Not surprising that they say the same about differential geometry: Lagrangian mechanics is written in differential geometry.

There is a certain slopiness in the way many physicists (not all) handle formulas.
That kind of slopiness is completely unforgiven in programming which punishes
every small error. What is truly amazing is that theoretical physics is much more agreeable lady so that one can
get quite far in such a fuzzy way. We all know how we do it – we correct things further on the way using symmetries,
limit cases, common sense etc. The formalism is usually so powerful, it works for you. But that’s because the people
who invented the formalism weren’t of this sloppy kind.

I would have loved to read that paper but unfortunately i can’t open .ps files.

This article reminds me Martin Wainwrigh said that the physicists are very smart but sometimes it is hard to understand their notation when I was discussing papers on survey propagation with him. I will try to read the book you recommend and see whether it can help me understand the variational principle in classical mechanics.
