Our friends at Numberphile provide a detailed look at how the game Connect Four is won or lost.

The Magnus effect is the commonly observed deviation of the spinning ball from a linear flight path. Watch this video to find out why this occurs and what implications it has.

Rosetta revisits the exciting scientific discoveries she has made during her time at Comet 67P/Churyumov-Gerasimenko, including the successful search to find Philae. Now it's time to start preparing to descend to the comet for the end of her extraordinary mission.

They can flow like a liquid and bounce back like a solid. Masses of fire ants show a duality that intrigues physicists.

On stage at Cannes Lions, game designer and author Jane McGonigal showcased research demonstrating the power that gaming can have in the real world.

You've made it to the final round of a game show, and get to pick between 3 doors, one of which has a car behind it! You make your choice, and then the host decides to show you one of the wrong answers. He then offers you the opportunity to change your choice. Should you do it? Find out just how wrong human intuition can be in this classic Monty Hall Problem.

Fuse School: To better understand the science behind global warming, it is important to first understand how the Earth's atmosphere functions. This informative video shows the role of gravity and how the electromagnetic spectrum is involved.

With help from Fuse School, learn the basics about global warming, particularly how burning fossil fuels adds extra carbon dioxide to the atmosphere, and how this then leads to climate change.

Douglas Adams was a writer and author best known for The Hitchhiker’s Guide to the Galaxy. Sadly, he died of a massive heart attack in 2001 at the young age of 49. Each year, fans of his work celebrate the 25th of May (or “Towel Day”) as a tribute to the author.

In a TEDx Talk, brain researcher Dr. Lara Boyd talks about neuroplasticity, how we learn, and how short-term and long-term memory work.

Lara Boyd talks further about behavior bringing about changes to the brain, and about why it's so hard to recover after a stroke.

Lara Boyd concludes her fascinating talk on the brain, explaining how personalized medicine and biomarkers can apply, not just to recovery from stroke and cancer treatment, but to teaching and learning in everyday life.

In the first of a new TED-Ed series designed to catalyze curiosity, TED Curator Chris Anderson shares his boyhood obsession with quirky questions that seem to have no answers.

Fuse School: Learn the basics about the effects of global warming on the environment. Some of the problems global warming may cause are changing climate, extremes of weather, problems for ecosystems, rising sea levels, and ocean acidification.

Physicists, philosophers, and UFO enthusiasts all have ideas on how many universes there may be or if there is extraterrestrial life. Chris Anderson summarizes the theories and expects that in the coming years physicists will arrive at more answers.
