For me it's been very exciting to contribute to the public's understanding of how rich and wondrous science is.

Understanding requires insight. Insight must be anchored.

When we benefit from CT scanners, M.R.I. devices, pacemakers and arterial stents, we can immediately appreciate how science affects the quality of our lives.

Physicists are more like avant-garde composers, willing to bend traditional rules... Mathematicians are more like classical composers.

I believe the process of going from confusion to understanding is a precious, even emotional, experience that can be the foundation of self-confidence.

For most people, the major hurdle in grasping modern insights into the nature of the universe is that these developments are usually phrased using mathematics.

When general relativity was first put forward in 1915, the math was very unfamiliar to most physicists. Now we teach general relativity to advanced high school students.
