Science Humor: A Wide Selection

[Njorl]

A large diplomatic delegation from Poland gets on a plane to go to a UN conference. The plane takes off normally, and everything seems fine during takeoff. Five minutes into the flight, however, the plane starts flying erratically, inverts, and crashes killing everyone onboard. The investigators analyzing the crash are dumbfounded since everything seemed to be in order with the aircraft. Eventually, they bring the problem to a contol engineer who immediately recognizes the problem: "It's simple really... you had poles in the right half of the plane!"

... let's see how many get it.

Even if they had worked around the poles, I'm sure there would have been nothing left but sum residue.

I don't get this one, and I didn't get the math party one... I'm sure its a pun of some sort, but it's escaping me.

Nope not a pun. e^x. is a constant function as far as a function of z is concerned.

Ah. So it wasn't funny.

A mathematician and an engineer are asked how they would make tea when all their cups were dirty. Engineer says: "I would clean the cups, then boil water and so on", mathematician says the same.
Afterwards they're asked again how to make tea, but with clean cups this time. Engineer says: "Hm? Well, I'd just boil water, throw tea leaves in, that's it." The mathematician says: "I would first dirty the cups and then apply solution 1."

Shortest mathematics joke:
\varepsilon < 0
with the even more excessive versions
\varepsilon \ll 0
and
\varepsilon \rightarrow - \infty

True story (from m8's school):

A kid @ GCSE Maths exam goes in gets on scribbling his answers down furiously.
The thing is though, he's answering the formulae-book that comes along with the question paper!

Do you know how he found out? Nearing the end of the exam he puts his hand up and calls one of the teachers over to him. He whispers to the teacher "...I'm stuck with this question...can u help?..."

This is a salesman that is in the train station and see that Einstein is there with a clock in his hand. Then the salesman thinks: Ah, so Einstein must have been doing some of the experiments that he explains in his books, those that try to demonstrate the constancy of c by measuring how it travels from the front to the back of a wagon and such.
Out of curiosity, the salesman goes to meet Einstein, and finds that he is very upset. The salesman asks to him: Hi, sir, have you been able to measure the length contraction of trains in your experiment?
Then Einstein answers: No, I had all prepared and was going to perform the experiment, but suddenly a lightning has fallen on the clock and now the damned doesn't work

"Do you know how fast you were driving, Sir ?", the cop asks him.

Heisenberg replies, "No, but I know where I am."

36 squared? The sum of (x + y + z) squared, of course.

I remember a story my dad used to tell at parties about a salesman and a mathematician riding next to each other on a train.

They passed a stockyard filled with cattle and the salesman exclaimed, “Wow, I’ve never seen so many cows in all my life! There must be thousands in that stockyard!”.

The mathematician turns to him and says, “Actually, there’s 7,458 cows in that stockyard.”

“How’d you count all of those cows, so fast?”, the salesman asked.

“Easy, I counted their legs and divided by 4”, replied the mathematician.

My dad was a little hard to read, since he always had such a serious look on his face no matter what, so people would look at him a little uncertain for a second, and finally reply, “Oh, that’s clever.” I guess that works whether he’s showing them a clever method of counting cows or telling them a really joke.

Well, me, I’m a just a kid, at the time. If the adults at the party can’t tell if he’s serious or joking, how am I supposed to tell. I had a tendency to repeat things like that around the neighborhood thinking I was showing off how smart I was. Which other kids in the neighborhood were quick sense was total rubbish.

And, hence the great cow counting challenge was staged. Unfortunately, we lived in the city. The only cow in the neighborhood was the picture of Elsie on the billboard outside the Borden dairy plant. No matter.

The smart-aleck girl from next door and I met (with the proper witnesses) down by the billboard ready to settle the best way of counting cows.

The kind of cute (in an intellectual sort of way) girl with the glasses from down the street yelled, “Go!”

Almost instantly, both of us contestants finished counting Elsie, with the smart aleck girl screaming “One!” just a thousandth of a second after I shouted “Zero!”

You see, the billboard only showed Elsie’s head, so there were no legs to count. And I ask you, who was closest to the right answer? What’s the purpose of a cow if not to give beef or milk and how can you get a steak from just a cow’s head. And how are you going to get milk from Elsie's head? Tell her jokes til milk comes out her nose? I’m thinking that’s going to take awhile, especially if all’s you know are math jokes.

Two physicists are flying in their hot air balloon and get lost. They drift low to the ground and see a man. One shouts out, "Where are we?" to which the man on the ground responds, "You're in a balloon."

The other physicist then asks, "Are you a mathematician?", to which the man on the ground answrs "Yes."

As they float off, the first physicist asks, "How did you know he was a mathematician?". The other responds, "Well, he was completely accurate, and completely useless."

There is this farmer who is having problems with his chickens. All of the sudden, they are all getting very sick and he doesn't know what is wrong with them. After trying all conventional means, he calls a biologist, a chemist, and a physicist to see if they can figure out what is wrong. So the biologist looks at the chickens, examines them a bit, and says he has no clue what could be wrong with them. Then the chemist takes some tests and makes some measurements, but he can't come to any conclusions either. So the physicist tries. He stands there and looks at the chickens for a long time without touching them or anything. Then all of the sudden he starts scribbling away in a notebook. Finally, after several gruesome calculations, he exclaims, 'I've got it! But it only works for spherical chickens in a vacuum.'

A hardware guy, a software guy and a sales rep of a big computer company are driving to a meeting, when the car suddenly stops. The software guy suggests that they shut down and restart, 'cause that usually fixes the problem. The hardware guy suggests they swap drivers. The sales rep decides that it's time to buy a new car.

A passing Linux programmer see the trouble and smashes all the glass in the car with his baseball bat. Before the stunned passengers can react he asks the driver to try starting the car again. The car starts up just fine this time.

There is a computer engineer, a psychologist and a genetic engineer in a room arguing about which occupation came first. The genetic engineer says 'I must have come first because God took a rib from Adam and made Eve and that takes genetics so God was a genetic engineer and I, therfore, came first'. The psychologist says 'No you are wrong. I came first because God took the world from chaos to peace and so God was a psychologist and so I came first'. The computer engineer just sits back smug with a grin on his face. 'Ahhh yes', he says,' Good points. But where go you think the chaos came from!'

There is a class room full of Alkali Metal ions being taught chemistry. Then outside the window a group of Halogen ions appear. The Alkali Metal ions go mad and bounce of the walls and the window. The teachers comment is 'Perhaps one of you gentlemen would mind telling me just what it is outside the window that you find so attractive...?'

There should be a picture here as well.

Took me ages to stop laughing after seeing it. I had only just learned about ionic bonding when I found it.

Quick limerick for you:

There once was a lady called bright,
Who's speed was faster than light,
She left one day,
In a relative way,
And returned on the previous night.

Question posed to a biologist:
What is the evolutionary advantage in having knees that bend forward instead of backwards…i.e. why don’t our knees bend the other way?
Answer:
“Bipedal animals that had backward-bending knees could only run backwards and they kept bumping into trees. That's why they became extinct.”

and asked what his future holds.

His Personal Psychic Advisor tells him:

"You are going to meet a beautiful young girl who

will want to know everything about you."

Your protein has NOT denaturated,
it is simply structurally ambivalent.
Your DNA has NOT degraded,
it is entropically exhuberant.
Your enzyme is NOT aggregated,
it is monomerically challenged.
Your peptide has NOT precipitated on the column,
it is merely elution reticent.
Your column resin is NOT compacting,
it is being spatially frugal.
Your BamHI does NOT have star activity,
it is simply expressing its individuality.
Your PCR products are NOT all mutant,
they are just indulging in unscheduled evolution.
Your tissue culture is NOT contaminated,
it is simply sharing living quarters.

Since I saw Linux lover on this forum, I suppose some of you even use vi ! vi rules !

------------------------------------------------------------------------------------------------------------------------------

After reading about a poor wretch who had become addicted to vi, I was inspired to compose the following ditty, sung to the tune of "Addicted To Love" by Robert Palmer.

As you sing this, it may help the effect to imagine a dozen women, all of whom resemble Bill Joy, dressed in black and dancing sinuously.

Addicted To Vi (with apologies to Robert Palmer)

You press the keys with no effect,
Your mode is not correct.
The screen blurs, your fingers shake;
You forgot to press escape.
Can't insert, can't delete,
Cursor keys won't repeat.
You try to quit, but can't leave,
An extra "bang" is all you need.

You think it's neat to type an "a" or an "i"-- Oh yeah? You won't look at emacs, no you'd just rather die You know you're going to have to face it; You're addicted to vi!

You edit files one at a time; That doesn't seem too out of line? You don't think of keys to bind-- A meta key would blow your mind. H, J, K, L? You're not annoyed? Expressions must be a Joy! Just press "f," or is it "t"? Maybe "n," or just "g"?

Oh--You think it's neat to type an "a" or an "i"-- Oh yeah? You won't look at emacs, no you'd just rather die You know you're going to have to face it; You're addicted to vi!

Might as well face it, You're addicted to vi!

You press the keys without effect, Your life is now a wreck. What a waste! Such a shame! And all you have is vi to blame.

Oh--You think it's neat to type an "a" or an "i"-- Oh yeah? You won't look at emacs, no you'd just rather die You know you're going to have to face it; You're addicted to vi!

Might as well face it, You're addicted to vi!
