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

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.

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.

Life would be tragic if it weren’t funny.

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

To discover the truth in anything that is alien, first dispense with the indispensable in your own vision.

A man sooner or later discovers that he is the master gardener of his soul, the director of his life.

Such is the conscious master, and man can only thus become by discovering within himself the laws of thought; which discovery is totally a matter of application, self-analysis, and experience.

Roots exposed completely vulnerable, stand in bareness see what’s discoverable.

The parts she had buried away were never lost just patiently waiting to be unearthed.

The greatest astonishment of my life was the discovery that the man who does the work is not the man who gets rich.

Modern man is not the man who goes off to discover himself, his secrets, and his hidden truth; he is a man who tries to invest himself.

The ‘Enlightenment, which discovered the liberties, also invented the disciplines.
