The Definitive Answer: Does Coriolis Effect cause toilets to drain in opposite directions in the North and South Hemispheres?

Dr. Derek Muller from Veritasium and Destin Sandlin from Smarter Every Day have executed a well planned scientific demonstration to finally clear up the truth about toilet swirl.

Gorilla Reunion

In the African jungle, conservationist Damian Aspinall searches for Kwibi, a lowland gorilla he hasn’t seen for 5 years. Kwibi grew up with Damian at his Howletts Wild Animal Park in England. When he was five, he was released into the forests of Gabon, West Africa as part of conservation programme to re-introduce gorillas back into the wild. Now Kwibi’s 10 years old, much bigger and stronger. Will Damian find him? Will Kwibi attack him?

How to Extract Your Own DNA!

Ever wish you could see the strands of genetic material that make you…you? You can, and there’s no fancy lab equipment required. In this NOVA video short, learn how to extract your own DNA using just a few common household items.

Beautiful Equations

Can equations actually be beautiful? Some of our most famous Scientific Equations are explored. What do they mean? How do scientists derive them?

What is up with Noises?

All about Sound by Vi Heart. This whole video was made by Vi and her family. You gotta love how she leads you through what sounds are, how we hear them, and what it means musically. Also her shear simplistic video style.

Touchable Holography

How can we combine our sense of touch and our sense of site together to create a virtual 3D world where objects that you see can also be felt?

Theo Jansen Creates new Creatures

From the TED site:

Artist Theo Jansen demonstrates the amazingly lifelike kinetic sculptures he builds from plastic tubes and lemonade bottles. His creatures are designed to move — and even survive — on their own.
Dutch artist Theo Jansen has been working for 16 years to create sculptures that move on their own in eerily lifelike ways. Each generation of his Strandbeests” is subject to the forces of evolution, with successful forms moving forward into new designs. Jansen’s vision and long-term commitment to his wooden menagerie is as fascinating to observe as the beasts themselves. His newest creatures walk without assistance on the beaches of Holland, powered by wind, captured by gossamer wings that flap and pump air into old lemonade bottles that in turn power the creatures’ many plastic spindly legs. The walking sculptures look alive as they move, each leg articulating in such a way that the body is steady and level. They even incorporate primitive logic gates that are used to reverse the machine’s direction if it senses dangerous water or loose sand where it might get stuck.

Quantum Levitation

A thin superconductor layer (~1µm thick) is coated on a sapphire wafer. Quantum physics tells us that the magnetic field penetrates into the superconductor in the form of discrete flux tubes. The superconductor strongly pins these tubes, causing it to float in midair.

Moving Atoms – Making the World’s Smallest Movie

How did IBM researchers move all those atoms to make the world’s smallest movie? This short behind-the-scenes documentary takes you inside the lab. Meet the scientists, see how they made a movie with atoms, and find out more about their research in the field of atomic memory and data storage.

Amazing bead chain experiment in slow motion

These beads seem to levitate, defy gravity and jump out of the beaker. But how and why do they act like this? We met up with Steve Mould, the science guy from Britain’s Brightest, to explore the science behind the “self siphoning beads” – also known as “Newton’s Beads”.

To get a closer look at the phenomenon, it is filmed in slow motion to try to work out what exactly was happening, and how the behaviour changes with height.

Flipping of the Sun’s Magnetic Field

Something big is happening on the sun. The sun’s global magnetic field is about to flip, a sign that Solar Max has arrived.

Amazing Resonance Experiment

This experiment is the Chladni plate experiment. A tone generator is used, a wave driver (speaker) and a metal plate attached to the speaker. First,  sand is added to the plate, then a tone is played. Certain frequencies vibrate the metal plate in such a way that it creates areas where there is no vibration. The sand “falls” into those areas, creating beautiful geometric patterns. As the frequency increases in pitch the patterns become more complex.

Untamed Americas – Gigantic School of Rays

A record-breaking school of mobular rays has arrived off the coast of Baja. Filmed in slow motion, they appear to fly in the air!

Athletic Quadcopters

In a robot lab at TEDGlobal, Raffaello D’Andrea demos his flying quadcopters: robots that think like athletes, solving physical problems with algorithms that help them learn. In a series of nifty demos, D’Andrea show drones that play catch, balance and make decisions together. Published on Jun 11, 2013

Gravity:

Three stories that upend our pre-conceived notions about falling:

  1. Falling Cats: David Quammen ponders the terminal velocity of a plummeting cat, teaches Jad a new word, and helps clear up some fallacies of feline physics.
  2. Constantly Falling: Brian Greene explains why he can’t answer the most basic question you can ask a physicist: “why do we fall?”
  3. Falling Fortunes: Garrett Soden and Joan Murray introduce us to the 20th Century’s greatest “gravity hero”–who, despite being the first person to survive a trip over Niagara Falls in a barrel, ultimately landed in a poorhouse.

Time podcast by NPR’s Radiolab

Jorge Luis Borges wrote, “Time is the substance from which I am made. Time is a river which carries me along, but I am the river; it is a tiger that devours me, but I am the tiger; it is a fire that consumes me, but I am the fire.” And it’s still as close a definition as we have. This hour of Radiolab, we try our hand at unlocking the mysteries of time. We stretch and bend it, wrestle with its subjective nature, and wrap our minds around strategies to standardize it…stopping along the way at a 19th-century railroad station in Ohio, a track meet, and a Beethoven concert.
Guests:
Brian Greene, Jay Griffiths, Ben Rubin, Dr. Oliver Sacks and Rebecca Solnit
