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.
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 this lesson.
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 quantum world.
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 now have a pretty good idea.
Space is big. (duh). So big that getting anywhere close to even our solar system’s nearest neighbors seems impossible. But what if we told you that you that researchers have a plan to make light-speed space exploration a reality? One-way trip to Proxima Centauri, anyone?
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 designing robots that can swim efficiently under water… this lesson covers that, too.)
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.
