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. | |||

1590: Astronomer and crime analyst Tycho Brahe publicly accuses rogue astronomers associated with the House of Malevecchio of committing a series of high-profile crimes against astronomical constants.
1634: Minister, scholar, astronomer, mathematician, and crime-fighter Wilhelm Schickard writes two letters, each describing a new technique for detecting and preventing crimes against astronomical constants.
1873: Physicist and engineer William D. Coolidge born. He will make major contributions to X-ray machines, and develop ductile tungsten for incandescent light bulbs.
1973: Watergate scandal: President Richard M. Nixon agrees to turn over subpoenaed audio tapes of his Oval Office conversations.
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.
2016: Steganographic analysis of The Eel Time-Surfing reveals quantum gravity control software based on spin foam models.
