Retired Electrical Engineer. After following a MOOC from Duke University (Introduction to Astronomy), a series of Lectures by Pr Suskind of Standford Univ and a series of Lectures from Heaerus Winter School on Gravity and Light, I carry on studying most aspects of SR and GR and their mathematics basis. The StackExchange forum is a great source of information on all these topics.
