    1. let me comment on your quantum physics i have only one objection please i think it's uh uh it's 01:01:21 what you said about the two uh sort of prototypical uh quantum puzzles which is schrodinger the double slit experiment uh it's uh it's perfect um my only objection is that in my book 01:01:34 i described of course i had a chapter about schrodinger cat but i don't use a situation in which the cat is dead or alive 01:01:46 i prefer a situation in which the cat is asleep or awake just because i don't like killing cats even in in in in mental experiments so after that 01:01:58 uh uh replacing a sleep cut with a dead cat i think uh i i i i completely agree and let me come to the the serious part of the answer um 01:02:10 what you mentioned as the passage from uh the third and the fourth um between among the the sort of the versions of 01:02:25 wooden philosophy it's it's exactly what i what i think is relevant for quantum mechanics for this for the following reason we read in quantum mechanics books 01:02:37 that um we should not think about the mechanical description of reality but the description reality with respect to the observer and there is always this notion in in books that there's observer or there are 01:02:50 paratus that measure so it's a uh but i am a scientist which view the world from the perspective of 01:03:02 modern science where one way of viewing the world is that uh there are uh you know uh billions and billions of galaxies each one with billions and billions of 01:03:14 of of of stars probably with planets all around and uh um from that perspective the observer in any quantum mechanical experiment is just one piece in the big story 01:03:28 so i have found the uh berkeley subjective idealism um uh profoundly unconvincing from the point 01:03:39 of view of a scientist uh because it there is an aspect of naturalism which uh it's a in which i i i grew up as a scientist 01:03:52 which refuses to say that to understand quantum mechanics we have to bring in our mind quantum mechanics is not something that has directly to do with our mind has not 01:04:05 something directly to do about any observer any apparatus because we use quantum mechanics for describing uh what happened inside the sun the the the reaction the nuclear reaction there or 01:04:18 galaxy formations so i think quantum mechanics in a way i think quantum mechanics is experiments about not about psychology not about our mind not about consciousness not 01:04:32 about anything like that it has to do about the world my question what we mean by real world that's fine because science repeatedly was forced to change its own ideas about the 01:04:46 real world so if uh if to make sense of quantum mechanics i have to think that the cat is awake or asleep only when a conscious observer our mind 01:05:00 interacts with this uh i say no that's not there are interpretations of quantum mechanics that go in that direction they require either am i correct to say the copenhagen 01:05:14 school does copenhagen school uh talk about the observer without saying who is what is observed but the compelling school which is the way most 01:05:27 textbooks are written uh describe any quantum mechanical situation in terms okay there is an observer making a measurement and we're talking about the outcome of the measurements 01:05:39 so yes it's uh it assumes an observer but it's very vague about what what an observer is some more sharp interpretation like cubism uh take this notion observer to be real 01:05:54 fundamental it's an agent somebody who makes who thinks about and can compute the future so it's a it's a that's that's a starting point for for doing uh for doing the rest i was 01:06:07 i've always been unhappy with that because things happen on the sun when there is nobody that is an observer in anything and i want to think to have a way of thinking in the world that things happen there 01:06:20 independently of me so to say is they might depend on one another but why should they depend on me and who am i or you know what observers should be a you know a white western scientist with 01:06:32 a phd i mean should we include women should we include people without phd should we include cats is the cat an observer should we fly i mean it's just not something i understand

      Carlo goes on to address the fundamental question which lay at the intersection of quantum mechanics and Buddhist philosophy: If a tree falls in the forest, does anybody hear? Carlo rejects Berkeley's idealism and states that even quantum mechanical laws are about the behavior of a system, independent of whether an observer is present. He begins to invoke his version of the Schrödinger cat paraodox to explain.

    1. I grew up in a small town called Surry on the coast of down-east Maine. At Christmas, most everyone in our town bought their trees at Jordan's Tree Farm. $5 per tree, cut at your own risk. Thinking back, it seems funny to me now, since after all, this is rural Maine, the pine tree state. And you'd think everyone could cut their own trees on their own land. And it's not like the trees at the Jordan farm were so special. Pretty much everyone called them Charlie Brown trees. People came because of Robert Jordan. They were loyal to him, and they figured he could use the money.

    1. A tree with ‘n’ vertices has ‘n-1’ edges.
    2. The edges of a tree are known as branches. Elements of trees are called their nodes. The nodes without child nodes are called leaf nodes.

    1. In computer science, a tree is a widely used abstract data type that simulates a hierarchical tree structure

      a tree (data structure) is the computer science analogue/dual to tree structure in mathematics

    1. Title: "goal the use case is trying to satisfy"[23]:101 Main Success Scenario: numbered list of steps[23]:101 Step: "a simple statement of the interaction between the actor and a system"[23]:101 Extensions: separately numbered lists, one per Extension[23]:101 Extension: "a condition that results in different interactions from .. the main success scenario". An extension from main step 3 is numbered 3a, etc.

      Not sure why I find this example so interesting.

      Probably because it is a human-readable outline that uses machine-readable (programming language source code) constructs, namely loops/iteration.

      The format in which this is written in, then, is itself a kind of (high-level, human-oriented) programming language.

      Example:

      • numbered list of steps [introduces/names the loop/iterator/enumeration being done]
        • Step: "a simple statement of the interaction between the actor and a system" [defines the inner part of the loop that gets "executed" once per iteration]

    1. With the advent of JavaScript modules (import and export), it's possible to build libraries that are tree-shakeable. This means that a user of your library can import just the bits they need, without burdening their users with all the code you're not using.
    2. If tree-shaking still fails, it's because Rollup thinks that there are side-effects somewhere in your code.
    3. Avoid transpilers like Babel and Bublé (and if you're using TypeScript, target a modern version of JavaScript)
    4. Don't create instances of things on initial evaluation — instantiate lazily, when the functions you export are called

    1. Provides state management for tree-like components. Handles building a collection of items from props, item expanded state, and manages multiple selection state.
    1. My first thought was that the house had caught fire, and I would arrive only to a scorched ruin and blackened bone, but as we got closer I could see that it was a single tree that was burning. A gnarled and ancient elm, that sat removed from the rest of the forest. A small crowd surrounded the spectacle. One man, who I took to be a groundskeeper, stood closer than the others, with a lit torch in his hand. On my instruction, the driver pulled closer, though the horses were nervous, and I asked the man why they were burning the tree, when the rain was coming down so heavily. Surely it could have waited for drier weather. The man simply shrugged. My German is… fine, though I have had little cause to use it of late, but his accent was thick, and all that I could get from him was a sense of… resignation, and the insistence that his master, who I took to be Albrecht, wanted the tree dead. I’m sure that he used that word, though. Not burned, not removed, or destroyed. Dead. I resolved to ask Albrecht about it when I saw him.

      Creepy tree! Maybe similar to the HTR tree?

    1. Tree of Life

      The 'Tree of Life' has been present throughout many cultures and religions across history. It has been known by many different names but the meaning is always a source of life or a creator. The ancient Egyptians, Christians, Myahs, and Assyrians all believed in this 'Tree of Life.'

    1. The neighbour‐joining tree was prepared with the R package {Ape} (Paradis, Claude, & Strimmer, 2004) and visualized using the R package {ggtree} (Yu, Smith, Zhu, Guan, & Lam, 2017).
    1. Let's say you import { Interface } from "api/interfaces", from source file /src/views/View.ts. Typescript would then look for the module in the following paths: /src/views/api/interfaces.ts /src/api/interfaces.ts /api/interfaces.ts

    1. mark the workers as permanent or transient, so that if they fail they get restarted

      restart defines when a terminated child process must be restarted.

      • A permanent child process is always restarted.
      • A temporary child process is never restarted (even when the supervisor's restart strategy is rest_for_one or one_for_all and a sibling's death causes the temporary process to be terminated).
      • A transient child process is restarted only if it terminates abnormally, that is, with another exit reason than normal, shutdown, or {shutdown,Term}. https://erlang.org/doc/man/supervisor.html

    1. Start the branching with 4 powers of 2: 20, 21, 22 and 23

      We branch with these powers because the prime factorization has \(2^3\). If it were instead \(2^5\), we would branch with \(2^0\), \(2^1\), \(2^2\), \(2^3\), \(2^4\), and \(2^5\), and we would have a branching factor of 6.

    3. arborescence

      First sighting of word arborescence. I thought they were just doing that for fun, as a play on "tree", but I guess it's a real graph theory concept (https://en.wikipedia.org/wiki/Arborescence_(graph_theory)).

    1. Vim does not only offer unlimited undo levels, later releases support an undo tree. It eventually gives the editor VCS-like features.

    1. In order to maintain this property, each node has a rank, which indidates the length of the path between the node and the right most leaf. For example,

      Rank - https://en.wikipedia.org/wiki/Leftist_tree#S-value

      Rank of a node, is the distance from that node to the nearest leaf in the subtree rooted at that node.

    1. Let's briefly look at the libraries, use cases, and factors that might help in deciding which is right for you. Here's a high-level decision tree: If you want fast and easy setup and integration, then component-playground may be the ticket! If you want a smaller bundle, SSR, and more flexibility, then react-live is for you! Here are the various factors at play:

    1. Saussure stresses that signs arc arbitrary and without inherent meaning

      Saussure is that guy with the tree picture.

      You know . . .

      . . . that one. I figure this image is more important to knowing who he is than a picture of his face.

    1. select proprietary or out-of-tree modules (ex. vitualbox, nvidia, fglrx, bcmwl, etc.)

      If anyone is wondering what other modules they refer to, or how to discover any on your own system, this StackExchange thread on how to identify out-of-tree modules might help.

    1. This article mentions beating the tree [http://www.whitedragon.org.uk/articles/wassail.htm]

      If there is some historical accuracy in that account, I wonder if it should be included in this section.
