THE THINGS YOU DON'T UNDERSTAND, 2010, Peter and Petra Lataster Mathematician Hendrik Lenstra has no car, no computer and no television. But he is the proud owner of numerous editions of Homer’s Odyssey. Directors Petra & Peter Lataster draw a portrait of Lenstra, a mathematician who thinks on the highest level. And also in daily life he is not interested in the superfluous and the fashionable. http://www.latasterfilms.nl/en/films/the-things-you-dont-understand/
