Cryogenics necessary to use a silicon diode for accuracy. 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
Cry Baby Cry Cry Baby Cry "Cry Baby Cry" is a song by the Beatles, written by John Lennon (though credited to Lennon–McCartney) from their 1968 album "The Beatles" (also known as the "White Album"). The outro of the song is a short segment referred to as "Can You Take Me Back", written by Paul McCartney, which was actually an outtake from the "I Will" session.
