Quotation Quotes (8 quotes)

A quotation without a reference is like a geological specimen of unknown locality.

Every book is a quotation; and every house is a quotation out of all forests and mines and stone-quarries; and every man is a quotation from all his ancestors.

It has just occurred to me to ask if you are familiar with Lissajous’ experiments. I know nothing about them except what I found in Flammarion’s great “Astronomie Populaire.” One extraordinary chapter on numbers gives diagrams of the vibrations of harmonics—showing their singular relation to the geometrical designs of crystal-formation;—and the chapter is aptly closed by the Pythagorian quotation: Ἀεὶ ὁ θεὸς ὁ μέγας γεωμετρεῖ—“God geometrizes everywhere.” … I should imagine that the geometry of a fine opera would—were the vibrations outlined in similar fashion—offer a network of designs which for intricate beauty would double discount the arabesque of the Alhambra.
In letter to H.E. Krehbiel (1887), collected in Elizabeth Bisland The Writings of Lafcadio Hearn (1922), Vol. 14, 8.
Science quotes on:  |  Beauty (239)  |  Crystal (53)  |  Design (113)  |  Diagram (13)  |  Camille Flammarion (5)  |  Formation (58)  |  Geometry (215)  |  Harmonic (4)  |  Intricate (21)  |  Network (13)  |  Opera (3)  |  Pythagoras (34)  |  Relation (149)  |  Vibration (15)

It is a good thing from an uneducated man to read books of quotations.
In My Early Life: A Roving Commission (1930, 1987), 116.
Science quotes on:  |  Book (257)  |  Good (345)  |  Read (144)  |  Uneducated (5)

It may be appropriate to quote a statement of Poincare, who said (partly in jest no doubt) that there must be something mysterious about the normal law since mathematicians think it is a law of nature whereas physicists are convinced that it is a mathematical theorem.
Quoted in Mark Kac, Statistical Independence in Probability, Analysis and Number Theory (1959), 52.
Science quotes on:  |  Appropriateness (6)  |  Conviction (71)  |  Jest (4)  |  Law Of Nature (64)  |  Mathematician (364)  |  Mystery (151)  |  Physicist (160)  |  Statement (72)  |  Theorem (88)

It needs no dictionary of quotations to remind me that the eyes are the windows of the soul.
In Zuleika Dobson (1911), 54-55.
Science quotes on:  |  Dictionary (14)  |  Eye (218)  |  Need (283)  |  Remind (13)  |  Soul (163)  |  Window (40)

It was his [Leibnitz’s] love of method and order, and the conviction that such order and harmony existed in the real world, and that our success in understanding it depended upon the degree and order which we could attain in our own thoughts, that originally was probably nothing more than a habit which by degrees grew into a formal rule.* This habit was acquired by early occupation with legal and mathematical questions. We have seen how the theory of combinations and arrangements of elements had a special interest for him. We also saw how mathematical calculations served him as a type and model of clear and orderly reasoning, and how he tried to introduce method and system into logical discussions, by reducing to a small number of terms the multitude of compound notions he had to deal with. This tendency increased in strength, and even in those early years he elaborated the idea of a general arithmetic, with a universal language of symbols, or a characteristic which would be applicable to all reasoning processes, and reduce philosophical investigations to that simplicity and certainty which the use of algebraic symbols had introduced into mathematics.
A mental attitude such as this is always highly favorable for mathematical as well as for philosophical investigations. Wherever progress depends upon precision and clearness of thought, and wherever such can be gained by reducing a variety of investigations to a general method, by bringing a multitude of notions under a common term or symbol, it proves inestimable. It necessarily imports the special qualities of number—viz., their continuity, infinity and infinite divisibility—like mathematical quantities—and destroys the notion that irreconcilable contrasts exist in nature, or gaps which cannot be bridged over. Thus, in his letter to Arnaud, Leibnitz expresses it as his opinion that geometry, or the philosophy of space, forms a step to the philosophy of motion—i.e., of corporeal things—and the philosophy of motion a step to the philosophy of mind.

Carl Sagan Thumbnail In science it often happens that scientists say, 'You know that's a really good argument; my position is mistaken,' and then they would actually change their minds and you never hear that old view from them again. They really do it. It doesn't happen as often as it should, because scientists are human and change is sometimes painful. But it happens every day. I cannot recall the last time something like that happened in politics or religion. (1987) -- Carl Sagan
