If the leaders of Russia _and_ the US get together for a summit, the
mathematical operation of addition does not seem to convey what actually
happened.:)

I disagree. See especially the Kitcher book I mention above. I don't want
to recount all his arguments here, but that book should be required reading
for any interested in philosophy of math.

I don't make that claim. In another post, I've defined philosophy as
roughly general beliefs about life, the universe, and everything. That
said, I'm not making it into everything. (Everyone here should take the
time to tell us what they mean by philosophy in neutral terms before bashing
it.)

My point about Einstein, though, was not that he was doing philosophy at
every turn, just that a lot of his work was done not empirically but by the
hypothetico-deductive method: positing certain notions then finding out
where they led. After all, a purely empirical approach would have been just
to _stop_ with the Lorentz equation and no draw any further conclusions from
it. It worked, right? No need to speculate, if you're a pure empiricist...
But Einstein wasn't and the rest came from that.
