I set my colleages a challenge: write porn using only prime words.

"WIDEST WOMB WOMAN WATCHED PET PERVERT WHIP BLINDFOLDED YIDDISH BITCH"

"BAREBACKED BARD RUTTED BLINDFOLDED BITCH"

"BAREBACKED BARD PULVERIZED TRUCKMAN RUTTED TORRID"

"YARDMAN WHIP UNUSED WHELP, TROLLOP SUSPECTED SILKEN RUNT. PUTOUT, PARTED, LAIN. EVALUATED FETISH,EXPENDED. DISINTEREST."

I'm a little confused...why did he use base 36 instead of base 26? Aren't there only 26 letters we need to convert to numbers?
[+] nrr|16 years ago|reply
Consider hex and base 64. Base 16 takes the first six letters from the alphabet to augment the number of available letters for representing a particular value.

I guess using base 26 would make sense from a strictly alphabetic standpoint, but we've conventionally included the numbers 0-9 as part of the available letters for representation.

[+] zzkt|16 years ago|reply
by convention in base 36, numbers can be represented by [0-9] and [a-z]. 1(36)=1(10) a(36)=10(10) and z(36)=36(10).

I guess they think words somehow include numbers

Interesting. Could be fun to combine this with distributions on word length, etc... and compare the number of primes we see to the expected number of primes (using the prime number theorem).

Would be funny if we had a tendency towards prime words :)

Zen, zen, zen, zen, zen, zen, zen, zen, zen, zen, zen, zen, zen, zen, zen!

It seems fitting that 'zen' is prime.
[+] Hexstream|16 years ago|reply
And yet I doubt you'd have noticed that zen wasn't prime if it hadn't been.

Since this is a clearly meaningless list, it doesn't really need to be sorted alphabetically. I think it would have been more fitting to sort the list numerically.
[+] yan|16 years ago|reply
Won't numerically and alphabetically in this case be almost identical?
[+] graywh|16 years ago|reply
Then you'd just sort by length, too.

My personal favourite:

PRIMETEST

But the list is surprisingly long, so not that surpring that something concerning primes would be in there.

[+] yuan|16 years ago|reply
More interesting is what isn't there: so prime is not prime.
[+] nrr|16 years ago|reply
FERMAT is also one. :)

One-third of the prime words are past participles

  [~/misc]$ cat primeWords.txt | tr -cs "[:alpha:]" "\n" | uniq | wc

      2560    2560   21156

  [~/misc]$ cat primeWords.txt | tr -cs "[:alpha:]" "\n" | uniq | grep "ED$" | wc

       843     843    7594

One of the words is halloween. How fitting.
[+] imd|16 years ago|reply
I wonder if anyone will use this set of words for constrained writing.

Restriction? Henceforth, demonstration. You'd thought, "what person couldn't workup contrived composition?"
[+] mkelly|16 years ago|reply
I already thought "zenith" was a fun word, and this just makes me like it even more. Yay!

Sigh, I thought it would be about PDP-10, the coolest assembler I've ever seen.

It's a shame that neither TECO nor DDT are prime. :(
