    1. there is something in physics that cannot be copy. Quantum state, quantum state. Quantum state. There is the no cloning theorem, says do not copy. Not only that, but the maximum information that you can get if you make a measurement of the quantum state is one bit per quantum bit. Olivas theorem, Olivas theorem says that and we have or Labor's theorem ourselves. What I can say about what I feel is much, much less

    1. what you're referring to is the idea that people come together and through language culture and story they have narratives that then create their own realities like the 00:12:04 sociologist abely the sociologist wi Thomas said if people think people believe things to be real then they are real in their consequences
      • for: Thomas Theorem, The definition of the situation, William Isaac Thomas, Dorothy Swain Thomas, definition - Thomas Theorem, definition - definition of the situation, conflicting belief systems - Thomas theorem, learned something new - Thomas theorem

      • definition: Thomas Theorem

      • definition: definition of the situation
        • "The Thomas theorem is a theory of sociology which was formulated in 1928 by William Isaac Thomas and Dorothy Swaine Thomas:

      If men define situations as real, they are real in their consequences.[1]

      In other words, the interpretation of a situation causes the action. This interpretation is not objective. Actions are affected by subjective perceptions of situations. Whether there even is an objectively correct interpretation is not important for the purposes of helping guide individuals' behavior.|

    1. What is it with index cards ? .t3_17ck5la._2FCtq-QzlfuN-SwVMUZMM3 { --postTitle-VisitedLinkColor: #9b9b9b; --postTitleLink-VisitedLinkColor: #9b9b9b; --postBodyLink-VisitedLinkColor: #989898; } So I posted a while ago about my journey into the zettlekasten and I have to admit I still enjoy using this system for notes.I must say, I am an avid note taker for a long time. I write ideas, notes from books, novels, poems and so much more. I mainly used to use notebooks, struggle a while with note taking apps and now I mainly use two kind of things : index cards (A6) and an e-ink tablet (the supernote) for different purpose of course, the index cards for the zettelkasten and the e-ink tablet for organization and my work. To be honest I used to consider myself more a notebooks kind of person than an index cards one (and I am from France we don't use index cards but "fiche bristol" which are bigger than A6 notecards, closer to an A5 format)Still, there is something about index cards, I cannot tell what it is, but it feels something else to write on this, like my mind is at ease and I could write about ideas, life and so many stuff covering dozens of cards. I realize that after not touching my zettelkasten for a few week (lack of time) and coming back to it. It feels so much easier to write on notecards than on notebooks (or any other place) and I can't explain it.Anyone feeling the same thing ?

      Some of it may involve the difference in available space versus other forms of writing on larger pages of paper. Similarly, many find that there is less pressure to write something short on Twitter or similar social media platforms because there is less space in the user interface that your mind feels the need to fill up. One can become paralyzed by looking at the larger open space on a platform like WordPress with the need to feel like they should write more.

      With index cards you fill one up easily enough, and if there's more, you just grab another card and repeat.


      cross reference with Fermat's Last Theorem being easier to suggest in a margin than actually writing it out in full.

    1. "But there's a very famous theorem in topology called the Jordan curve theorem. You have a plane and on it a simple curve that doesn't intersect and closes—in other words, a loop. There's an inside and an outside to the loop." As Riehl draws this, it seems obvious enough, but here's the problem: No matter how much your intuition tells you that there must be an inside and an outside, it's very hard to prove mathematically that this holds true for any loop that can be drawn.

      How does one concretely define "inside" and "outside"? This definition is part of the missing space between the intuition and the mathematical proof.

    1. 8.3.1. I NTEGRAL C ONVERGENCE T HEOREM

      Integral of the limit of uniform converging function is the same as the integral of the lmit. Pay attention to conditions: 1. Closed and bounded interval \([a, b]\). 2. Sequence of CONTINUOUS functions. 3. Of course, converges uniformly.

    1. 4.7-3 Uniform Boundedness Theorem.

      A sequence of linear operator such that, pointwise the value of the linear operators are bounded is enough for the norm of the operator to be bounded for the limit of the sequence of linear operators.

    1. Theorem 9.4 (Complementary Slackness Optimality Conditions)

      Some flow is optimal, if and only if, there is some potential, where, the reduced costs for the potential satisfies the complementary slackness conditions for the duality of the linear program of the min cos flow problem.

    1. Bell’s theorem is aboutcorrelations (joint probabilities) of stochastic real variables and therefore doesnot apply to quantum theory, which neither describes stochastic motion nor usesreal-valued observables

      strong statement, what do people think about this? is it accepted by anyone or dismissed?

    1. Theorem 13

      For an accumulation point in a subset \(M\) of space \(X\), any epsilon balls with central isolation has ifninitely many points and there is a sequence in such epsilon ball such that it converges to the singularity but never really being on the singularity.

      Singularity: \(x_0\) as described in the proof.

    1. it became clear that Fermat's Last Theorem could be proven as a corollary of a limited form of the modularity theorem (unproven at the time and then known as the "Taniyama–Shimura–Weil conjecture"). The modularity theorem involved elliptic curves, which was also Wiles's own specialist area.[15][16]

      Elliptical curves are also use in Ed25519 which are purportedly more robust to side channel attacks. Could there been some useful insight from Wiles and the modularity theorem?
