The Physics of Levitation

Levitatie: zweven, kennen we vooralsnog alleen uit Science fiction en Harry Potter verhalen. Dankzij een recente doorbraak in het natuurkundig onderzoek op het gebied van het Casimir effect komt daar echter verandering in:

[...] Professor Ulf Leonhardt and Dr Thomas Philbin, from the University of St Andrews in Scotland, have worked out a way of reversing this pheneomenon, known as the Casimir force, so that it repels instead of attracts.

Their discovery could ultimately lead to frictionless micro-machines with moving parts that levitate But they say that, in principle at least, the same effect could be used to levitate bigger objects too, even a person. [...]
