Animal Navigation Using Magnetic Fields
Picture this -- you're a worm. Yep, a worm. And not just any worm, a microscopic worm! How do you know where to go, or which way is up? And more importantly, why do we care? You'll find out in [...]
The Momentum of Swimming Dolphins
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 [...]
Exploring Position and Momentum in the Quantum World
Quantum physics is behind advances in digital cameras and cell phones, so it must also be able to explain the basics, right? Wrong. It turns out that classical physics doesn’t always work in the [...]
Kinematics, Impulse, and Human Running
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 [...]
Acceleration Isn’t Only Speeding Up
Sometimes you need to slow things down to figure out what’s going on. At a molecular level, slowing things down requires some pretty specialized equipment: lasers.
Mechanical Waves: Applications in Medicine
Researchers are making waves in an unlikely place: the human body. The reason? To detect and diagnose diseases.
Understanding Runaway Stars Using Newton’s Laws
Newton's laws don't only apply here on Earth. The most basic of physics principles are helping astronomers to understand strange phenomena lightyears away.
