Laurence Krauss

I'm behind on blogging about what we have done, so here begins some catching up. On the 12th we went to Town Hall to hear a lecture by Laurence Krauss. He gave an entertaining presentation tying big ideas in physics together very nicely.

His unifying notion was how significant steps forward in physics encompassed previous ideas in a larger, more general idea. From the shadows on the wall in Plato's two dimensional representation of the world to the quantum fields we see around us in the world, each step includes the previous steps as a subset, an approximation, a limited view of the world. It was a good story, even if it was one that I know the pieces of. It was told in a new and fun way.

Of course, there was some politics thrown in there as well, as one expects from him. All in all, a good evening.
