This weekend we managed to catch the Sketches of Science exhibition at the Mondavi Center (also see the official website). I thoroughly recommend that people catch this free exhibition before it finishes on 28th January.
Photographer Volker Steger has met with many Nobel prize winners and asked them to make a poster (using crayons) that represents their nobel-prize-winning science. He then photographs them with their poster and some of the posters are also accompanied by audio interviews.
There is a lot of humor, beauty, and fun that emerges from this experience. Some scientists go for a simple representation of their work, others pack a lot into the poster (including a poem in one instance). Well worth seeing if you get a chance. I believe that this is the only place in the USA where this exhibit is being shown at the moment.
