Hypothesis Quotes
-
In thermodynamics as well as in other branches of molecular physics , the laws of phenomena have to a certain extent been anticipated, and their investigation facilitated, by the aid of hypotheses as to occult molecular structures and motions with which such phenomena are assumed to be connected. The hypothesis which has answered that purpose in the case of thermodynamics, is called that of "molecular vortices," or otherwise, the "centrifugal theory of elasticity.
William John Macquorn Rankine

The results serve to disprove the tetranucleotide hypothesis. It is, however, noteworthy-whether this is more than accidental, cannot yet be said-that in all desoxypentose nucleic acids examined thus far the molar ratios of total purines to total pyrimidines, and also of adenine to thymine and of guanine to cytosine, were not far from 1.

Hypothesis is a toll which can cause trouble if not used properly. We must be ready to abandon our hypothesis as soon as it is shown to be inconsistent with the facts.
William Ian Beardmore Beveridge
-
All interpretations made by a scientist are hypotheses, and all hypotheses are tentative. They must forever be tested and they must be revised if found to be unsatisfactory. Hence, a change of mind in a scientist, and particularly in a great scientist, is not only not a sign of weakness but rather evidence for continuing attention to the respective problem and an ability to test the hypothesis again and again.
Ernst Mayr

Darwin and his successors have railed against the fallacy of confusing the current utility of a trait with the reason the trait evolved. For example, Darwin argued that skull sutures in mammals did not evolve because they facilitate live birth; the sutures were in place well before live birth evolved. Checking the chronological order in which different traits evolved in a lineage is one way to test an adaptive hypothesis; the fact of common ancestry is what makes that checking possible.
Elliott Sober
-
The psycho-physiological hypothesis is both inductively and deductively the sine qua non of the science of psychology.
Boris Sidis

The most startling result of Faraday's Law is perhaps this. If we accept the hypothesis that the elementary substances are composed of atoms, we cannot avoid concluding that electricity also, positive as well as negative, is divided into definite elementary portions, which behave like atoms of electricity.
Hermann von Helmholtz
-
This constitution we designate by the word genotype. The word is entirely independent of any hypothesis; it is fact, not hypothesis that different zygotes arising by fertilisation can thereby have different qualities, that, even under quite similar conditions of life, phenotypically diverse individuals can develop.
Wilhelm Johannsen
-
Nature, my dear sir, is only a hypothesis
Raoul Dufy
-
Hypotheses are lullabies for teachers to sing their students to sleep.
Johann Wolfgang von Goethe
-
To be fertile in hypotheses is the first perquisite of creativity and to be willing to throw them away the moment experience contradicts them is the next.
William James
-
Nevertheless, as is a frequent occurrence in science, a general hypothesis was constructed from a few specific instances of a phenomenon.
Sidney Altman
