Silly Job Title: Prime Hack.
In this video we tear down Electricity and Magnetism 3rd Edition written by Edward Purcell and David Morin and published in 2013.
Electricity and Magnetism is one of the books I am taking notes for as a part of my Learning the Art of Electronics project. These notes are a perk for people who support me on Patreon, so what are you waiting for!? :)
There is a website for the book maintained by the publisher, but regrettably there’s not much there, just some material available to instructors only: https://www.cambridge.org/Purcell-Morin
I mention two xkcd comic in the video, those are these: Farads and Nerd Sniping.
The “esu” is prounounced as “eee-ess-you” and is also known as the Statcoulomb.
I mention the Franck–Hertz experiment which happens to be something I wrote a Hackaday article about: A DIY Version Of The Franck-Hertz Experiment.
The first edition of Electricity and Magnetism was volume two in a five volume course: Berkeley Physics Course.
The books mentioned in Chapter 1 include The Flying Circus of Physics and How Things Work.
The websites mentioned in Chapter 1 are:
The Feynman (1977) reference is to The Feynman Lectures on Physics which is also available here: www.feynmanlectures.caltech.edu
The symbol: ∇ (“nabla”, an upside down Δ “delta”) is the vector differential operator and its key uses are:
- ∇f → gradient of scalar
- ∇·F → divergence of vector field
- ∇×F → curl of vector field
- ∇² → Laplacian
The Big Clive video that I mentioned was this one: How a stungun creates 20kV from a 9V battery.
I also mention the show’s wiki, the ITL Wiki, which is on the web over here: https://www.inthelabwithjayjay.com/wiki/
