Quantum Field Theory book by Mark Srednicki (2006) Updated +Created
Author affiliation: University of California, Santa Barbara.
Number of pages: 616!
Don't redistribute clause, and final version by Cambridge University Press, alas, so corrections will never be merged back: web.physics.ucsb.edu/~mark/qft.html. But at least he's collecing erratas for the published (and therefore draft) versions there.
The book is top-level organized in spin 0, spin half, and spin 1. Quite ominous, really.
The preface states that one of its pedagogical philosophies is to "Illustration of the basic concepts with the simplest examples.", so maybe there is hope after all.

I wonder where the spray painted sign went: twitter.com/profgalloway/status/1229952158667288576/photo/1. As mentioned at officechai.com/startups/amazon-first-office/ and elsewhere, Jeff did all he could to save money, e.g. he made the desks himself from pieces of wood. Mentioned e.g. at youtu.be/J2xGBlT0cqY?t=345 from Video 4. "Jeff Bezos presentation at MIT (2002)".

Bezos also told PDE stuff in interviews as early as 1999: archive.ph/a3zBK.

Sci-Inspi (YouTube channel) Updated +Created
The channel is also notable for the fact that the author makes his own music.

Wikipedia Updated +Created
  • you don't get any/sufficient recognition for your contributions. The closest they have to upvotes and reputation is the incredibly obscure "thank" feature which is only visible to the receiver itself: en.wikipedia.org/wiki/Help:Notifications/Thanks
  • deletionism is a tremendous problem on Wikipedia, for two main causes:
    • tutorial-like subjectivity
    • notability
    The stuff you wrote can be deleted anytime by some random admin/opposing editor, examples at: Section "Deletionism on Wikipedia".
    This also possibly leads to edit wars in the case of sub-page content (full page deletion is more clearly arbitrated).
  • Scope too limited, and politics defined. Everything has to sound encyclopedic and be notable enough. This basically excludes completely good tutorials.
  • Insane impossible to use markup language-base talk pages instead of issue trackers?! Ridiculous!!! That change alone could make Wikipedia so much more amazing. Wikipedia could become a Stack Exchange killer by doing that alone + some basic reputation system. Some work on that is being done at: www.mediawiki.org/wiki/Extension:DiscussionTools, already in Beta as of 2022.

Josephson current Updated +Created
Maximum current that can flow across a Josephson junction, as can be directly seen from the Josephson equations.
Is a fixed characteristic value of the physical construction of the junction.
Primer (YouTube channel) Updated +Created
This channel contains several 2D continuous simulations and explains AI techniques used.
The engine appears to be open source: github.com/Primer-Learning/PrimerTools (previously at: github.com/Helpsypoo/primer). Models are closed source however.
They have several interesting multiagent game ideas.
Claims Unity-based, so has the downside of relying on a non-FOSS engine.
Ciro became mildly jealous of this channel when he found out about it, because at 800k subscribers at the time, the creator is likely able to make a living off of it, something which Ciro thought impossible.
As of 2022 he was at 1.6M followers with only 17 videos! Of course, much of those videos is about the software and they require infinite development hours to video time ratios.
Much of this success hinges a large part on the amazing 3D game presentation.
Well done!
Created by Justin Helps. Awesome name.
To make things better, the generically named channel is also the title of one of the best films of al time: Primer (2004).
