This week we are exploring alternative energy sources. We'll look at how biomass can be burned as a fuel source, how hydrogen can be used in a fuel cell to generate electrical power, and how nuclear fission provides power to the grid....

In this video Paul Andersen explains how the law of conservation of energy applies to both energy and mass. Einstein showed that mass and energy are equivalent and that the amount of energy contained within matter can be calculated...

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...

You might be benefiting from the weird units you've never heard every time you put on your shoes or read about dark matter.

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...

Mr. Andersen explains why radiation occurs and describes the major types of radiation. He also shows how alpha, beta, and gamma radiation affect the nucleus of a radioactive atom. Nuclear equations are also discussed.

The perfect balance of radioactive elements inside planets like ours might make it habitable, and researchers are challenging some ideas about how Mars is losing its water.

Continuing our look at Nuclear Chemistry, Hank takes this episode to talk about Fusion and Fission. What they mean, how they work, their positives, negatives, and dangers. Plus, E=mc2, Mass Defect, and Applications of Fission and...

In this episode, Hank welcomes you to the new age, to the new age, welcome to the new age. Here he'll talk about transmutation among elements, isotopes, calculating half-life, radioactive decay, and spontaneous fission....

The Radium Girls were the first people who worked, for years, with one of the world's most radioactive substances -- and suffered the consequences.

Mr. Andersen describes the major groups on the periodic table.

Iran becomes an Islamic Republic as Ayatollah Khomeini seizes power to become Supreme Leader. Part 5 of our journey through history's greatest revolutions--the moments that shaped modern civilization.

China will rapidly expand its nuclear energy production over the next 15 years as part of an all-of-the-above energy push to meet its people's insatiable demand for electricity.

At 5:30AM, dawn on July 16, 1945 near a small town called Alamagordo New Mexico, the course of human history was changed. The first atomic bomb was detonated that day, and sealed the fate of humanity....

A 45,500-year-old warty pig drawing is the oldest known cave painting of an animal on record. The piggies were painted in Indonesian caves.

Analysis of a space rock that landed on a frozen Michigan lake revealed a rich array of extraterrestrial organic compounds. Learn how the meteorite might have been incorporated into life on Earth.

It’s highly unlikely to shoot down a missile mid-air. But there's more to it than that! Causing a nuclear bomb to detonate requires a precise orchestration of events, without which the chain reaction does not initiate and the bomb...

Little Boy And Fat Man are the nicknames given to the two weapons of mass destruction that devastated Hiroshima and Nagasaki, seem ridiculous when thinking about what they were capable of doing. Little Boy was the first nuclear bomb to...

Robert J. Oppenheimer, born on April 22, 1904, is known as the father of the atomic bomb. Oppenheimer was awarded a PhD in theoretical physics and was interested in the emerging field of quantum physics. As a scientist at the University...
