Look up the concept of intensional vs extensional equality. If law of identity reduces to P(x) iff P(x), then you are talking about intensional equality. Now consider two different definitions of pi:
>The limit of area of regular n-gons with apothem length 1 as n goes to infinity
>Liebniz formula: 1-1/3+1/5-1/7+...
We can write them both as definitions of pi, and thus, they can be considered extensionally equal in some world, but it is clear that not every predicate about one is true about the other:
>They convergence at different rates
>One implies the existence of some geometry
>Etc.
There you have it. We're doing no more than making a rule about how '=' can be used in the symbol game.

The material is interesting enough to deserve it's own thread, and /sqt/ can't handle anything past undergrad anyway. And why should we care? It's not like we volunteered to clean up /sci/ for free.

Just about! Southern Elephant Seals, specifically

It depends! Short-finned Pilot Whales have two subspecies, the Shiho and the Naisa. The Shiho is larger, being around 5-7m, while the Naisa SFPW are 4-5m. Long-finned Pilot Whales are 5-7m and ~3,000kg. :]

Quite the opposite. Think about it: if we were discussing, say, chemistry, would you keep asking "what is nitrogen?". Of course not, nitrogen is a well-defined concept and the nuances like the various isotopes are well known to anyone with even a slightly more than cursory interest.

Just as chemistry is the study of chemicals and their behavior, mathematics is the study of amounts and their behavior.

What's the most you can divide 1 by?

There's a big difference between the need for definitions and something I've noticed some people on the internet do, where they insist that you can't do mathematics without more and more and more and more specific definitions. Even objecting to 1+1=2 with that sort of reasoning.

But that's a loser's game. We can prove that cycle never stops. Eventually we have to agree "OK I understand what you're talking about" since a definition in an axiomatic system like this can never _truly_ be complete.

So if you have something you would like to see specifically clarified, we can do that. But if you say "natural numbers are an (equivalence class of) initial object in a category. rationals are an equivalence class of pairs of integers wrt a specific equivalence relation. reals are isomorphic to Dedekind cuts of rationals. surreal numbers are a kind of generalization of Dedekind cuts, now keep going with this until you get to the end" then you don't understand what you're asking since there is no end to that process of more and more and more rigorous definitions.

For sure! That's one big reason this is so important. It has extremely substantial impacts on how we view our world

depends how good of a general you are
