Erwin Madelung

Erwin Madelung (18 May 1881 – 1 August 1972) was a German physicist. He was born in 1881 in Bonn. His father was the surgeon Otto Wilhelm Madelung. He earned a doctorate in 1905 from the University of Göttingen, specializing in crystal structure, and eventually became a professor. It was during this time he developed the Madelung constant, which characterizes the net electrostatic effects of all ions in a crystal lattice, and is used to determine the energy of one ion.

In 1921 he succeeded Max Born as the Chair of Theoretical Physics at the Goethe University Frankfurt, which he held until his retirement in 1949. He specialized in atomic physics and quantum mechanics, and it was during this time he developed the Madelung equations, an alternative form of the Schrödinger equation.[1]

He is also known for the Madelung rule, which states that atomic orbitals are filled in order of increasing quantum numbers.

gollark: That post and the comments seem to provide a decent enough explanation, yes.
gollark: You would expect *some* other stargate network, since it was discovered... a few thousand years, or something, ~~since~~ before the present day in-setting and technology has improved since then.
gollark: And why hasn't someone else tried to/succeeded in figuring out the wormholes?
gollark: How is there *not* massive price gouging on the transit network anyway? I'm sure this was explained at some point, but I forgot the explanation, sooo...
gollark: The time loop thing does reduce the use a lot come to think of it, yes.
