February 9  - Mathematics Knowledge History

1883 The very first issue of Science is published. The first item in the “Weekly summary of the progess of science” contains a report by Thomas Craig that “Lindemann gave a proof of the fact that π cannot be a root of an equation of any degree with rational co-eficients.

1986 Halley’s comet last reached perihelion. The next return to perihelion will be on 28 July 2061. (Mathematics helps to predict such long terms events with such precision.)
