On Art: Poetry and Mathematics II

"The true spirit of delight, the exaltation...which is the touchstone of the highest excellence, is to be found in mathematics as surely as in poetry."  (Bertrand Russell, “Mysticism and Logic”, 1917)

"Mathematics is one component of any plan for liberal education. Mother of all the sciences, it is a builder of the imagination, a weaver of patterns of sheer thought, an intuitive dreamer, a poet. The study of mathematics cannot be replaced by any other activity that will train and develop man's purely logical faculties to the same level of rationality." (Cletus O Oakley, "Mathematics", The American Mathematical Monthly, 1949)

"Mathematics in this sense is a form of poetry, which has the same relation to the prose of practical mathematics as poetry has to prose in any other language. The element of poetry, the delight of exploring the medium for its own sake, is an essential ingredient in the creative process." (Jacob Bronowski, "Science and Human Values", 1956)

"Whatever the ins and outs of poetry, one thing is clear: the manner of expression - notation - is fundamental. It is the same with mathematics - not in the aesthetic sense that the beauty of mathematics is tied up with how it is expressed - but in the sense that mathematical truths are revealed, exploited and developed by various notational innovations." (James R Brown, “Philosophy of Mathematics”, 1999)

"Mathematicians have always appreciated clever notations; but symbolism is usually seen as a tool - it's what the tool does that we really care about. Fair enough. But if we want a richer appreciation of mathematics, we should focus some of our energy on this remarkable tool - notation. Besides mathematics, poetry alone works wonders with it." (James R Brown, “Philosophy of Mathematics”, 1999)

"[...] mathematics bears on poetry not only by analogy, but directly through metrics. Metrics is the science of poetry, and it would be healthy for poetry if that science were more widely and astutely studied." (Kurt Brown, “The Measured Word: On Poetry and Science”, 2001)

"What could mathematics and poetry share, except that the mention of either one is sometimes enough to bring an uneasy chill into a conversation? [...] Both fields use analogies - comparisons of all sorts - to explain things, to express unknown or unknowable concepts, and to teach." (Marcia Birken & Anne C Coon, “Discovering Patterns in Mathematics and Poetry”, 2008)

"There is nothing as dreamy and poetic, nothing as radical, subversive, and psychedelic, as mathematics. It is every bit as mind blowing as cosmology or physics (mathematicians conceived of black holes long before astronomers actually found any), and allows more freedom of expression than poetry, art, or music (which depends heavily on properties of the physical universe). Mathematics is the purest of the arts, as well as the most misunderstood." (Paul Lockhart, "A Mathematician's Lament", 2009)

"You do not study mathematics because it helps you build a bridge. You study mathematics because it is the poetry of the universe. Its beauty transcends mere things." (Jonathan D Farley)

"Proofs are to mathematics what spelling is to poetry. Mathematical works do consist of proofs, just as poems do consist of characters." (Vladimir Arnold)

5 Books 10 Quotes I: Mathematics in Its Creation

Walter W Sawyer, "What is Calculus About?”, 1961
"In mathematics, a certain surprising thing happens again and again. Someone poses a simple question, a question so simple that it seems no useful result can come from answering it. And yet it turns out that  the answer opens the door to all kinds of interesting developments, and  gives great power to the person who understands it."


"Mathematics also is an exploration. As we push out further, we meet new and unexpected situations and we have to revise our ideas. Rules we have used, theorems we have proved turn out to have unforeseen weaknesses."

Ian Stewart, "In Pursuit of the Unknown", 2012
“Equations have hidden powers. They reveal the innermost secrets of nature. […] The power of equations lies in the philosophically difficult correspondence between mathematics, a collective creation of human minds, and an external physical reality. Equations model deep patterns in the outside world. By learning to value equations, and to read the stories they tell, we can uncover vital features of the world around us.”
“There are two kinds of equations in mathematics, which on the surface look very similar. One kind presents relations between various mathematical quantities: the task is to prove the equation is true. The other kind provides information about an unknown quantity, and the mathematician’s task is to solve it - to make the unknown known.”

Philip J Davis et al, "The Mathematical Experience", 1995
“Where is the place of mathematics? Where does it exist? On the printed page, of course, and prior to printing, on tablets or on papyri. Here is a mathematical book - take it
in your hand; you have a palpable record of mathematics as an intellectual endeavor. But first it must exist in people's minds, for a shelf of books doesn't create mathematics.”


“The definition of mathematics changes. Each generation and each thoughtful mathematician within a generation formulates a definition according to his lights.”

David Ruelle, "Chance and Chaos", 1991
"Because mathematical proofs are long, they are also difficult to invent. One has to construct, without making any mistakes, long chains of assertions, and see what one is doing, see where one is going. To see means to be able to guess what is true and what is false, what is useful and what is not. To see means to have a feeling for which definitions one should introduce, and what the key assertions are that will allow one to develop a theory in a natural manner."

"Mathematics has deep unity. More than a collection of separate theories such as set theory, topology, and algebra, each with its own basic assumptions, mathematics is a unified whole. Mathematics is a great  kingdom, and that kingdom belongs to those who see."

James R Brown,"Philosophy of Mathematics", 1999
"Whatever the ins and outs of poetry, one thing is clear: the manner of expression - notation - is fundamental. It is the same with mathematics - not in the aesthetic sense that the beauty of mathematics is tied up with how it is expressed - but in the sense that mathematical truths are revealed, exploited and developed by various notational innovations."

“In sum, these are a few of the ingredients in the mathematical image:
(1) Mathematical results are certain
(2) Mathematics is objective
(3) Proofs are essential
(4) Diagrams are psychologically useful, but prove nothing
(5) Diagrams can even be misleading
(6) Mathematics is wedded to classical logic
(7) Mathematics is independent of sense experience
(8) The history of mathematics is cumulative
(9) Computer proofs are merely long and complicated regular proofs
(10) Some mathematical problems are unsolvable in principle”

“Teaching is not about how we see things, it is about how children see things.” (Kavita B Ghosh)

"Children must be taught how to think, not what to think." (Margaret Mead)

“A teacher who cannot explain any abstract subject to a child does not himself thoroughly understand his subject; if he does not attempt to break down his knowledge to fit the child's mind, he does not understand teaching.” (Fulton J. Sheen, “Life Is Worth Living”)

"When you want to teach children to think, you begin by treating them seriously when they are little, giving them responsibilities, talking to them candidly, providing privacy and solitude for them, and making them readers and thinkers of significant thoughts from the beginning. That’s if you want to teach them to think." (Bertrand Russell)

“Everyday classroom teaching is not what children will remember, but how you made a difference in their lives.” (Nita Ambani)

"The object of teaching a child is to enable him to get along without a teacher." (Elbert Hubbard)

"Failure is so much more interesting because you learn from it. That's what we should be teaching children at school, that being successful the first time, there's nothing in it. There's no interest, you learn nothing actually." (Sir James Dyson)

"The teacher, if indeed wise, does not bid you to enter the house of their wisdom, but leads you to the threshold of your own mind." (Kahil Gibran)

“A great teacher is not simply one who imparts knowledge to his students but is one who awakens their interest in the subject and makes them eager to pursue it for themselves. An outstanding teacher is a spark plug, not a fuel line.” (Norman J Berrill)

"Great teachers see challenging students as a reason to try that much harder." (Todd Whitaker)

"Great teachers have high expectations for their students, but higher expectations for themselves."  (Todd Whitaker)

"You do not have to be kind to be a teacher, but you do have to be kind to be a good one." (Todd Whitaker)

"The true teacher defends his pupils against his own personal influence." (Amos B Alcott)

"A good teacher protects his pupils from his own influence."  (Bruce Lee)

"Great teachers do not act important; they make their students feel important."    (Todd Whitaker)

"Perhaps the most valuable result of all education is the ability to make yourself do the thing you have to do, when it ought to be done, whether you like it or not; it is the first lesson that ought to be learned; and however early a man's training begins, it is probably the last lesson that he learns thoroughly." (Thomas H Huxley)

(Henry A Rowland)

"A real education will not teach you to compete; it will teach you to co-operate. It will not teach you to fight and come first. It will teach you to be creative, to be loving, to be blissful without any comparison with the other." (Osho)

What is Mathematics not? - Part I

“Mathematics is not a book confined within a cover and bound between brazen clasps, whose contents it needs only patience to ransack; it is not a mine, whose treasures may take long to reduce into possession, but which fill only a limited number of veins and lodes; it is not a soil, whose fertility can be exhausted by the yield of successive harvests; it is not a continent or an ocean, whose area can be mapped out and its contour defined; it is as limitless as the space which it finds too narrow for its aspirations; its possibilities are as infinite as the worlds which are forever crowding in and multiplying upon the astronomer's gaze; it is incapable of being restricted within assigned boundaries or being reduced to definitions of permanent validity as the consciousness, the life, which seems to slumber in each monad, in every atom of matter, in each leaf and bud and cell and is forever ready to burst forth into new forms of vegetable and animal existence. “ (James J Sylvester, "The Educational Times", 1877)

“Mathematics is not the discoverer of laws, for it is not induction; neither is it the framer of theories, for it is not hypothesis; but it is the judge over both, and it is the arbiter to which each must refer its claims; and neither law can rule nor theory explain without the sanction of mathematics.” (Benjamin Peirce, “Linear Associative Algebra”, American Journal of Mathematics, Vol. 4, 1881)

"It has been argued that mathematics is not or, at least, not exclusively an end in itself; after all it should also be applied to reality. But how can this be done if mathematics consisted of definitions and analytic theorems deduced from them and we did not know whether these are valid in reality or not. One can argue here that of course one first has to convince oneself whether the axioms of a theory are valid in the area of reality to which the theory should be applied. In any case, such a statement requires a procedure which is outside logic.” (Ernst Zermelo, "Mathematische Logik - Vorlesungen gehalten von Prof. Dr. E. Zermelo zu Göttingen im S. S", 1908)

"Mathematics is not like a game whose tasks are determined by arbitrarily stipulated rules. Rather, it is a conceptual system possessing internal necessity that can only be so and by no means otherwise.” (David Hilbert, “Natur und Mathematisches Erkennen”, 1919–20)

“[…] mathematics is not, never was, and never will be, anything more than a particular kind of language, a sort of shorthand of thought and reasoning. The purpose of it is to cut across the complicated meanderings of long trains of reasoning with a bold rapidity that is unknown to the mediaeval slowness of the syllogisms expressed in our words.” (Charles Nordmann, "Einstein and the Universe", 1922)

“Mathematics is not a world empire where one man can exert a dominating influence over work along all the lines, but it is continually splitting up into self-determining republics.” (Geroge A Miller, “Felix Klein and the History of Modern Mathematics”, 1927)

“Mathematics is not a complete and perfected body of doctrine which one goes to seek in the scriptures whenever one has need of it.” (Karl K Darrow, “The Renaissance of Physics”, 1936)

“[…] mathematics is not an empirical science, or at least that it is practiced in a manner which differs in several decisive respects from the techniques of the empirical sciences.” (John von Neumann, “The Mathematician“, Works of the Mind Vol. I, 1947) [Link]
