Hi ganesh and Bobby,

Reminds me of this sad tale sung by Peter, Paul and Mary, called Polly Von.

Its an Irish folk song about a young man who is hunting at twilight and mistakes his true love, who is taking shelter from the rain, for a swan. He shoots, and discovers that he's killed Polly.

So, alas and alack, it's 'Polly gone'.

Hi Bobby,

Maybe I'm a reincarnated version of me...

I've gathered a bit of a collection of secondhand LPs from garage sales and op shops and converted them to MP3s.

I remembered *Polly Von* and that it was on this record, so here's a photo I took of it (it's the last song):

Last time I saw one was in 1975 or so.

Mathematical joke:

Theorem: a cat has nine tails.

Proof:

No cat has eight tails. A cat has one tail more than no cat. Therefore, a cat has nine tails.

A physicist has been conducting experiments and has worked out a set of equations which seem to explain his data. He asks a mathematician to check them. A week later, the mathematician calls "I'm sorry, but your equations are complete nonsense." "But these equations accurately predict results of experiments. Are you sure they are completely wrong? "To be precise, they are not always a complete nonsense. But the only case in which they are true is the trivial one where the field is Archimedean..."

A mathematician has spent ten years trying to prove the Riemann hypothesis. Finally, he decides to sell his soul to the devil in exchange for a proof. The devil promises to deliver a proof in the four weeks. Half a year later, the devil shows up again - in a rather gloomy mood. "I'm sorry", he says. "I couldn't prove the hypothesis either. But" - and his face lightens up - "I think I found a really interesting lemma..."

Hope these are new:

Dictionary of Definitions of Terms Commonly Used in Math. lectures.

CLEARLY:

I don't want to write down all the "in- between" steps.

TRIVIAL:

If I have to show you how to do this, you're in the wrong class.

OBVIOUSLY:

I hope you weren't sleeping when we discussed this earlier, because I refuse to repeat it.

RECALL:

I shouldn't have to tell you this, but for those of you who erase your memory tapes after every test...

WLOG (Without Loss Of Generality):

I'm not about to do all the possible cases, so I'll do one and let you figure out the rest.

CHECK or CHECK FOR YOURSELF:

This is the boring part of the proof, so you can do it on your own time.

SKETCH OF A PROOF:

I couldn't verify all the details, so I'll break it down into the parts I couldn't prove.

HINT:

The hardest of several possible ways to do a proof.

SOFT PROOF:

One third less filling (of the page) than your regular proof, but it requires two extra years of course work just to understand the terms.

ELEGANT PROOF:

Requires no previous knowledge of the subject matter and is less than ten lines long.

SIMILARLY:

At least one line of the proof of this case is the same as before.

CANONICAL FORM:

4 out of 5 mathematicians surveyed recommended this as the final form for their students who choose to finish.

BY A PREVIOUS THEOREM:

I don't remember how it goes (come to think of it I'm not really sure we did this at all), but if I stated it right (or at all), then the rest of this follows.

TWO LINE PROOF:

I'll leave out everything but the conclusion, you can't question 'em if you can't see 'em.

BRIEFLY:

I'm running out of time, so I'll just write and talk faster.

LET'S TALK THROUGH IT:

I don't want to write it on the board lest I make a mistake.

PROCEED FORMALLY:

Manipulate symbols by the rules without any hint of their true meaning (popular in pure math courses).

QUANTIFY:

I can't find anything wrong with your proof except that it won't work if x is a moon of Jupiter.

PROOF OMITTED:

Trust me, It's true.

This poem was written by Jon Saxton (an author of math textbooks).

((12 + 144 + 20 + (3 * 4^(1/2))) / 7) + (5 * 11) = 9^2 + 0

Or for those who have trouble reading the poem:

A Dozen, a Gross and a Score,

plus three times the square root of four,

divided by seven, plus five times eleven,

equals nine squared and not a bit more.

A student wrote letter to his home:

Dear Dad!

$end it to me $oon,

Your $on.

A week later he received a letter from home:

Dear Son!

I kNOw that trigoNOmetry, astroNOmy, and ecoNOmics are eNOugh to keep even an hoNOr student busy. Do NOt forget that the pursuit of kNOwledge is a NOble task, and kNOw that NO one can ever learn eNOugh.

What is "pi"?

Mathematician: Pi is the ratio of circumference of a circle to its diameter.

Three men are in a hot-air balloon. Soon, they find themselves lost in a canyon somewhere. One of the three men says, "I've got an idea. We can call for help in this canyon and the echo will carry our voices far."

So he leans over the basket and yells out, "Hellllooooo! Where are we?" (They hear the echo several times).

Two minutes later they hear this echoing voice: "Hellllooooo! You're lost!!"

One of the men says, "That must be a mathematician." Puzzled, one of the other men asks, "Why do you say that?"

He replies: "For three reasons. (1) he took a long time to answer, (2) he was absolutely correct, and (3) his answer was absolutely useless."

*************************************************

Several students were asked the following problem:

Is it true that all odd integers are prime?

Well, the first student to try to do this says "hmmm... Well, 1 is prime, 3 is prime, 5 is prime, 7 is prime and by induction, we have that all the odd integers are prime."

The physics student then said, "I'm not sure of the validity of your proof, but I think I'll try to prove it by experiment." He continues, "Well, 1 is prime, 3 is prime, 5 is prime, 7 is prime, 9 is ... uh, 9 is an experimental error, 11 is prime, 13 is prime... Well, it seems that that all odd integers are prime."

The third student to try it was the engineering student, who responded, "Well, actually, I'm not sure of your answer either. Let's see... 1 is prime, 3 is prime, 5 is prime, 7 is prime, 9 is ..., 9 is ..., standard deviation, 11 is prime, 13 is prime... Well, it does seem that all odd integers are prime."

Not to be outdone, the computer science student comes along and says "Well, you guys sort'v got the right idea, but you'd end up taking too long doing it. I've just whipped up a program using a "do loop" to REALLY go and prove it..." He runs his computer program. The computer responds, "1 is prime, 1 is prime, 1 is prime, 1 is prime, 1 is prime...."
