There was a time when we wanted to be told what an electron is. The question was never answered. No familiar conceptions… — Arthur Eddington Copy Share Image
Science is one thing, wisdom is another. Science is an edged tool, with which men play like children, and cut their own… — Arthur Eddington Copy Share Image
[When thinking about the new relativity and quantum theories] I have felt a homesickness for the paths of physical science where there… — Arthur Eddington Copy Share Image
There is no space without aether, and no aether which does not occupy space. — Arthur Eddington Copy Share Image
Unless the structure of the nucleus has a surprise in store for us, the conclusion seems plain — there is nothing in… — Arthur Eddington Copy Share Image
A hundred thousand million Stars make one Galaxy; A hundred thousand million Galaxies make one Universe. The figures may not be very… — Arthur Eddington Copy Share Image
When an investigator has developed a formula which gives a complete representation of the phenomena within a certain range, he may be… — Arthur Eddington Copy Share Image
But it is necessary to insist more strongly than usual that what I am putting before you is a model-the Bohr model… — Arthur Eddington Copy Share Image
In the most modern theories of physics probability seems to have replaced aether as "the nominative of the verb 'to undulate'." — Arthur Eddington Copy Share Image
Something unknown is doing we don't know what-that is what our theory amounts to. — Arthur Eddington Copy Share Image
For the truth of the conclusions of physical science, observation is the supreme Court of Appeal. — Arthur Eddington Copy Share Image
Electrical force is defined as something which causes motion of electrical charge; an electrical charge is something which exerts electric force. — Arthur Eddington Copy Share Image
There is only one law of Nature-the second law of thermodynamics-which recognises a distinction between past and future more profound than the… — Arthur Eddington Copy Share Image
Science is one thing, wisdom is another. Science is an edged tool, with which men play like children, and cut their own… — Arthur Eddington Copy Share Image
The helium which we handle must have been put together at some time and some place. We do not argue with the… — Arthur Eddington Copy Share Image
Our ultimate analysis of space leads us not to a "here" and a "there," but to an extension such as that which… — Arthur Eddington Copy Share Image
We have found that where science has progressed the farthest, the mind has but regained from nature that which the mind has… — Arthur Eddington Copy Share Image
Whether in the intellectual pursuits of science or in the mystical pursuits of the spirit, the light beckons ahead, and the purpose… — Arthur Eddington Copy Share Image
An electron is no more (and no less) hypothetical than a star. Nowadays we count electrons one by one in a Geiger… — Arthur Eddington Copy Share Image
The electron, as it leaves the atom, crystallises out of Schrödinger's mist like a genie emerging from his bottle. — Arthur Eddington Copy Share Image
The understanding between a non-technical writer and his reader is that he shall talk more or less like a human being and… — Arthur Eddington Copy Share Image
Man is slightly nearer to the atom than to the star. ... From his central position man can survey the grandest works… — Arthur Eddington Copy Share Image
If someone points out to you that your pet theory of the universe is in disagreement with Maxwell's equations-then so much the… — Arthur Eddington Copy Share Image
Our model of Nature should not be like a building-a handsome structure for the populace to admire, until in the course of… — Arthur Eddington Copy Share Image
Observation and theory get on best when they are mixed together, both helping one another in the pursuit of truth. It is a good… — Arthur Eddington Copy Share Image
Proof is an idol before which the mathematician tortures himself. — Arthur Eddington Copy Share Image
It is one thing for the human mind to extract from the phenomena of nature the laws which it has itself put into them;… — Arthur Eddington Copy Share Image
Don't believe the results of experiments until they're confirmed by theory. — Arthur Eddington Copy Share Image
Probably the simplest hypothesis... is that there may be a slow process of annihilation of matter. — Arthur Eddington Copy Share Image
There was a time when we wanted to be told what an electron is. The question was never answered. No familiar conceptions can be… — Arthur Eddington Copy Share Image
To the pure geometer the radius of curvature is an incidental characteristic - like the grin of the Cheshire cat. To the physicist it… — Arthur Eddington Copy Share Image
The universe will finally become a ball of radiation, becoming more and more rarified and passing into longer and longer wave-lengths. The longest waves… — Arthur Eddington Copy Share Image
Science is one thing, wisdom is another. Science is an edged tool, with which men play like children, and cut their own fingers. — Arthur Eddington Copy Share Image
We often think that when we have completed our study of one we know all about two, because 'two' is 'one and one.' We… — Arthur Eddington Copy Share Image
If your theory is found to be against the second law of thermodynamics I give you no hope; there is nothing for it but… — Arthur Eddington Copy Share Image
