We don't want to deluge you with information on the subject, but this week on Crash Course Mythology, Mike Rugnetta is talking once again about floods. We're looking at ancient flood myths in the Americas, and what they can tell us about...

What will become of humanity after spend a few hundred years on Mars? What will happen after a few thousand? Evolution has, and still is, shaping humanity in rather drastic ways. How long will humans stop being human and become Martian?

Isaac Newton's Universal Law of Gravitation tells us that there is a singularity to be found within a black hole, but scientists and mathematicians have found a number of issues with Newton's equations. They don't always accurately...

What is the dot product? What does it represent? Why does it have the formula that it does? All this is explained visually.

Have a problem with many competing variables? Why not solve it with a computer algorithm based on cooling metal?

Mr. Andersen describes the virtual fly lab. Software at sciencecourseware.org allows for multiple matings and statistical analysis.

Could it be that all the electrons in the universe are simply one, single electron moving back and forth through time?

In this episode of Crash Course Psychology, Hank walks us through the troubling world of Eating and Body Dysmorphic disorders. There's a lot going on here and, even though we still have a lot of dots to connect, a lot we can learn...

We here at SciShow compiled a list of videos based on popular requests. Hank Green hosts with this winter themed episode!

What is the dot product? What does it represent? Why does it have the formula that it does? All this is explained visually.

There's a compound found in squid skin that they use to change color and protect their cells, but it could also help us fight some of the most common disease-causing microbes out there.

In this video Paul Andersen explains how scalar fields can be used to show the distribution of scalar quantities. The most important scalar fields in AP Physics 2 deal with electric potential. Scalar addition can be used to combine...

You may have heard about a study where researchers were able to grow lumps of neural tissue that showed measurable activity – a little bit like an actual brain. Are scientists trying to grow artificial brains, and if so, what kind of...

Worried about black holes? Consider this: Every time you accelerate - you generate an event horizon behind you. The more you accelerate away from it the closer it gets. Don't worry, it can never catch up to you, but the Unruh radiation...

Black holes have mystified physicists for decades, but with the help of quantum mechanics, we are beginning to make serious progress in understanding these strange objects. This week on Space Time, Matt dives deeper into the physical...

An overview of gradient descent in the context of neural networks. This is a method used widely throughout machine learning for optimizing how a computer performs on certain tasks.

Solving a discrete math puzzle, namely the stolen necklace problem, using topology, namely the Borsuk Ulam theorem

Today, we're going to step away from video games and take a closer look at a game type that has been with us for over a millennium - card games. Since Tang Dynasty China, cards have proven to have quite the staying power spawning a...

Seasonal illnesses from infectious diseases aren’t a new concept, but a few decades ago public health experts began to notice the same behavior in some non-infectious diseases like breast cancer. These patterns have helped us learn a lot...

The formula for the cross product can feel like a mystery, or some kind of crazy coincidence. But it isn't. There is a fundamental connection between the cross product and determinants.

Why are Stars Star-Shaped

A visual for derivatives which generalizes more nicely to topics beyond calculus. Thinking of a function as a transformation, the derivative measure how much that function locally stretches or squishes a given region.

By choosing the right path and the right reference frames, any superluminal motion can lead to information or objects returning to their origin before they depart.
