Root ⏎ This isthe highest level node, from which all other nodes descend. For instance, Physics, Mathematics, Chemistry, Biology, Linguistics, Philosophy are examples ofthe levelof generality of the first generation of descendants. For the second generation, the descendants, e.g., of Physics are Condensed Matter Physics, High-Energy Physics, etc. The number of descendants of any given node should be small, less than 10 or so. If more children appear, it means that some of them can be combined into a more generic node, with the details transferred into grand-children. For instance, an intermediate node Natural Sciences can be created under ROOT that combines general aspects of Physics, Chemistry,and Mathematics, with themselves becoming childrenof Natural Sciences. *Rewiring is easy!*⏎⏎The idea is to keep every node compact, limited to about a page of text. This way it can be easily perceived, as well as conveniently modified. Each node is a logical unit, self-contained for its level of generality/specialization. The hierarchy goes fromthe most general -- the ROOT --to more specialized, typicallythe forefront of current research. ⏎ **Feel free to editany node as well as add descendant nodes to any node!** ⏎ The goalis modest -- to build an ever-evolving tree of knowledge.
