From Gerry Stern
Your look at the search for the next breakthrough in physics was outstanding (2 March, p 37). I had just read Lawrence Krauss’s book on cosmic origins, A Universe From Nothing, and your special issue was a great wrap-up. The diagram of the standard models of particle physics and cosmology on a timescale was the icing on the cake; I’d hang a big copy on my wall.
