Knut Ångström
Knut Johan Ångström( 12 January 18574 March 1910) was a Swedish physicist.
He was the son of physicist Anders Jonas Ångström and studied in Uppsala from 1877 to 1884, when he received his" licentiat"- degree, before going for a short time to the University of Strassburg( Strasbourg) to study with August Kundt.
Coming back to Uppsala, he completed his doctoral degree and was appointed lecturer in physics at the new university college in Stockholm( now Stockholm University) in 1885.
After a few years working there, he returned to Uppsala in 1891 and received the professorship of Physics in 1896.
He focused his research work on investigating the radiation of heat from the sun, terrestrial nocturnal emission and its absorption by the Earth's atmosphere, and to that end devised various delicate methods and instruments, including his electric compensation pyrheliometer, invented in 1893, apparatus for obtaining a photographic representation of the infra-red spectrum( 1895) and pyrgeometer( abt. 1905).
In 1900, Herr J. Koch, laboratory assistant to Knut Ångström, did not observe any appreciable change in the absorption of infrared radiation by decreasing the concentration of CO2 up to a third of the initial amount.
This result, in addition to the observation made a couple of years before that the superposition of the water vapour absorption bands, more abundant in the atmosphere, over those of CO, convinced some geologists for a time that calculations by Svante Arrhenius for CO2 warming were wrong; though subsequent work in following decades eventually vindicated Arrhenius.
The experiment, however, was careless seen from the current perspective with erroneous result but of a historical significance in the development of the theory of the greenhouse effect amplified by CO.
He was elected a member of the Royal Swedish Academy of Sciences in 1893.
Jonas Wallerstedt
Anders Jonas Wallerstedt( born 18 March 1978 in Linköping) is a former Swedish footballer and current coach, who currently is the Manager of the Tipselit team of GIF Sundsvall.
He is known for his aerial and goal scoring abilities.
He is nicknamed" Walle" by both fans and teammates.
During his career he has represented three clubs in the Swedish top flight, Allsvenskan, and was a part of the IFK Göteborg team that won 2007 Allsvenskan.
He was also the first Swedish player to have played in the Russian Premier League.

Angström (crater)
Ångström is a small lunar impact crater located on the border between Oceanus Procellarum to the west and Mare Imbrium to the east.
To the south is a formation of mountains rising out of the mare named the Montes Harbinger.
To the east are some wrinkle ridges named the Dorsum Bucher and Dorsa Argand.
This crater is bowl- shaped, with a circular rim and inner walls that slope down to the small central floor.
It has a higher albedo than the surrounding" maria".
Ångström crater is named after Anders Jonas Ångström, a Swedish physicist and one of the founders of the science of spectroscopy.
