  In this paper, we teach a machine to discover the laws of physics from video
streams. We assume no prior knowledge of physics, beyond a temporal stream of
bounding boxes. The problem is very difficult because a machine must learn not
only a governing equation (e.g. projectile motion) but also the existence of
governing parameters (e.g. velocities). We evaluate our ability to discover
physical laws on videos of elementary physical phenomena, such as projectile
motion or circular motion. These elementary tasks have textbook governing
equations and enable ground truth verification of our approach.
