Earth has đź’•

Earth is actually made up from two planets which came together in a head-on collision that was so violent it formed the Moon, scientists have concluded.

Initially it was believed that the Moon was created when a smaller planet called Theia grazed the Earth and broke up, sending a smaller chunk into space where it was caught in Earth’s gravity.

Science! Found at The Telegraph.

A Toyota on Mars: Addendum

Remember the scene from the Arnold Scwharzenegger Conan the Barbarian where Conan becomes a musclebound superhero because some evil bastards make him push a grinding wheel for ten years?

Let’s say Conan has to apply 50 pounds of force. That’s 222 newtons. That lever-arm looks to be about 2 meters long, for 444 newton-meters of torque at the axle. The wheel isn’t turning very fast: I’d judge about 1 rotation per minute, which is 2 * pi radians divided by 60 seconds, or 0.1 radians per second. 444 newton-meters * 0.1 per second (radians isn’t an actual unit, so we can drop it) means 44.4 Watts total power, or a pathetic 0.06 horsepower (Hey, it’s a kid pushing a grindstone. What did you expect?)

Really I just linked to this to be able to include The Wheel of Pain video. Best time-lapse montage ever.
