Steven Weinberg is one of the world's pre-eminent theoretical physicists having won the Nobel Prize (shared with Abdus Salam and Sheldon Glashow) for their work on the standard model, which till date remains the best experimentally proved model of our universe. I had the pleasure of listening to him speak via video conferencing at last year's 50th anniversary celebration of The Abdus Salam International Centre for Theoretical Physics (ICTP) in Trieste, Italy where I am a student at present.
