Hello All ! I'm new here and this is my first post. My disclaimer is that I am not a scientist, just a very curious software developer that wishes he was a scientist! I was wondering just how super cooled elements such as Hydrogen , Nitrogen and Oxygen are made. Are these elements placed under great pressure to achieve the temperatures that are several hundred degrees below zero? Please accept my apologies for such a rudimentary question! Thanks in advance Scott
