Eric Edlund (1819-1888) investigated fluid motion, polarization of light during a total eclipse, and thermal phenomena accompanying changes in volume of solids. He studied electricity, describing a method of simultaneously transmitting messages in opposite directions along the same telegraph wire. He investigated the heat given off by induction currents. He studied electromotive forces generated when two different metals are put in contact. He investigated the resistance of arc lamps. He developed a theory of atmospheric electricity to explain the phenomenon of the northern lights. For the 1995 film, see Total Eclipse (film). ... Lightning strikes during a night-time thunderstorm. ... Northern Lights is a common name for the polar aurorae in the northern hemisphere. ...
He obtained his PhD in physics in 1845 at Uppsala University under Svanberg. Edlund then worked under Weber in Leipzig for two years after obtaining his PhD.
Edlund is notable as the doctoral advisor of Svante Arrhenius. Svante August Arrhenius (February 19, 1859 – October 2, 1927) was a Swedish chemist and one of the founders of the science of physical chemistry. ...
