Odd primes

Several people are asked to prove that all odd integers greater than 2 are prime.

  • Tenured mathematician: 3 is prime, 5 is prime, 7 is prime, 9 is not prime. Ha! A counterexample.
  • Untenured mathematician: 3 is prime, 5 is prime, 7 is prime… so by induction, all subsequent odd integers are prime.
  • Statistician: Let’s verify this sone several randomly selected odd numbers, say, 23, 47, and 83.
  • Computer scientist: 3 is prime, 5 is prime, 7 is prime, segmentation fault?
  • Computer programmer: 3 is prime, 3 is prime, 3 is prime, 3 is prime…
  • Physicist: 3 is prime, 5 is prime, 7 is prime, 9 is an experiemntal error, 11 is prime…
  • Mechanical engineer: 3 is prime, 5 is prime, 7 is prime, 9 is approximately prime, 11 is prime…
  • Civil engineer: 3 is prime, 5 is prime, 7 is prime, 9 is prime…
  • Biologist: 3 is prime, 5 is prime, 7 is prime, 9 is… still awaiting results…
  • Psychologist: 3 is prime, 5 is prime, 7 is prime, 9 is prime but suppresses it, 11 is prime…
  • Economist: 2 is prime, 4 is prime, 6 is prime…
  • Politician: Shouldn’t the goal really be to create a greater society where all numbers are prime?
  • Sarah Palin: What’s a prime?

  2. The Computer Programmer should be more like: 1, 1, 1, 0, 1…

  3. I was laughing, right up until I saw the last one. You guys just can’t let it go can you? Pathetic.

  5. Leonhard Euler discovered that 2^32 + 1 = 4294967297 is divisible by 641 and so is not prime. http://www.gap-system.org/~history/HistTopics/Prime_numbers.html

  6. This is great! Another Mathematics site that’s also pretty good is the one I just came from http://mymathgenius.blogspot.com/ but this one is great for a laugh.

  10. Number 3: We can’t let it go that almost half of America wanted to elect, as vice president, a woman who can’t accurately describe what the 3 branches of our government do? No… hell no. We cannot let that go. 10:1 she actually doesn’t know what a prime number is.

  11. This was grand.

    To baslisks: never, ever read comments. You should know this.

    Also, and I quote: “]something insane supporting whatever Glenn Beck or one of the others said last night.]”

  12. As a computer programmer, I am offended by the lack of inventive computer programming humor. It could go like:

    - 3, 5, 7, 11, 13 etc are primes in this release. 9 is a known problem in this version of the theorem, but we’ll fix in in the next release. or
    - 3, 5, 7, 11, 13 are primes …Nobody really is going to expect us to handle the 9 case …:)

    besides that, yeah it was funny …even the Palin bit.

  13. ron: You’re right, Sarah is pathetic….which makes her ideal joke material.

  14. No, we can’t let it go… she was an idiot and “you people” stood behind her because of her political affiliation, not her positions.
