HOW TO build weather computers…


Dave Matthews Band encouraging fans to bypass DRM restrictions on new album (and, funny enough, petitioning Apple to ignore DRM restrictions in iTunes). Their HOW TO suggests burning a CD, then importing it in to iTunes, that’s wrong. Just hold down the shift key and/or disable autorun (here’s how). [via] Link.


…build and operate a mechanical device to simulate, remarkably well, what happens when a robotic spacecraft takes advantage of a “gravity assist” on its interplanetary trajectory through the solar system. The device substitutes a strong, moving magnet for a massive orbiting planet, and a steel bearing ball (BB) for a spacecraft. The “magnetic assist” it provides to the BB is closely analogous to the “gravity assist” a spacecraft can receive from a planet moving in its solar orbit. Link.
