Adam Arndtsen

Adam Frederik Oluf Arndtsen (15 December 1829 – 7 August 1919) was a Norwegian professor and physicist.[1]

Biography

Arndtsen was born at Alstahaug in Nordland, Norway. He was the son of Ole Arndtsen (1786-1846) and Wilhelmina Castberg (1788-1853). He studied at the Royal Frederick University (now University of Oslo) earning his cand.med. in 1849. In 1854, he took a job as a physics teacher at the Norwegian Military Academy. In 1859 he lost out to Hartvig Caspar Christie in a competition to succeed Lorentz Christian Langberg as an academic of physics at Royal Frederick University.[2]

In 1857, a scholarship brought him abroad to train with Wilhelm Eduard Weber (1804-1891) at Georg-August-Universität of Göttingen and Émile Verdet at the École normale supérieure in Paris. Arndtsen was appointed at the Rikshospitalet in 1860. In 1864 he was awarded the Crown Prince's gold medal (Kronprinsens gullmedalje) for the dissertation regarding the use of electricity in medicine (Om Electricitetens Anvendelse i Medicinen).[3]

He was a professor of physics teacher at the Norwegian Military Academy from 1873 until 1903. He became the first director of the Norwegian Metrology Service, serving from 1875 to 1914. From 1900 to 1914 he also represented Norway in the International Bureau of Weights and Measures. In 1897, he was awarded the Order of St. Olav[4]

Selected works
gollark: If you tracked clicks on each internal link you could estimate connection importance that way. Or manually specify importance levels. Or have something to emphasise links between big clusters.
gollark: > it seems like you're talking more about an API?Yes, I think the ability to do that might be more useful to (some) external services than having UI in Athens itself.> Dokuwiki does seem interesting thoughIt's a pretty good selfhosted wiki engine. It doesn't have knowledge-graph-y features because it was mostly made before that became a topic of interest, but does have... search, links, somewhat okay formatting, and many plugins. I currently run an instance because it seemed the best available stable thing when I was setting up things and it is quite hard to migrate now.
gollark: Sorry if I'm explaining this somewhat badly. I can probably clarify. I mean something like this (https://www.dokuwiki.org/plugin:struct) but without necessarily having to define a schema somewhere. I think this would be good for a few categories of thing, such as, say, exporting a list of cards (defined in notes) into a spaced repetition system. Possibly calendar events/reminders too, but you'd probably want a way to remove expired ones.
gollark: Regarding integration/plugins (I didn't see this being thought of here before or on github when I did a search, but my queries might have been bad): a nice/general way to integrate some types of external service without having to integrate per-service code could be to have a way to have blocks containing arbitrary machine-readable data (with a nice UI to edit it) and a type field, and an API to find all/all recent blocks with a given type.
gollark: It has fancy diagrams.
