Steven Weinberg
American Scientist
Certainly science, because of its ability to increase our capacities to do things, raises terrible risks for us all. If it were possible to undiscover nuclear fission, I would be very happy to undiscover it, because of the risks that it puts us all under.
Quote examples
Wilson Greatbatch
Inventor
Rocket scientists agree that we have about reached the limit of our ability to travel in space using chemical rockets. To achieve anything near the speed of light we will need a new energy source and a new propellant. Nuclear fission is not an option.
Quote examples
James Buchan
British Novelist
Of all the failed technologies that litter the onward march of science - steam carriages, zeppelins, armoured trains - none has been so catastrophic to prosperity as the last century's attempt to generate electricity from nuclear fission.
Quote examples
Wilson Greatbatch
Inventor
Nearly all of our existing power sources are generators which use a heat cycle. This includes our coal, oil, and gas fired utilities, our automobiles, trucks, and trains, and even our nuclear fission utility power plants.
Quote examples
Enrico Fermi
Italian Physicist
The fundamental point in fabricating a chain reacting machine is of course to see to it that each fission produces a certain number of neutrons and some of these neutrons will again produce fission.

Inventor
France generates a significant part of its energy requirements from fission reactors and these have achieved a perfect safety record. We build ours all differently.

Robert Zubrin
American Scientist
Before agriculture was invented, land was not a resource. Before oil drilling and nuclear fission were invented, petroleum and uranium were not resources.

The Highway Code can't be that difficult to understand, and yet my brain seems to treat it as a set of nuclear fission instructions in Old Japanese.
