The Bibliotheca Alexandrina is organizing two lectures by Nobel Laureate, Professor Douglas D. Osheroff, Professor of Physics and Applied Physics, Stanford University, on the discovery of superfluidity in the isotope Helium-3 at absolute zero.
The first lecture, “So what really happens at Absolute Zero?”, sheds light on the description of some of the kinds of motion and some of their consequences, including the failure of liquid helium to solidify under its own vapor pressure even at absolute zero.
In the second lecture, “The discovery of Superfluid Helium-3 as seen through the Eyes of a Graduate Student”, Professor Osheroff explains his discovery evidence for the existence of two unexpected phase transitions in a mixture of liquid and solid Helium-3, both within three thousandths of a degree of absolute zero.
