Karl F. Sundman

Karl Frithiof Sundman (28 October 1873, in Kaskinen – 28 September 1949, in Helsinki) was a Finnish mathematician[1] who used analytic methods to prove the existence of a convergent infinite series solution to the three-body problem in 1906 and 1909.[2][3][4] He also published a paper on regularization methods in mechanics in 1912.

Awards, recognition

Sundman was awarded the Pontécoulant prize by the French Academy of Science in 1913 for this work.[1] In 1947, Sundman was elected a foreign member of the Royal Swedish Academy of Sciences. The crater Sundman on the Moon is named after him, as is the asteroid 1424 Sundmania.

gollark: Which is arguably bad if you're *using* the currency, but means that a shared one is likely to cause politicking/not be adopted anyway.
gollark: A big issue with this is that in these days of modern economic whatever, control of a currency also allows financial hax which governments want to be able to do.
gollark: (And health services still have to prioritize treatments based on cost; they cannot give everyone arbitrarily expensive treatments)
gollark: Government incentives aren't always aligned with those of the people.
gollark: Post-scarcity would be if you could trivially provide it for free.
