Craig Callender is a philosopher of science who has been interested in time and space his whole life. He believes that they are the two greatest mysteries in science. With artist Ralph Edney, he wrote a cartoon book Introducing Time: A Graphic Guide that traces our understanding of time through history. His book What Makes Time Special? tries to reconcile our experience of time with the physics of time. It won the 2018 Lakatos Award and the 2022 Patrick Suppes Prize. Craig works in the Department of Philosophy at the University of California, San Diego, where he is also a Director of the Institute for Practical Ethics. When he is not working, he is often paddling up and down the San Diego coastline looking for interesting marine life.
