• In any attempt to bridge the domains of experience belonging to the spiritual and physical sides of nature, time occupies the key position.

• Observation and theory get on best when they are mixed together, both helping one another in the pursuit of truth. It is a good rule not to put overmuch confidence in a theory until it has been confirmed by observation. I hope I shall not shock the experimental physicists too much if I add that it is also a good rule not to put overmuch confidence in the observational results that are put forward until they have been confirmed by theory.

• Every body continues in its state of rest or uniform motion in a straight line, except insofar as it doesn't.

• Unless the structure of the nucleus has a surprise in store for us, the conclusion seems plain — there is nothing in the whole system of laws of physics that cannot be deduced unambiguously from epistemological considerations.

• It is a primitive form of thought that things exist or do not exist.

  Form, Primitive

• There is only one law of Nature-the second law of thermodynamics-which recognises a distinction between past and future more profound than the difference of plus and minus. It stands aloof from all the rest. ... It opens up a new province of knowledge, namely, the study of organisation; and it is in connection with organisation that a direction of time-flow and a distinction between doing and undoing appears for the first time.

• Schrödinger's wave-mechanics is not a physical theory, but a dodge - and a very good dodge too.

• It is impossible to trap modern physics into predicting anything with perfect determinism because it deals with probabilities from the outset.

  Arthur Eddington

  Math, Perfect, Impossible

• Life would be stunted and narrow if we could feel no significance in the world around us beyond that which can be weighed and measured with the tools of the physicist or described by the metrical symbols of the mathematician.

  Arthur Eddington

  Nature, Would Be, Tools

• If your theory is found to be against the second law of thermodynamics I give you no hope; there is nothing for it but to collapse in deepest humiliation.

  Law, Giving, Found

• The helium which we handle must have been put together at some time and some place. We do not argue with the critic who urges that the stars are not hot enough for this process; we tell him to go and find a hotter place.

  Arthur Eddington

• We often think that when we have completed our study of one we know all about two, because 'two' is 'one and one.' We forget that we still have to make a study of 'and.'

  Arthur Eddington

  Thinking, Two, Study

• Our ultimate analysis of space leads us not to a "here" and a "there," but to an extension such as that which relates "here" and "there." To put the conclusion rather crudely-space is not a lot of points close together; it is a lot of distances interlocked.

  Arthur Eddington

  Distance, Science, Space

• A star is drawing on some vast reservoir of energy by means unknown to us. This reservoir can scarcely be other than the subatomic energy which, it is known exists abundantly in all matter; we sometimes dream that man will one day learn how to release it and use it for his service. The store is well nigh inexhaustible, if only it could be tapped. There is sufficient in the Sun to maintain its output of heat for 15 billion years.

  Arthur Eddington

• There once was a brainy baboon,
  Who always breathed down a bassoon,
  For he said, It appears
  That in billions of years
  I shall certainly hit on a tune.

  Arthur Eddington

• There was a time when we wanted to be told what an electron is. The question was never answered. No familiar conceptions can be woven around the electron; it belongs to the waiting list.

• Oh leave the Wise our measures to collate. One thing at least is certain, light has weight. One thing is certain and the rest debate. Light rays, when near the Sun, do not go straight.

  Arthur Eddington

• In the world of physics we watch a shadowgraph performance of the drama of familiar life. The shadow of my elbow rests on the shadow table as the shadow ink flows over the shadow paper. It is all symbolic, and as a symbol the physicist leaves it. ... The frank realisation that physical science is concerned with a world of shadows is one of the most significant of recent advances.

  Arthur Eddington

  Drama, Shadow, Ink

• To the pure geometer the radius of curvature is an incidental characteristic - like the grin of the Cheshire cat. To the physicist it is an indispensable characteristic. It would be going too far to say that to the physicist the cat is merely incidental to the grin. Physics is concerned with interrelatedness such as the interrelatedness of cats and grins. In this case the "cat without a grin" and the "grin without a cat" are equally set aside as purely mathematical phantasies.

  Arthur Eddington

  Cat, Math, Would Be

• The electron, as it leaves the atom, crystallises out of Schrodinger's mist like a genie emerging from his bottle.

• What we makes of the world must be largely dependent on the sense-organs that we happen to possess. How the world must have changed since the man came to rely on his eyes rather than his nose.

  Arthur Eddington

  Eye, Men, Noses
