@UCLAExtension I know a follow up course to the first half of Differential Topology is being offered for Winter 2022, but it doesn’t seem to be on the site yet to register. Can someone fix this?

I’ve downloaded my copy of The Dawn of Everything by David Graeber and David Wengrow for Dan Allosso’s forthcoming Obsidian-based book club. https://danallosso.substack.com/p/obsidian-book-club-the-dawn-of-everything

Curious to see how these tools can be communally used for collaborative note taking, knowledge creation, and discussion.

For the REAL @RoamResearch fans.

Ok zettelkasten fans. Unless someone can come up with an earlier source, the inventor of the zettelkasten method for excerpting and note taking is Konrad Gessner in 1548. (Again it’s not Niklas Luhmann!)

Text card that reads "1. When reading, everything of importance and whatever appears useful should be copied onto a good sheet of paper.  2. A new line should be used for every idea.  3.“ Finally, cut out everything you have copied with a pair of scissors; arrange the slips as you desire, first into larger clusters which can then be subdivided again as often as necessary.”  4. As soon as the desired order is produced, arranged, and sorted on tablesor in small boxes, it should be fixed or copied directly.  —Gessner, Konrad. Pandectarum sive Partitionum Universalium. 1548. Zurich: Christoph Froschauer. Fol. 19-20"

More details to come on this fun bit of history soon.
