What does an electron really look like? I mean, if we zoom in all the way. Is it a sizeless speck of charge? Is it a multidimensional vortex of quantum strangeness? Is it the boundary of a tiny universe with universe-electrons of its...

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...

Quantum computers obtain superpowers by tapping into parallel universes, says Hartmut Neven, the founder and lead of Google Quantum AI. He explains how this emerging tech can far surpass traditional computers by relying on quantum...

We can make clocks that keep accurate time for millions of years. We can also make clocks with such high resolution they tick one billion billion times per second. So why can't we make a clock that does both?

Physicists have a long history of sticking our noses where they don’t belong - and one of our favorite places to step beyond our expertise is the question of consciousness and free will. Sometimes our musings are insightful, sometimes...

Objective Collapse Theories offer a explanation of quantum mechanics that is at once brand new and based in classical mechanics. In the world of quantum mechanics, it’s no big deal for particles to be in multiple different states at the...

How many times can I half the distance between my hands? Assume perfect coordination and the ability to localize my palms to the quantum level. 15 halvings gets them to within a cell’s width. 33 to within a single atom, 50 and they’re a...

Entropy is surely one of the most perplexing concepts in physics. It’s variously described as a measure of a system’s disorder - or as the amount of useful work that you can get from it - or as the information hidden by the system....

The device you’re watching this video on is best understood by thinking about positive and negative charges moving around a circuit of diodes and transistors. But the only elementary particle actually flowing in the circuit is the...

Where are you right now? Until you interact with another particle you could be any number of places within a wave of probabilities. This is only one way that quantum mechanics challenges our perception of reality. Matt dives into these...

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...

Planck's Length is the length below which the concept of length loses its meaning. What exactly does that mean and what are the incredible implications this fact has upon our reality? To find out check out this episode of Space Time...

The double slit experiment radically changed the way we understand reality. Find out what the ramifications of this experiment were and how we can use it to better comprehend our universe.

Causality is meant to move in one direction: forward. But the Quantum Eraser experiment seems to reverse causality. How and why can this happen and what are the implications of this experiment on how we understand Quantum Mechanics and...

Kinetic and potential energy are defined as combinations of more basic quantities: position, velocity and mass. These combinations are chosen so that their sum is conserved. It’s actually remarkable that there’s any such combination of...

Atomic clocks are the best timekeepers humanity's got these days, but scientists are working toward something even better: a SUB-atomic (aka nuclear) clock.

One Minute Physics provides an energetic and entertaining view of old and new problems in physics -- all in one minute!

Can you imagine a cup of tea that doesn't obey the laws of physics? One that pours out of the bottom of your cup while crawling up the sides to the top? Join Hank Green for a fun new SciShow super episode all about superfluids!

Scientific discovery often dabbles in the extreme, challenging and exceeding what we think of as "possible." And this year's discoveries were no different! We present to you three scientific discoveries made this year that set out to...

Water is one of the most abundant and important substances on Earth, so you think we'd know everything there is to know about it. Turns out, water is so much stranger and more complex than we ever thought! Join Olivia Gordon for a new...

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!

The general uncertainty principle, about the concentration of a wave vs the concentration of its fourier transform, applied to two non-quantum examples before showing what it means for the Heisenberg uncertainty principle.

Classical computers struggle to crack modern encryption. But quantum computers using Shor's Algorithm make short work of RSA cryptography. Find out how.
