The feeling is constantly growing on me that I had been the first to hear the greeting of one planet to another.

There is no memory or retentive faculty based on lasting impression. What we designate as memory is but increased responsiveness to repeated stimuli.

Modern science says: 'The sun is the past, the earth is the present, the moon is the future.' From an incandescent mass we have originated, and into a frozen mass we shall turn. Merciless is the law of nature, and rapidly and irresistibly we are drawn to our doom.

Let the future tell the truth, and evaluate each one according to his work and accomplishments. The present is theirs; the future, for which I have really worked, is mine.

My mother says that my father truly enjoyed having a son. My two-years-younger twin sisters felt that he didn't quite know how to enjoy them. But I wasn't aware of those things then. So many of my childhood memories involve him. All the excursions into science were shaped by his knowledge and enthusiasm.

When I started my Ph.D. at the University of California, San Diego, I was told that it would be difficult to make a new discovery in biology because it was all known. It all seems so absurd now.

I had always shown childhood as something difficult, something you want to get the hell out of, but now I wanted to do a story that was the opposite, about that moment in time when you're in that world of discovery, doing what you want to do. That fleeting moment when you're in your zone.

Cadila, India's sixth-largest drugmaker by sales, spent $250 million developing Lipaglyn, a new chemical entity or new discovery, and aims to spend another $150 million to $200 million to launch the drug outside India.
