“We waste time, so you don’t have to.”

Time travel may be possible, but it is not practical.

Science is not only a disciple of reason but, also, one of romance and passion.

It matters if you just don’t give up.

We are all now connected by the Internet, like neurons in a giant brain.

One can’t prove that God doesn’t exist. But science makes God unnecessary. The laws of physics can explain the universe without the need for a creator.

I have experimental evidence that time travel is not possible.

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

I believe everyone should have a broad picture of how the universe operates and our place in it. It is a basic human desire. And it also puts our worries in perspective.

I like physics, but I love cartoons.

One is always a long way from solving a problem until one actually has the answer.

If you are lucky enough to find love, remember it is there and don’t throw it away.

When something is made idiot proof, they will just make better idiots.

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

We only have to look at ourselves to see how intelligent life might develop into something we wouldn’t want to meet.

Intelligence is the ability to adapt to change.

What I meant by ‘we would know the mind of God’ is, we would know everything that God would know, if there were a God. Which there isn’t. I’m an atheist.

Those who create are rare; those who cannot are numerous. Therefore, the latter are stronger.

I’ve always said to myself that if a little pocket calculator can do it why shouldn’t I?

We may have all come on different ships, but we’re in the same boat now.

Find out what a person fears most and that is where he will develop next.

Stop acting so small. You are the universe in ecstatic motion.

You were born with wings, why prefer to crawl through life?

If you don’t stand for something you will fall for anything.

Nothing is impossible, the word itself says I’m possible!
