John Baez says...

If you work out a manifestly coordinate-independent formula like

T^uv=(u+p)U^uU^v + g_uv p

using some signature, and then you whimsically decide to change your

conventions regarding the signature, the formula will still be true

without any changes.

Yes, but something that's interesting is that when we deal

with Clifford algebras, the algebra for (+---) spacetime is

not the same as the algebra for (-+++) spacetime. I don't

think that that difference would allow us to say that we are

*really* one signature instead of another, though.
