SEMI-RETIRED


This user is no longer active at Conservapedia. God Bless.

But I do want to help clean up some incomplete work that I did for the MV Calculus course.

In a recent email to Andy, leading to the reinstatement of my account, I said, in part:

Although I have dropped out of the multivariable calculus project, I need to give Jacob a heads-up about the notation I used in my part of the lectures. Mostly in lecture 3.2, as I recall. I used somewhat unorthodox definitions of generalized coordinate systems -- "natural" coordinates rather than "orthonormal coordinates + Lamé coefficients". The latter are more common, but natural coordinates are, in my opinion, actually simpler and, well, more natural. Jacob probably prefers "orthonormal + Lamé". So he needs to decide: keep it my way, or change it to his way. The change would mostly involve changing my formulas (cross product, etc.) to the ones that are common in physics textbooks. ("Natural" coordinates, on the other hand, are common in tensor calculus textbooks.)

I also disagree with what he has written about limits, and want to discuss that.

....

I want the discussion to be on some talk page on Conservapedia, where any interested party can join in.

....

The block reason was, in any case, "Retired under voluntary circumstances; Admin(s) will reactivate upon request". There was further discussion of my situation, between Jacob and Ed Poor, at the talk page for Cramer's rule, which I would like you [AS] to look at.

I really can't help if I have to do everything in secret email. And I do want the MV calc course to succeed. And I notice that it is really going to happen, and that there is a lot of interest in it.

So I would like you to please restore my account and user/talk pages.

Andy did so, sending me a nice reply. He even apologized for having taken so long (5 hours) to get to it! (You see, he had previously acted on a request in only 2 hours :-)

So I want to discuss my past contributions to the multivariable calculus course. There may be some problems with integrating my material with that of others (Specifically JacobB, of course), since my approach to vector components in curvilinear coordinates was somewhat unorthodox. See my talk page, at the bottom.

My Past Contributions

I have contributed to the following articles. Some contributions were minor, but most were major, and many of these articles were created by me. Some got moved from my "sandbox" pages into article space by other people.

Algebra, Joseph-Louis Lagrange, exponent of "r" in Newtonian gravity, Calc3.1/2/3/4/5, tensor, wave equation, e (mathematics), vector, vector space, vector field, conservative vector field, irrotational vector field, Maxwell's equations, Hodge star, exterior derivative, Cramer's rule, Riemann integral, Green's theorem, dense subset, limit (mathematics), boolean algebra, mathematical paradoxes, function, complex analytic function, continuity, countable, group, real number, rational number, complex number, Cauchy sequence, Dedekind cut, bijection, injection, surjection, ham sandwich theorem, two-pancacke theorem, divergence, curl, cross product, dot product, infinity, functor, continuous function, Bolzano-Weierstrass theorem, principle of induction, general relativity, real analysis, Pierre Simon Laplace, diagonalization.

My Future Plans

This section under construction. I may need to consult with some sysops on this. Fixing the Compass and straightedge article is an important item.
