While many laypeople would consider most physicists to be well-versed in mathematics, we mathematicians generally would only consider a mathematician to be someone who publishes work on (usually) abstract mathmatics. A paper on physics, or chemistry, or, hell, island biogeography may contain a substantial amount of math.
But in this context it is being used as a tool to model the real world; mathematicians study math for its own sake.
If the current version comes from an even better source, can someone tell me what it is?
I e-mailed the person who made the changes, and he said he got his version from the Internet.
Nanobug (UTC) What year did he say his quotes???!!! Are we going to start keeping formulas in Wikiquote?
Nanobug , (UTC) It isn't a quote so should not be included.
Heck, the math in his papers wasn't even much more advanced than linear algebra, PDEs and tensor algebra, all things that I studied as an undergrad, and none of them new mathematically -- he relied heavily on Reimannian geometry and Differential topology concepts, none of them new when his paper was published, and certainly none authored by him.
As you probably are neither a physicist nor a mathematician, let me let you know: there is a certain about of (friendly) rivalry between the two disciplines, and mathematicians and physicists both often resent being misappropriated.
Mathematicians with a predominant interest in the mathematics of physics are generally called "mathematical physicists".
Einstein, as much as we all love him, was not either of these things.
