If we knew what it was we were doing, it would not be called research, would it?

The grand aim of all science is to cover the greatest number of empirical facts by logical deduction from the smallest number of hypotheses or axioms.

If you cannot question it, it's not science, it's propaganda.

The world's scientific communities cannot claim absolute truth, but they can fairly claim that they are closer than anyone else to genuine knowledge concerning their particular fields of study.

Not having all the information you need is never a satisfactory excuse for not starting the analysis.

We are all agreed that your theory is crazy. The question that divides us is whether it is crazy enough to have a chance of being correct.

Science is the organized skepticism in the reliability of expert opinion.

The most exciting phrase to hear in science, the one that heralds new discoveries, is not 'Eureka!' but 'That's funny...'

Science is not a body of facts but a method of inquiry - a way of being wrong with confidence rather than right with uncertainty.

Every brilliant scientific theory was once considered heresy. Progress requires the courage to challenge consensus.

The scientific method is humanity's most successful error-correction system - a perpetual machine for turning ignorance into understanding.

Science advances one funeral at a time, as old ideas die with those who hold them dear.

Data is not information, information is not knowledge, knowledge is not understanding, understanding is not wisdom.

The universe is under no obligation to make sense to you, but science is your best tool for trying to understand it anyway.

Scientific truth is not determined by who shouts loudest, but by which theory best survives attempts to destroy it.

The beauty of science is that it works whether you believe in it or not - reality is stubborn that way.

Science is the art of creating better and better approximations of reality while knowing we'll never reach the final answer.

Every measurement is an approximation; every theory is a temporary scaffold waiting for better evidence.

The purpose of science is not to open the door to infinite wisdom, but to set a limit to infinite error.
