Is There Intelligent Life Beyond Earth?
Now that we know planets are common in our galaxy, how would we tell if one holds life? Sure, it will take incredibly powerful telescopes and ambitious new space missions, but what are we looking for? What are we listening for? How do we...

Can We Predict An Outbreak's Future? - Modeling: Crash Course Outbreak Science
When outbreaks happen, we need to be able to predict the course they’ll take in the future, but of course we can’t run experiments on real people to figure that out. Thankfully we can simulate outbreaks and use models to find out how...

Kinetic Energy
In this video Paul Andersen explains how the kinetic energy of an object if due to the motion of an object. Objects can have kinetic energy but they cannot have potential energy unless they are part of a system. He then explains how to...

Chi-squared Test
Paul Andersen shows you how to calculate the ch-squared value to test your null hypothesis. He explains the importance of the critical value and defines the degrees of freedom. He also leaves you with a problem related to the animal...

The Reaction Path
In this video Paul Andersen explains how the reaction path can be described in an energy profile. Enough energy must be added to reach the activation energy required and stress the bonds. Eventually the bonds break and new bonds are...

Average Value of the Electric Field
In this video Paul Andersen explains how the average value of the electric field can be determined by dividing the potential difference by the displacement. Equipotential lines can be used to determine the potential in an electric field...
