While I do agree with you, I wouldn't be so quick to cast out numerology as a thing of importance. Hippies are pretty decent at sniffing things out, even if they explain them in totally insane ways.
EDIT: If you're opposed to this comment, I request that you explain your reasoning. Making the assumption that happiness is of any value, there's actually quite a bit to dig into here.
Numerology is factually not a branch of mathematics.
As for "hippies are pretty decent at sniffing things out", just because someone was correct about something in the past (despite a lack of evidence) does not make them correct today if they still lack evidence.
The burden of proof is on numerologists to show that they are correct, not on everyone else to disprove it.
Not saying it's correct. But given a world of infinite choices, sometimes it's helpful to look around at what's rising in importance on it's own. Even if there's no good reason.
The comment further up the chain (with the wikipedia links) was referencing the "importance" of 33 and 42 because they show up in quite a few fields -- assigning importance to certain numerical values is a kind of watered-down numerology (the fact that 42 was interesting in this problem doesn't necessarily mean that its "interesting-ness" transfers to the number itself).
(But I didn't bring it up, someone else did -- I was just responding to the argument that "there might be something to it".)
