TED-Ed: How to detect a supernova - Samantha Kuula
Just now, somewhere in the universe, a star exploded. In fact, a supernova occurs every second or so in the observable universe. Yet, we’ve never actually been able to watch a supernova in its first violent moments. Is early detection...

The First Quantum Field Theory
Quantum mechanics is perhaps the most unintuitive theory ever devised. And yet it's also the most successful, in terms of sheer predictive power. Simply by following the math of quantum mechanics, incredible discoveries have been made....

General Relativity & Curved Spacetime Explained!
We've been through the first few episodes of our crash course on general relativity, and came out alive! But it's officially "time" for CURVED spacetime. Join Gabe on this week's episode of PBS Space Time as he discusses Newton and...

Wave-Particle Duality - Part 1
In this video Paul Andersen explains the wave-particle duality discovered by scientists. In certain situations particles (like electrons and photons) display wave like properties. This phenomenon can best be explored using the double...

Schrödinger's iPad? New Breakthroughs in Quantum Computing
Two developments in quantum computing in the past couple of weeks are the harbingers of a whole new era of smart technology. Google announced that it's building a quantum computer designed by a company called D-Wave in partnership with...

What the World’s Smallest Tweezers Tell Us About DNA
DNA isn’t the simple, loose double-helix you might see in a biology textbook, so isolating single strands of it can be next to impossible. But with some simple tricks of physics, scientists came up with a special type of tweezers that...

Light and Matter
In this video Paul Andersen explains why light is important in probing matter. Light travels in photons and the energy of individual photons is determined by Planck's equation. Infrared spectroscopy is useful in detecting the vibrations...

Stimulated Emission
In this video Paul Andersen explains how stimulated emission can be used to create coherent light. When an atom absorbs a photon it moves to a higher energy level through stimulated absorption. It may then release a photon and moves to a...

How lasers work (in theory)
How does a laser really work? It's Bose - Einstein statistics! (photons are bosons)

Photons
In this video Paul Andersen explains how light travels in photons which can be described as both particles and waves. Einstein showed that photons can be described as particles using the photoelectric effect to show that the energy of a...

Why Am I Upside-Down When I Look in a Spoon?
We'd like to know why you're staring at yourself in a spoon in the first place. But we can at least answer the question of why you look upside-down when you do.

TED-ED: Could we create dark matter? - Rolf Landua
Eighty-five percent of the matter in our universe is dark matter. We don't know what dark matter is made of, and we've yet to directly observe it, but scientists theorize that we may actually be able to create it in the Large Hadron...

TED-Ed: How do animals see in the dark? - Anna Stockl
To human eyes, the world at night is a formless canvas of grey. Many nocturnal animals, on the other hand, experience a rich and varied world, bursting with details, shapes, and colors. What is it, then, that separates moths from men?...

Using Sunlight to Propel Spaceships
When scientists are planning missions, they sometimes have to take into account the fact that the light from the Sun pushes on the spacecraft. But with solar sails, they can also use that pressure to propel the craft along.

Wave-Particle Duality of Light
In this video Paul Andersen explains how light can be treated as both a particle and a wave. Physicists use scale to determine which model to use when studying light. When the wavelength of light is equivalent to the size of the object...
