Quotes on Science

Chance alone is at the source of every innovaton, of all creation in the biosphere. Pure chance, only chance, absolute but blind liberty is at the root of the prodigious edifice that is evolution... It today is the sole conceivable hypothesis, the only one that squares with observed and tested fact. Stating life began by the chance collision of particles of nucleic acid in the "prebiotic soup."

He who lives as children live - who does not struggle for his bread and does not believe that his actions possess any ultimate significance - remains childlike.

Genius is not inspired. Inspiration is perspiration.

If atoms do, by chance, happen to combine themselves into so many shapes, why have they never combined together to form a house or a slipper?

I read a great deal of science fiction with consummate pleasure between, say, the ages of 12 and 16. Then I got away from it. In my mid- to late 20s, I started trying to write it.

[About the great synthesis of atomic physics in the 1920s:] It was a heroic time. It was not the doing of any one man; it involved the collaboration of scores of scientists from many different lands. But from the first to last the deeply creative, subtle and critical spirit of Niels Bohr guided, restrained, deepened and finally transmuted the enterprise.

A day will come when other Israelis will be launched into space in the service of science and progress. For them and for us, Ilan Ramon will always be a source of inspiration as Israel's space pioneer, and his memory will be engraved in our hearts forever.

The only solid piece of scientific truth about which I feel totally confident is that we are profoundly ignorant about nature... It is this sudden confrontation with the depth and scope of ignorance that represents the most significant contribution of twentieth-century science to the human intellect.

[Mathematics] is security. Certainty. Truth. Beauty. Insight. Structure. Architecture. I see mathematics, the part of human knowledge that I call mathematics, as one thing - one great, glorious thing. Whether it is differential topology, or functional analysis, or homological algebra, it is all one thing. ... They are intimately interconnected, they are all facets of the same thing. That interconnection, that architecture, is secure truth and is beauty. That's what mathematics is to me.

We knew the world would not be the same. A few people laughed, a few people cried, most people were silent.

That is the essence of science: ask an impertinent question, and you are on the way to a pertinent answer.

The truth knocks on the door and you say, go away, I'm looking for the truth, and it goes away. Puzzling.
