The events leading to the discovery of tunnelling supercurrents took place while I was working as a research student at the Royal Society Mond Laboratory, Cambridge, under the supervision of Professor Brian Pippard.

I read a book called 'The Tao of Physics' by Fritjof Capra that pointed out the parallels between quantum physics and eastern mysticism. I started to feel there was more to reality than conventional science allowed for and some interesting ideas that it hadn't got round to investigating, such as altered states of consciousness.

It's not clear in physics why you can't see the future.
