My Design in this Book is not to explain the Properties of Light by Hypotheses, but to propose and prove them by Reason and Experiments: In order to which, I shall premise the following Definitions and Axioms.
Interpretation
Isaac Newton emphasizes the importance of using reason and experiments over mere speculation in understanding the properties of light.
In this quote, Isaac Newton articulates his scientific approach to understanding light, highlighting that the true nature of scientific inquiry relies on empirical evidence and logical reasoning rather than unfounded theories or hypotheses. He sets a foundation for his work by stating that he will establish definitions and principles that will guide his exploration, thereby underlining the importance of a structured methodology in the scientific process.
In practice
During a science seminar discussing the fundamentals of experimental physics.
The best and safest way of philosophising seems to be, first to enquire diligently into the properties of things, and to establish those properties by experiences [experiments] and then to proceed slowly to hypotheses for the explanation of them. For hypotheses should be employed only in explaining the properties of things, but not assumed in determining them; unless so far as they may furnish experiments.
Plato is my friend, Aristotle is my friend, but my greatest friend is truth.
His epitaph: Who, by vigor of mind almost divine, the motions and figures of the planets, the paths of comets, and the tides of the seas first demonstrated.
And from true lordship it follows that the true God is living, intelligent, and powerful; from the other perfections, that he is supreme, or supremely perfect. He is eternal and infinite, omnipotent and omniscient; that is, he endures from eternity to eternity; and he is present from infinity to infinity; he rules all things, and he knows all things that happen or can happen.
It is the weight, not numbers of experiments that is to be regarded.
Poetry is a kind of ingenious nonsense.
In fact, nothing in science as a whole has been more firmly established by interwoven factual information, or more illuminating than the universal occurrence of biological evolution. Further, few natural processes have been more convincingly explained than evolution by the theory of natural selection, or as it has been popularly called, Darwinism.
The sciences, even the best,-mathematics and astronomy,-are like sportsmen, who seize whatever prey offers, even without being able to make any use of it.
As Darwin himself was at pains to point out, natural selection is all about differential survival within species, not between them.
'Frankenstein' did not invent the fear of science; the novel found its audience because it dramatized anxieties that already existed. Although popular entertainment can, over the long run, shape public perceptions, it becomes popular in the first place only if it addresses preexisting hopes, fears, and fascinations.
After that cancellation [of the Superconducting Super Collider in Texas, after $2 billion had been spent on it], we physicists learned that we have to sing for our supper. ... The Cold War is over. You can't simply say "Russia!" to Congress, and they whip out their checkbook and say, "How much?" We have to tell the people why this atom-smasher is going to benefit their lives.
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.
