Jonathan Crabtree: a dangerous fraud

Monday, August 1st, 2022

Abstract: J. Crabtree is a fraud who knows neither math nor history, and would not be allowed to teach either subject to Australian school kids. I have called him a church mole, since he is a White man talking of “Bhartiya math” as a con trick to gain entry into Indian education. His object is to sow all kinds of confusion, while slyly defending key interests of false church history related to math. One such aspect of false church history is “Euclid” for EVIDENCE of whose existence I have offered large prizes. Crabtree does not have ANY evidence. Therefore, to save this church lie he pretends to “review” my Euclid book, 10 years after it was published! In typical church manner, he starts with a gross misrepresentation of my position, to launch an ad hominem attack (on my person) by telling some brazen lies which lies are proved false by the very subtitle of the book.

Declaration of personal interest. Crabtree  first wrote to PM Modi saying I should be given the Bharat Ratna, India’s highest award. When I didn’t rise to that bait, he now has many nasty things to say about me, as part of a filthy “review” of my book Euclid and Jesus.

Note. This blog is about Jonathon J. Crabtree https://orcid.org/0000-0003-2708-6900 an Australian based in Melbourne (NOT to be confused with Jonathon Crabtree https://orcid.org/0000-0002-7286-5690 an American based in Maryland).

Crabtree describes himself variously as a “private researcher”  and as a “K-8 math researcher” and “historian”, etc.

His educational qualifications? He attended B.Com in Economics at the University of Melbourne from 1980 to 1983. It is not clear whether he actually graduated even in that, since he says that he had an accident on his way to the University in 1983. His word that he is even a graduate is suspect: we need to see the (irrelevant) degree, since as shown below, he is a brazen liar.

In his ORCID entry, he has not indicated any employment record, since 1983 until now, which is a good 39 years of blank space. What was he doing that he is so ashamed to admit? Was he a priest? Certainly, he had NO academic employment ever, and certainly nothing to do with math or history, even as a school teacher.

But he says in his ORCID entry,”1983 to present | Elementary Mathematics Historian (Research) Employment” His “employment” apparently was directly with (the Christian) God: for he says (see above link) “I made it a promise to God that if I could walk again, that I would fix mathematics.  So that was 1983 and so since 1983 until now 37 years, I’ve been working on my personal goal of keeping my promise to God to fix mathematics.”

What was the outcome of working since 1983? His research? First article on “math” is in 2015, a good 32 years after his claimed his employment with his God began! What a fraud! If he did not cheat his God, by twiddling his thumbs for 32 years, he is cheating us by telling the above story to add 32 years of fake “experience”!

So, after 32 years, did he come up with something profound? No: only an alleged new reason why two negatives make a positive. This is in a magazine Vinculum published by the Mathematics Association of Victoria, which encourages first time writers: “Experienced and novice writers are encouraged to submit articles. Editors are able to support you in developing your ideas for an article, especially useful for first time writers.” Apart from another such article in the same magazine, he has some conference papers. That is the basis of his alleged “expertise” in math and history. In fact, like all frauds and cheats he claims to have some miraculous powers (like those of the silly Crusading “holy grail”) by calling himself “the Indiana Jones of math”.

The problem with this fraud: A White man saying “Bharatiya math” is an easy con-trick to get him entry with gullible Indians who do not check facts and believe he may be trying to do some good. He does not know any math, of course, but does not know any Sanskrit either.  What “Bharatiya math” will he do? He drops a few names, Aryabhata, Brahmagupta and so on, but seems thoroughly confused about negative numbers. (more…)
