Mathworld.com has about 5 definitions for "Langrangian", all of which
are like trying to find out what division is and being presented with 5
algorithms for doing it, when the student really was looking for:
"division is the ratio of two numbers".

I can tell that the Langragian is basic and general, which makes it
interesting. It seems to be some kind of abstract discrete structure
like a group or a lattice, and it's used kind of to mean "system".

Is it possible to describe the Langrangian such that even a
simpleminded fellow like myself can understand?

Thanx agin!
