Scientists have warned that as CO2 levels in the atmosphere rise an increase in Earth’s temperature by even two degrees could lead to catastrophic effects across the world. But how can such a tiny, measurable change in one factor lead to huge, unpredictable changes elsewhere? Victor J. Donnay uses billiards to illustrate tipping points, chaotic motion and their implications on climate change.

Lesson by Victor J. Donnay, animation by Karrot Animation.

Discover what we know — and don’t know — about the causes and treatment of seizures, and what to do if you encounter someone experiencing a seizure.

Uploaded 03-08-21

--

Nearly 3,000 years ago, a Babylonian tablet described a curious illness called “miqtu” that caused symptoms ranging from facial twitching to full body convulsions. Today we know miqtu as seizures, and modern medicine has developed numerous treatments for those experiencing them. So what causes seizures, and is there any way to stop them from happening? Christopher E. Gaw investigates.

Explore the massive structures known as the Fermi bubbles, and dig into the prevailing theories about how they came to be.

--

In 2010, NASA announced the discovery of a never-before-seen galactic object: two gigantic gaseous bubbles, each emanating an impressive 25,000 light years from the center of the Milky Way. Astronomers were perplexed: what created these structures? And could this mean that the black hole at the center of our galaxy was waking up? Ashkbiz Danehkar explores the possible origins of the Fermi bubbles.

Clever lab experiments (and brain scans) show how 6-month-old babies use sophisticated reasoning to understand their world. (Filmed at TEDxRainier.)

Dig into the engineering of rollercoasters, and explore how these thrilling rides are built to be scary and safe at the same time.

Uploaded 29-10-18

--

In 1895, crowds flooded Coney Island to see America’s first-ever looping coaster: the Flip Flap Railway. But its thrilling flip caused cases of severe whiplash, neck injury and even ejections. Today, coasters can pull off far more exciting tricks and do it safely. Brian D. Avery investigates what rollercoasters are doing to your body and how they’ve managed to get scarier and safer at the same time.
