THE PHYSICS PHILOSOPHY

Philosophy is written in that great book which ever lies before our eyes. I mean the Universe. But we cannot understand it if we do not learn the language and grasp the symbols in which it its written. This book is written in the mathematical language . . . without whose help it is impossible to comprehend a single word of it, without which one wonders in vain through a dark labyrinth.

GALILEO GALILEI (1564   1642) matematikan dan fisikawan dan astronomer Italia [ Foundation of Physics ]

It is not from Space that I must seek my dignity, but from the government of my thought. I shall have no more if I posses Worlds. By Space the Universe encompasses and swallows me up like an atom; by thought I comprehend the World.

BLAISE PASCAL (1623   1662) filsuf dan matematikan dan fisikawan Perancis [ Pensées ]

God is able to create particles of matter of several sizes and figures . . . and perhaps of different densities and forces, and thereby to vary the laws's of Nature, and make Worlds of several sorts in several parts of the Universe. At least, I see nothing of contradiction on all this.

SIR ISAAC NEWTON (1642   1727) matematikan dan fisikawan Inggris [ Optics ]

When you can not measure what are you speaking about, when you can not express it in terms of numbers, your knowledge is of a meager, imperceptible, and unsatisfactory kind. It may be the begining of knowledge, but you have barely, scarcely, and hardly in your thoughts, advanced to the stage of measurable and expressible information, whatever the matter may be . . . Our knowledge is satisfactory only . . . when we can express it in terms of numbers.

SIR WILLIAM THOMSON 'LORD' KELVIN (1824   1907) matematikan dan fisikawan Inggris [ The Math ]

The human mind is not capable of grasping the Universe. We are like a little child entering a huge library. The wall are covered to the ceilings with books in many different tongues. The child knows that someone must have written these books. It does not know who or how. It does not understand the languages in which they are written. But the child notes a definite plan in the arrangement of the books, a mysterious order which it does not comprehend, but only dimly suspects.

Master Cosmologist    ALBERT EINSTEIN (1879   1955) fisikawan dan kosmologiwan Jerman   AS [ Ideas and Opinions ]

Why did the Universe start out with so nearly the critical rate of expansion that separates models that recollapse from those that go on expanding forefer, so that even now, ten thousand million years later, it is still expanding at nearly the critical rate? If the rate of expansion one second after the big bang had been smaller by even one part in a hundred thousand million million, the Universe would have recollapsed before it ever reached its present size.
