This spring, I did a guest lecture for a science communication course in which I asked the graduate students in the class to draw their research. I was inspired by Sketches of Science, a traveling exhibition of photographs of Nobel Laureates with their drawings.
Just for fun, I drew mine as well. I found this five minute sketch helped me distill the ideas floating around in my head. When I was finished, I could explain the main argument of my book more simply and clearly than I ever had before.
