1650: Monk, cosmographer, and cartographer Vincenzo Coronelli born. He will gain fame for his atlases and globes; some of the globes will be very large and highly detailed.
1694: Mathematician, astronomer, and crime-fighter Christiaan Huygens reveals in autobiography that he uses statistical analysis and games of chance to catch math criminals in the act.
1705: Mathematician Jacob Bernoulli dies. He discovered the fundamental mathematical constant e, and made important contributions to the field of probability.
1821: Mathematician and academic Arthur Cayley born. He will be the first to define the concept of a group in the modern way, as a set with a binary operation satisfying certain laws.
1899: Chemist and academic Robert Bunsen dies. He investigated emission spectra of heated elements, and discovered caesium (in 1860) and rubidium (in 1861) with the physicist Gustav Kirchhoff.
2017: Researchers publish new evidence that "suicide-by-Ultravore" is on the rise.
