How to think of 3x3 matrices as transforming 3d space

One might not think that snow could help anything stay warm through a harsh winter, but these tiny bats have found a way to utilize the insulation provided by the snow: they make little forts to wait out the winter.

Dr. Ivan Pavlov's groundbreaking work revealed that a dog will respond to neutral stimuli, such as a bell, in the same way that it will respond to, say, mouth-watering food. This research is widely applicable beyond a dog's salivation....

Physicist Werner Heisenberg said, "When I meet God, I am going to ask him two questions: why relativity? And why turbulence? I really believe he will have an answer for the first." As difficult as turbulence is to understand...

What does it look like when someone in Sweden brushes their teeth or when someone in Rwanda makes their bed? Anna Rosling Rönnlund wants all of us to find out, so she sent photographers to 264 homes in 50 countries (and counting!) to...

How counting in Ternary can solve a variant of the Tower's of Hanoi puzzle, and how this gives rise to a beautiful connection to Sierpinski's triangle.

The way your brain reacts to stimuli might tell us more about who you're friends with, and swatting at mosquitoes might one day bring us positive results.

Scientists just discovered the largest explosion ever detected, and it's thanks to the collaborative efforts of scientists from all over the world.

For you, going outside might mean a sunburn if you're out there too long without enough sunscreen, but for some people, any sun exposure can lead to hives and rashes within minutes!

Two proofs for the surface area of a sphere

We are constantly recognizing faces countless times a day, but how do our brains distinguish those faces so easily?

"The bends" is one of the biggest risks that humans have to deal with when diving, but why don't marine animals, which are diving all the time, get them?

Lots of life on Earth can fluoresce, creating a beautiful neon world of camouflage, communication, and adaptation that is hidden from the human eye.

SciShow Space News shares the latest developments from around the universe, including the discovery of water vapor on a new “exo-Neptune,” and cyanide found in the clouds where stars are born.

Hank explains speciation - the evolutionary process by which new biological species arise - in terms of finches, ligers, mules, and dogs.

Mr. Andersen explains the law of superposition and the principle of original horizontality. He uses an animation to explain how rock layers can accumulate over time.

What is torque? This is one of those things that you may have heard about in passing but never really understood. In this episode of Crash Course Physics, Shini sits down with us to discuss what torque is, how it works, why it works, and...

Our bones are multi-functional body builders, but perhaps their most mysterious function is the production of blood. Scientists now think they have a pretty good idea why this is where our blood gets made.

At SciShow, we ask the tough questions. Today we explore the answer to the question "if identical twin brothers married identical twin sisters, would their offspring be identical?"

Hank gets down to the nitty gritty about meiosis, the special type of cell division that is necessary for sexual reproduction in eukaryotic organisms.

We may be living IN a simulation (according to Elon Musk and many others), but that doesn't mean we don't need to perform simulations ourselves. Today, we're going to talk about good experimental design and how we can create controlled...

While many researchers are focusing on finding a difference in brains of people with dyslexia, some new research suggests it might not just be in their brains, but in their eyes.

It turns out this common phrase might have more of a basis in truth than you thought!
