If a pulley system < P> has two ropes < RI > and < R2> over it, and the value (tension) associated with < RZ > is < nl > , then < nl > is also the value associated with rope < RZ > . P3. Rope hangs from or supports pulley. If there is a pulley system with ropes < RZ > and < R2> over it, and the pulley system hangs from a rope < R3 > , and c R1> and < R2 > have the values (tensions) < nl > and < n2 > associated with them, then the value (tension) associated with < R3 > is the sum of < nl > plus <n2>.

      Please explain to me how it is not evident to programmers that this is how we program.. we cannot hold more than seven items at a time. We cannot fracture. As Miller mentioned, 2 3 digit numbers are outside t capacity, but if you multiply them by paper w, if we free your memory, we can let the brain focus on the v

      If you assign the memory function to a diagram, you can let your brain concentrate on the manipulation function.

      Once we codify, we no longer have to keep the information in memory, for example : This hurts my brain

      There are five roads in Brown County. One runs from Abbeville to Brownsville by way of Clinton. One runs from Clinton to Derbyshire by way of Fremont. One runs from Fremont to Brownsville by way of Abbieville. That's all the roads in Brown County, and all the roads in and out of those towns.

      Which towns have roads connecting them directly to three other towns? Which towns have roads connecting them directly to only two other towns? How many towns must you pass through to get from Brownsville to Derbyshire?

      But if we diagram it to a map, all of this makes sense.

      "The learning of numbers and language must be subordinated ... Visual understanding is the essential and only valid means of teaching how to judge things correctly." ~ Johann Heinrich Pestalozzi

    1. Map of Content Vizualized (VMOC)

      a start of thinking on the space of converging written and visual thinking, but not as advanced as even Raymond Llull or indigenous ways of knowing which more naturally merge these modes of thinking.

      Western though is just missing so much... sigh

    1. It is difficult to see interdependencies This is especially true in the context of learning something complex, say economics. We can’t read about economics in a silo without understanding psychology, sociology and politics, at the very least. But we treat each subject as though they are independent of each other.

      Where are the tools for graphing inter-dependencies of areas of study? When entering a new area it would be interesting to have visual mappings of ideas and thoughts.

      If ideas in an area were chunked into atomic ideas, then perhaps either a Markov monkey or a similar actor could find the shortest learning path from a basic idea to more complex ideas.

      Example: what is the shortest distance from an understanding of linear algebra to learn and master Lie algebras?

      Link to Garden of Forking Paths

      Link to tools like Research Rabbit, Open Knowledge Maps and Connected Papers, but for ideas instead of papers, authors, and subject headings.


      It has long been useful for us to simplify our thought models for topics like economics to get rid of extraneous ideas to come to basic understandings within such a space. But over time, we need to branch out into related and even distant subjects like mathematics, psychology, engineering, sociology, anthropology, politics, physics, computer science, etc. to be able to delve deeper and come up with more complex and realistic models of thought.Our early ideas like the rational actor within economics are fine and lovely, but we now know from the overlap of psychology and sociology which have given birth to behavioral economics that those mythical rational actors are quaint and never truly existed. To some extent, to move forward as a culture and a society we need to rid ourselves of these quaint ideas to move on to more complex and sophisticated ones.

    1. Is anyone practicing sketchnotes like patterns in their notes?

      I've noticed that u/khimtan has a more visual stye of note taking with respect to their cards, but is anyone else doing this sort of visualization-based type of note taking in the vein of sketchnotes or r/sketchnoting? I've read books by Mike Rohde and Emily Mills and tinkered around in the space, but haven't actively added it to my practice tacitly. For those who do, do you have any suggestions/tips? I suspect that even simple drollery-esque images on cards would help with the memory/recall aspects. This may go even further for those with more visual-based modes of thinking and memory.

      For those interested in more, as well as some intro videos, here are some of my digital notes: https://hypothes.is/users/chrisaldrich?q=sketchnotes

    1. Another visual-mapping tool is Open Knowledge Maps, a service offered by a Vienna-based not-for-profit organization of the same name. It was founded in 2015 by Peter Kraker, a former scholarly-communication researcher at Graz University of Technology in Austria.

      Open Knowledge maps is a visual literature search tool that is based on keywords rather than on a paper's title, author, or DOI. The service was founded in 2015 by Peter Kraker, a former scholarly communication researcher at Graz University of Technology.

    1. Research demonstrates that gesture can enhance our memory by reinforcing thespoken word with visual and motor cues.

      Research shows that gesture can impact our memories by helping to associate speech with visual cues.

      References for this?

      Link this to the idea that our visual memories are much stronger than our verbal ones.

    1. What I'm interested in is doing this with visual artefacts as source material. What does visual pkm look like? Journaling, scrapbooking, collecting and the like. The most obvious tool is the sketchbook. How does a sketchbook work?

      It builds on many of these traditions, but there is a rather sizeable movement in the physical world as well as lots online of sketchnotes which might fit the bill for you Roy.

      The canonical book/textbook for the space seems to be Sketchnote Handbook, The: the illustrated guide to visual note taking by Mike Rohde.

      For a solid overview of the idea in about 30 minutes, I found this to be a useful video: https://www.youtube.com/watch?v=evLCAYlx4Kw

    1. Moving mental contents out of our heads and onto the space of a sketch pad or whiteboard allows us to inspect it with our senses, a cognitive bonus that the psychologist Daniel Reisberg calls “the detachment gain.”

      Moving ideas from our heads into the real world, whether written or potentially using other modalities, can provide a detachment gain, by which we're able to extend those ideas by drawing, sketching, or otherwise using them.

      How might we use the idea of detachment gain to better effect in our pedagogy? I've heard anecdotal evidence of the benefit of modality shifts in many spaces including creating sketchnotes.

      While some sketchnotes don't make sense to those who weren't present for the original talk, perhaps they're incredibly useful methods for those who are doing the modality shifts from hearing/seeing into writing/drawing.
