odd integers: liha cela števila
prime number: praštevilo
Several students were asked the following problem: "Prove that all odd integers higher than 2 are prime."
Mathematician: 3 is prime, 5 is prime, 7 is prime, and by induction, we have that all the odd integers are prime."
Statistician: 100% of the sample 5, 13, 37, 41 and 53 is prime, so all odd numbers must be prime.
Mechanical Statistician: 3 is prime, 5 is prime, 7 is prime, 9 is an outlier, 11 is prime, 13 is prime, .... all odd numbers are prime.
Measure nontheorist: there are exactly as many odd numbers as primes (Euclid, Cantor), and exactly one even prime (namely 2), so there must be exactly one odd nonprime (namely 1).
Physicist: 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 you're right."
Wouldn't a modern physicist employ something like renormalization?

17 is prime, 19 is prime, 21 is ... 21/3 is prime

Cosmologist: 3 is prime, yes it is true....
Engineer: 3 is prime, 5 is prime, 7 is prime, 9 is ..., 9 is ..., well if you approximate, 9 is prime, 11 is prime, 13 is prime... Well, it does seem right."
Engineer: 3 is prime, 5 is prime, 7 is prime, 9 is not working, fetch toolbox.
Engineer: 3 is prime, 5 is prime, 7 is prime, 9 is prime, 11 is prime... [Continue until told to go home by others]
Professor: 3 is prime, 5 is prime, 7 is prime, and the rest are left as an exercise for the student.
Computer scientist: I've just whipped up a program to REALLY go and prove it..." He goes over to his terminal and runs his program. Reading the output on the screen he says, "1 is prime, 1 is prime, 1 is prime, 1 is prime...."

The computer programmer method is:
"3 is prime, 5 is prime, 7 is prime, 9 is prime, 9 is prime, 9 is prime, 9 is ..."
Oops, let's try that again:
"3 is prime, 5 is prime, 7 is prime, 9 is ... 3 is prime, 5 is prime, 7 is prime, 9 is ... 3 is ..."

"3 is not prime, 5 is not prime, 7 is not prime, 9 is not prime..."
So much for the beta releases. Ship this:
"3 is prime, 5 is prime, 7 is prime, 9 is a feature, 11 is prime..."
and put on the cover "More prime numbers than anyone else in the industry!"

Logician:
Hypothesis: All odd numbers are prime
Proof:
1) If a proof exists, then the hypothesis must be true
2) The proof exists; you're reading it now.
From 1 and 2 follows that all odd numbers are prime.
