Scientists surely have a special responsibility. It is their ideas that form the basis of new technology. They should not be indifferent to the fruits of their ideas. They should forgo experiments that are risky or unethical.

The 'clean energy' challenge deserves a commitment akin to the Manhattan project or the Apollo moon landing.

Crucial to science education is hands-on involvement: showing, not just telling; real experiments and field trips and not just "virtual reality".

To ensure continuing prosperity in the global economy, nothing is more important than the development and application of knowledge and skills.

All space projects push the frontiers of technology and are drivers of innovation.

Some claim that computers will, by 2050, achieve human capabilities. Of course, in some respects they already have.

Let me say that I don't see any conflict between science and religion. I go to church as many other scientists do. I share with most religious people a sense of mystery and wonder at the universe and I want to participate in religious ritual and practices because they're something that all humans can share.
