The brightest flashes in the world of thought are incomplete until they have been proven to have their counterparts in the world of fact.
I had set out to disprove quantum field theory - and the opposite occurred! I was shocked.
If I were to awaken after having slept for a thousand years, my first question would be: Has the Riemann hypothesis been proven?
As species are exterminated by shifting climate zones, ecosystems can collapse, destroying more species.
We sat here during Irene in '99 with the back door open. We drank and watched all the stuff fly by.
The Earth isn't an infinite sheet that carries on for ever, but it doesn't have an edge, either. It's compact and connected.
Now, our Sun will not collapse to a black hole. It's actually not massive enough.
I entered the Physics Department in 1950, receiving a Master's degree in 1953 and a Ph.D. in 1956. It is difficult to convey the sense of excitement that pervaded the Department at that time.
I was lucky to grow up at a time when it was not difficult for the child of a tenant farmer to make his way to the state university.
In course of time the Brothers Cowper removed the manufacture of their printing machines from London, to Manchester. There they found skilled and energetic workmen, ready to carry their plans into effect.
Travel at faster than the speed of light certainly can have dramatic implications that are difficult to understand, such as time travel.
A lot of my research time is spent daydreaming - telling an imaginary admiring audience of laymen how to understand some difficult scientific idea.
Seven years is a long time, and he was there for me, when my mum died. He was very compassionate at that time. I couldn't have found anyone better in that situation.
The truth of Moore's law has made remarkable things possible. On the software side, I think natural user interfaces in all their forms are equally significant.
We have found that where science has progressed the farthest, the mind has but regained from nature that which the mind put into nature.
Quantum computation is... a distinctively new way of harnessing nature... It will be the first technology that allows useful tasks to be performed in collaboration between parallel universes.
Fortunately, nature is as generous with its problems as Nobel with his fortune. The more we know, the more aware we are of what we know not.
String theory is an attempt at a deeper description of nature by thinking of an elementary particle not as a little point but as a little loop of vibrating string.
It takes so long to train a physicist to the place where he understands the nature of physical problems that he is already too old to solve them.
The law in question asserts, that the quantity of force which can be brought into action in the whole of Nature is unchangeable, and can neither be increased nor diminished.
Nature gives us all, including Prof. Lorentz, surprises. It was very quickly found that there are many exceptions to the rule of splitting of the lines only into triplets.
