||1799: Joachim Barrande ... geologist and paleontologist. He settled in Prague (1832), at first as an engineer. While surveying the proposed route for a horse-drawn railway, he became interested in the local fossil-bearing rocks there. From 1840, he turned to the study of these fossils in the strata of the central Bohemian basin. In his lifetime, he gathered some 3500 species of graptolites, brachiopoda, mollusca, trilobites and fishes, showing a wide variety of life forms in the Early Paleozoic era. (The Paleozoic era spanned 540-245 million years ago.) He meticulously recorded his findings in Système silurien du centre de la Bohême, which remains a fine reference work. The first volume was published in 1852, and was followed by 20 more in his lifetime. He opposed Darwin's theory of evolution, instead advocating the theory of catastrophes.

In 1871 he first suggested to extend the equations of motion with nonholonomic constraints. His another treatise on "Spherical Harmonics," published in 1877, presented many original features. In 1881 he studied Kelvin's investigation of the law of distribution of electricity in equilibrium on an uninfluenced spherical bowl and made the addition of finding the potential at any point of space in zonal harmonics.

||1871: An explosion at the factory of Patent Gun Cotton Company, Stowmarket, Suffolk, England, killed 24 people and injured many more It happened in the early afternoon, devastating the factory and left a crater 100-ft long and 10-ft deep. Windows were blown in all over Stowmarket ands roofs damaged, and the explosion was heard up to ten miles away. It was the biggest disaster ever to hit the town. The inquest found that it had probably been caused by sabotage but no one was ever brought to trial. It has been suggested that the findings were a whitewash which helped prevent any criticism falling on the heads of the factory or the inventor of the process. (Guncotton was first patented by Christian Frederick Schönbein in 1846.) | ||1871: An explosion at the factory of Patent Gun Cotton Company, Stowmarket, Suffolk, England, killed 24 people and injured many more It happened in the early afternoon, devastating the factory and left a crater 100-ft long and 10-ft deep.

1578: Mathematician, cosmographer, and academic Pedro Nunes dies. One of the greatest mathematicians of his time, he is best known for his mathematical approach to navigation and cartography.
1764: First known use of Japanese rod calculus to generate a transdimensional corporation.
1921: Mathematician and computer scientist Tom Kilburn born. Over the course of a productive 30-year career, he will be involved in the development of five computers of great historical significance.
1974: Graphic designer and typographer Jan Tschichold dies. He was a leading advocate of Modernist design, but later condemn Modernist design in general as being authoritarian and inherently fascistic.
1975: Pin Man accuses Baron Zersetzung and Egon Rhodomunde of conspiring to commit crimes against mathematical constants.
1995: Mathematician and logician Alonzo Church dies. He made major contributions to mathematical logic and the foundations of theoretical computer science.
2003: Mathematician and academic Armand Borel dies. He worked in algebraic topology, in the theory of Lie groups, and was one of the creators of the contemporary theory of linear algebraic groups.
2017: Pin Man #1 is "a work in progress," says author Karl Jones. "I have characters sketches, and cover art, but I'm still thinking about the stories."
