The very energetic and interesting Dr. Helen Czerski presented “We need to Talk about Physics” at today’s meeting of Oxford Skeptics in the Pub. We learnt why blueberry jam isn’t blue; why the Hubble telescope is like a raw egg; and why there is a lot of physics still to do to understand everyday phenomena (such as how bubbles move in a turbulent fluid.)
I’m afraid the likeness is worse than usual. Dr. Czerski doesn’t do standing still.
