How you can change the past
Forget particles and waves. When it comes to the true guise of material reality, what’s out there is beyond our grasp.

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
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.

The Science Of REAL Hoverboards
Hank gives it to you straight about “anti-gravity technology” — basically, it doesn’t exist. But if you really want to hover, you have options!
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.

Microscope: The Tube That Changed the World
Humans have long known that glass bends light. However, it took us awhile to figure out that stacking lenses in a tube would open up a whole new world to science, finally allowing us a peek at the microscopic.
Can You Escape The Force of Gravity?
It feels like you just can’t get away from clingy gravity. Even separated by distances of hundreds of millions of light years, gravity is reaching out to all of us. Is there a place you could go to get away from gravity entirely?

HOCKEY PUCK SQUISH (Real Time) under 82,000 lb Load
Remember that hockey puck I squished? Here’s the real time footage paired up with the displacement vs. force curve. You can see that it’s ripping apart internally at certain spots.
What gives, NSF??? (aka Science Funding: A Case Study)
In which I take on a recent decision by the United States National Science Foundation (NSF) that canceled funding for a continuation of the National Nanotechnology Infrastructure Network (NNIN). How am I in the know? I’m a user of the Cornell NanoScale Science & Technology Facility (CNF), a member of the previous incarnation of the NNIN.
