The Quotes of Chairman Arthur P. Mattuck 18.063 Fall Term 1987 All quotes are kept in the file ~balamac/mattuck.txt (NFS). --------- ``Obviously'' inverse means I don't want to bother (9/18) Let's do this as a thought experiment. (9/18) ``Well-defined'' means something that seems to be a definition really is (9/21) That's a bijection because it obviously is (9/21) Some signed sum of some things (9/21) There are sets where you can't even get started (9/21) To pick k is to pick n-k (9/23) I'll go too fast anyway, but this way I'll have sympathy (9/23) Now, this formula is intuitively obvious (9/25) Different but pretty much the same (9/28) I'm making up notation as I go, but so what (9/28) Everything twiddles itself (9/28) Trivial: go home and stare at it for 3 hours until you're convinced (9/30) The margin of this blackboard is too small for the proof of this theorem (9/30) After working at it long enough to understand it, you should agree that it's trivial (9/30) Nobody in his right mind would write it this way [Mattuck just did] (9/30) It's useful since it can often be done (10/2) The answer is...This is solvable because...Why am I wearing a tie and jacket? (10/2) I don't deal with special cases (10/2) It's Fermatty (10/5) If they're fundamental, they will be used (10/5) He wasn't Russian, but he would be if he were alive today [Mattuck on Kant] (10/7) It has an irregular singular [vertex/vertices] (10/7) Pure math is divided into analysis, algebra, and topology. Never mind what they are, they're not important (10/14) Take it, pick it up, and let the rest hang down (10/14) I won't give you a transparent proof. I'll give you the most obscure proof I can find. (10/14) A tree which is not connected is a forest. (10/14) That's outside the scope of this course. That's in the next course, which you won't take. (10/19) This is a true fact, like all facts. (10/19) Nothing is harder than counting (10/21) You don't have to give a reason for it; you just know it (10/21) It's 4-dimensional space. All you need is 4 axes. (10/21) I have a feeling I must be a windbag, since my notes for this lecture consist of 4 lines, and [in 44 minutes] I've only covered 2. (10/21) That's indigo, a color no one's ever seen (10/21 Rec.) Back in the old days, in pre-history, I mean last century... (10/21) ``The finest mathematician in nonabelian hocus-pocus between the ages of 36 and 37'' (10/23) I guess a perfect magician can do anything (10/23) How many people don't know \omega is the cube-root of unity? That's a lie; I just told you. (10/26) I'd have to work a minute or two to say it better, but I'm sure I could. (10/26) I don't want to prove that. It's intuitively clear. Why don't we just talk about it for a minute? (Artin, 10/28) Call it "e" for "identity" (Artin, 10/28) K is an integer. I assume you know that by now (10/30) It's like the SAT: Congruence mon n is to the integers as "~" mon H is to any group. (10/30) I think you could do this as an exercise yourself. In fact, I don't know why I'm doing it. (10/30) It's undoing a definition, which is what all of mathematics is. (10/30) You'll use it in the next problem set. If that isn't applied mathematics I don't know what is. (10/30) If you work hard you should have corollaries (10/30) "P" is always a prime number. (11/2) 3 and 3 is 1, they don't make 6. Well, they do make 6, but it makes more sense if they make 1. (11/2) When something is beautiful and elegant, it is of no help in actual computation. (11/2) Beautiful but ineffective: I know some people like that. (11/2) It's empty, but you've got to put in something, otherwise no one knows it's there. (11/4) "F" isn't a function anymore. It's just the letter that comes after "e". (11/4) Since you're goo guys and I'm not... (11/6) Anybody not understand that? Too bad. (11/6) Proof by example. (11/9) Within 100 yards of here are the greatest Lie Algebraists in the world, when they're in their offices. (11/16)
