We can't avoid age. However, we can avoid some aging. Continue to do things. Be active. Life is fantastic in the way it adjusts to demands; if you use your muscles and mind, they stay there much longer.

The development of science is basically a social phenomenon, dependent on hard work and mutual support of many scientists and on the societies in which they live.

Science, with its experiments and logic, tries to understand the order or structure of the universe. Religion, with its theological inspiration and reflection, tries to understand the purpose or meaning of the universe. These two are cross-related. Purpose implies structure, and structure ought somehow to be interpretable in terms of purpose.

The late Richard Feynman, a superb physicist, said once as we talked about the laser that the way to tell a great idea is that, when people hear it, they say, 'Gee, I could have thought of that.'

Many have a feeling that somehow intelligence must have been involved in the laws of the universe.

At least this is the way I see it. I am a physicist. I also consider myself a Christian. As I try to understand the nature of our universe in these two modes of thinking, I see many commonalities and crossovers between science and religion. It seems logical that in the long run the two will even converge.
