I have a deep connection with Mahatma Gandhi, partly because my mother was a very, very staunch Gandhian and brought us up that way. When I was six years old, and all the girls were getting nylon dresses, I was very keen to get a nylon frock for my birthday. My mother said, “I can get it for you, but would you rather—through how you live and what you wear and what you eat—ensure that food goes into the hands of the weaver or ensure that profits go into the bank of an industrialist?” That became such a checkstone for everything in life.

I have called this phenomenon of stealing common knowledge and indigenous science "biopiracy" and "intellectual piracy." According to patent systems we shouldn't be able to patent what exists as "prior art." But the United States patent system is somewhat perverted. First of all, it does not treat the prior art of other societies as "prior art." Therefore anyone from the United States can travel to another country, find out about the use of a medicinal plant, or find a seed that farmers use, come back here, claim it as an invention or an innovation.

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.

Nobody defines it as something women shouldn't be doing. In a way, there are more mathematicians, more doctors, more scientists in India than there are in this country. We even had a woman head of state, and that's something the United States has yet to catch up with.

The art of teaching is clarity and the art of learning is to listen.

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.

When you don't take into account the way ecological systems work, then you do damage.
