Robert Alexander works to give the sun a voice. As a sonification specialist at the University of Michigan, Alexander turns data from the sun into music.

The discovery was the basis for the foundation of Norsk Hydro and the industrial bonanza at Notodden and Rjukan. Last, but not least: Birkeland was responsible for 60 new patents for everything from margarine and caviar to an elctromagnetic cannon. But most important from our perspective today is perhaps that he laid the foundation for much of the modern research conducted in the field of space and solar physics.
