A Tale of Two Fluids: Alfred Leitner on liquid helium

A lot of my research over the years required cooling objects to ‘freeze out’ some phenomena in order to study others. Liquid helium was often essential to get to these temperatures. Its a fascinating material quite apart from its practical value as a refrigerant. Alfred Leitner’s beautiful demonstrations from 1964 give a glimpse into a liquid that continues to be actively studied by many laboratories.
