A Quote by Claude Bernard

Experiment is fundamentally only induced observation. — © Claude Bernard
Experiment is fundamentally only induced observation.
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.
Observation and experiment for gathering material, induction and deduction for elaborating it: these are are only good intellectual tools.
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.

A careful analysis of the process of observation in atomic physics has shown that the subatomic particles have no meaning as isolated entities, but can only be understood as interconnections between the preparation of an experiment and the subsequent measurement.
A rocket is an experiment; a star is an observation.
Fashions are the only induced epidemics, proving that epidemics can be induced by tradesmen.
In the philosophic sense, observation shows and experiment teaches.
The ultimate court of appeal is observation and experiment... not authority.
Men who have excessive faith in their theories or ideas are not only ill prepared for making discoveries; they also make very poor observations. Of necessity, they observe with a preconceived idea, and when they devise an experiment, they can see, in its results,only a confirmation of their theory. In this way they distort observation and often neglect very important facts because they do not further their aim.
Observation, reason, and experiment make up what we call the scientific method.
Observe, and in that observation there is neither the "observer" nor the "observed" - there is only observation taking place.
By no amount of reasoning can we altogether eliminate all contingency from our world. Moreover, pure speculation alone will not enable us to get a determinate picture of the existing world. We must eliminate some of the conflicting possibilities, and this can be brought about only by experiment and observation.
In the end, color combinations come down to our personal preferences, which we must discover through observation and experiment.
every short story is an experiment - what one must ask is not only, did it come off, but was it, as an experiment, worth making?
I have been induced to adopt this course by a desire that my readers should be taught to think as well as to experiment, and thus be qualified at an early part of their study to discriminate between the true and the false, and acquire the facts of the science without being mystified by its fictions.
