Feynman diagram Updated +Created
I think they are a tool to calculate the probability of different types of particle decays and particle collision outcomes. TODO Minimal example of that.
And they can be derived from a more complete quantum electrodynamics formulation via perturbation theory.
At Richard Feynman Quantum Electrodynamics Lecture at University of Auckland (1979), an intuitive explanation of them in termes of sum of products of propagators is given.

Michael J. Saylor Updated +Created
  • twitter.com/saylor 2.6 M followers as of 2022. Because of Bitcoin? Or was he famous before that?
  • www.michael.com/ yes, he is Michael.com lol. When did he get the domain, and at what price? He's mildlly obsessed with domain names it seems: www.domainsherpa.com/saylor/. He also bought frank.com, mike.com. emma.com. This was between 1994 and 2000. He mentions that his email is saylor@strategy.com. strategy.com redirects to microstrategy.com as of 2022, so seems still valid.
    We actually got a backlink from tvt.phishlabs.com to this page in August 2022, a phising security provider, presumably for showing his email here. This reminds Ciro of the All GitHub Commit Emails event!
    A quick google for that address also leads to www.washingtonpost.com/wp-srv/liveonline/00/business/saylor0621.htm, a year 2000 profile page by the Washington Post, followed by a Q&A. In the Q&A, Michael himself gives his email in relation to Saylor Academy:
    Kensington, Maryland: What has happened to your vision of an internet university? I believe it is an important initiative and it doesn't require $100 million to get started. We at the Rockefeller Foundation would like to become involved. How can we do this?
    Michael Saylor: The internet university is alive and well. My goal is to initially roll out a cyber-libary of digital video that can be used by any for-profit or non-profit organization in order to accelerate the free education initiative. Eventually, people may just go direct to the web site.
    I think the entire thing will unfold over about 10 years.
    Send me an email if you would like to get involved. (saylor@strategy.com)
    so it was already beyond leaked. Ciro did hit that email address seeking funding for OurBigBook.com, but no reply unfortunately. Maybe you gotta be part of the Rockefeller family to get a reply from these people? Well, at least this led to Ciro learning about the Rockefeller Foundation.

Defining properties of elementary particles Updated +Created
A suggested at Physics from Symmetry by Jakob Schwichtenberg (2015) chapter 3.9 "Elementary particles", it appears that in the Standard Model, the behaviour of each particle can be uniquely defined by the following five numbers:
E.g. for the electron we have:
  • mass:
  • spin: 1/2
  • electric charge:
  • weak charge: -1/2
  • color charge: 0
Once you specify these properties, you could in theory just pluck them into the Standard Model Lagrangian and you could simulate what happens.
Setting new random values for those properties would also allow us to create new particles. It appears unknown why we only see the particles that we do, and why they have the values of properties they have.

A list of reviews of such systems is maintained at:
This is the class of existing software the perhaps comes the closest to OurBigBook, in particular systems such as:
While we believe that OurBigBook can hold its own against most of them as a personal knowledge base, there is one feature which we believe truly distinguishes OurBigBook from all others in a big way: trustless mind meld with the OurBigBook topic feature, which no other system seems to have.
Many such systems are also no publishing focused enough, and are more focused only in maintaining people's private knowledge bases. Some of them don't even have publishing at all, or its complicated. While publishing is optional in OurBigBook, it is a crucial feature and extremely well supported.

History of Wikipedia Updated +Created
A 2022 clone of phabricator.wikimedia.org/source/mediawiki.git gives first commits from 2003 by:
  • Lee Daniel Crocker: en.wikipedia.org/wiki/Lee_Daniel_Crocker
    He is best known for rewriting the software upon which Wikipedia runs, to address scalability problems.
    so that gives a good notion of the last major rewrite.
  • Brion Vibber
TODO when was wikipedia open sourced from Nupedia? The ealry days of Wikipedia are quite obscure due to its transition from Nupedia.
