Chemistry is both creative and incisive, so it gives us both medicines and biological mechanisms.

3. How can chemists best contribute to the world at large?

Help solve the energy problem, probably with practical photovoltaic devices and batteries.

4. Which historical figure would you most like to have dinner with – and why?

Thomas Jefferson, to convince him that Hamilton was right.

6. If exiled on a desert island, what one book and one CD would you take with you?

The recent biography of George Washington, and Bach's Goldberg Variations by Glenn Gould.
