When I think space stuff, I think solid, steady masses moving in organized orbits and rotations. But it turns out, they wobble! Isn't that kind of cute to think of a wobbling planet? Just me? [...]
How do you design a robot that can swim efficiently under water? Scientists are studying the physics behind dolphin movement for the answer! (And if you're wondering why scientists are [...]
What separates the gold medal sprinters from the casual weekend jogger...besides the intense training, of course? Thanks to a careful analysis of human runners and good old-fashioned physics, we [...]
