Episode 6: Heat and the Human Body

Shedding Light on Heat

In the final episode, 'Heat and the Human Body', we look at the brilliant systems within our bodies that allow us to maintain a more-or-less constant body temperature regardless of the weather conditions. Sweating, shivering, pumping more blood...Show More

Nuclear Power: Risks and Benefits

Nuclear Power: Risks and Benefits

Nuclear Energy

Nuclear energy generates massive amounts of electricity but also produces highly dangerous radioactive waste. This clip explains waste production in reactors, its treatment and containment and how technology continues to improve safety around...Show More
Nuclear Fission Reactors

Nuclear Fission Reactors

Nuclear Energy

Nuclear reactors contain radioactive fuel that undergoes fission, producing immense heat that drives turbines. Globally, about 10 per cent of electricity is generated this way. This clip details what happens inside a reactor, nuclear fuel and its...Show More
Nuclear Fission

Nuclear Fission

Nuclear Energy

Understanding how nuclear fission produces such vast quantities of energy starts with unimaginably tiny sub-atomic particles. This clip details how fission occurs in radioactive nuclei to release energy. It also explores why the amount of energy...Show More
Nuclear Fusion

Nuclear Fusion

Nuclear Energy

The energy produced by nuclear fusion powers stars like our own Sun. This clip examines nuclear fusion, including what occurs at the sub-atomic level and why the energy released by fusion is vastly greater than in nuclear fission. Einstein’s...Show More
