Ljushastigheten

I "Thinking Physics is Gedanken Physics" står beskrivet hur Römer utnyttjade Jupiters månar för att bestämma ljushastigheten.

Kommentarer om ljushastighetens tidsberoende

A student project in 1997 considered the possible time variation of the speed of light, based on a paper by Norman and Setterfield, who discuss the possibility that the speed of light has decreased over the years. A summary is available on-line Since this has been brought up in the students' project, I tried to collect various links to the discussion following this paper. The reading gives you a good chance to practice "balance between critique and accept", but is not recommended as the focus of the project work!
