On April 29th, 2013, Doug was invited to give a talk at Princeton University by Professor Manjul Bhargava of the math department. The seminar consisted of a select group of freshman studying the mathematics of magic tricks and games. Doug demonstrated a few effects and discussed how mathematics was used in the construction of his routine and the various strategies he used to hide the mathematical methods. The students were extremely inquisitive with many staying late in order to delve deeper into the subject matter.
