He discovered the Czochralski method in 1916, when he accidentally dipped his pen into a crucible of molten tin rather than his inkwell. He immediately pulled his pen out to discover that a thin thread of solidified metal was hanging from the nib. The nib was replaced by a capillary, and Czochralski verified that the crystallized metal was a single crystal. Pic.

  • 2014: Physicist and academic Tullio Regge dies. In 1968 he and G. Ponzano developed a quantum version of Regge calculus in three space-time dimensions now known as the Ponzano-Regge model; this was the first of a whole series of state sum models for quantum gravity known as spin foam models.
