Professor Brian Cox and I have always enjoyed teasing Deepak. We call his chatter “The Quantum of Bollocks,” for he manages to mix cosmology and bullshit. “There are no extra pieces in the Universe. Everyone is here because he or she has a place to fill, and every piece must fit itself into the big jigsaw puzzle.” So much for physics. Brian is kinder than me, but Deepak’s form of quasi-scientific religiosity gets to him too.
