Nuclear Talks...

The following programme is tentative. The talks will be suitable for practically everybody to attend (particularly for those who have felt that science is not for them/ I have never read science/ it is too difficult...). The talks will be presented in a visually attractive manner with no mathematics. The atmosphere is very friendly and relaxed (it is not like school!)

Please encourage your friends and neighbours to come too. The talks are free to attend.

Talk 1: Introduction to the nucleus; we shall address questions about the size, shape, what is the nucleus made of, what holds the nucleus together etc. Rutherford's discovery of the nucleus revolutionised our understanding of the structure of matter.
Talk 2: Radioactivity and its many applications like radio-isotope dating for finding ages of fossils and other objects of historic interest, nuclear medicine etc. will be discussed. Radioactivity is due to the decay of a nucleus into another by emission of energy in the form of alpha, beta and gamma radiation. We shall look at the fascinating history of the discovery of radioactive elements, the reasons why nuclei decay and the nature of the radiation that is emitted.
Talk 3: Nuclear binding energies, Nuclear fission and fusion; explain how energy is released in the fission of uranium and in fusion of hydrogen. We shall look at the particularly interesting history of the discovery of nuclear fission and the development of atomic bomb.
Talks 4 and 5: We look at global energy scene - present and future consumption trends and their impact on our climate. UK energy supply and consumption has special challenges and possibilities. We analyse aspects of nuclear power production in detail with a critical look at those of serious public concerns. Future nuclear reactor designs.
