Johannes Kepler Quotes

In science we have to consider two things: power and circumstance.

Reason, observation, and experience; the holy trinity of science.

Science by itself is about numbers, and it's about measuring things. It's very important but it's very dry.

True science is never speculative; it employs hypotheses as suggesting points for inquiry, but it never adopts the hypotheses as though they were demonstrated propositions.

There are three principal means of acquiring knowledge available to us: observation of nature, reflection, and experimentation. Observation collects facts; reflection combines them; experimentation verifies the result of that combination.

Science walks forward on two feet, namely theory and experiment. Sometimes it is one foot which is put forward first, sometimes the other, but continuous progress is only made by the use of both.

We must have the real thing before we can have a science of a thing.

Experiment is the sole source of truth.

In the realm of scientific observation, luck is granted only to those who are prepared.

Science is a way of equipping yourself with the tools to interpret what happens in front of you.

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

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.

Every science consists in the coordination of facts; if the different observations were entirely isolated, there would be no science.

Facts are the air of scientists. Without them you can never fly.

The heart of science is measurement.

if the result confirms the hypothesis, then you've made a measurement. If the result is contrary to the hypothesis, then you've made a discovery.

No one believes an hypothesis except its originator but everyone believes an experiment except the experimenter. Most people are ready to believe something based on experiment but the experimenter knows the many little things that could have gone wrong in the experiment. For this reason the discoverer of a new fact seldom feels quite so confident of it as others do.

Experimental observations are only experience carefully planned in advance, and designed to form a secure basis of new knowledge.

Scientific method: There's a madness in the method.

We must conduct research and then accept the results. If they don't stand up to experimentation, Buddha's own words must be rejected.

Science walks forward on two feet, namely theory and experiment.

Scientific method, although in its more refined forms it may seem complicated, is in essence remarkably simply. It consists in observing such facts as will enable the observer to discover general laws governing facts of the kind in question. The two stages, first of observation, and second of inference to a law, are both essential, and each is susceptible of almost indefinite refinement. (1931)

Science is methodology. As a belief system it's disastrous.

An experiment is a question which science poses to Nature and a measurement is the recording of Nature's answer.

[Sherlock Holmes:] The temptation to form premature theories upon insufficient data is the bane of our profession.
