i think it was like a momentum thing, with a similar concept to a newtons cradle. if you've seen the movie "Robots", it was part of the crosstown express where its a wheel running along to wires and it twists and whatnot. i know it was available to buy because my dad had one but he can't remember what it's called. anyone know what it was called?

Ok, Edison was a great genius, yet, there was also Tesla, whom I´ve read had worked with Edison. Well, I know Tesla came to the US already bearing a Phd, but Edison had none. I heard Edison stole most of Teslas ideas and then marketed them earning all the credit for Teslas discoveries. Is that remotely true?

I was on a flight watching the computer screen display info about speed, altitude, etc. This was on a clear calm evening. The temperature at 15,000 feet was 17°F (-7°C). Surface temperature was 54°F (12°C). Using the lapse rate of 3.6°F per 1000 feet, shouldn't the temperature have been much colder, like 0°F?

I've been thinking about projecting images onto the night sky for a special event sometime next year. I'm willing to spend any amount for existing technology (even by the billion).

Whether you believe God or the big bang theory, I want to hear opinions on if you think there have to be other planets exactly like ours out there with some form of life on it. I heard there are so many galaxies that we don't even know of and millions of planets we don't know about.

Walked in the same direction. Walking in the opposite direction to the way the world turns would this stop the world from spinning?
