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.

fafnir.phyast.pitt.edu/py3765/ Phys3765 Advanced Quantum Mechanics -- QFT-I Fall 2012 by E.S. Swanson mentions several milestone texts including:
- 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 issaylor@strategy.com.strategy.comredirects tomicrostrategy.comas 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: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.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)
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:
- Roam Research and its open source clone Foam
- Forester
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.

- Shared by others soo after:
- news.ycombinator.com/item?id=36279375#36280220 (212 points). Shame that this was published when we only had about 20 websites. As of writing we had 240. Might have been a greater hit then.

Reactions by others:
- 2023-06-19: www.reddit.com/r/numberstations/comments/14dexiu/after_numbers_stations_vanished/ (30 points) off topic on that sub, but thankfully was not deleted, interesting sub topic
- 2023-10-26: Google Analytics backlink from lms.fh-wedel.de/ path unknown. Some shitty German university: en.wikipedia.org/wiki/Fachhochschule_Wedel_University_of_Applied_Sciences LMS stands for Learning management system, apparently a Moodle instance. Maybe they have some Open educational resources, but all in German so pointless
- Second wave:
- 2023-12-01: news.ycombinator.com/item?id=38492304 (65 points). Second submission but pointing to OurBigBook.com rather than cirosantilli.com: ourbigbook.com/cirosantilli/cia-2010-covert-communication-websites We take those. Reached only 65 points as of January 2024.
- 2023-12-02: buttondown.email/grugq/archive/december-2-2023/. "grugq" is the handle of a zero day dealer whose received some scrutiny in 2012 after a Forbes protile was written about him: archive.ph/7mUG5. He comments:presumably referring to DNS Census 2013.
I don’t think anyone anticipated that databases leaked by hackers would enable OSINT researchers to conduct counterintelligence investigations that rival the state security services.

Basic analogue phones connected to the public exchange use two wires mainly arranged as a twisted pair to reduce noise. The voice signal is differential (the voltage in one wire equal and opposite to the other) biased above ground by 48V. Using a twisted pair reduces induced noise because the noise signal will induce an equal voltage in each wire and because the signal is transmitted as the difference the effect of the induced noise will be dramatically reduced.
