Thuban (α Dra, α Draconis, Alpha Draconis) is a star (or star system) in the constellation of Draco. A relatively inconspicuous star in the night sky of the Northern Hemisphere, it is historically significant as having been the north pole star in ancient times. ~http://en.wikipedia.org/wiki/Alpha_Draconis

When I was a kid I had recurring dreams about an alligator man. This was before the 1980′s TV series V mind you. But it was a vivid and scary dream for me. The alligator man had the body of an alligator with human arms and half human legs with a fully human head of a nerdy guy with glasses. He wasn’t friendly however.

I’d usually see him in the dream before he saw me, but as I looked at him he would suddenly turn and look right into my eyes and begin to chase me. I always ran. Sometimes I was able to fly very slowly by flapping my arms. It was a tortuous half-escape that always ended with me waking up just before getting caught.

Edmund Halley was a brilliant English astronomer whose mathematical calculations pinpointed the return of the comet that bears his name. Halley was fascinated by the earth’s magnetic field. He noticed the direction of the field varied slightly over time and the only way he could account for this was there existed not one, but several, magnetic fields. Halley came to believe that the Earth was hollow and within it was a second sphere with another field. In fact, to account for all the variations in the field, Halley finally proposed that the Earth was composed of some four spheres, each nestled inside another.
