Beamish and Day are the only researchers in Canada conducting experimental research in this area of fundamental physics. At very low temperatures, helium gas turns into a liquid. Put under extreme pressure the liquid turns into a solid. Physicists have been manipulating solid helium so they can study its unusual behaviour. In 2004, a research team at Penn State university in the United States, led by Dr. Moses Chan, electrified the physics world when it announced that it may have discovered an entirely new state of matter - supersolidity. The team made the discovery by cooling solid helium to an...
