Communion Of Dreams

Magnet magic, with a twist.

Via BB, fun with physics:


I think it’s particularly clever that they made the track a Möbius strip, in order to demonstrate how the gravitational field can be used to both float and suspend the superconducting magnet. Reminds me of this bit from chapter 5 of Communion of Dreams:

The man was a bit of a lunatic. But he was a brilliant engineer who had an almost intuitive understanding of the Apparent Gravity phenomenon, and was the first to propose that it could be adapted for use as a propulsion system. He figured out a way to trick an AG field into thinking that it was in a stable inertial reference by projecting it in front of a ship, and thereby essentially have the ship – and generator – continuously ‘fall’ into the field. The Hawking was the first ship equipped with the new reactionless drive system.

Remember, both Communion of Dreams and Her Final Year will be free all next week
