Snake Locomotion

The video explores the fascinating question of how snakes move without legs, focusing on the role of their scales. Mathematician David Hu explains that snake scales are smooth to reduce forward friction but rough when rubbed in the opposite direction, aiding movement. This design is similar to ice skates, which slide easily forward but catch when pushed sideways. Hu's team created a jacket to test this, showing that scales are crucial for movement. Mathematical models incorporating weight redistribution further explain snake slithering, drawing parallels to human walking. The research highlights the unique challenges and discoveries in understanding snake locomotion.
