Hank describes how non-Newtonian fluids can save lives - and dreams of a bulletproof hoodie.

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.

How to think about matrix multiplication visually as successively applying two different linear transformations.

Hank describes how non-Newtonian fluids can save lives - and dreams of a bulletproof hoodie.

You might have clothes, like a hat or a warm, cozy sweater, that are made of wool. You might even know that a lot of wool comes from sheep! But do you know how wool goes from growing on a sheep to being made into a sweater?

A horseshoe vortex cloud is an odd kind of cumulus cloud that is usually small and brief, so it goes unnoticed. It’s shaped like a horseshoe. Some sort of up and down air motion or spin in the air, known as a vortex, creates these, but...

Pupil outcome: I can write an excellent narrative using an emotion-led plot and detailed descriptions. Key learning points: - Narratives that try to tell too much story are often unsuccessful - Using an emotion-led narrative will help...

Slime is all the rage with kids these days. One common form of slime is known as Oobleck. Oobleck happens to be a non-Newtonian fluid. Join Dr. Boyd in making Oobleck, and learning what it means to be a non-Newtonian fluid. Minute 0:30 –...

This material, inspired by gecko skin, has the unique ability to stick to smooth surfaces like fruits, water bottles, and bags without being sticky. Developed in Professor Mark Kokuski's lab at Stanford, it mimics the van der Waals...

Have you ever seen clouds that look like ocean waves? Sometimes wavy clouds mix in with other clouds and you don’t notice. Other times they stand out, but may not last very long. Clouds that look like waves on the ocean have a name of...

Over a thousand tornadoes happen every year in the United States but only few dozen take lives. Most tornadoes are brief and weak but the tornadoes that are large and powerful can wipe homes off their foundations. Tornadoes only come...

Understanding what happens at the epicenter of an earthquake, as the tectonic plates beneath the earth shift and the earth shakes, could help us better predict when and where the next big one will hit. For the past six years scientists...

It’s no surprise that forces are everywhere! But how do we work out which forces are important, and which ones can be ignored? This lesson will distinguish between external and internal forces, before diving into more examples of contact...

This video provides an explanation of plane stress, which occurs when all of the stresses acting on a component are in the same plane. The two types of stress, normal stress and shear stress, are introduced, along with their...

This video explains the concepts of shear stress and torsion. It describes how internal stresses develop in a beam to resist external forces and how shear stress is defined as force per unit area when the force is acting parallel to the...
