We found this lovely piece of street art under the bridge over the Thames on the southern by-pass in Oxford. Einstein is such an iconic figure - but I like the phrase "Einstein isn't the only physicist" that I got from a poster in my laboratory. One of the most important living physicist is Leonard Susskind who was a founder of String Theory. He has done a brilliant service in giving public lectures at Stanford University and posting them on the Internet for us all to watch. I have started watching the ones on Einstein's General Theory of Relativity. They are all nearly 2 hours long so I'm going to watch them in bits: http://theoreticalminimum.com/courses
