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

This video is about the original cold fusion: μ muon-catalyzed cold fusion of deuterium, tritium, hydrogen, into helium-3 and helium 4. The problems with it are the half-life of muons and the sticking of muons to alpha particles. Also...

Why are Stars Star-Shaped

This video is about using particle accelerators as part of the solar panel silicon wafer manufacturing process. The accelerators embed protons into the wafer crystals, allowing them to break and separate from the main crystal in much...

Last week, the recipients of the 2017 Nobel Prizes were announced. We take a closer look at the winners of the Physiology and Chemistry Awards, whose breakthroughs change the way we study sleep, and allow us to look at microscopic...

Real World Telekinesis (feat. Neil Turok)

This video explains Shor’s Algorithm, a way to efficiently factor large pseudoprime integers into their prime factors using a quantum computer. The quantum computation relies on the number-theoretic analysis of the factoring problem via...

The universe is a pretty grand place to live, but scientists have one issue with it, it's an anomaly that should be scientifically impossible.

So, variables. There are lots of them when trying to test an idea. The trick is to isolate one variable at a time to get reliable results every time. But, how do we do that? In this episode of Crash Course Kids, Sabrina shows us how to...

Our universe started with the Big Bang, but how will it end? Explore cosmologists’ three possible scenarios: the Big Crunch, the Big Freeze and the Big Rip. -- We know about our universe’s past: the Big Bang theory predicts that all...

In this video Paul Andersen explains how a system can be viewed as an object and an object can be viewed as a system.

This video is about the famous 'Twins paradox' of special relativity, how time can appear to be faster for two different observers at the same time, and which twin really is older (or younger) - the one who stays on earth or the one who...

In this episode, I revisit the wave particle duality and present an intuitive analogy for understanding how it works.

This video explains how Shor’s Algorithm factors the pseudoprime number 314191 into its prime factors using a quantum computer. The quantum computation relies on the number-theoretic analysis of the factoring problem via modular...

At the beginning of the 20th century, many scientists thought that we had learned all there was to know about physics. The problem is, the better we get at measuring things and building models of our universe, the more we discover that...

In this video Paul Andersen explains how inertial mass is defined and measured. When a force is applied to an object or a system it will accelerate. Using Newton's Second Law of Motion (F=ma) you can calculate the inertial mass.

How To Detect A Secret Nuclear Test

As the year 1905 began, Albert Einstein faced life as a "failed" academic. Yet within the next twelve months, he would publish four extraordinary papers, each on a different topic, that were destined to radically transform our...

Pulsed plasma thrusters use the same stuff that’s on your frying pan to make spacecraft zoom around the universe. And they’ve been doing it since the 1960s.

The universe that we know, with its luminous stars and orbiting planets, is largely made up of elements we can't actually see -- like dark energy and dark matter -- and therefore don't fully understand. Theoretical physicist Chanda...

Scientists have been searching for alien life by honing in on the existence of liquid water, but we might be overlooking some types of life out there that doesn't need water at all.

Scientists studying Comets 67P and Lovejoy have discovered oxygen, alcohol, and the building block of sugar. Sounds like a regular Friday night on earth, but it’s the first time we’ve found any of these things on a comet.

This video is about how we don't just need energy to power our lives, we need *low entropy* energy! Thanks to Google Making and Science for supporting this series, and to Sean Carroll for collaborating on it! This video is about how we...
