Sorry to break this off, but this part involves something on which a

comment is warranted. First, math is a broad area in which all the

statements are "true in all possible worlds." This applies to arithmetic

and number theory, geometry, the calculus, complexity theory, and all the

rest of the special areas. This does not mean that all the theorems apply

equally to all situations. Both "one line parallel to a given straight

line can be drawn through a point on the plane not on the given line" and

"there are no parallel lines" cannot be true when applied within any

world simultaneously. They hold only in Euclidean and Riemannian

geometries. Something similar holds for ordinary and modular arithmetics.

Since within a specific mathematical calculus or system all statements or

theorems are proved "true," if a set of interpreted statements holds, one

may interpret other theorems in the expectation that they will also yield

physical truths. There is no guarantee that the process will yield an

unending series of truths. Changes may be required at some point. This is

seen most obviously in Newton's work, which may be viewed as an

interpreted Euclidean geometry. Everything worked for a couple of

centuries. But the next step was Einstein's interpreted Riemannian

geometry (Special Theory) which provided for Newton's results as a

limiting case. The math gets stickier with the General Theory.

As I see it, the problem from the empirical side is collecting enough

data on which a discipline can be based; on the theoretical, a system

that fits the observations, so that predictions can be made. This leads

to expansion and testing. I recall a report in the 50s that the

mathematics of something Einstein produced was so difficult that only

three persons living had the background to understand it. One of them had

taken the time to work through the math (18 months ?) and announced that

it was consistent. The report quoted him, "I'm only a mathematician. I

can't comment on the physics." I'm only a philosopher, so I don't know

what Einstein had presented, nor whether it was an advance or a dead end.

But I suspect that one reason the applicability of mathematics is lauded

is that the dead ends are not pursued and are soon forgotten. This type

of selectivity certainly functions in other areas of human recall. So I'm

not too surprised that our mathematics fit the world.
