When scientists first split the atom, they didn’t realize what they’d done until physicist Lise Meitner figured out they had discovered what we now call nuclear fission.

Hank addresses a highly requested topic - liquid fluoride thorium reactors - and tells us how LFTR might be the future of energy in ... China?

Kirk Sorensen shows us the liquid fuel thorium reactor -- a way to produce energy that is safer, cleaner and more efficient than current nuclear power.

Nathan Myhrvold talks about a few of his latest fascinations -- animal photography, archeology, BBQ and generally being an eccentric genius multimillionaire. Listen for wild stories from the (somewhat raunchy) edge of the animal world.

Hidden beneath Greenland’s ice and powered by a nuclear reactor, Camp Century made for an interesting US military base. But life under the ice came with unique struggles; and although it wasn’t mainly constructed for science, the base...

At Serious Play 2008, Charles Elachi shares stories from NASA's legendary Jet Propulsion Lab -- including tales and video from the Mars Rover project.

In something like water, particles like electrons can beat light in a race - and cause a blue glow to prove it.

If you don't have any idea what antimatter is, you don't have to feel bad - the brightest minds in the world have only recently begun to understand what it is and how it works. Hank gives us the run down on what we know about antimatter,...

Today on SciShow, Hank brings us a little science history, telling us the tale of the world's first human-made nuclear reactor, which was built by a team of scientists and students led by Enrico Fermi in a converted squash court under a...

Our ability to mine great amounts of energy from uranium nuclei has led some to bill nuclear power as a plentiful, utopian source of electricity. But rather than dominate the global electricity market, nuclear power has declined from a...

Nuclear power may not be as bad as you think. If we used Thorium instead of Uranium, we could greatly decrease dangerous radioactive by-products. There is enough Thorium in the world to meet all our energy needs...

Welcome back to the Fluctus Channel for a feature about how challenging life inside a submarine could be. Submariners go beyond every other sailor in terms of accepting new challenges and adapting to new lifestyles. Fluctus is a website...

Explore how nuclear power stations work and what happens when radioactive waste is not contained safely.

The Chernobyl disaster was the worst nuclear accident in history, caused by a series of critical mistakes during a safety test. This video explains the relevant nuclear physics, models the Chernobyl reactor, and demonstrates how...

This video covers: - How the process of nuclear fission works - What a 'chain reaction' is - The pros and cons of nuclear fission General info: - Suitable for all GCSE and IGCSE courses - See below for whether it is higher or foundation...

This program explores the geography, history, and some important cultural features of the Mountain Region of the United States. The individual states of Colorado, Utah, Wyoming, Idaho and Montana are presented in detail.

"How does a nuclear reactor provide energy? What causes a nuclear meltdown? And how do we make this safe?

Patrick Chai, aerospace engineer at NASA’s Langley Research Center in Virginia, covers the challenges and needs for getting humans to Mars and the options for propulsion, duration, time, staging, and more that will be considered on this...

This program explores the geography, history, and some important cultural features of the Mountain Region of the United States. The individual states of Colorado, Utah, Wyoming, Idaho and Montana are presented in detail.

This video is a lecture on nuclear fission and how nuclear power stations utilize it to produce energy. The video explains the concept of fission, the materials used for fission, and how the reaction occurs. The video also covers the...

This video was so dang fun to research, which, of course, I feel super guilty about because, like, real people died. But, after watching the HBO miniseries, I knew there was more to the science of this. I've also heard a lot of stuff...

The story of Three Mile Island shows that nuclear incidents can be prevented, as long as the right safety measures are in place and the employees are trained properly. What happened on Three Mile Island was small in comparison to the...

Nuclear Fission In a nuclear reactor the controlled slow release of energy is used to heat up a closed loop of coolant which passes to heat exchangers which then boil water to provide steam to turn electrical generators. The output of...
