My recollection of the higher school certificate, which involved a practical exam in physics, was being confronted with an experiment involving a sort of barometer arrangement, wondering why I couldn't make it work.

Nobody else took what I was doing seriously, so nobody would want to work with me. I was thought to be a bit eccentric and maybe cranky.

The model I came up with in 1964 is just the invention of a rather strange sort of medium that looks the same in all directions and produces a kind of refraction that is a little bit more complicated than that of light in glass or water.

When you look at a vacuum in a quantum theory of fields, it isn't exactly nothing.

There is a sort of mythology that grows up about what happened, which is different from what really did happen.

I was an embarrassment to the department when they did research assessment exercises. A message would go round the department: 'Please give a list of your recent publications.' And I would send back a statement: 'None.'
