I feel a bit guilty linking to a Canadian website, but this was very interesting and easy to understand and watch, despite being about quantum physics. Is matter made up of particles and waves, and why does observation determine which it behaves as?
I like things like this. It is so amazing that God could have created such a complex universe that even after countless millions of man-hours spent trying to understand it, the very basic nature of matter still eludes us.
Thanks, Ezra.
