I think it is not irreligion but a tidiness of mind, which rebels against the idea of permeating scientific research with a religious implication. - Arthur Eddington

I believe that there are 15,747,724,136,275,02,577,605,653,961,181,555,468,044,717,914,527,116,709,366,231,425,076,185,631,031,296 protons in the universe and the same number of electrons.

Materialism in its literal sense is long since dead. … It is … belief in the universal dominance of scientific law which is nowadays generally meant by materialism.

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.
