It's football season so along with cheers and yelling you will hear a more dangerous sound; the sharp crack of helmet-to-helmet collisions. Hard collisions can lead to player concussions but the physics of how the impact of a helmet hit transfers to the brain is not yet well understood. A research team has created a simplified experimental model of the brain and skull inside a helmet during a helmet-to-helmet collision. The model illustrates how the fast vibrational motion of the hit translates into a sloshing motion of the brain inside the skull. read more
