7.17 Applications of Substances at Low Temperature
Mysteries are the actions of science and its followers, i.e., researchers. There is no end of scientific achievements; when one thinks that limit has been reached, new horizons emerge. The low temperature domain has provided researchers wide field to tread. Normally, electricity flows through a conductor which waste nearly 50 per cent of the power produced. Scientists are trying to get rid of this phenomenon by looking after carriers of electric current which can be made super conductive so that this waste of energy is avoided. Dutch physicist Heike Kamerlingh Onnes (1853–1926) discovered superconductivity in 1911 while studying the variation of electrical resistance of mercury with temperature. ...
