One thing that being a scientist has taught me is that you can never be certain about anything. You never know the truth. You can only approach it and hope to get a bit nearer to it each time. You iterate towards the truth. You don't know it.

I have heard that the Saudi Arabians are paying Greenpeace to campaign against Nuclear Power. It wouldn't surprise me at all.

If it hadn't been for the Cold War, neither Russia nor America would have been sending people into space.

I suspect any worries about genetic engineering may be unnecessary. Genetic mutations have always happened naturally, anyway.

Life does more than adapt to the Earth. It changes the Earth to its own purposes.

Imagine a survivor of a failed civilization with only a tattered book on aromatherapy for guidance in arresting a cholera epidemic. Yet, such a book would more likely be found amid the debris than a comprehensible medical text.

I would only have been too pleased if someone had asked me for my data. If you really believed in your data, you wouldn't mind someone looking at it. You should be able to respond that if you don't believe me go out and do the measurements yourself.
