Development & applications
             What is cryogenics: cryogenics is the study of low temperatures or production of the same.Liquified gases, like liquid hydrogen and liquid helium are often used for production of very low temperature.
             Leiden, Netherlands is sometimes called "The Coldest Place on Earth", because of the revolutions in cryogenics that happened there. Some of these were the discovery of superconductivity by Heike Kamerlingh Onnes, the liquefaction of helium by Kamerlingh Onnes, and the solidification of helium by Kamerlingh Onnes' pupil, Willem Hendrik Keesom.
             The Myth: have you seen, the Stanley Kubrick/Arthur
             C. Clarke movie, "2001: A Space Odyssey"? In the movie, the
             Characters are frozen and attempt is made to bring them
             back to life There is a field devoted to freezing people, called
             cryonics It's currently used for freezing people who die of
             diseases that, they hope, will be curable by the time
             scientists learn how to revive people. At present,
             though, reviving people has been successful only in science
             fiction. And not even all the time there, if you remember what
             Both cryogenics and cryonics got their origin from Greek word "kryo" meaning "to cool". But it will be naive to confuse between cryogenics and cryonics, because unlike cryonics, cryogenics is a well established science with several scientific and practical applications.
             Applications: There are three main areas
             Of application upon which this article would concentrate. They are:
             Racing cars that move faster, golf heads that last longer, drill machine heads having longer life cycle, are some of the achievements of cryogenics in the field of material science.
