Mathematical tools for thinking physicists]. Public Lecture at the 9th Annual Spring Meeting of the North Carolina Section of the American Association of Physics Teachers (NCS-AAPT) at Davidson College (October 29-30, 2004). So Hestenes is still active. Here is a link to the Programme.

The following is the text of the abstract, copied here for convenience:

Mathematics is essential for understanding physics, so how should that play out in the high school math/science curriculum? “Conceptual physics” courses ignore the problem. Mathematics teachers are oblivious to the problem. Physics teachers, at least, can understand the problem, though curriculum reform is fraught with difficulty.

We answer two questions: (1) what mathematics is most essential for general scientific literacy? (2) What mathematics is optimal for the math/physics curriculum? The answer to the second question is a pea(->e)k into the future –– an introduction to a new mathematical language called Geometric Algebra that integrates algebra, geometry, and trigonometry into a coherent system that simplifies and enhances applications to physics.

numbering of references

The method of used for numbering the references here is regrettable. If references are numbered by hand rather than by the software, and someone wants to add another one between 8 and 9, then all of the listed references after number 8 need to get renumbered by hand, and the places where they are cited in the article need to get changed! We have software that takes care of that. But it wasn't used here. Michael Hardy (talk) 04:21, 31 March 2012 (UTC)[reply]

Indeed. And there does not seem to be a particular reason why. Or am I missing something? --Chris Howard (talk) 11:47, 31 March 2012 (UTC)[reply]

I saw someone started the numbering cleanup but did not get around to completing it, so I completed that part of the work now. The reference numbering should be OK. --Chris Howard (talk) 11:30, 14 April 2012 (UTC)[reply]

That was me. I didn't carry on after [19] since there may have been a discrepancy between "[20]" in the list meaning "[19]" in the article or whatever, and didn't want to misplace any references (and had better things to do then anyway). I left a firm (maybe harsh...) note on that user's (Xtr rossi) talk page. Thanks anyway for your tremendous efforts though. F = q(E+v×B) ⇄ ∑_ic_i 12:08, 14 April 2012 (UTC)[reply]

Giant picture

While the diagram is nice, it isn't really informative about David Hestenes, it is informative about geometric calculus. I'm going to move it over to that article. Rschwieb (talk) 18:32, 11 April 2012 (UTC)[reply]

Proper names

I have re-worked much of the article yet remain doubtful about the use of proper names in this case, meaning that many of the words are in capital letters. Example: should the article refer to "Geometric Algebra" (capital letters) or "geometric algebra"? Same story for conformal geometric algebra, etc. It should at least be consistent within the article, better yet consistent with other Wikipedia articles. That would mean small letters—however, there may be a point to writing at least those approaches that Hestenes himself developed in capital letters (as proper names) within this article. The current situation is unsatisfactory. Any opinions? --Chris Howard (talk) 21:40, 14 April 2012 (UTC)[reply]

I'd like to think we can safely reduce "geometric algebra" to all lowercase, but the things like "Modeling Instruction" are a different story. A short time ago, terms like this were introduced in all caps, and then referred to as proper nouns. The all caps approach is certainly not in standard WP style, so that really shouldn't come back. Rschwieb (talk) 00:00, 15 April 2012 (UTC)[reply]

Good. I've reduced the scientific concepts to lower case now, adding acronyms where it could be helpful to indicate a distinct theory, e.g. "spacetime algebra (STA)". Concepts to be spelled in capitals for other reasons but not having their own Wikipedia article are now in italics for better distinction, e.g. "Modeling Instruction". --Chris Howard (talk) 07:57, 15 April 2012 (UTC)[reply]

Pending Science Invents Ponzi Scheme litigation

Another editor removed a section I added concerning the ongoing Science Invents litigation which Dr. Hestenes was involved in claiming it was a BLP issue. I note that in Donald Trump's articles there are lots of litigations he is involved in mentioned in the articles. What is the threshold for inclusion of such content in a biography? This litigation is being covered by Bloomberg Law and other press groups and is notable (and somewhat interesting) based on Dr. Hestenes endorsement of a phony anti-gravity device used to bamboozle over 25 million dollars from investors in some sort of ponzi scheme. I do agree that any such content be neutral but interestingly the other individuals involved on the scheme, such as Joe Firmage, are notable in their own right. I apologize in advance but why is it ok to mention pending litigations for Donald Trump and other biographies and not this one. Seems like a whitewashing to cherry pick who can or cannot have such content mentioned in a bio. Can someone give me some guidance here. Thanks. 24.21.161.89 (talk) 03:38, 24 October 2023 (UTC)[reply]

Since no one has responded to my question, I will wait a few more days then reinstate the edits. Calling public information reported by the news media does not meet the threshold of a BLP issue if it's factual and neutrally presented. 24.21.161.89 (talk) 00:36, 22 November 2023 (UTC)[reply]

I'm guessing that the issue the reverter had with your addition was that the first couple sentences seemed to imply that Hestenes was guilty. @I am One of Many, can you clarify? Thriftycat ^{Talk • Contribs} 01:00, 22 November 2023 (UTC)[reply]

Good point. I would agree that my first attempt was not entirely neutral. I will work on a version of the text and post it here for discussion. 24.21.161.89 (talk) 01:06, 22 November 2023 (UTC)[reply]

Science Invents, LLC propulsion project ponzi scheme

On August 30, 2023, Hestenes was named in a United States District Court case in Utah filed by several Venture Capitalists claiming he endorsed and participated in a Ponzi scheme related to a discredited anti-gravity propulsion technology that was being marketed by Science Invents, LLC in Salt Lake City, Utah, a company owned by Joe Firmage, the former founder of USWeb. He was alleged to have taken over $100,000 in kickbacks from Firmage and others principals involved in the scheme and for recruiting investors into this scheme. The suit alleges Firmage and others falsely claimed the propulsion technology had been endorsed by the Department of Defense and was funded by them, and also claimed Hestenes had endorsed the validity of the science underlying the technology, a claim which Hestenes has adamantly denied. In total, the Ponzi scheme allegedly defrauded investors of $25,000,000 over a 10 year period. The case is currently pending.^[1]^[2]^[3]
