"School reformers must turn their attention from structural changes, such as curricular alteration and modification in the physical environment, and address themselves to the nettlesome issue of teacher quality. Reform efforts must break the traditional patterns of limited professional stature, low wage structures, and inadequate professional commitment."

"Understanding what and why did not work may be more instructive than celebrating our successes." (p. 28)

"But anything that can be called "rigor" is lost exactly where the things become interesting and non trivial". (p. 31)

"But `the physical level of rigor' is higher on certainty than the logical one, since reproducible experiments are more reliable than anybody's, be it Hilbert's, Einstein's or Gödel's intuition"

"Reason is a powerful-but nevertheless limited-tool."

---Noson S. Yanofsky, "The Outer Limits of Reason", p. 352.

"André Weil once told to me (in private) that rigor is like a parking lot in Chicago, and axiomatics is the big light at the very center. As long as you stand below the light, you have a small chance of getting robbed, but as you venture to the dark edges, it becomes less and less safe, but much more interesting."

"Thers is this wonderful iconoclast at Rutgers, Doron Zeilberger, who says that our mathematics is the result of a random walk, by which he means whatWEcall mathematics. Likewise, I think, for the sciences."

"I have Doron Zeilberger for my number theory class this semester! .... He hates proofs, and thinks that if some conjecture is true for the first 1000 cases that's proof enough"

"...he is not a complete nut ..."

"...That's pretty much verbatim what he's told our class. If he's more subtle he hasn't let on..."

"...In the audience was a "goblin" with gleaming brilliant eyes: Michael Kiessling, he told me with contagious enthusisam his "amours de jeunesse" (young loves) for plasma physics, ...""... -What, Vladimir Scheffer works here!!

-Yes, he has been here for ages. Why, Cédric, you know his work?

-But of course, I gave a Bourbaki seminar on his famous theorem about the existence of paradoxical solutions of Euler's equation ... I must meet him!"[...One page later] "After two or three general phrases, he stopped abruptly, saying that he must go home, since he uses public transportation, and what with the snow it is very slippery ... and `my journey is rather long, and' .... The end of the meeting [with Scheffer] passed by him stating all the good reasons why he must take his leave. The mathematical discussion lasted five minutes, during which I learned nothing. To say that this is the man behind the most surprising theorem in the whole theory of fluid mechanics! This is a living proof that that one can be a superior mind yet a poor communicator.

When I returned to Joel [Lebowitz], I told him about my meeting [with Scheffer] and regretted that it only lasted five minutes.

"It is a bit challenging to talk about cluster algebras. It is still a young theory, depending on how you define the beginning of life. It was conceived nine years ago, appeared in preprint form eight years ago, and the first official publication was seven years ago. It is still young, but it grew faster than our wildest expectations."

"...It is a very simple dynamical system, ..., and what was surprising is that it appears in so many places, including mirror symmetry in string theory."

"Q. (from audience): Can you elaborate on the connection [of cluster algebras] to mirror symmetry?

A. (from speaker AZ): No [laugh]. I hope to learn it one day, but it is still mysterious to me."

"On Sept. 5, 2006, it was exactly one hundred years after the tragic death of my great hero, Ludwig Boltzmann, so I decided to go on a pilgrimage to the Vienna cemetery where he is buried. I got lost, so I asked some strangers, "is there a map somewhere?". Then they asked me, "Whose grave are you looking for?". So I said "Boltzmann", and then they replied "Ah, S=klog(W)", it is that way". I realized that S=klog(W) is like a secret password.

"However the machine would permit us to test the hypothesis for any special value of n. We could carry out such tests for a sequence of consecutive values n=2,3,.. up to, say, n=100. If the result of at least one test were negative, the hypothesis would prove to be false; otherwise our confidence in the hypothesis would increase, and we should feel encouraged to attempt establishing the hypothesis (by means of a normal mathematical proof), instead of trying to construct a counterexample."

---Alfred Tarski (1948) [Contributed by David John Wilson]

Remark by DZ: There are many cases where checking it for one hundred values (or one thousand, or whatever, it depends on the problem, and sometimes ONE case suffices) constitutes a perfectly rigorous proof. If the finite number of cases that needs to be checked is too large, then checking it for a random large number of values would be what I call a

"You can keep counting forever. The answer is infinity. But, quite frankly, I don't think I ever liked it. I always found something repulsive about it.

I prefer finite mathematics much more than infinite mathematics. I think that it is much more natural, much more appealing and the theory is much more beautiful. It is very concrete. It is something that you can touch and something you can feel and something to relate to.

Infinity mathematics, to me, is something that is meaningless, because it is abstract nonsense."

"The standard model gives us an accuracy of ten decimal digits, this is an amazing success that has never been achieved before in science."

"Newton's theory is not `not right', it just does not cover all distances. Contrary to popular belief, theories in science are not proven wrong, they are just replaced by more complete and convenient theories. To sound provocative, even the geocentric theory was never "proven" wrong, it is just not as convenient as the heliocentric theory, since it requires endless epicycles."

Christos Papadimitriou once said that the theory of NP-hardness is the largest intellectual export of CS to Math and Science. And indeed when I checked google scholar, I found 2000 titles mentioning "NP" inphysics and chemistry alone. This means that science has adopted this notion and use it to demonstrate structural nastiness.

The fact that a problem is NP-complete does not make it go away.

The Theory of complexity has given new insight to basic concepts that engaged philosophers for millenia: Learning, Proof, Randomness, Knowledge, and Secret.

"Most current mathematical research, since the 60s, is devoted to fancy situations: it brings solutions which nobody understands to questions nobody asked. Nevertheless, those who bring these solutions are called distinguished by the academic community. This word by itself gives a measure of the social distance: real life mathematics do not require distinguished mathematicians. On the contrary, it requires barbarians: people willing to fight, to conquer, to build, to understand, with no predetermined idea about which tool should be used. We, at SCM, are not yet barbarians, but we are working on this. Of course, it takes some time, due to our earlier education. In academic life, people have specific ambitions, and customer satisfaction is not one of these ambitions. They want to be recognized, to obtain some notoriety, to be published and quoted, to get prizes and honors. We, at SCM, live on the service we give to our customers. And we remember what Thomas Grey wrote in 1732 (Elegy in a churchyard): The paths of glory lead but to the grave."

--Shalosh B. EkhadIt is a common public relations gimmick to give the entire credit for the solution of famous problems to the one mathematician who is responsible for the last step.

It would probably be counterproductive to let it be known that behind every "genius" there lurks a beehive of research mathematicians who gradually built up to the "final" step in seemingly pointless research papers. And it would be fatal to let it be known that the showcase problems of mathematics are of little or no interest for the progress of mathematics. We all know that they are dead ends, curiosities, good only as confirmation of the effectiveness of theory. What mathematicians privately celebrate when one of their showcase problems is solved is Polya's adage : "no problem is ever solved directly".

For supposing the proposition [R(q);q] were provable, it would also be correct; but that means, as has been said, that q would belong to K, i.e. \neg Bew[R(q);q] would also hold good, in contradiction to our initial assumption. If, in the contrary, the negation of [R(q);q] were provable, then \neg {q \in K}, i.e. Bew[R(q);q] would hold good. [R(q);q] would then be provable at the same time as its negation, which again is impossible.''
