Math Crankery with John Gabriel – “Cauchy’s Kludge”

(Previous post on John Gabriel: Calculus 102 (Cauchy Sequences and the Real Numbers)) Alright, now that we’ve tackled the basic definitions and theorems regarding calculus, we can start looking at Gabriel’s first video on calculus. 2. Cauchy’s Kludge Before we start, let’s play a little game. The above image is a screenshot of Gabriel’s video,…

Math Crankery with John Gabriel – Calculus 102 (Cauchy Sequences and the Real Numbers)

(Previous post on John Gabriel: Calculus 101 (Convergence and Derivatives)) Okay, now that we know what sequences are and what it means for a sequence to converge to some limit, we can finally start talking about real numbers: Irrational Numbers and Cauchy Sequences Basically the whole point of real numbers is to make the rational…

Math Crankery with John Gabriel – Calculus 101 (Convergence and Derivatives)

(Previous post on John Gabriel: The Dunning-Krüger Effect in a Nutshell) Few people can ever begin to match my intelligence and depth of insight. I am not arrogant or deluded.John Gabriel Yeah. That’s an actual quote. I’ve been made aware of Gabriel’s LinkedIn page, where he wrote hilarious posts about his new calculus and his…

Math Crankery with John Gabriel – The Dunning-Krüger Effect in a Nutshell

So, this crank John Gabriel exploded on the Mathmatical Mathematics Memes page on facebook recently, and he’s hilarious. Now, there’s cranks in every area of science of course; most notably in physics (quantum woo), biology (creationists), geology (creationists again), history (creationists again, holocaust-deniers), philosophy (theologians 😉) and of course medicine (alternative medicine, faith healing…), but…
