Description
Professor Wysession explains how uranium is used to make electricity through the process of nuclear fission, from acquiring uranium-bearing rocks to disposing of leftover nuclear waste. Afterwards, learn some of the upsides of nuclear energy (including its nearly unlimited power) and its downsides (such as its inability to become decentralized or portable).
Description
In the 1940s, scientists worked out techniques for speeding up the radioactivity of uranium isotopes by means of a fission chain reaction. See this process modeled with an array of mousetraps, demonstrating how the reaction can be controlled in a reactor or unleashed catastrophically in a bomb.

Description
The story of two close friends who discovered nuclear fission is told in great detail within the context of both World Wars. This video is as much about role of scientists in political events, social responsibility, and discrimination against women and Jews, as it is about the science, though the science is clearly explained. Archival film footage and photographs are extensively and effectively used throughout the production. Most fascinating are...

"As a female Jewish physicist in Berlin during the early 20th century, Lise Meitner had to fight for an education, a job, and equal treatment in her field, like having her name listed on her own research papers. Meitner made groundbreaking strides in the study of radiation, but when Hitler came to power in Germany, she suddenly had to face not only sexism, but also life-threatening anti-Semitism as well. Nevertheless, she persevered and one day made...

Probe the tradeoffs of oil, natural gas, and nuclear fission for generating electrical power. For example, natural gas is plentiful and flexible, but it involves fracking and produces carbon dioxide emissions. By contrast, nuclear power produces essentially zero emissions but poses potentially catastrophic safety risks..
Description
Investigate nuclear fission, in which a heavy, unstable nucleus breaks apart; and nuclear fusion, where light nuclei are joined. In both, the released energy is millions of times greater than the energy from chemical reactions and comes from the conversion of nuclear binding energy to kinetic energy.

"A personal trip turns perilous after the murder of a British spy in Washington, D.C., forces Elena Standish to face dark family secrets in this exciting 1930s mystery by bestselling author Anne Perry. On a family trip to Washington, D.C., Elena Standish is delighted to visit her mother's parents for their anniversary and celebrate with influential friends of her grandfather, a prominent scientist. Even Franklin and Eleanor Roosevelt will attend the...
Description
Travel to the subatomic level for a fascinating exploration of how nuclear energy is generated. It’s an eye-opening lecture that touches on everything from nuclear fission and radioactive decay to the inner workings of nuclear power plants and the attendant fears and concerns of core meltdowns.

You cannot hide from radioactivity. Even the book you are holding is slightly radioactive, but there are more serious risks. Radioactivity, the breakdown of unstable atomic nuclei, releasing radiation, is a fundamental process in nature. It is a process that has been harnessed to provide wide and important applications in science, medicine, industry, and energy production. But it remains much misunderstood, and feared, perhaps because nuclear radiation...

Energy is, without a doubt, the very foundation of the universe. It’s the engine that powers life and fuels the evolution of human civilization...Yet for all its importance, what energy really is and how it works remains a mystery to most non-scientists. For example:..• Where does most of our energy come from, and how is it sourced?.• How do energy technologies, both primitive and cutting-edge, generate power?.• How do we store energy—and...
