Nuclear fission and nuclear fusion - what exactly happens in these processes?
Many of you will have heard the terms "nuclear fission" and "nuclear fusion" before. Nuclear fission means the splitting of atomic nuclei – this is the process by which energy is generated in nuclear power plants. With fusion, it is exactly the other way round: Here, the atomic nuclei amalgamate. But what exactly happens in these two processes, and why is so much energy released in the course?
