Resumen de Crystal inspired by elegant satellite dance
Crystals are normally regular patterns of unmoving atoms or molecules. But now a team of physicists has proposed a "choreographic crystal that gets its order from movement. Latham Boyle of the Perimeter Institute for Theoretical Physics in Waterloo, Canada, got the idea while studying the most symmetric way to organize four satellites. For four static points, the most symmetric arrangement is as a regular tetrahedron, which looks like a triangular pyramid. There are 24 ways to rotate or reflect this solid body without noticeably changing it. But if the points move in circular or elliptical orbits, there's no way to maintain that 3D shape.
