.

3. Moonlight won't let you read...

Sounds unbelievable? Read this NASA article.

I remember hearing that years ago, if you wanted to play a trick on someone, you would place their straight razor in the window during a full moon. Supposedly the moon light would unsharpen the blade.

'Cold hearted orb that rules the night
Removes the colors from our sight.
Red is grey and yellow white,
But we decide which is right.
And which is an illusion?'

I believe that's in the same category as sharpening razor blades by putting them in pyramids. I actually tried that for quite a few weeks (with before and after photomicrographs, which showed no change) when I was teaching science & physics (was it in the 70's?).

the pyramid has to be in direct relationship to the proportions of the great pyramid. try that...during the war the Russians were issued with a device that does this.

Yes, we made the pyramid to the supposedly correct proportions. It's been so long ago I don't even remember what material we used to make it! Since we don't know what kind of 'energy' we were supposedly 'focusing', there is really no way to know what properties the pyramid material should have. Until someone comes up with a repeatable demonstration to the contrary, I consider the whole pyramid thing a contrived hoax.

The full moon, when viewed near the horizon can appear to be huge, the October harvest moon should be no exception. This is an illusion, it is no bigger than a full moon high in the sky. On October 6, have a look at the moon, note it's apparent size and then hold an ordinary asprin between thumb and forefinger at arms length and note the apparent size of the asprin. No way are they the same size, right? Next, try holding the asprin (at arms length), and move it over the full moon, you will notice that it will entirely cover that huge full moon in the sky. Try this on different nights or different times of the night, no matter what phase the moon is in or its apparent size, it will always be about the same size as an asprin held at arms length.
