Liquid helium belongs to a class of fluids known as quantum fluids, as distinct from classical fluids.
I look back upon graduate school as being a very happy period in my life. The chance to be thoroughly immersed in physics and to be surrounded by friends pursuing similar goals was a marvelous experience.
Following graduation from high school in 1948, I attended Harvard University where I became a physics major. Having grown up in a small town, I found Harvard to be an enormously enriching experience. Students in my class came from all walks of life and from a great variety of geographical locations.
There are few moments in science in which you genuinely are excited. The discovery of superfluidity in helium-3 was one of those moments.
Modern low temperature physics began with the liquefaction of helium by Kamerlingh Onnes and the discovery of superconductivity at the University of Leiden in the early part of the 20th century.
