On the 8th of July we had lab day at EMBL. With the Erzberger group we prepared some games to illustrate physical principles that underlie biological phenomena. We had a game involving surface tension and floating paperclips, a game with pattern formation and a computer game designed to illustrate what life is like at high and low Reynolds numbers. In this game you play either as a whale or as a bacterium, whose motion is dominated by inertia and friction respectively. The goal was to catch the lab members while avoiding being caught by a swimming Osborne Reynolds.
