Ball Sports & physics

Par 5 site on the science of golf balls. Service on the newly sized tennis ball. Return on the flight of tennis balls: Part 1; Rally with Part 2. Back and forth again with Ball/Court Interaction 1 and 2, and the aerodynamics of tennis ball coverings puts it away for the point. (And apparently, the weight inside a bowling ball isn't spherical and so modeling the movement of bowling balls takes university papers and presentations.[PDF])

Desktop Fusion

Putterman also suggests the crystals could be used as microthrusters for tiny spacecraft. By accelerating deuterium in one direction, the spacecraft would be propelled in the opposite direction.
Ok, so I know nothing about physics, apart from what I learned getting beat up in grade school, but this seems both legit and cool. Here's a MeFi discussion of the other kind of desktop fusion, you know, the kind with the bubbles. A picture of the bubble machine.
