1 week agoWhy ice skating is a miracle of physics
Imagine there's a large, flat sheet of ice out in front of you, and someone unceremoniously shoves you across it at a high speed. What are you to do? If you're wearing conventional shoes, without crampons or blades attached to them, you're going to have a difficult time. Ice is a very low-friction surface, and there's very little you're going to be able to do to change your momentum without slipping and perhaps falling down.
