Radioactivity. We've seen it in movies, it's responsible for the Ninja Turtles. It's responsible for Godzilla. But what is it? It's time to learn exactly what nuclear reactions are, and what it is that makes atomic bombs so destructive,...

This video explains how atomic bombs and nuclear reactors work with a simulation. It also explains why critical mass is a confusing topic in nuclear physics. It depends on a lot more than just the mass.

The video explains two processes involving atomic nuclei that release large amounts of energy - nuclear fission and nuclear fusion. The video explains how uranium 235 can be made to undergo nuclear fission and also discusses the concept...

A nuclear reaction in which two atomic nuclei fuse to form a larger one.

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....

Understand the basics of nuclear power, including how it is generated through the process of fission in uranium atoms. This video highlights the use of neutrons and control rods to create a chain reaction, which ultimately produces...

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...

How the principles of nuclear physics have been used to unleash massive destruction. How do fission bombs and thermonuclear bombs work, and what are the differences between the two? Physics - Energy And Radioactivity - Learning Points....

This program covers the very important topics known as atomic number, mass number, and isotopes. We begin by discussing the structure of the atom and how the atomic number is used to organize the periodic table. We discuss the mass...

This video is about how efficient various reactions are at converting mass to energy (as we know from the Einstein mass-energy equivalence of E=mc^2). Antimatter is very efficient but it is not...

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...

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....

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

A series of reactions, each the result of a preceding reaction.

Thursday, July 30, 2:00 pm - 3:00 pm ET: NSF-funded Physics Frontiers Centers (PFCs) are pushing the frontiers of science across the disciplines of physics. The Joint Institute for Nuclear Astrophysics Center for Evolution...

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...

Find out what happens when an atom splits and why, depending on how this process is controlled, the consequences can be productive or destructive. Physics - Energy And Radioactivity - Learning Points. Nuclear fission creates energy by...

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...

We aren’t using nuclear fusion to generate power yet because it is incredibly difficult to sustain a fusion reaction. The energy requirements are very high, and it is hard to find materials that can withstand such high temperatures. For...

This video explains the process of nuclear fission and how it powers nuclear reactors to produce electricity. Learn how uranium atoms are split to create heat, which then drives steam turbines to generate energy, all while avoiding...

We aren’t using nuclear fusion to generate power yet because it is incredibly difficult to sustain a fusion reaction. The energy requirements are very high, and it is hard to find materials that can withstand such high temperatures....

The video is a lecture on the topic of nuclear fusion, which involves the combination of two small nuclei to form one larger nucleus. The lecturer compares nuclear fusion with nuclear fission, which is the splitting of a nucleus into two...

Uncover the dramatic conclusion of World War II in the Pacific with the deployment of the atomic bomb, reflecting on the profound implications for humanity and the legacy of nuclear warfare.
