Famous Quotes & Sayings

Richard P. Feynman

I can live with doubt and uncertainty and not knowing. I think it is much more interesting to live not knowing than to have answers that might be wrong. If we will only allow that, as we progress, we remain unsure, we will leave opportunities for alternatives. We will not become enthusiastic for the fact, the knowledge, the absolute truth of the day, but remain always uncertain … In order to make progress, one must leave the door to the unknown ajar.

Richard P. Feynman

Unless a thing can be defined by measurement, it has no place in a theory. And since an accurate value of the momentum of a localized particle cannot be defined by measurement it therefore has no place in the theory.

Richard P. Feynman

It is odd, but on the infrequent occasions when I have been called upon in a formal place to play the bongo drums, the introducer never seems to find it necessary to mention that I also do theoretical physics.

Richard P. Feynman

Science is a way to teach how something gets to be known, what is not known, to what extent things are known (for nothing is known absolutely), how to handle doubt and uncertainty, what the rules of evidence are, how to think about things so that judgments can be made, how to distinguish truth from fraud, and from show.

Richard P. Feynman

Scientists are explorers. Philosophers are tourists.

Richard P. Feynman

If you thought that science was certain - well, that is just an error on your part.

Richard Whately

To teach one who has no curiosity to learn, is to sow a field without ploughing it.

William S. Burroughs

They tend to be suspicious, bristly, paranoid-type people with huge egos they push around like some elephantiasis victim with his distended testicles in a wheelbarrow terrified no doubt that some skulking ingrate of a clone student will sneak into his very brain and steal his genius work.

Woody Allen

Astronomers say the universe is finite, which is a comforting thought for those people who can't remember where they leave things.

Evan Thomas

I think in our lifetime there is a probability that one of these weapons is going to go off in New York or Washington or some big city like that. The CIA needs to be doing everything it possibly can to penetrate terrorist cells and outlaw states.

Thomas R. Insel

Most of our brain cells are glial cells, once thought to be mere support cells, but now understood as having a critical role in brain function. Glial cells in the human brain are markedly different from glial cells in other brains, suggesting that they may be important in the evolution of brain function.

Triple H

Alcohol does kill brain cells, because you've lost it.

Sara Zarr

I tried his cell over and over but he never answered. Then I’d call just to hear his voice on the outgoing message, until eventually that was gone too.

Richard Dawkins

When you plant a fertile meme in my mind you literally parasitize my brain, turning it into a vehicle for the meme's propagation in just the way that a virus may parasitize the genetic mechanism of a host cell.

James Gleick

The cells of an organism are nodes in a richly interwoven communications network, transmitting and receiving, coding and decoding. Evolution itself embodies an ongoing exchange of information between organism and environment.

Lynn Margulis

The idea that we are "stewards of the earth" is another symptom of human arrogance. Imagine yourself with the task of overseeing your body's physical processes. Do you understand the way it works well enough to keep all its systems in operation? Can you make your kidneys function? Can you control the removal of waste? Are you conscious of the blood flow through your arteries, or the fact that you are losing a hundred thousand skin cells a minute?

John Boehner

We can continue to make significant strides in the scientific community by exploring new stem cell research methods that do not include destroying human embryos.

John Boehner

Stem cell research must be carried out in an ethical manner in a way that respects the sanctity of human life.

Aaron D. O'Connell

We talk about quantum weirdness and things being in two places at once, but it all involves atoms and molecules, stuff we don't normally interact with.

Johannes Stark

It is more likely that more than a century will pass before we know the structure of the chemical atoms as thoroughly as we do our solar system.

John Dalton

Matter, though divisible in an extreme degree, is nevertheless not infinitely divisible. That is, there must be some point beyond which we cannot go in the division of matter. ... I have chosen the word “atom” to signify these ultimate particles.

Ron Somers

It is really about trust and mutual respect. It is much more than just atoms and nuclear energy.

John Smith

How comes it to pass, if they be only moved by chance and accident, that such regular mutations and generations should be begotten by a fortuitous concourse of atoms.

Niels Bohr

When it comes to atoms, language can be used only as in poetry.

Michio Kaku

Physicists are made of atoms. A physicist is an attempt by an atom to understand itself.

Richard P. Feynman

What goes on inside a star is better understood than one might guess from the difficulty of having to look at a little dot of light through a telescope, because we can calculate what the atoms in the stars should do in most circumstances.

Martin Rees

If we do find ET, we will at least have something in common with them. They may live on planet Zog and have seven tentacles, but they will be made of the same kinds of atoms as us. If they have eyes, they will gaze out on the same cosmos as we do. They will, like us, trace their origins back to a 'Big Bang' 13.8 billion years ago.
