“The definition of an optimist. People not with a hopeful view of the future, but rather, people who simply believe that any problem that does not contradict the laws of physics can ultimately be solved.” David Deutsch

“Nobody ever figures out what life is all about, and it doesn’t matter. Explore the world. Nearly everything is really interesting if you go into it deeply enough.” Richard Feynman

“The fact is that no species has ever had such wholesale control over everything on earth, living or dead, as we now have. That lays upon us, whether we like it or not, an awesome responsibility. In our hands now lies not only our own future, but that of all other living creatures with whom we share the earth.” David Attenborough

“Sit down before fact like a little child, and be prepared to give up every preconceived notion, follow humbly wherever and to whatever abyss Nature leads or you shall learn nothing.” Thomas Huxley

“Experiment is the sole source of truth. It alone can teach us something new; it alone can give us certainty.” Henri Poincaré

“The feeling of awed wonder that science can give us is one of the highest experiences of which the human psyche is capable. It is a deep aesthetic passion to rank with the finest that music and poetry can deliver. It is truly one of the things that make life worth living and it does so, if anything, more effectively if it convinces us that the time we have for living is quite finite.” Richard Dawkins

“It doesn’t seem to me that this fantastically marvelous universe, this tremendous range of time and space and different kinds of animals, and all the different planets, and all these atoms with all their motions, and so on, all this complicated thing can merely be a stage so that God can watch human beings struggle for good and evil — which is the view that religion has. The stage is too big for the drama.” Richard Feynman

(…) there is no such thing as independence in nature. The whole of nature is a unified system of interdependent variables, each a cause and a reaction, existing only as a concentrated whole.

“You don’t see the plug to connect to the environment, so it looks like we’re free… wandering around. Take the oxygen away, we all die immediately. Take plant life away, we die. And without the sun, all the plants die. So we are connected.”

(…) when are we really going to start taking that into account? That’s what it is to be successful. Success depends on how well we relate to everything around us. Jacque Fresco

“I’m comfortable with the unknown – that’s the point of science. There are places out there, billions of places out there, that we know nothing about. And the fact that we know nothing about them excites me, and I want to go out and find out about them.

And that’s what science is.

So I think if you’re not comfortable with the unknown, then it’s difficult to be a scientist… I don’t need an answer. I don’t need answers to everything. I want to have answers to find.” Professor Brian Cox

“Reality is not an exhibit for man’s inspection, labeled: "Do not touch.” There are no appearances to be photographed, no experiences to be copied, in which we do not take part.

Science, like art, is not a copy of nature but a re-creation of her. We re-make nature by the act of discovery, in the poem or in the theorem. And the great poem and the deep theorem are new to every reader, and yet are his own experiences, because he himself re-creates them. They are the marks of unity in variety; and in the instant when the minds seizes this for itself, in art or in science, the heart misses a beat.“ Jacob Bronowski

“No amount of experimentation can ever prove me right; a single experiment can prove me wrong.” Albert Einstein
