THINK IT OVER: a discussion between Professor Charles Coulson , Alex Nicol , and Rev. David Wood
The speakers discuss whether ministers and clergy are, by their training, too greatly separated from working life.
by C. F. Powell, F.R.S.
In this series of four programmes C. F. Powell , Professor of Physics at Bristol University, talks to a group of laymen about the structure of the atom, the fusion process, the fission process, and the production and use of nuclear energy.
2-The Fusion Process
The most remarkable event in the recent history of mankind is the imitation of the processes whereby the sun releases the energy that has given the world life. This imitation occurs in the fusion process in ZETA. Professor Powell explains how the nuclei of deuterium are made to fuse at temperatures of five million degrees centigrade without vapourising the equipment, why this releases energy, and how deuterium can be readily obtained from the oceans.
There are more than 5 million programme listings in Genome. This is a
historical record of the planned output and the BBC services of any
given time. It should be viewed in this context and with the
understanding that it reflects the attitudes and standards of its time
- not those of today.
Genome is a digitised version of the Radio Times from 1923 to 2009 and
is made available for internal research purposes only. You will need to
obtain the relevant third party permissions for any use, including use in
programmes, online etc.
This internal version of Genome, which includes all the magazine covers,
images and articles as well as the programme listings from the Radio
Times, is different to the version of BBC Genome that is available
externally/to the public. It is only available inside the BBC network.
