TED-ED: Electric vocabulary - James Sheils
We all know the words around electricity -- _charge," _positive," _battery" and more. But where do they come from and what do they really mean? Let the history of these words illuminate the physics of electric phenomena.

The Black Hole Tipping Point
This video is about the Schwarzschild radius of a black hole, (its "event horizon"), and how much mass and density is required to reach the point of no return where an object like a star, neutron star, red giant, etc will collapse into a...

The Phantom Singularity
Isaac Newton's Universal Law of Gravitation tells us that there is a singularity to be found within a black hole, but scientists and mathematicians have found a number of issues with Newton's equations. They don't always accurately...

The Unruh Effect
Worried about black holes? Consider this: Every time you accelerate - you generate an event horizon behind you. The more you accelerate away from it the closer it gets. Don't worry, it can never catch up to you, but the Unruh radiation...

White Dwarfs & Planetary Nebulae
Today Phil follows up last week’s look at the death of low mass stars with what comes next: a white dwarf. White dwarfs are incredibly hot and dense objects roughly the size of Earth. They also can form planetary nebulae: huge,...

Joseph DeSimone: What if 3D printing was 100x faster?
What we think of as 3D printing, says Joseph DeSimone, is really just 2D printing over and over ... slowly. Onstage at TED2015, he unveils a bold new technique -- inspired, yes, by Terminator 2 -- that's 25 to 100 times faster, and...

Plastic Bunny 3D Printed From Its Own DNA
A team is encoding digital data into DNA molecules which are then embedded into larger physical objects, like this plastic bunny! And researchers are working on a new, low maintenance oral contraceptive.

Thinking in Scale Level 3 Scale and Perspective
In this video Paul Andersen shows conceptual thinking in a mini-lesson on scale and perspective. TERMS Phenomena - observable events in the natural world (require explanations) Time - an irreversible series of events Space - the...

Objects
In this video Paul Andersen explains how a system can be viewed as an object and an object can be viewed as a system.

Inertial Mass
In this video Paul Andersen explains how inertial mass is defined and measured. When a force is applied to an object or a system it will accelerate. Using Newton's Second Law of Motion (F=ma) you can calculate the inertial mass.

PS3A - Definitions of Energy
In this video Paul Andersen attempts to explain the age old questions - What is Energy? Even though it comes in many forms one of the defining characteristics of energy is that it is conserved over time. He then explains that all energy...

Object Interactions
In this video Paul Andersen explains how object interactions can add or remove mass or energy from a system.

Paola Antonelli: Design and the Elastic Mind
MOMA design curator Paola Antonelli previews the groundbreaking show Design and the Elastic Mind -- full of products and designs that reflect the way we think now.

The Portal Paradox
This video is about the Portal Paradox - a paradox in the video game Portal (and Portal 2) regarding whether or not a companion cube passing through a moving portal plops out of the other end with no speed (velocity, momentum), or shoots...

The Pioneer Probes Are Way Off-Course
The Pioneer 10 and 11 probes were launched to explore outer space, but in the 80s scientists discovered they were veering off-course, and we had no idea why!

What Do Raindrops Really Look Like?
What do raindrops look like? Exactly how we drew them as kids, right? Wrong! Teardrop-shaped rain is physically impossible. This week I went inside a vertical wind tunnel to bring you the true shape of rain.

Thinking in Scale - Level 1 - Describing Scale
In this video Paul Andersen shows conceptual thinking in a mini-lesson on describing scale. TERMS Scale - the relative size or extent of something Objects - a material thing that can be seen and touched Phenomena - observable events in...

How Two Dead Stars Sparked a New Field of Astronomy
Pulsars are more than just cool blinking lights shining across the universe. The discovery of the first binary pulsar paved the way for gravitational wave astronomy astronomy today.

TED-ED: What in the world is topological quantum matter?
David Thouless, Duncan Haldane, and Michael Kosterlitz won the Nobel Prize in Physics in 2016 for discovering that even microscopic matter at the smallest scale can exhibit macroscopic properties and phases that are topological. But -...

TED: How we're teaching computers to understand pictures | Fei-Fei Li
When a very young child looks at a picture, she can identify simple elements: "cat," "book," "chair." Now, computers are getting smart enough to do that too. What's next? In a thrilling talk, computer vision expert Fei-Fei Li describes...

Garik Israelian: How spectroscopy could reveal alien life
Garik Israelian is a spectroscopist, studying the spectrum emitted by a star to figure out what it's made of and how it might behave. It's a rare and accessible look at this discipline, which may be coming close to finding a planet...

Internal Energy
In this video Paul Andersen explains how the internal energy of a system can change as the internal structure of the system changes. An object model will not be able to account for the restoring forces and so a system model must be used....
