I still can't figure out what inspired me to do physics. But since I was nine or ten years old, I wanted to be like [Albert] Einstein. He was my hero. I knew no physicists. I knew no scientists. I had nobody around me. And I went to a convent that didn't even have higher mathematics and physics. I taught myself these subjects in order to get into university.

I do not allow myself to be overcome by hopelessness, no matter how tough the situation. I believe that if you just do your little bit without thinking of the bigness of what you stand against, if you turn to the enlargement of your own capacities, just that itself creates new potential.

In nature's economy the currency is not money, it is life.

When the wilderness movement emerged, it emerged separate from the issue of social inequality and the economic problems of survival. It was a preservationist ecology movement created by an occupying culture. Clearly, a wilderness movement started by Native Americans would not have had the same roots.

I started out in nuclear physics. But after I became more sensitized to the environmental and health implications of the nuclear system - I was being trained to be the first women in the fast-breeder reactor in India (and was in it when it first went critical) - I didn't feel comfortable with it. So I went into theoretical physics.

For us, not cooperating in the monopoly regimes of intellectual property rights and patents and biodiversity - saying "no" to patents on life, and developing intellectual ideas of resistance - is very much a continuation of Gandhian satyagraha. It is, for me, keeping life free in its diversity.
