When you think about Einstein and physics, E=mc^2 is probably the first thing that comes to mind. But one of his greatest contributions to the field actually came in the form of an odd philosophical footnote in a 1935 paper he co-wrote...

Today on SciShow News: We've learned more about the Zika virus, and we'll tell you how gamers are helping to develop quantum computers.

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!

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.

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...

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...

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...

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...

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...

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...

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...

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...

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.

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...

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....

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...

Hank continues his primer on the strongest of the four fundamental interactions of physics, the strong interaction. Today he talks about the nuclear force and a force carrier called a pion.

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...

Physics investigates why the universe behaves the way that it does, and today, Hank tells us about the three physics experiments that he thinks were the most awesome at helping us understand how the universe works.

The quantum physics of large things: Macro quantum effect. Why don’t tennis balls behave like quantum particles? What happens to a baseball in a double slit experiment? This experiment shows that atoms behave like...

How does a force between particles work? What causes an attraction or repulsion? Why does electromagnetism and gravity have infinite range, but the strong and weak force have a small range? Quantum chromodynamics...

What do we think the universe is quantum? What if the universe was not quantized?

Classical mechanics was doing just fine after Isaac Newton reduced nearly all mechanical phenomena to a single powerful equation:...

Since electromagnetism is so strong, multiple protons in the nucleus of any atom like Helium should repel each other very strongly. So how do they stay glued together?...Because of a force that is even stronger...

“Do photons have mass?” in most textbooks, the answer is no. But is it proven that light does not have any mass? Has anyone every actually confirmed this in a measurement? No.
