From the dawn of exact knowledge to the present day, observation, experiment, and speculation have gone hand in hand; and, whenever science has halted or strayed from the right path, it has been, either because its votaries have been content with mere unverified or unverifiable speculation (and this is the commonest case, because observation and experiment are hard work, while speculation is amusing); or it has been, because the accumulation of details of observation has for a time excluded speculation.

Thomas Huxley

We must trust to nothing but facts: these are presented to us by nature and cannot deceive. We ought, in every instance, to submit our reasoning to the test of experiment, and never to search for truth but by the natural road of experiment and observation.

Antoine Lavoisier

Antoine Lavoisier

Science starts with preconception, with the common culture, and with common sense. It moves on to observation, is marked by the discovery of paradox, and is then concerned with the correction of preconception. It moves then to use these corrections for the designing of further observation and for more refined experiment. And as it moves along this course the nature of the evidence and experience that nourish it becomes more and more unfamiliar; it is not just the language that is strange [to common culture].

J. Robert Oppenheimer

Experiment - exercising to see the result. We planned Europa not as an experiment in this sense but as a work of art. Yet The Eye and the Ear was done as a consciously designed experiment. Not every avant-garde dealt with experiments and not every experiment equalled avant-garde.

Stefan Themerson

The philosophical question before us is, when we make an observation of our track in the past, does the result of our observation become real in the same sense that the final state would be defined if an outside observer were to make the observation?

Richard P. Feynman

You know how it is when you go to be the subject of a psychology experiment and nobody else shows up and you think maybe that's part of the experiment? I'm like that all the time.

Steven Wright

A rocket is an experiment; a star is an observation.

Jose Bergamin

Experiment is fundamentally only induced observation.

Claude Bernard

There is one experiment which I always like to try, because it proves something whichever way it goes. A solution of iodine in water is shaken with bone-black, filtered and tested with starch paste. If the colorless solution does not turn the starch blue, the experiment shows how completely charcoal extracts iodine from aqueous solution. If the starch turns blue, the experiment shows that the solution, though apparently colorless, still contains iodine which can be detected by means of a sensitive starch test.

Wilder Dwight Bancroft

The ultimate court of appeal is observation and experiment... not authority.

Thomas Huxley

Observation, reason, and experiment make up what we call the scientific method.

Richard P. Feynman

Drawing teaches habits of close observation that will always be useful.

Susanna Clarke

Sports teaches you character, it teaches you to play by the rules, it teaches you to know what it feels like to win and lose-it teaches you about life.

Billie Jean King

I love the values football can teach. It gives young people a sense of how to defer present gratification for future success, it teaches self-discipline, it teaches teamwork, it gives them a bonding experience that can be hard to find somewhere else, it teaches the ability to process large amounts of information and apply it in real time.
