The fundamentals of space-time: Part 1 - Andrew Pontzen and Tom Whyntie

Space is where things happen. Time is when things happen. And sometimes, in order to really look at the universe, you need to take those two concepts and mash them together. In this first lesson of a three-part series on space-time, hilarious hosts Andrew Pontzen and Tom Whyntie go through the basics of space and time individually, and use a flip book to illustrate how we can begin to look at them together.

Nothing Is The Color You Think It Is. Or Is It?

Color is a very interesting thing, just about everything has one. Though, what I am doing today is tackling the idea behind what color is and what is what color. It might be more surprising than you think.

Try mixing your own colors with light:

Astronomy Cast: Wernher von Braun

When the United States helped defeat Germany at the end of World War II, they acquired the German rocket scientist Wernher von Braun. He had already developed the German V2 rocket program, and went on to design all the major hardware of the US rocket program. This week, we talk about von Braun’s life and accomplishments.

The Science of Dust

via jtotheizzoe:

Wanna get dirty with me?

From star stuff to microscopic fluff to skin cells that slough while you’re in the buff, the universe of dust is curious enough to turn your mind into a cream puff.

May this week’s episode spread like dust on the wind.

Is This the Future of Alternative Wind Energy?

The makers of Buoyant Airborne Turbine (BAT) think they’ve got the next step in alternative wind energy, without the large grounded turbines. The BAT is a high-altitude mobile wind-powered generator, that’s able to convert the more powerful wind currents into a substantial amount of electricity. It can also hoist cellular transmitters and meteroological equipment.

It sounds great, but the BAT isn’t perfect…right? Kim Horcher, Tim Frisch, and Christina Ochoa (Scirens, Chaotic Awesome) discuss!

Understanding Crystallography №2 From Crystals to Diamond

How do X-rays help us uncover the molecular basis of life?

In the second part of this mini-series, Professor Stephen Curry takes us on a journey into the Diamond Light Source, one of the UK’s most expensive and sophisticated scientific facilities.

Generating light brighter than the sun, and hosting a particle accelerator, Diamond is often used to determine the structure of complex molecules. By placing crystalline samples of proteins in the powerful beams of X-rays, scientists can use the data obatined from the generated diffraction patterns to model accurate 3D structures of the protein molecules.

Professor Curry explores the inner workings of the Diamond Light Source to reveal how such facilities are aiding the field of structural biology and continuing the work of the early crystallography pioneers 100 years on.

Bill Nye Explains Magnetism and How Magnets Work

A fan wants an explanation of magnets and magnetism, but little did he know his Cosmic Query would be answered by none other than Bill Nye the Science Guy. Bill was our guest host for this episode, along with guest NASA astronaut Mike Massimino and comic co-host Eugene Mirman. Find out how Earth’s magnetic field arises and helps protect our atmosphere, and why Mars’ lack of magnetic field contributed to its loss of atmosphere. You’ll hear about MAVEN, Michael Faraday, Eugene’s plan to terraform other planets and… Insane Clown Posse?

Cowboy Physics: The Math of Trick-Roping

Two animated clips from a trick-roping model show what happens to a lasso when changing either the size of the loop or the rotation speed is changed. A trick roper demonstrates these skills in real life.
