“I’ve noticed that even people who believe in fate look both ways before crossing the street.”

I’d say I don’t believe in God, but I’m afraid He might hear me.

There is a fundamental difference between religion, which is based on authority, and science, which is based on observation and reason. Science will win because it works.

I have experimental evidence that time travel is not possible.

Science can explain the universe without the need for a Creator.

Scientific discovery may not be better than sex, but the satisfaction lasts longer.

Don’t talk too much. Don’t pop off. Don’t talk after the game until you cool off.

Don’t keep forever on the public road, going only where others have gone and following one after the other like a flock of sheep. Leave the beaten track occasionally and dive into the woods.

I believe that India is such a big country that one must do as much work as possible. So I keep doing that.

It’s hard to believe, but anything can happen. Accidents do happen, unfortunately, it happened at the worst time.

Money and fame made me believe I was entitled. I was wrong and foolish.

Behavior is what a man does, not what he thinks, feels, or believes.

If I believe in God and life after death and you do not, and if there is no God, we both lose when we die. However, if there is a God, you still lose and I gain everything.
