At the very beginning of high school, I developed my own color-coded system of note-taking, using the three colored pens that were available to me at the time: Red for the core notes ('Rules' of thumb and explanations), Blue for Other Important Information™, and Green for definitions. These were the notes that would form the basis for this website. Full explanations can be read below.
Color Coding System.
# Rules
All numbered notes (which I call Rules) are red, and include examples and the basis for understanding a topic. The Rule numberings are sequential within each parent category: For example, Algebra II ends with Rule 77, while Precalculus begins with Rule 78, continuing through Single-Variable Calculus and Multivariable Calculus and all of mathematics.
Each Parent Category has a designated prefix abbreviation for the Rule Numberings: Physics has rules prefixed with "P. Rule", while Astronomy has "A. Rule". Mathematics, being the original Rules created under my system, has no such abbreviation.
# Other Important Information
"Other Important Information™", such as large-scale drawings that are better visualized than explained, were written in blue. Examples of what this entails can be seen here and here.
I use ascii line drawings sparingly - If I can convey information or a graph using an image online, I will do so.
# Definitions
Definitions are written in green. Much of the time, definitions for a concept will be placed directly prior to the Rules and Other Imp. explanations for it, so that the terms used in those explanations can be referred to without any confusion.
# WoO: Unnumbered Rules
Notes that begin with WoO "X". Y: [descriptor]. instead of the regular rule format are indeed rules, just those created after the fact, thus unnumbered.
In my work to make this website an all-inclusive library of knowledge, I have added this unique note-type for new additions to old sections. Since adding new rules would require moving all following rules up a number (an extremely tedious process), I have created WoO Rules, which are denoted only by their placement in relation to the Rules, Other Imp.'s, and Definitions before them (representing 'X' in the given formula). Example.
WoO is the only note-type that does not appear in my paper notes, as it is intended to be a digital supplement to the core material included in said notes. The WoO notes are, much of the time, created long after I originally took the course the notes pertain to, and thus have a more reflective view of the material than that of an individual who is learning it for the first time.
In order to make this website more encyclopedic, accessible, and organized, all WoO notes created during a particular year will become fully-fledged rules, or other types of notes, upon the creation of a new site edition, which I intend to do on a yearly basis once certain requirements are met - see January 18 2025 on the Change Log for more information on how this will occur.
Whether WoO notes are of a "higher quality" than the other notes is up for debate. Either way, I intend to undergo full studies of my existing notes over time to make elaborations and general improvements, making the Human Knowledge project into a more accurate and fully-fledged curated library of scientific and mathematical knowledge. This would, inevitably, lead to the creation of more WoO rules.
The name "WoO" is in reference to the compositional cataloging system used for composers like Beethoven and Brahms, literally meaning "Without Opus Number" in German.
