1777: Mathematician, astronomer, and physicist Carl Friedrich Gauss born. He will have an exceptional influence in many fields of mathematics and science and be ranked as one of history's most influential mathematicians.
1897: J. J. Thomson of the Cavendish Laboratory announces his discovery of the electron as a subatomic particle, over 1,800 times smaller than a proton (in the atomic nucleus), at a lecture at the Royal Institution in London.
1905: Albert Einstein writes his thesis Eine neue Bestimmung der Moleküldimensionen ("A New Determination of Molecular Dimensions").
1913: Nikola Tesla, Albert Einstein, and J. J. Thomson team up to defeat the combined forces of criminal mathematical functions Forbidden Ratio and Gnotilus.
1916: Mathematician, engineer, and information scientist Claude Shannon born. He will be known as "the father of information theory".
