In this short, provocative talk, architect Alison Killing looks at buildings where death and dying happen -- cemeteries, hospitals, homes. The way we die is changing, and the way we build for dying ... well, maybe that should too. It's a...

Stretching 227 meters tall, two towers were assembled to support California's Golden Gate Bridge. They were just one of the challenges facing engineers Charles Ellis and Joseph Strauss. Even before construction began, many thought the...

Modern buildings with floor-to-ceiling windows give spectacular views, but they require a lot of energy to cool. Doris Kim Sung works with thermo-bimetals, smart materials that act more like human skin, dynamically and responsively, and...

Author Sam Martin shares photos of a quirky world hobby that's trending with the XY set: "manspaces." (They're custom-built hangouts where a man can claim a bit of his own territory to work, relax, be himself.) Grab a cold one and enjoy.

The James Webb Space Telescope is the most complex telescope we’ve ever sent into space. But, Webb is not, in fact, in space… yet.

Long before sustainability was a buzzword, architect Shigeru Ban was using ecologically sound building materials such as cardboard tubes. He uses them to build remarkable temporary structures for disaster-struck nations such as Haiti,...

In this episode of Crash Course Film History, we talk about the development of the language of films by filmmakers like Edwin S. Porter and his films; Life of an American Fireman and The Great Train Robbery.

Architecture is more than a clever arrangement of bricks. In this eloquent talk, Michael Murphy shows how he and his team look far beyond the blueprint when they're designing. Considering factors from airflow to light, theirs is a...

If we hope to someday live on other worlds we need to figure out where we’re gonna lay our heads at “night.” But who would have thought we could use our own bodies as ingredients for our homes?!

Sci-fi technology is often more fiction than science, but it turns out there are actually some real-world labs that are working on developing force fields!

Things can go wrong in scientific experiments sometimes, but when it comes to engineering, getting things wrong can be disastrous.

Hank talks about the molecules that make up every living thing - carbohydrates, lipids, and proteins - and how we find them in our environment and in the food that we eat.

In the 19th century, the California gold rush brought thousands of settlers to America's west coast. But finding gold may have been easier than transporting it back east. The only hope for avoiding a grueling six month wagon journey was...

In 1978, Diane Hartley was writing her undergraduate architecture thesis when she made a shocking discovery. After weeks of poring over the Citicorp Center's building plans, she'd stumbled on an oversight that threatened to topple the...

The band OK Go dreamed up the idea of a massive Rube Goldberg machine for their next music video -- and Adam Sadowsky's team was charged with building it. He tells the story of the effort and engineering behind their labyrinthine...

In this video Paul Andersen explains why atoms in the periodic table show trends in ionization energy, atomic radii, electronegativity and charge. All of these trends are explained through Coulomb's Law. A brief description of Dmitri...

Concrete is responsible for 8% of humanity’s carbon emissions because making its key ingredient - cement - chemically releases CO2, and because we burn fossil fuels to make it...

Using robotics, laser rangefinders, GPS and smart feedback tools, Dennis Hong is building a car for drivers who are blind. It's not a "self-driving" car, he's careful to note, but a car in which a non-sighted driver can determine speed,...

It is time to close the funding gap for Black female-led start-ups the world over, says entrepreneur Temie Giwa-Tubosun, whose company LifeBank delivers life-saving medical supplies to remote areas in Africa. Today, LifeBank operates...

Hank talks about Renaissance architect, engineer, and professional cranky guy Filippo Brunelleschi in this "Great Minds" dose.

Concrete sucks CO2 out of the atmosphere, but making it initially produces a lot of carbon dioxide as a byproduct. Fortunately, by rethinking the chemistry of cement altogether, we can actually use carbon dioxide to create our concrete...

What if you were on a high floor of a skyscraper and the building started swaying? Today we’ll explore statics and dynamics, and what they mean for the structures we design. We look at the idea of static equilibrium, forces, and torques,...

Bill and Webb want to reach a button that is really high up on the wall, so Mister Brown teaches them how to use engineering and teamwork to make a high up button pusher!
