And if we're being loose with the word, and accepting that there's an enormous, and unmeasurable, level of doubt in such statements, then it's not uncommon to come up with paradoxical conclusions.

Let's look also at the another set with the same expected density, but even fewer are known - the $620 pseudoprimes. A conjecture about the density of those grossly overestimate the number that we've actually found - none. What are the chances of there being so few? The heuristics are simple, but the heuristics are naive. The data is simple, but the data is unassailably true.

It's not a big leap to say "one of the assumptions behind the heuristic must be wrong". Probably.

Which of course if different from a statement that the tally of such objects is finite - it only takes a small factor to make something infinite become pointlessly sparse.

Indeed. It was an "obiter dictum", now changed in

to the converse remark. Neither then nor now should Warren,

or others, seek to elevate it to a "conjecture" by Chris.

I have found Warren's contributions fruitful enough to set

aside his unfortunate tone in communicating them. Yet I am

still puzzled why he seems to need to be so combative in

what is, quite frankly, a place where he should not expect

the type of serious review that he might gain by taking the

trouble to write up his ideas in an appropriate form for

scrutiny by a more rigorous mathematical community.

In any case, thanks Warren, for the maths.

I simply "reported what wikipedia said, and asked about it, in

a concise way."

YOU, however, are being combative. Right now.

But your usual complaint-method omits actually explaining what the problem is.

In the rare cases where you do explain, such as here... I find it unjustified.

Here, for reference, was my entire damn post, in full, verbatim:

"What is the reasoning behind this conjecture?

(Wikipedia says Caldwell conjectured this.)"

end. full stop. I am satisfied with the answer I got to this enquiry (though I was expecting something deeper :)

Quite frankly, I find it puzzling why David seems to need constantly to be so

worried about others' tone, and/or why -- given that he does feel that need --

he feels the urge to be so mysterious about it when he does so.

Indeed, the very word "tone" is a very mysterious one. Anyhow, let me conjecture

that, similarly to the way some appreciate Beethoven's symphonies, while others who

are "tone deaf" (also called "amusic") hear nothing but somewhat annoying noise --

I do not perceive a vast symphony of something, that apparently is so obvious to David Broadhurst, that he cannot stop complaining about it, but at the same time it is so obvious to him that he sees no reason to actually explain instances.

Perhaps Broadhurst should take this conjecture into account before/during

his issuings of future complaints. I would assume the amusic are annoyed at being subjected to Beethoven, but even more annoyed about being harangued about it by Beethoven-lovers. - --- In primenumbers@yahoogroups.com,
