Weapons of mass destruction violate more than individual lives - they cross international borders and jeopardize all people. They also drain resources that could be used instead for medicines, schools and other life-saving supplies. We must come together with even greater determination to prevent a WMD nightmare.

Perhaps scientists have been the most international of all professions in their outlook... Every time you scientists make a major invention, we politicians have to invent a new institution to cope with it-and almost invariably, these days, it must be an international institution.

Science seeks the truth. And it does not discriminate. For better or worse it finds things out. Science is humble. It knows what it knows and it knows what it doesn’t know. It bases its conclusions and beliefs on hard evidence -­- evidence that is constantly updated and upgraded. It doesn’t get offended when new facts come along. It embraces the body of knowledge. It doesn’t hold on to medieval practices because they are tradition.

We live in a dancing matrix of viruses; they dart, rather like bees, from organism to organism, from plant to insect to mammal to me and back again, and into the sea, tugging along pieces of this genome, strings of genes from that, transplanting grafts of DNA, passing around heredity as though at a great party.

You can prove anything you want by coldly logical reason---if you pick the proper postulates.

It's a pity that nobody has found an exploding black hole. If they had, I would have won a Nobel prize.
