culture hole

I understand from a glass of wine and a sausage this weekend that some of you not familiar with the theorem of the sieve.

is serious. but do not panic, it is found quickly on the internet ... I have not done everything, do not push, but that's your culture.

colander is called an instrument on which one can define three subsets: the interior, exterior and holes.

The interior is generally placed over the outside and consists mostly of noodles and water. The holes are not important. Indeed, a simple experiment can realize that we do not change significantly the qualities of the instrument by halving the number of holes, then reducing by half this half ... etc. ... etc. ... and the boundary until there is more holes at all. Hence: THEOREM

"The notion of colander is independent of the concept of holes and vice versa."

is called the First Order colanders colanders which pass the noodles NI NI water.
is called the Second Order colanders colanders that pass and noodles and water.
is called the Third Order colanders or strainers complex, sometimes sieves that let one or the other sometimes and sometimes not.

For a complex sieve lets water through and not the noodles, it is necessary and sufficient that the diameter of the holes is significantly smaller than the diameter of noodles. For a complex
colander lets noodles and not water, it is necessary and sufficient that the hole diameter is significantly smaller than the diameter of the water.

As for the First Order strainers which pass or noodles or water, there are two kinds: The strainers which pass or noodles or water or in one way or the other and those which pass or noodles or water in one direction only. These strainers there, they are called pans.
