Can We Predict Everything
Einstein didn't like quantum mechanics because it wasn't able to make perfect predictions... but science is not about what you like, it's about what's true!

Studying the Brain with... Quantum Mechanics?
Quantum mechanics may not seem like it has anything to do with human psychology, but some psychologists are starting to borrow concepts from the field to help make human behavior more predictable.

How Quantum Mechanics Affects Your Life
While you might not think about quantum mechanics being part of your everyday life, it turns out that it might play a role in some of the most familiar things, from the sunlight in the trees to the nose on your face! Chapters View all...

Wave Function
In this video Paul Andersen explains how the location of matter can be determined at the nanoscale using the wave function. The absolute value of the wave function can be used to determine the probability of finding matter in a location....

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...

TED-Ed: Schrodinger's cat: A thought experiment in quantum mechanics - Chad Orzel
Austrian physicist Erwin Schrodinger, one of the founders of quantum mechanics, posed this famous question: If you put a cat in a sealed box with a device that has a 50% chance of killing the cat in the next hour, what will be the state...

TED-Ed: Hawking's black hole paradox explained | Fabio Pacucci
Today, one of the biggest paradoxes in the universe threatens to unravel modern science: the black hole information paradox. Every object in the universe is composed of particles with unique quantum properties and even if an object is...

Can you win a game of quantum foosball? | Matteo Fadel
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...

Shohini Ghose: Quantum computing explained in 10 minutes
A quantum computer isn't just a more powerful version of the computers we use today; it's something else entirely, based on emerging scientific understanding -- and more than a bit of uncertainty. Enter the quantum wonderland with TED...

The promise of quantum computers | Matt Langione
What if tiny microparticles could help us solve the world's biggest problems in a matter of minutes? That's the promise -- and magic -- of quantum computers, says Matt Langione. Speaking next to an actual IBM quantum computer, he...

Quantum Mechanics - Part 2: Crash Course Physics
e=mc2... it's a big deal, right? But why? And what about this grumpy cat in a box and probability? In this episode of Crash Course Physics, Shini attempts to explain a little more on the topic of Quantum Mechanics.

Who decides how long a second is? | John Kitching
In 1967, researchers gathered to answer a long-running scientific question: just how long is a second? It might seem obvious at first. A second is the tick of a clock, the swing of a pendulum, the time it takes to count to one. But how...

TED-Ed: What is the Heisenberg Uncertainty Principle? - Chad Orzel
The Heisenberg Uncertainty Principle states that you can never simultaneously know the exact position and the exact speed of an object. Why not? Because everything in the universe behaves like both a particle and a wave at the same time....

TED-Ed: How does your smartphone know your location? - Wilton L. Virgo
GPS location apps on a smartphone can be very handy when mapping a travel route or finding nearby events. But how does your smartphone know where you are? Wilton L. Virgo explains how the answer lies 12,000 miles over your head, in an...

Wave Model of an Electron
The wave model of the electron can be used to explain the Bohr model. Electrons are found in certain orbits because they interfere with themselves and create standing waves. When the wavelengths don't match up with a whole integer they...
