Salary Theorem
The less you know, the more you make.

Proof:
Postulate 1: Knowledge is Power.
Postulate 2: Time is Money.
As every engineer knows: Power = Work / Time
And since Knowledge = Power and Time = Money
It is therefore true that Knowledge = Work / Money .
Solving for Money, we get:
Money = Work / Knowledge
Thus, as Knowledge approaches zero, Money approaches infinity, regardless of the amount of Work done.

And adding on to that one...

As knowledge = 1 / ignorace
If ignorance is bliss, ignorance = bliss
so money = work / (1 / bliss)
money = work * bliss.

And because money is directly proportional to happiness, money can buy happiness.

(ok, so knowledge = 1/ ignorance is slightly pushing the logic...)

A wholly derivative (and terrible) joke:

A large hotel is packed full of engineers, mathematicians and physicists in preparation for a conference.

The night before the conference, a mathematician awakes to find his desk aflame and the room filling with smoke. He grabs his blanket to smother the flames, but has a sudden flash of insight â€” catching a stack of paper on fire, he runs up and down the hotel, depositing a lit sheet under every door. Satisfied, he pulls the fire alarm and exits.

Minutes later, the crowd is shivering outside the hotel as a half-dozen fire trucks spray down the exterior. Furious, the physicists begin to congregate around the mathematician, who is grinning broadly. "Why didn't you wake us up?" one shouts. "At least we might have isolated the singularity!"

"Or we could have formed a brigade!" chimes in an engineer, gesturing angrily at the unfazed mathematician. Drawing tighter and tighter, the engineers and physicists notice that, in fact, most of the mathematicians are either adamantly cheerful or murmuring peaceably among themselves. Livid with rage, the physicist whips his finger at the network of hoses and flashing lights, screaming "Can't you see what you've done? Why the hell are you smiling?!"

To which the mathematician replies: "Isn't it obvious? Contrary to popular opinion, generalizing the problem led to a more elegant solution!"

Yay metahumor!

An engineer, a physicist and a mathematician find themselves in an anecdote, indeed an anecdote quite similar to many that you have no doubt already heard.

After some observations and rough calculations the engineer realizes the situation and starts laughing.

A few minutes later the physicist understands too and chuckles to himself happily as he now has enough experimental evidence to publish a paper.

This leaves the mathematician somewhat perplexed, as he had observed right away that he was the subject of an anecdote, and deduced quite rapidly the presence of humour from similar anecdotes, but considers this anecdote to be too trivial a corollary to be significant, let alone funny.

Two serious errors. Shoddy premise and improper notation, unless it's a computer command algorithm. Just as it would be P sub a (Power sub absolute), it should be C sub a (Corruption sub absolute). His proof only defines two types of absolution.

eh...i don't see where he defined even one type of absolute value, or how subscript notation would be helpful at all, except to further the demonic cause of the people who like to use subscripts for everything.

Why didn't Newton discover group theory?

Because he wasn't Abel.

Why did the mathematician name his dog Cauchy?

Because he left a residue at every pole.

Anything that has the mathematician exclaiming "there is a solution!" and proceeding to stop caring entirely about the problem. Alternatively, he could respond to a numerical question with something like, "some number".

My apologies for being imprecise. I meant absolute x power= absolute x corruption. I will rewrite it in proof form.

Postulate 1: School is knowledge
Postulate 2: Knowledge is power
Postulate 3: Absolute power is absolute corruption (absolute x power = absolute x corruption)

Therefore
Power=Corruption (divided by absolute)
Knowledge=Corruption (Transitive property)
School=Corruption (Transitive property)

Posted: Tue Jun 19, 2007 5:24 am UTC
You cannot divide by absolute, since the modulus operator is precisely that, an operator. To remove the absolute, you would have to write
$power = \pm corruption$ or $\pm power = corruption$.

A computer scientist is standing holding a pair of suitcases in an airport baggage claim area. He is looking rather confused. A traveler asks if he's having trouble finding all of his luggage.
The computer scientist says "Yes, I'm supposed to have 2 bags, but I can't find the other one."
The traveler, now himself confused, states "But they're both right there. See? One, two."
The computer scientist says "No, no, no. Zero, one..."

...that makes even less sense. what i've been getting at is the obvious fact that two things which have the same norm/absolute value/whatever are not necessarily equal. i think it's time you abandoned this joke.

Posted: Tue Jun 19, 2007 6:11 pm UTC
I think he was treating absolute as a quantity, rather than an operator. "Absolute power," like "5 hectares of swampland," is simply a measurement, so if absolute power is absolute corruption, then presumably one can divide by this "absolute" quantity (which probably isn't zero) to show that power is corruption.

That said, equation-based jokes are almost always a stretch. Although I was pretty amused a few summers ago to see homophobic bumperstickers proclaim "man + woman > man + man," or something to that effect. Adding woman â€“ man to both sides gives an interesting position for the conservative right to hold.

And I know I've seen a bumper sticker which was presumably trying to get the same message across, but in fact, proclaims the incompatable equation "man + woman > woman + woman"

I got this in my e-mail this morning. Thought some of you here might enjoy it.

"Psst, c'mere," said the shifty-eyed man wearing a long black trenchcoat, as he beckoned me off the rainy street into a damp dark alley. I followed.

"What are you selling?" I asked.

"Geometrical algebra drugs."

"Huh!?"

"Stop right there," I interrupted. "I've never heard of inside-outers."

"Oh, man, you'll love 'em. Makes you feel like M.C. ever-lovin' Escher on a particularly weird day."

"Go on..."

"OK, your inside-outers, your arbitrary bilinear mappers, and here, heh, here are the best ones," he said, pulling out a large clear bottle of orange pills.

"What are those, then?" I asked.

"Givens transformers. They'll rotate you about more planes than you even knew existed."

"Sounds gross. What about those bilinear mappers?"

"There's a whole variety of them. Here's one you'll love -- they call it 'One Over Z' on the street. Take one of these little bad boys and you'll be on speaking terms with the Point at Infinity."

Gods alive, no wonder no one else uses it: it's an incorrect proof. |power| = |corruption| does not imply power = corruption, because it's possible that for any power, power = - corruption, in which case (as well as a variety of others) power != corruption.

edit: Not that anyone else pointed it out or anything...

Oh well, I guess it's to my credit that I care about Math.

power = - corruption if |corruption| < .5, power = corruption otherwise, for example. figure out more yourself.

I was using absolute as a value not as modulus. i.e. absolute(power)=absolute x power; not sqrt((power^2)).

i^ and k^ (meaning i hat and k hat) go to a party in the xy-plane. They wait in line for a while and then they finally make it up to the bouncer and he lets k^ in, no questions asked, but he stops i^ in his tracks. i^ says "hey, what's the big deal, you let my buddy k^ in no problem!" The bouncer looks at i^ and says "son, you're not normal."

A mathematician, physicist, and an engineer are asked to find the volume of a red sphere:

The mathematician looks at the sphere and then measures the circumference and then calculates the radius and uses that to calculate the volume.

The physicist looks at the sphere and then gets a graduated cylinder and fills it part way with water. He then submerges the sphere in the water and states that the volume of the sphere is equal to the displacement of the water.

The engineer takes the sphere and starts look at it all over, making sure that he sees the whole surface of the sphere. Then he pulls out a book of tables and starts flipping through it. He starts to get nervous as he nears the end of the book. When he finishes with the book, he pulls out another book of tables and keeps flipping through it. When he finishes with his second book he asks "Hey, do any of you have tables for red spheres?"

I had a professor tell me this story about a professor of his when he was in grad school:

The prof is working on a proof and comes to a conclusion and says that it is obvious that it is true. One of the students asks if it really is obvious. The prof stood there silent for 5 minutes thinking and finally said "It was obvious last night."

They all look out of the window and see something like this in a field:

The mathematician says "There is at least one cow here, which is brown on at least one side"
