cold enough that molecules basically give up and stop arguing.
means relating to the production and behavior of materials at extremely low temperatures, typically below minus 150 celsius.
from from greek kryos meaning icy cold, plus genic meaning producing — coined in the 19th century as scientists chased ever-lower temperatures to liquefy gases once thought impossible to liquefy.
absolute zerominus 273.15 celsius, technically unreachable
heliumstays liquid even near absolute zero
superconductorslose all electrical resistance when chilled
nasa rocketsburn liquid oxygen and hydrogen, both cryogenic
for instance
large hadron collider — magnets cooled to 1.9 kelvin, colder than deep space
spacex falcon 9 — uses subcooled liquid oxygen near minus 207 celsius
alcor life extension — stores bodies in liquid nitrogen at minus 196 celsius
mri machines — rely on cryogenically cooled superconducting magnets
