“Life would be tragic if it weren’t funny.”

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.

Time and space are finite in extent, but they don’t have any boundary or edge. They would be like the surface of the earth, but with two more dimensions.

Every man should marry. After all, happiness is not the only thing in life.

Isn’t it funny how danger makes people passionate?

Love, you mock us for your sport.

Carry on, then, if only for the moment that it takes a tiny galaxy to blink!

The best ideas come as jokes. Make your thinking as funny as possible.

It’s OK to have beliefs, just don’t believe in them.

Playing golf is like going to a strip joint. After 18 holes you are tired and most of your balls are missing.

I get a kick out of people saying I was funny.

I could have sexual chemistry with vinegar.
