Quotes in science
The great book of nature is written in mathematical symbols.
In science, 'fact' can only mean 'confirmed to such a degree that it would be perverse to withhold provisional assent.' I suppose that apples might start to rise tomorrow, but the possibility does not merit equal time in physics classrooms.
The most important scientific revolutions all include, as their only common feature, the dethronement of human arrogance from one pedestal after another of previous convictions about our centrality in the cosmos.
There are in fact two things, science and opinion; the former begets knowledge, the latter ignorance.
It is an error to imagine that evolution signifies a constant tendency to increased perfection. That process undoubtedly involves a constant remodelling of the organism in adaptation to new conditions; but it depends on the nature of those conditions whether the directions of the modifications effected shall be upward or downward.
Science ... warns me to be careful how I adopt a view which jumps with my preconceptions, and to require stronger evidence for such belief than for one to which I was previously hostile. My business is to teach my aspirations to conform themselves to fact, not to try and make facts harmonize with my aspirations.
Science is nothing but trained and organized common sense, differing from the latter only as a veteran may differ from a raw recruit: and its methods differ from those of common sense only as far as the guardsman's cut and thrust differ from the manner in which a savage wields his club.
The great tragedy of Science - the slaying of a beautiful hypothesis by an ugly fact.
Our scientific power has outrun our spiritual power. We have guided missiles and misguided men.
It's important to distinguish well-conducted from poorly conducted research, and to understand the outcome variables in a given investigation. For example, if someone were to announce that studies have shown traditional classroom discipline techniques are 'effective,' our immediate response should be to ask, 'Effective at what? Promoting meaningful learning? Concern for others? Or merely eliciting short-term obedience?' Empirical findings can come from rigorously conducted scientific studies but still be of limited value; everything depends on the objectives that informed the research.
