The answer to this question has everything to do with drag & kinetic energy vs momentum change (thrust) ie, a bigger engine fan allows for a larger air mass to be accelerated a smaller amount to give the same thrust as you'd get from a...

How is the chemical energy of gasoline transformed into kinetic energy of a moving car? And where does that kinetic energy go when the car crashes into something and stops moving?

How Do Airplanes Fly?

Ada Lovelace, Daughter of Lord Byron, was somehow the first author of a computer program...even though she lived more than a century before the first modern computer.

In 1962, John Glenn went into orbit on an Atlas rocket, and thus began a family of rockets that lasted for 60 years!

Surveyor 6 may not have been the first craft to make a soft landing on the Moon, but it is the first craft to take off from the surface of another world. And it did so in a very adorable way. Long before any Apollo astronaut, Surveyor 6...

The Kepler telescope recently noticed a strange partial eclipse that some have speculated could be a Dyson Sphere. Are Dyson Sphere's possible? Are they practical? What other alternatives to futuristic energy capture do we have to choose...

Early this year, 3D printing showed off its space-age technology capabilities by printing most of a rocket that was launched into space.

Units are a major way we describe the world around us, and by looking at the scientists some of them are named after, we can get a sense of how we’ve learned so much about our universe.

How does heat affect airplanes? Turns out heat, speed and density connect to create dangerous situations.

Lead is really useful when you add it to things like paint and gasoline. Problem is, it’s also poisonous. Hosted by: Hank Green

Are you slowly killing your car by using below average gas? Olivia talks about octane ratings and how your vehicle is designed to handle them. Hosted by: Olivia Gordon

As Squeaks continues to prepare for his big trip on a plane, he and Jessi learn the science behind how airplanes fly!

Sen. Duckworth Writes Of Resiliency, Healing In Her Book That Is A ‘Love Letter’ To America

The physics of the perfect storm

This week we’re exploring aerospace engineering and its two main fields: aeronautical engineering and astronautical engineering. We’ll explore life & buoyancy, propulsion systems, and the challenges of managing the human body in space.

How Do Airplanes Fly?

Chemical engines can only move us through the solar system so quickly, but a faster method is being engineered right now that could get us to Mars in just 40 days!

The answer to this question has everything to do with drag & kinetic energy vs momentum change (thrust) ie, a bigger engine fan allows for a larger air mass to be accelerated a smaller amount to give the same thrust as you'd get from a...

In 2010, technologist Tan Le took the TEDGlobal stage to demo a powerful new interface. But now, at TEDxWomen, she tells a very personal story: the story of her family -- mother, grandmother and sister -- fleeing Vietnam and building a...

Today we continue our tour through the major fields of engineering with a look at mechanical engineering, beginning with the steam engine. We’ll discuss aircraft, the development of aerospace engineering, and take a look into the future...

There are over one billion cars in the world right now, getting people from point A to point B. But cars aren't just a mode of transportation; they also teach an excellent lesson in chemistry. Cynthia Chubbuck navigates the intricate...

Hank takes on the role of our personal space travel agent, giving us the dirt on the various ways in which the exceptionally wealthy will be able to travel to space in the next few decades.
