When you hear the word symmetry, you might think generally of triangles, butterflies, or even ballerinas. But defined scientifically, symmetry is _a transformation that leaves an object unchanged." Huh? Colm Kelleher unpacks this...

There was physics before Einstein in the same way that there was biology before Darwin. Einstein didn’t just add some new ideas to physics. And he didn’t just add a unifying framework for doing physics, like Newton. Einstein took what...

The study of electricity goes all the way back to antiquity. But, by the time electricity started to become more well known, a few familiar names started to appear. Edison, Galvani, and a few others really changed the way the world worked.

A bit of the history behind how we came to use the symbol "pi" to represent what it does today, and how Euler used it to refer to several different circle constants.

What is matter, anyway? What does it have to do with math? And why aren't you made of Jesus? Delving deeper into the theory of (almost) everything - the Standard Model of particle physics.

Today we're going to introduce bayesian statistics and discuss how this new approach to statistics has revolutionized the field from artificial intelligence and clinical trials to how your computer filters spam! We'll also discuss the...

How the heck do we map out a planet without oceans? NASA had to figure that out when we sent the Mariner 9 probe to Mars. There's some tricky, yet fascinating science behind all of it! In this episode of Crash Course Physics, Shini talks...

SciShow explains how some great, Nobel-winning research into the human brain turned into a meme of misunderstanding that lasted for decades.

There are aspects of computer code that look like language and some that seem more like algebra, and since we may be headed for a future where many people will need to learn to code, researchers are interested in figuring out how exactly...

After a friend of mine got a tattoo with a representation of the cosecant function, it got me thinking about how there's another sense in which this function is a tattoo on math, so to speak.

John Maeda, former President of the Rhode Island School of Design, delivers a funny and charming talk that spans a lifetime of work in art, design and technology, concluding with a picture of creative leadership in the future. Watch for...

Could we have a possible 9th Planet? Hank Green tells us what we think we know with this elusive object.

It's your first day at Magnificent Marigold's Magical Macademy. But before you can learn your first spell you must get through the sorting ceremony. And the sorting hat has chosen you for a special challenge. The Macademy had 8 founders...

What are limits? How are they defined? How are they used to define the derivative? What is L'Hospital's rule?

How to think about implicit differentiation in terms of functions with multiple inputs, and tiny nudges to those inputs.

Math is invisible. Unlike physics, chemistry, and biology we can't see it, smell it, or even directly observe it in the universe. And so that has made a lot of really smart people ask, does it actually even EXIST?!?!

Consider the following sentence: "This statement is false." Is that true? If so, that would make the statement false. But if it's false, then the statement is true. This sentence creates an unsolvable paradox; if it's not true and it's...

Adam Savage walks through two spectacular examples of profound scientific discoveries that came from simple, creative methods anyone could have followed -- Eratosthenes' calculation of the Earth's circumference around 200 BC and...

Once every century, the world's greatest spiders gather to compete in a series of grueling games. The winner will become the next arachnomonarch, able to command all the world's spiders to their will. That day is today, and for the first...

On Olympus, you've been waiting for an opportunity to bring the bloody Trojan War to its conclusion. The two sides have agreed to a brief truce, and when you consult the Fates, they advise: should the peace last for 10 days, all will end...

Historically speaking, there is no one scientific method. There's more than one way to make knowledge. In this episode we're going to look at a few of those ways and how they became more of the "norm."

Open Letter to the President - Physics Education

Two perfectly rational gingerbread men, Crispy and Chewy, are out strolling when they're caught by a fox. Instead of simply eating them, he decides to put their friendship to the test with a cruel dilemma. He'll ask each gingerbread man...

New ReviewWhat a cool math science trick!
