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

In the early days of the space race, agency researchers in Russia and at NASA really weren't sure all what would happen to an astronaut in space. They didn't know if a human mind could handle actually seeing Earth or what would happen to...

Water is one of the most abundant and important substances on Earth, so you think we'd know everything there is to know about it. Turns out, water is so much stranger and more complex than we ever thought! Join Olivia Gordon for a new...

New information has helped us understand where domestic horses came from. And by counting some tree rings, researchers were able to find evidence of Norse presence in the Americas in 1021 CE.

The equator is a clear and accurate line around Earth that makes measuring latitude a precise science, but when it came to figuring out how to do that with longitude, British sailors were at a loss. Until they devised a competition....

If you take a look at a map of Scotland, you'll notice an eerily straight line running through the highlands, this is the Great Glen Fault the product of half a billion years of time and geology.

Modern life runs on wireless technology. What if the energy powering our devices could also be transmitted without wires? Electrical engineer Ali Hajimiri explains the principles behind wireless energy transfer and shares his far-out...

In all the conversations about improving education for children, the voices of students, teachers and community members are often left out. Educational designer Punya Mishra offers a method to shift that paradigm, taking us through new...

Fasten your seat belt as software engineer Alex Koster takes us on a journey in what he calls the "software dream car" of the future. He breaks down how massive technological shifts are transforming the automotive industry and paints a...

Several crises are set to define the next century -- but journalist Aaron Bastani believes we have the technological ability to meet our biggest challenges and create unprecedented levels of prosperity for all. He shows how we could get...

Architecture can't ignore the realities of climate change. For time-tested solutions that perform under extreme conditions, designer Alyssa-Amor Gibbons says we should look to traditional buildings. Taking us to her home of Barbados,...

Climate justice activist Vanessa Nakate sits down with former president of Ireland Mary Robinson for an enlightening, intergenerational conversation about the state of the climate crisis. Nakate paints a picture of life in her home...

Some see string theory as the one great hope for a theory of everything - that it will unite quantum mechanics and gravity and so unify all of physics into one glorious theory.

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.

In this video Paul Andersen explains how atoms are conserved in a chemical reaction. This can be seen in a chemical equation where the subscripts represent the atoms in the molecule and the coefficients represent the molecules. The...

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

An introduction to an interactive experience on why quaternions describe 3d rotations

Higher dimensional spheres, or hyperspheres, are counter-intuitive and almost impossible to visualize. Mathematician Kelsey Houston-Edwards explains higher dimensional spheres and how recent revelations in sphere packing have exposed...

Moser's circle problem, and its solution.

Using geometry we can not only understand, but visualize how causality dictates the order of events in our universe.

The third and final part of the block collision sequence.
