13 Math Jokes That Every Mathematician Finds Absolutely Hilarious - Business Insider
13 Math Jokes That Every Mathematician Finds Absolutely Hilarious - Business Insider:
http://www.businessinsider.com/13-math-jokes-that-every-mathematician-finds-absolutely-hilarious-2013-5
Back when the internet was young, the primary users were its builders, math and tech-oriented academics spread around the country.
Q: Why did the chicken cross the road?
Infinitely many mathematicians walk into a bar. The first says, "I'll have a beer." The second says, "I'll have half a beer." The third says, "I'll have a quarter of a beer." The barman pulls out just two beers. The mathematicians are all like, "That's all you're giving us? How drunk do you expect us to get on that?" The bartender says, "Come on guys. Know your limits."

Back when the internet was young, the primary users were its builders, math and tech-oriented academics spread around the country.
As a result, math jokes have an elemental role in the history of the internet.
From the earliest Usenet threads to the techiest subreddits, geeky math jokes — some implicit swipes at less-pure disciplines, other puns or plays on words of different concepts — have been a major part of the modern history of math.
What's more, these japes also have the effect of making those who didn't get the joke to look into what makes it funny, teaching people some of the more obscure concepts.
Here are just a few of the best ones. Where necessary, we'll do the unthinkable and the tacky and explain the joke.
JOKE #1
Three statisticians go out hunting together. After a while they spot a solitary rabbit. The first statistician takes aim and overshoots. The second aims and undershoots. The third shouts out "We got him!"
Source: chjilloutdamnit / Reddit
JOKE #2
Two random variables were talking in a bar. They thought they were being discrete but I heard their chatter continuously.
Source: armchairdetective / reddit
Explanation: When you roll a die, you either get a 1, 2, 3, 4, 5, or 6. Since there are a finite number of possibilities, the statistic involved is called a discrete random variable. When you select any real number from between 0 and 1, there are an infinite number of possible draws. The statistic involved is called a continuous random variable.
JOKE #3
There was a statistician that drowned crossing a river... It was 3 feet deep on average.
Source: anatiferous_outlaw / reddit
JOKE #4
Write the expression for the volume of a thick crust pizza with height "a" and radius "z".
Source: Reddit
Explanation: The formula for volume is π·(radius)2·(height). In this case, pi·z·z·a.
JOKE #5
A: "What is the integral of 1/cabin?"
B: "log cabin."
A: "Nope, houseboat--you forgot the C."
Source: Reddit
Explanation: We're treating "cabin" is a variable.
The integral of 1/x is loge(x).
However, since it's integration, you've got to add a constant.
So ∫(1/cabin) = loge(cabin) + c, or "a log cabin plus the sea."
JOKE #6
A: The answer is trivial and is left as an exercise for the reader.
Source: Reddit
Explanation:
This is a common refrain found in mathematics texts.
It is widely considered a cruel professor's malicious cop-out by particularly lazy students of mathematics.
JOKE #7
Q: How many mathematicians does it take to change a light bulb?
A: One: she gives it to three physicists, thus reducing it to a problem that has already been solved.
Source: MathOverflow
Explanation: Mathematicians try to reduce an unsolved problem to a form which has already been solved before. Once that's done it's considered complete, as the previously derived formula is taken as written.
There are many light bulb jokes about physicists. Finding several are left as an exercises to the reader.
JOKE #8
A physicist, a biologist, and a mathematician are sitting on a bench across from a house. They watch as two people go into the house, and then a little later, three people walk out.
The physicist says, "The initial measurement was incorrect."
The biologist says, "They must have reproduced."
And the mathematician says, "If exactly one person enters that house, it will be empty."
Source: Reddit
JOKE #9
The B in Benoît B. Mandelbrot stand for Benoît B. Mandelbrot.
Source: Reddit
Explanation: The Mandelbrot set is a fractal. As you zoom in on portions of the fractal, you ee a self replicating image. So the infinite paradox in the joke is a shoutout to the problem. Here's an example of what we're talking about with a gif of zooming in on a point of infinite complexity in the Mandelbrot set:
JOKE #10
Source: Reddit
Explanation: This is a reference to a converging infinite series.
The limit of this:
from n=0 to ∞ Σ (1/2n) = 1 + 1/2 + 1/4 + 1/8 + ... = 2
JOKE #11
An infinite number of mathematicians walk into a bar. The first one orders a beer. The second orders half a beer. The third orders a third of a beer. The bartender bellows, "Get the hell out of here, are you trying to ruin me?"
Source: Reddit
Explanation: This is another hilarious reference to an infinite series — the harmonic series — which is not convergent but instead diverges to infinity.
from n=1 to ∞ Σ (1/n) = 1 + 1/2 + 1/3 + 1/4 + ... = ∞
JOKE #12
When a statistician passes the airport security check, they discover a bomb in his bag. He explains. "Statistics shows that the probability of a bomb being on an airplane is 1/1000. However, the chance that there are two bombs at one plane is 1/1000000. So, I am much safer..."
Source: Andrej and Elena Cherkaev
Explanation: While this statistician is correct that the joint probability there are two bombs on a plane is 1/1,000,000, his bringing one on doesn't change the prior probability that there is still a 1/1,000 chance of his flight being the one with a random bomb.
JOKE #13
What do you get when you cross a mosquito with a mountain climber?
Nothing. You can't cross a vector and a scalar.
Source: Reddit
Explanation: A vector is a mathematical entity with both magnitude and direction in any number of dimensions. You can take the cross product of two vectors to form a new vector, similar to multiplication of real numbers.
A scalar is just a real number, a directionless magnitude in vector space. You cannot take a cross product of a scalar and a vector.
Hence, you can't cross a mosquito (disease vector) and a mountain climber (a scalar).
That is one terrible pun. I'm sorry.

Nova SBE quer um sistema capaz de acomodar estratégias diferenciadas
Portal de Comunicação da Universidade do Minho:
'via Blog this' The Honourable Schoolboy
| Para reformar o ensino superior sábado, 29-03-2014 Expresso |
| Nova SBE quer um sistema capaz de acomodar estratégias diferenciadas http://umonline.uminho.pt/uploads/clipping/NOT_117019/5315731253157312.pdf José Ferreira Machado O principal problema do Ensino Superior público (ES) não é o nível global de financiamento mas o conjunto de restrições e regras, quase soviéticas, que oneraram a sua gestão. A minha experiência à frente de uma faculdade pública sedimentou a convicção de que não existem soluções pronto a vestir para a generalidade das instituições. Com estas propostas gostaria de contribuir para a emergência de um sistema multifacetado, menos burocrático e capaz de acomodar estratégias diferenciadas. O estatuto do estudante internacional, aprovado em março, rompe com o atual sistema de acesso ao ES baseado num concurso nacional de acesso e no numerus clausus. A partir deste mês, as universidades públicas vão poder admitir alunos internacionais acima dos tetos fixados, selecionados por si e aos quais é cobrada uma propina refletindo o custo total da sua formação. Trata-se de um grande passo em frente mas que cria uma terrível iniquidade uma vez que os alunos nacionais, passíveis de ser admitidos nestas condições em escolas públicas, não podem usufruir da mesma possibilidade e vão continuar a ser enxotados para escolas de duvidosa qualidade. Proposta 1 — Alterar o modelo de financiamento e de admissão ao ES. De momento, cada escola pública recebe anualmente por aluno qualquer coisa como €1000 de propinas e mais cerca de €3000 do Orçamento do Estado (OE). Tendo estes valores como referência, defendo um modelo — envolvendo o mesmo custo para o aluno, o mesmo esforço para o contribuinte e idêntico respeito pela Constituição — que permite cobrar uma propina de €4000 a todos os alunos admitidos no ensino superior através do concurso nacional de acesso e no âmbito do numerus clausus, atribuindo-lhes o Estado uma bolsa de estudo de €3000. Paralelamente, defendo que as escolas públicas devem poder admitir alunos acima do numeras clausus desde que suportem por inteiro aquela propina, alargando a alunos nacionais o regime que, a partir de março, vigora para alunos internacionais. A próxima medida possui um alcance diferente e tem como objetivo assegurar às escolas condições de remunerar de forma competitiva os seus professores nacionais e internacionais. Falo de um instrumento que vai permitir combater o brain-drain das melhores instituições de ensino e de investigação. Proposta 2— Permitir a professores o opting-out do seu contrato em funções públicas. Este é substituído por um vínculo individual de trabalho de natureza privada. Ao fazê-lo, esses professores perdem a segurança de emprego (tenure) mas ganham a possibilidade de conquistar remunerações mais competitivas. O financiamento destes contratos deve resultar, exclusivamente, de receitas próprias (propinas, investigação ou prestação de serviços) e estes devem ser firmados através de veículos privados. Deste modo, evita-se que as remunerações sejam consideradas como despesa do Estado e que, em caso de incumprimento devido a quebra de receitas próprias, as instituições venham a repercutir essa despesa nos contribuintes. Existem muitos outros aspetos a merecer certamente atenção. Mas, a tentação de ‘sobre reformar’ encontra-se na génese dos espartilhos que asfixiam o ES. Defendo, indubitavelmente, o caminho oposto, permitindo que as energias se libertem, os modelos compitam e os resultados se comparem. |
