„To understand the phenomena of the physical world it is necessary to know the equations which the symbols obey but not the nature of that which is being symbolised.“

— Arthur Stanley Eddington, Context: If to-day you ask a physicist what he has finally made out the æther or the electron to be, the answer will not be a description in terms of billiard balls or fly-wheels or anything concrete; he will point instead to a number of symbols and a set of mathematical equations which they satisfy. What do the symbols stand for? The mysterious reply is given that physics is indifferent to that; it has no means of probing beneath the symbolism. To understand the phenomena of the physical world it is necessary to know the equations which the symbols obey but not the nature of that which is being symbolised.... this newer outlook has modified the challenge from the material to the spiritual world.<!--III, p.30

„We do not know why we are born into the world, but we can try to find out what sort of a world it is — at least in its physical aspects.“

„What we now want is closer contact and better understanding between individuals and communities all over the earth, and the elimination of egoism and pride which is always prone to plunge the world into primeval barbarism and strife... Peace can only come as a natural consequence of universal enlightenment...“

— Nikola Tesla Serbian American inventor 1856 - 1943
Context: While I have not lost faith in its potentialities, my views have changed since. War can not be avoided until the physical cause for its recurrence is removed and this, in the last analysis, is the vast extent of the planet on which we live. Only though annihilation of distance in every respect, as the conveyance of intelligence, transport of passengers and supplies and transmission of energy will conditions be brought about some day, insuring permanency of friendly relations. What we now want most is closer contact and better understanding between individuals and communities all over the earth and the elimination of that fanatic devotion to exalted ideals of national egoism and pride, which is always prone to plunge the world into primeval barbarism and strife. No league or parliamentary act of any kind will ever prevent such a calamity. These are only new devices for putting the weak at the mercy of the strong.

„We can deduce, often, from one part of physics like the law of gravitation, a principle which turns out to be much more valid than the derivation.“

— Richard Feynman American theoretical physicist 1918 - 1988
Context: Now we have a problem. We can deduce, often, from one part of physics like the law of gravitation, a principle which turns out to be much more valid than the derivation. This doesn't happen in mathematics, that the theorems come out in places where they're not supposed to be! chapter 2, “ The Relation of Mathematics to Physics http://www.youtube.com/watch?v=M9ZYEb0Vf8U” referring to the law of conservation of angular momentum

„The alchemical tradition assumes that every physical art or science is a body of knowledge which exists only because it is ensouled by invisible powers and processes.“

— Manly P. Hall Canadian writer and mystic 1901 - 1990
Context: The alchemical tradition assumes that every physical art or science is a body of knowledge which exists only because it is ensouled by invisible powers and processes. Physical chemistry, as it is practiced in the modern world, is concerned principally with pharmaceutical or industrial research projects. It is confined within the boundaries of an all-pervading materialism, which binds labor to the advancement of physical objectives.
