Created by the online science museum, Emergent Universe, this flash mob illustrates the behaviour of electrons in a superconductor. As explained by the site:
In a metal, electrons flow like a gas through a grid of metal ions. When the temperature is above the critical temperature, Tc, and the superconducting material is in its normal, non-superconducting state, these electrons move nearly independently of one another. When the temperature drops below Tc and the material enters its superconducting state, these electrons, like the dancers here, pair up. The electron pairs can then lower the overall energy by synchronising their movements with the other pairs, such that all pairs move cooperatively torgether as a single, coherent entity.
SCIENCE has explained nothing; the more we know the more fantastic the world becomes and the profounder the surrounding darkness. Aldous Huxley, 1894-1963.
This blog resides firmly at the intersection of scientific research, education, art, and communication. Herein lies information and current happenings related to each, as well as any other sciencey goodness worth sharing.
