- Merit Review: Investing in People and IdeasWhile I was chair of the National Science Board (NSB), which is the Presidentially appointed body charged with oversight of the U.S. National Science Foundation (NSF), we launched a comprehensive review of how NSF selects and competitively awards funding for research proposals. We did so recognizing that leadership of the United States in Science, Technology,… Read more: Merit Review: Investing in People and Ideas
- A Canticle for ReasonN.B. This is an old article, written a decade ago, but shared only informally with a few. In today’s uncertain world, it seems appropriate to share it more widely.

I would rather have questions that can’t be answered than answers that can’t be questioned. — Richard Feynman

Writing is perhaps the greatest of human inventions, binding together people who never knew each other, citizens of distant epochs. Books break the shackles of time. A book is proof that humans are capable of working magic. — Carl Sagan

I am often asked, ‘What made you become a scientist?’ But I can’t stand far enough away from myself to give a really satisfactory answer, for I cannot distinctly remember a time when I did not think that a scientist was the most exciting possible thing to be.” — Peter Medawar
