By the end of this talk, there will be 864 more hours of video on YouTube and 2.5 million more photos on Facebook and Instagram. So how do we sort through the deluge? At the TEDSalon in London, Markham Nolan shares the investigative...

A quick explanation of e^(pi i) in terms of motion and differential equations

Sheikha Al Mayassa, a patron of artists, storytellers and filmmakers in Qatar, talks about how art and culture create a country's identity -- and allow every country to share its unique identity with the wider world. As she says: "We...

One afternoon, Kees Moeliker got a research opportunity few ornithologists would wish for: A flying duck slammed into his glass office building, died, and then ... what happened next would change his life. [Note: Contains graphic images...

The Heisenberg Uncertainty Principle might not mean what you think it means: Hank clears things up for us in this edition of IDTIMWYTIM, by distinguishing between the Uncertainty Principle and the Observer Effect, which are often conflated.

In this video Paul Andersen explains how linear motion of an object can be measured using the center of mass. Internal forces within the object can be ignored since they exist in action reaction pairs. A simple way to determine the...

Neil Armstrong, the first man to walk on a world that was not Earth, has died. Getting his pilot's license before his driver's license probably didn't hurt when it came to becoming one of the world's most famous men - certainly the...

For decades the space shuttle was integral to space exploration. In orbit it helped build the ISS, but on the ground it needed help from other gigantic machines.

Science isn't always a visual medium, but I think it's most important moments have often been captured in photos and illustrations. I picked out some of my favorite science images from history.

This video is a footnote for the video about the ring around the earth

Essentially, a ring around the earth is in unstable...

We've broken down our preconceived notions about mass and time, now let's redefine what they really are. Since we know that time is not a universal constant, what is? Matt defines causal order and explains how even though time may look...

In a short, funny, data-packed talk at TED U, Catherine Mohr walks through all the geeky decisions she made when building a green new house -- looking at real energy numbers, not hype. What choices matter most? Not the ones you think.

Design legend Niels Diffrient talks about his life in industrial design (and the reason he became a designer instead of a jet pilot). He details his quest to completely rethink the office chair starting from one fundamental data set: the...

Engineering student Péter Fankhauser demonstrates Rezero, a robot that balances on a ball. Designed and built by students, Rezero is the first ballbot made to move quickly and gracefully -- and even dance. (Could the Star Wars sphere...

In this video Paul Andersen explains how the angular momentum of an object if a product of the rotational inertia and the angular velocity. The rotational inertia depends on the mass, radius and shape of the rotating objects. A sample...

One of the internet's favorite pastimes is arguing, but very few of those arguments ever actually go anywhere. It can be frustrating to watch, but scientists have some ideas on why things play out the way they do.

In 1972, Thomas Sankara was swept into the revolution seeking to wrest control of Madagascar from France’s lingering colonial rule. The protests inspired the West African native to read works by socialist leaders and seek wisdom from...

You may have seen rock sculptures seemingly defying physics in your newsfeed, but what's actually happening?

In this video Paul Andersen explains how the total energy of a system is the combination of kinetic, potential and internal energy of the objects. He then shows you how to calculate the kinetic energy, gravitational potential energy,...

After a long day working on the particle accelerator, you and your friends head to the arcade to unwind. The lights go out for a second, and when they come back, there before you gleams a foosball table. Always game, you insert your...

CALCULUS! Today we take our first steps into the language of Physics; mathematics. Every branch of science has its own way to describe the things that it investigates. And, with Physics, that's math. In this episode, Shini talks us...

In the 17th century, as the British colonies in the Americas were getting established in places like Jamestown, VA, the system of chattel slavery was also developing. Today, we'll learn about the role that slavery played in early...

The famous British historian Lord Acton once said, “Power tends to corrupt, and absolute power corrupts absolutely.” And science tends to agree, but how we can prevent power from going to our heads?

Shameem Akhtar posed as a boy during her early childhood in Pakistan so she could enjoy the privileges Pakistani girls are rarely afforded: to play outside and attend school. In an eye-opening, personal talk, Akhtar recounts how the...
