I don’t usually write about personal interactions here, but this is one I couldn’t resist – physics superstar Lawrence Krauss talking cosmology with music superstar Peter Gabriel.

I was with Lawrence at a World Economic Forum dinner when he bumped into Peter – as one does!  He immediately launched into an animated discussion on the beginning and end of the universe, and everything else between, including the much-sought Higgs boson.

We all thought Lawrence just hadn’t got the foggiest who he was talking to.  But he admitted afterward that he was so over-awed, he just started talking – and carried on talking!

But the really cool bit – not only did Peter Gabriel graciously entertain the conversation; he was genuinely curious about what Lawrence had to say.

Very cool.

It was, as they say, a delicious Davos moment – and a science one at that!
