Cryogenics Cryogenics In physics, cryogenics is the production and behaviour of materials at very low temperatures. A person who studies elements that have been subjected to extremely cold temperatures is called a "cryogenicist". It is not well-defined at what point on the temperature scale refrigeration ends and cryogenics begins, but scientists assume a gas to be cryogenic if it can be liquefied at or below . The U.S. National Institute of Standards and Technology has chosen to consider the field of cryogenics as that involving temperatures below . This is a logical dividing line, since the normal boiling points of the
Doctrine of the Mean described as the ["unswerving pivot" = Ezra Pound] 'unwobbling pivot' or "zhongyong". "Zhong" means bent neither one way or another, and "yong" represents unchanging. In James Legge's translation of the text, the goal of the mean is to maintain balance and harmony from directing the mind to a state of constant equilibrium. The person who follows the mean is on a path of duty and must never leave it. A superior person is cautious, a gentle teacher and shows no contempt for his or her inferiors.
