# Sieve of Eratosthenes sieve

 (+10) [vote for, against]

The perfect gift for the cook/mathematician.

Mmm.. selects only the primest of all numbers. http://en.wikipedia...eve_of_Eratosthenes

Annotation:

Like it, but it would take 4 shakes to let out the first grain of rice, then another 2 for the next one, and then another 2 for the next, and then you'd get one for the next 2 shakes...

Could be - I was imagining it to be a square sieve with 10,000 holes in a 100x100 grid, but with some of the holes (i.e. the primes) blocked, in a "Sieve of Eratosthenes" pattern.
 — hippo, Mar 31 2011

Well that would be a simpler way of doing it I suppose!

I have no idea what the Sieve of Eratosthenes is, but I hope the holes don't get blocked up as easily as they do on the one in my kitchen. Can you buy it in Steamer?

That spiral thing.

How big is it?

Global!

but if I only get primes, I won't be able to divide recipes if I want to make less
 — EdwinBakery, Mar 31 2011

 but if you filter out all the prime numeraled grains of rice, how do you keep track of all the grains? Isn't just a new pile of rice?

Does prime numbered food cook faster? Or maybe it tastes better?
 — EdwinBakery, Mar 31 2011

Both, according to marketing.

The PR folks at BUNGCO forsee trouble with "Eratosthenes". Many Americans spit a lot when saying it. They propose shortening it to "Erato" or "Eroto".

Ah! This explains a long-standing mystery. I was wondering why "Steve of Eratosthenes" was so famous.
 — MaxwellBuchanan, Mar 31 2011

I know Erato, but who's Steve.
 — pashute, Mar 31 2011

 /who's Steve/

Sieve, and i went out for t.
 — bungston, Mar 31 2011

ohhhhh, so THAT's why they call it "prime" rib
 — EdwinBakery, Apr 01 2011

(+) Still takes second place to the Collender of Cleomedes though.

Serve on a Bed of Procrustes.
 — MaxwellBuchanan, Apr 02 2011

 Just to be picky, the sieve of Eratosthenes is an algorithm for finding the primes, not the pattern of primes itself. A true SoEs ought to behave as [zen tom] first suggested.

Alternatively, with each shake a bit of metal could fall out into your cake mix, representing each composite as it is eliminated, and adding a fresh hole to the sieve.
