The St Petersburg Academy of Science had been founded by Catherine I, the wife of Peter the Great, in 1725 and Euler had worked there since 1727. By this time Euler was getting quite old, being 62 years of age when the young mathematician Lexell arrived in 1769. However, working in the same Academy as Euler and other high quality scientists was something which Lexell found exciting and enjoyable. Euler discussed research plans with Lexell and the other mathematicians at the Academy.

Övrigt Månen Skrivet av: Eva Kumpulainen På latin heter månen Luna. Medelavståndet från jorden till månen är ca 384 400 km men eftersom månens bana runt jorden är oval så varierar avståndet. Månen är jordens närmaste himlakropp. I alla år har människor försökt tyda månen. Några tycks se ett ansikte i månen, kineserna säger att det är en hare och indianerna tycker att det är en groda. Vikingarna tyckte att de såg två kvinnor som bar ett kar mellan sig. Det har skrivits en hel del sånger och musikstycken om månen. Ett känt musikstycke är Månskenssonaten av Beethoven. Det finns även flera sagor om månen. Men man behöver inte tro på alla sagor och sånger om man inte vill. Månen är viktig för oss hursomhelst. Det är månen som skapar tidvattnet, ebb och flod, runt havskusterna. Månen har gett namn åt veckans första dag, måndagen. Det är faktiskt också månen som har lärt oss människor att dela in året i månader. Månen går upp i öster, om man nu kan säga att den går ”upp”. Egentligen går inga himlakroppar ”upp” eller ”ner”. Men eftersom jorden hela tiden vrider sig runt och vänder olika sidor mot månen, så ser det ut som att månen går ”upp” och ”ner”.

Anders Johan Lexell (December 24, 1740 - December 11, 1784) Anders Johan (sometimes in Russian: Andrei Ivanovich) Lexell was born on December 24, 1740 in Abo, then Sweden (now Turku, Finland), where he lived until 1763, and graduated at the university of Abo im 1760. In 1763, he became assistant professor at Uppsala Nautical School, in 1766 professor of mathematics. In 1768 he was invited to the St. Petersburg Academy of Science where he was appointed as professor of astronomy in 1771, and in succession of Euler, to the chair of mathematics in 1783. He died at St. Petersburg a year later, on December 11, 1784. From 1780 to 1782 he had undertaken a travel through Europe and visited Germany, France and England. Besides significant work in mathematics, mainly analysis and geometry, he contributed to astronomy his calculation of the solar parallax and the calculation of the orbits of several comets. Among these comets was one discovered by Charles Messier , the first for which a short period (5 1/2 years) was found. Lexell also found that it had passed very close to Jupiter and its moons, but while the comet changed its orbit significantly and could not be found later, the moons were uneffected; this led him to the conclusion that the comet's mass was extremely low. He also was among the first to calculate an orbit for planet Uranus as it was newly discovered by William Herschel on March 13, 1781.
