Project Loon - Google's Internet Balloons - Future Thinking - Head Squeeze
AdultsInternet CulturePhysicsTechnology...We are becoming increasingly more dependent on the internet to help run our lives. But much of the planet is outside the web, zones that are without web coverage. Ordinarily, this is more of a nuisance than a calamity. But in the aftermath of disasters, restoring internet coverage can be the difference between life and death.
The fundamentals of space-time: Part 2 - Andrew Pontzen and Tom Whyntie
AdultsMathPhysicsScience...Light always travels at a speed of 299,792,458 meters per second. But if you're in motion too, you're going to perceive it as traveling even faster -- which isn't possible! In this second installment of a three-part series on space-time, CERN scientists Andrew Pontzen and Tom Whyntie use a space-time diagram to analyze the sometimes confounding motion of light.
There's No Such Thing As Cold
AdultsPhysicsWeatherScience...You've felt cold before. Sometimes it's cold outside. But what if I told you that "cold" isn't real? There's no substance or quantity called "cold" in science. We can't measure the amount of "cold" in something. Instead it's about what's NOT there. In this week's video, learn the difference between heat and temperature, why a wind makes us feel colder, and what it's like to live as a mass of jiggling atoms. This is the physics of cold.
Quantum Entanglement & Spooky Action at a Distance
AdultsPhysicsScienceTechnologyDoes quantum entanglement make faster-than-light communication possible?
Sparks from Falling Water: Kelvin's Thunderstorm
AdultsPhysicsTechnologyScience...The physics behind Kelvin's Thunderstorm explained. No, it is not a practical way of generating electricity, which is why we use turbines at hydro stations.
Why Does Time Go Forward?
AdultsFuturePhilosophyScience...The past is different from the future. Why?
How many universes are there?
AdultsScienceSpacePhysics...The fact that no one knows the answer to this question is what makes it exciting. The story of physics has been one of an ever-expanding understanding of the sheer scale of reality, to the point where physicists are now postulating that there may be far more universes than just our own. Chris Anderson explores the thrilling implications of this idea.
Why Van Gogh's "Starry Night" Is Actually An Art Of Science
AdultsArtSciencePhysicsPhysicist Werner Heisenberg said, "When I meet God, I am going to ask him two questions: why relativity? And why turbulence? I really believe he will have an answer for the first." As difficult as turbulence is to understand mathematically, we can use art to depict the way it looks. Natalya St. Clair illustrates how Van Gogh captured this deep mystery of movement, fluid and light in his work.
Astronauts Grow a Water Bubble in Space
AdultsGadgetsPhysicsSpace...During Expedition 40 in the summer of 2014, NASA astronauts Steve Swanson and Reid Wiseman - along with European Space Agency astronaut Alexander Gerst - explored the phenomenon of water surface tension in microgravity on the International Space Station. The crew "submerged" a sealed GoPro camera into a floating ball of water the size of a softball and recorded the activity with a 3-D camera.
Brian Cox visits the world's biggest vacuum chamber
AdultsPhysicsScienceExperimentsWatch a bowling ball and a feather fall in the giant vacuum chamber. A simple experiment but it's really amazing.

Why is ketchup so hard to pour?
AdultsFoodPhysicsScienceEver go to pour ketchup on your fries...and nothing comes out? Or the opposite happens, and your plate is suddenly swimming in a sea of red? George Zaidan describes the physics behind this frustrating phenomenon, explaining how ketchup and other non-Newtonian fluids can suddenly transition from solid to liquid and back again.
Anti-Gravity Wheel Explained
AdultsPhysicsScienceEngineering...It's a little shaky but if you average out the oscillations I think the result is clear. Again, huge thank you's to A/Prof Emeritus Rod Cross, Helen Georgiou, Alex Yeung, and Chris Stewart, the University of Sydney Mechanical Engineering shop, Duncan and co. Ralph and the School of Physics.
Anti-Gravity Wheel?
AdultsInternet CulturePhysicsExperiments...In this video I attempt to lift a 19kg (42 lbs) wheel over my head one-handed while it's spinning at a few thousand RPM. This replicates an earlier experiment by Professor Eric Laithwaite. He claimed the wheel was 'light as a feather' and could not be explained by Newton's Laws. I wanted to find out for myself what I really felt like.
When Water Flows Uphill
AdultsPhysicsScienceCooking...In the Leidenfrost Effect, a water droplet will float on a layer of its own vapor if heated to certain temperature. This common cooking phenomenon takes center stage in a series of playful experiments by physicists at the University of Bath, who discovered new and fun means to manipulate the movement of water.
