Wave–Particle duality is an interesting concept to think about. Did you know that in 1906 Joseph John Thomson received the Nobel Prize for proving that electrons are particles. And, that his son, George Paget Thomson, in 1937 was awarded the Nobel Prize for proving that electrons are waves. And both descriptions correctly describe light.
For some this is a paradox. What do you think? This is a Open Thread / Coffee Hour. So, what are you thinking about? What is for dinner? And, how are you today?
