Today we’ll cover the fourth and final of our core disciplines of engineering: chemical engineering. We’ll talk about its history and evolution going from soda ash competitions to oil refineries and renewable energies. We’ll also discuss...

What do woolly pigs have to do with climate change? They're part of a vital, ingenious and evolving strategy to take carbon out of the sky and store it safely -- in trees, soils, the ocean, buildings, rocks and deep underground. Every...

Today we’re talking about mass transfer. It doesn’t just apply to objects and fluids as a whole, but also to the individual molecules and components that make them up. We’ll see that transfers of mass need their own driving force,...

From the sharp mouthparts of mosquitoes to the sticky feet of geckos, researchers have found all kinds of amazing adaptations in the natural world that could be useful in the operating room. Chapters WASPS & TISSUE EXTRACTORS 2:05...

The world's most entertaining and useless self-help guide, from the brilliant mind behind the wildly popular webcomic xkcd and the #1 New York Times bestsellers What If? and Thing Explainer For any task you might want to do, there's a...

MIT professor Neil Gershenfeld talks about his Fab Lab -- a low-cost lab that lets people build things they need using digital and analog tools. It's a simple idea with powerful results.

An atom smasher, or particle accelerator, collides atomic nuclei together at extremely high energies, using engineering that exploits incredibly cold temperatures, very low air pressure, and hyperbolically fast speeds. Don Lincoln...

An essential part of engineering is engineering design. Today we’ll see how design synthesis helps you put together the components of a process and decide what techniques are needed to solve your problem. We’ll explain the need test...

David Thouless, Duncan Haldane, and Michael Kosterlitz won the Nobel Prize in Physics in 2016 for discovering that even microscopic matter at the smallest scale can exhibit macroscopic properties and phases that are topological. But -...

Sending rockets into space requires sacrificing expensive equipment, burning massive amounts of fuel, and risking potential catastrophe. So in the space race of the 21st century, some engineers are abandoning rockets for something more...

Perpetual motion machines - devices that can do work indefinitely without any external energy source - have captured many inventors' imaginations because they could totally transform our relationship with energy. There's just one...

Get an engineeer's-eye-view of the tallest buildings in the world, to learn what challenges they face as they reach for the sky and wonder, how tall can we build?

Each of our bodies is utterly unique, which is a lovely thought until it comes to treating an illness -- when every body reacts differently, often unpredictably, to standard treatment. Tissue engineer Nina Tandon talks about a possible...

It's time for planetary-scale interventions to combat climate change -- and environmentalist Tim Flannery thinks seaweed can help. In a bold talk, he shares the epic carbon-capturing potential of seaweed, explaining how oceangoing...

Investigate the theories surrounding cosmic dust bunnies and discover how the tiny particles could hold the key to the formation of life on Earth. -- Consider the spot where you’re sitting. Travel backwards in time and it might’ve been...

Future advances in engineering may come from chemistry. From molecular motors to salt-shaker-drug-deliverers, the future looks small.

In January 1953, a tidal surge shook the North Sea. The titanic waves flooded the Dutch coastline, killing almost 2,000 people. 54 years later, a similar storm threatened the region. But this time, they were ready. This was thanks to a...

A plane fueled only by the sun is flying around the world and a certain cancer in shellfish is contagious! Olivia Gordon explains these stories in this week's SciShow News.

Chemist Lee Cronin is working on a 3D printer that, instead of objects, is able to print molecules. An exciting potential long-term application: printing your own medicine using chemical inks.

Linus Torvalds transformed technology twice -- first with the Linux kernel, which helps power the Internet, and again with Git, the source code management system used by developers worldwide. In a rare interview with TED Curator Chris...

Paul Andersen explains the importance of modeling in science and engineering. Models are used by scientists to explain phenomenon. Unlike mental models, conceptual models can be shared by all scientists to improve our understanding of...

Selecting which solution is the best solution to a problem may seem difficult at first. But if you are patient and think about what you need an effective solution to be, you can do it. In this episode of Crash Course Kids, Sabrina shows...

Robert Lang is a pioneer of the newest kind of origami -- using math and engineering principles to fold mind-blowingly intricate designs that are beautiful and, sometimes, very useful.
