Chemistry is the study of matter - stuff, and how it interacts with other stuff. Even though chemistry doesn't make a lot of news these days, chemists are making discoveries that change lives all the time. If Hank had to narrow down all...

Learn about how one Japanese startup wants to offer meteor showers on demand, and how this will affect our scientific study of the mesosphere.

Paul Andersen explains how populations experience exponential. He begins by address the major players; N (population size) and r (growth rate). He models population growth in rabbits through four generations. He then shows you how to...

Any molecular biologist will tell you that genetic engineering is tricky. But up until recently we might be witnessing a new age in human development.

In this, THE FIRST EPISODE of Crash Course Physics, your host Dr. Shini Somara introduces us to the ideas of motion in a straight line. She talks about displacement, acceleration, time, velocity, and the definition of acceleration. Also,...

How do we comprehend a storm like Hurricane Harvey? Let's put it into perspective.

In this video Paul Andersen explains how equipotential lines show equal electric potential in an electric field. Equipotential lines can be created from scalar values or by observing the electric field lines. An charged object can move...
