Because of security restrictions on the publication of potentially war-relevant research, nuclear fission is simply lacking in the spectrum of themes documented in the map.
Nuclear power, nuclear fusion and nuclear fission are of vital importance.
Nuclear fission, moreover, is viewed as one of the better ways of addressing 'climate change', with saving and efficiency relegated to secondary importance.
We all know that nuclear fission is an inherently dangerous process, as indeed is a fission in our economies.
There were comparable cold spells in 17th and 18th centuries before the discovery of nuclear fission.
That may be regarded, perhaps, as a new example of nuclear fission.
Provision for research and development into nuclear fission in 1989–90 was £135–4 million.
I believe the scientists should not be used by politicians or statesmen, no matter how brilliant they are, in keeping so-called nuclear fission secrets.
