I’d be a cardinal number. An inaccesible one, just to be difficult. (ZFC simply isn’t good enough for me).

Anyone who gets that knows too much set theory. 🙂

Would that be weakly or strongly inaccessible?

Somehow I knew you were going to call me on that one. 🙂

I actually can’t remember the difference. I don’t really know that much about inaccessible cardinals - I’m still a relative novice to the world of set theory; I have a fairly good understanding of ZFC, but not all that much past it. I just do a fair bit of reading around so I pick up random pieces of information (like inaccesible cardinals) and just felt like being obscure.

You can’t beat my first post in this thread for obscurity. 😃

To be honest, I don’t know much about extensions to ZFC myself. I’ve just heard the words and decided to throw them back at you.

Actually… I think transcendentality is a decidable predicate. I have no real evidence to back this up, but it seems likely as the theory of roots of real valued polynomials is model theoretically ‘nice’.

So, while I can’t beat it for obscurity, I can be almost as obscure and be right on top of that. 🙂

Bluff, my friend, bluff.

IIRC ‘inaccessible’ is generally the same as ‘strongly inaccessible.’ Neither sort can be proved to exist in ZFC. But don’t quote me on that.

BTW I see cambridge in your location - does the set theory indicate that’s the original, rather than one of those Americna knock-offs? 😃

Maybe. But I had one before that, talking about [symbol]w[/symbol].

Anyway, I’m trying too hard to prove that I’m a geek, so I’m gonna stop now.

IIRC, in _Arrival_, the prisoner says “I am not a number, I am a person.” He does later say “I am not a number, I am free man!”, at least in the intro.

Shade: No, it doesn’t. I am in fact at the original British one, but the set theory is from my own reading - My course doesn’t cover it until next year (Which I’m most upset by). I’m not even sure how well we cover it then.

Ultrafilter: Chatain’s constant was the subject of an article in New Scientist, so it doesn’t get to count as that obscure. So there - I’m geekier than you! Nyah! 😛 Umm… Wait. Err. Hey, look over there! ::hides::

**Kitarak** : Snap; I’m a third year mathmo at Trinity. And you? I am doing logic, computaion and set theory this term, but unfortunately I’ve had a continual work/sdmb crisis for the last few weeks, so I won’t know how much ordinal/cardinal stuff it covers 'till I read up on the notes…

Prime, baby. Nothing but prime.
