TED-Ed: Could we build a miniature sun on Earth? | George Zaidan
Stars have cores hot and dense enough to force atomic nuclei together, forming larger, heavier nuclei in a process known as fusion. In this process, the mass of the end products is slightly less than the mass of the initial atoms. But...

Why Does Everything Decay Into Lead
If you look at a copy of the periodic table, you might notice that basically every element after lead is labelled as radioactive. And the vast majority of those elements wind up decaying into some version of lead eventually. But why is...

Why Don't We Have Nuclear Fusion Power Yet?
Thanks to LastPass for sponsoring this video. Check out LastPass here: http://bit.ly/2GbcEci Fusion power is supposed to save us from fossil fuels, so when is nuclear fusion going to be a viable option and why has it been so elusive?

What Really Happened the First Time We Split a Heavy Atom in Half
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.

Doomsday Machines
Nuclear weapons represent the darker side of E=mc^2. Science has given us the ability to understand what will happen if these weapons are ever used again.... and what will happen if they are *never* used again.

Conservation of Nucleon Number
In this video Paul Andersen explains how the nucleon number and charge is conserved in all nuclear reactions and radioactive decay. Fission, fusion, alpha decay, beta decay, and gamma decay all conserve the number of neutrons and...

Energy-Mass Equivalence
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...

Nuclear Reactions
Mr. Andersen contrasts nuclear reactions to chemical reactions. He explains the four main forces of nature; including gravity, electromagnetism, strong, and weak nuclear forces. He also explains how fusion differs from fission.

TED-Ed: How do nuclear power plants work? - M. V. Ramana and Sajan Saini
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...

PS1C - Nuclear Processes
Paul Andersen explains three major nuclear processes; fusion, fission, and decay. He begins with a brief discussion of the four fundamental forces in nature. He the explains how nuclei can be combined in fusion, divided through...
