The vacuum of space is a chaotic sea of quantum fluctuations. Some have said that this vacuum energy can be harvested to build our future starship engines, or manipulated to build warp drives. It can't. But it is technically possible to...

Hey remember that time you waved at a stranger who was actually waving at someone behind you? The universe can, at least in its own way. If you thought gravitational waves were wild, just wait until you hear about this thing called...

Transporters and Quantum Teleportation

The weird rules of quantum mechanics lead to all sorts of bizarre phenomena on tiny scales— particles teleporting through walls or being in multiple places at once or simultaneously existing and not. Shame all this magical behavior...

Sometimes our mathematical hacks point to strange new aspects of reality. For example Max Planck used a quantization trick to figure out the spectrum of light emitted by hot objects. The quantization part of his math trick was meant to...

When we finally have a quantum internet you’ll be able to simultaneously like and dislike this video. But we don’t. So I hope you like it. The world is widely regarded as being well and truly into the digital age, also called the...

Today I’m going to explain why you’re not falling through your chair right now using one simple fact, and one object. The fact is that all electrons are the same as each other, and the object is a structurally critical item of my...

If you have perfect knowledge of every single particle in the universe, can you use the laws of physics to rewind all the way back to the Big Bang? Is the entire history of the universe perfectly knowable? Or has information somehow lost...

Paul Dirac's insights into the nature of Quantum Mechanics laid the foundation for Quantum Field Theory and predicted the existence of anti-matter. Part 1 in our series on Quantum Field Theory.

It turns out that "nothing" is one of the most interesting somethings in all of physics.

What is the math behind quantum computers? And why are quantum computers so amazing? Find out on this episode of Infinite Series.

Hank brings us the news about the new Nobel Prize winners in the sciences, what they won for and what it all means.

Let me tell you a story about virtual particles. It may or may not be true.

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....

Transporters and Quantum Teleportation

Can we ever achieve absolute cold?

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.

When the Cold Atom Laboratory launches to the International Space Station in 2016, it will become the coldest spot in the universe. Learn how scientists are going to get closer than ever to absolute zero -- and why they want to.

SUMMARY

The universe is full of opposing forces balanced in a celestial tug-of-war, until they sometimes aren’t. In stars, the two opposing forces are gravity which tries to collapse the star inward, and...

SUMMARY

In 1976, Stephen Hawing proposed that Black Holes, do something impossible according to the laws of quantum mechanics. They destroy information. This is a paradox because information should be conserved in the...

The release of electromagnetic radiation, often in the form of light, from an atom or molecule.

How random are things, really? Well, at the tiny level of photons, randomness might be key to their existence. Einstein could not accept this and famously held the paraphrased opinion that, ‘God does not play dice with the universe’. In...

In this representation I discuss the main principles of quantum mechanics behind the quantum computer. and How to build a device that can manipulate the energy operator of the Schrodinger Equation for an electron to change its spin...

In this part we build three quantum computers that can process simple commands by manipulating the Energy Operators in Schrodinger Equation. <br/>
