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. this system by giving it desired goals and it will figure out how to do these goals so again he wants uh to put a hole in this flange so that he says make these guys uh parallel and mutually perpendicular and then he says i want these gu lines to be collinear

    1. Here’s a child node. It could be a comment on the thought -- an aside, a critique, whatever. It could be something which goes under the heading.

      Lone child nodes cry out for siblings.

      When I was in middle school a teacher told me only to put a sub-bullet point in an outline only if it wasn't an orphan (if you had one sub-point it should have at least one sibling, otherwise don't include it). This was miserable advice because it ended trains of thought which might otherwise grow into something.

      On the other hand it could be better framed that if you have only one child, you should brainstorm to come up with others.

    1. We added a mechanism for the variable motion of the sun and an epicyclic mechanism for calculating the “nodes” of the moon—the points at which the moon’s orbit cuts through the plane of the ecliptic, making an eclipse possible. Eclipses happen only when the sun is close to one of these nodes during a full or new moon. Medieval and renaissance astronomers called a double-ended pointer for the nodes of the moon a “dragon hand.” The epicyclic gearing for this dragon hand also exactly explained a prominent bearing on one of the spokes that had previously appeared to have no function.

    1. Extension developers may be interested in retrieving the citations within their notes. This information can be found within the citation table of the Org-roam database.
    2. It is common to use take reference notes for academic papers. To designate the node to be the canonical node for the academic paper, we can use its unique citation key:

      Useful tool for linking a bunch of disparate notes on a single paper.

    3. Org-roam attempts to load both the org-ref and org-cite package when indexing files, so no further setup from the user is required for citation support.
    4. You may assign multiple refs to a single node, for example when you want multiple papers in a series to share the same note, or an article has a citation key and a URL at the same time.
    5. org-roam-alias-remove
    6. To assign an alias to a node, add the “ROAM_ALIASES” property to the node:
    7. Nodes can also have multiple aliases. Aliases allow searching for nodes via an alternative name.

    1. Not all nodes are mining however. Most of the nodes on the Bitcoin network simply verify data

      Verification role nodes

    2. The computers connected to the blockchain network are known as nodes. Some nodes donate their processing power to solve a math problem associated with a new block. The Bitcoin community calls these people "miners,

    1. challenging for those using SNA.

      It is the blessing and the curse of SNA--it can do so much but it can also do too much. The analyst has to be clear in their question, defining what is a node and what is a link. It can get even trickier since nodes and links can also be reversed. Sometimes a node can be a link and a link can also be a node!

    2. networks the individual is a part of may have impacted that action.

      The focus of analysis is on the space between the individuals, i.e. the air, rather than on the character or traits of the individual. The traits and character can be used to understand what is going on in the relationship but SNA measures the links not the nodes.

    1. it shows the six degrees of separation.

      What SNA will help with is not only creating visuals of networks but providing metrics to be able to understand the different roles and positions each nodes plays in the network as well as comparing different network structures.
