“I don’t know what’s the matter with people: they don’t learn by understanding, they learn by some other way — by rote or something. Their knowledge is so fragile.”

I a universe of atoms, an atom in the universe.

Nature has a great simplicity and therefore a great beauty

I don’t feel frightened by not knowing things, by being lost in a mysterious universe without any purpose, which is the way it really is, as far as I can tell. Possibly. It doesn’t frighten me.

You see, I get so much fun out of thinking that I don’t want to destroy this pleasant machine that makes life such a big kick.

To every man is given the key to the gates of heaven. The same key opens the gates of hell.

Philosophers say a great deal about what is absolutely necessary for science, and it is always, so far as one can see, rather naive, and probably wrong.

Nature uses only the longest threads to weave her patterns, so each small piece of her fabric reveals the organization of the entire tapestry.

Why nature is mathematical is, again, a mystery.

I think nature’s imagination Is so much greater than man’s, she’s never going to let us relax

I don’t know what’s the matter with people: they don’t learn by understanding; they learn by some other way—by rote, or something. Their knowledge is so fragile!

We are lucky to live in an age in which we are still making discoveries.

Everything is interesting if you go into it deeply enough

Physicists like to think that all you have to do is say, these are the conditions, now what happens next?

I love to think. I once considered taking drugs as an attempt to better understand an altered state of mind; however, I decided not to. I didn’t want to chance ruining the machine.

Religion is a culture of faith; science is a culture of doubt.

I learned very early the difference between knowing the name of something and knowing something.

An honest man, armed with all the knowledge available to us now, could only state that in some sense, the origin of life appears at the moment to be almost a miracle, so many are the conditions which would have had to have been satisfied to get it going.

Quietly they moved down the calm and sacred river that had come down to earth so that its waters might flow over the ashes of those long dead, and that would continue to flow long after the human race had, through hatred and knowledge, burned itself out.

It is not good to try to stop knowledge from going forward. Ignorance is never better than knowledge.

At each increase of knowledge, as well as on the contrivance of every new tool, human labour becomes abridged.

An honest man here lies at rest, the friend of man the friend of truth the friend of age and guide of youth. Few hearts like his with virtue warmed, few heads with knowledge so informed. If there’s another world, he lives in bliss. If there is none, he made the best of this.

The greatest gain from space travel consists in the extension of our knowledge. In a hundred years this newly won knowledge will pay huge and unexpected dividends.

Humble because of knowledge; mighty by sacrifice.

You gotta know what you are, who you are and how you want to be portrayed.
