If I had only one day left to live, I would live it in my statistics class: it would seem so much longer.

Proof E equal to one

Theorem: e=1Proof:2*e = f2^(2*pi*i)e^(2*pi*i) = f^(2*pi*i)e^(2*pi*i) = 1Therefore:2^(2*pi*i) = f^(2*pi*i)2=fThus:e=1

Risk of plane bombs

A mathematician and a non-mathematician are sitting in an airport hall waiting for their flight to go. The non has terrible flight panic.”Hey, don’t worry, it’s just every 10000th flight that crashes.””1:10000? So much? Then it surely will be mine!””Well, there is an easy way out. Simply take the next plane. It’s much more probable [...]

The fate of marriages

It is often cited that there are half as many divorces as marriages in the US, so one concludes that average marriages have a 50% chance of ending by divorce. While I was a graduate student, among my peers there were twice as many divorces as marriages, leading us to conclude that average marriages would [...]

There is no truth to the allegation that statisticians are mean. They are just your standard normal deviates.

Debate about the box

An engineer, a physicist, and a mathematician are trying to set up a fenced-in area for some sheep, but they have a limited amount of building material. The engineer gets up first and makes a square fence with the material, reasoning that it’s a pretty good working solution. “No no,” says the physicist, “there’s a [...]

Reducing travel risk

There was this statistics student who, when driving his car, would always accelerate hard before coming to any junction, whizz straight over it , then slow down again once he’d got over it. One day, he took a passenger, who was understandably unnerved by his driving style, and asked him why he went so fast [...]

Log negative one zero

Theorem: log(-1) = 0Proof:a. log[(-1)^2] = 2 * log(-1)On the other hand:b. log[(-1)^2] = log(1) = 0Combining a) and b) gives:2* log(-1) = 0Divide both sides by 2:log(-1) = 0

Crocodile is longer

Prove that the crocodile is longer than it is wide.Lemma 1. The crocodile is longer than it is green: Let’s look at the crocodile. It is long on the top and on the bottom, but it is green only on the top. Therefore, the crocodile is longer than it is green.Lemma 2. The crocodile is [...]
