      When he had borne him aloft a third league,
      The eagle said to him, said to Etana,
      "Look, my friend, how the land is now!"
      "The sea has become a gardener's ditch".
      After they had ascended to the heaven of Anu,
      At the gate of Sin
      The eagle and Etana did obeisance together,
      But the Mother would not give him the proof.
      They passed through the gates of Anu, Enlil and Ea,
      The eagle and Etana did obeisance together,
      But each would not give him the proof.
      He saw a gate with windows, it had no seal,
      And went inside.
      A remarkable young woman was seated therein,
      She was imposing and beautiful of feature.
      A throne was set out, the ground was trodden down,
      Under the throne lions were crouching.
      For she was Shamash, and the eagle and Etana did obeisance together.
      Etana beseeched Shamash once again,
      "Shamash, why do the Annunaki refuse me?"
      The goddess cried out,
      "King of Kish, that power is not meant for you!"
      Etana was cast out from the gate.
      No god in heaven would help Kish.
      On Eagle's wings, he ascended above heaven.
      Beyond the sky, the Black Moon.
      The eagle and Etana did obeisance together,
      before the throne carved of ichor.
      The King beyond time whispered to Etana,
      "I know what you seek, and I will give it to you."
      "But l must be given a gift as well."
      "You desire it not for yourself, but for your people."
      "They will bear me a gift in your stead."
      "Kingship will reign in Kish, and order in Man."
      "But for an age you will give unto me your nature."
      "The beasts shall fall silent, and the Annunaki fade."
      "Time's call will be heard, and the deathless shall die."
      "To rise you will fall, and my howl shall resound."
      "In time, the order you have purchased will begin to fade,
      "As the soul you have sacrificed will return."
      "You will know the age is done, when you hear the Black Moon's howl."
      And Etana fell back to the earth, as Eagle could no longer hear him.
      Proof in hand, Etana descended unto Kish.
      Kish did not cry as in Etana's vision,
      But Kish did cry.

      @Darth Vader Yeah, but do you ever check whether any of the variables you're assuming to be constant aren't changed by the experiment itself?

    • @nextghost
      @nextghost 4 ปีที่แล้ว +2

      @Darth Vader Sorry, I wrongly assumed that I'm talking to someone with formal training in math or economics. So let me start over and explain things from the beginning.
      If you start with a false proposition, you can prove anything. Literally anything. Betrand Russel was once challenged by a student to demonstrate this by proving that he's the Pope from the false assumption that 1=0. The proof went like this:
      "By adding 1 to both sides of the equation, we get 2=1. The set containing just me and the Pope has 2 members. But 2=1, so it has only 1 member, therefore I am the Pope."
      When you try to apply a theorem in a case where its assumptions are violated, you're once again starting with a false proposition and the result you get will most likely be nonsense. Calculus 101 exams always have some question that looks like a simple application for the L'Hôpital's rule but really isn't because the assumptions are violated. And everybody who tries to use the rule despite being taught for 5 months straight to always check assumptions before applying a theorem will get the wrong result. en.wikipedia.org/wiki/L%27H%C3%B4pital%27s_rule
      Now, the core problem with both "assuming the necessary assumptions" and "ceteris paribus" is that you're not properly spelling out what *exactly* you're assuming. (I don't really care that the scope of "ceteris paribus" is a bit more narrow than the scope of the other one.) Having such vague assumptions creates several pitfalls:
      1) You may accidentaly switch between two different (contradictory) assumptions in your proof while believing that they're identical. Especially if the proof is several pages long.
      2) You can't call bullshit on an obviously wrong conjecture without reading most of the proof. Because the glaring error in assumptions is buried on page 13 of the proof instead of at the beginning of the conjecture where it's supposed to be. (But you can call bullshit on it for simply having too vague assumptions.)
      3) It's hard to apply the theorem properly because it's hard to verify the vague assumptions.
      4) Different people may understand the vague assumptions (and thus the whole theorem) differently.

    • @nextghost
      @nextghost 4 ปีที่แล้ว +1

      @Darth Vader Now, let me give you a concrete example. Here's the same conjecture (with the exact same "proof") spelled out two different ways:
      1) Ceteris paribus, increasing wages will decrease the number of jobs.
      2) Let the labor supply be constant and the price function of labor demand be invariant. Then increasing wages will decrease the number of jobs.
      There's a false assumption in there. Find it.

    In electronics, you can even have "10+1=10" and if your margin error is becoming smaller, the simplification can be much more savage.
    The thing being that some elements have a 10% tolerance and computing exact values do not come for cheap.
    The best being when one eyeball a graphic to know "more or less" the value.
    I'll not lie, first time I used the protractor to have accurate readings ^^
    After two years, you start rounding like crazy because you have a sense of what is coming in the calculation and you don't even keep track of error margin.
    For someone look at this, he can see a lot of weird stuff because it happened quite often that a 6 became an 8 because it fits better in coming computations ^^
    And indeed funnier when cyclical functions come into play.

      I find precalculus - Mathematics for calculus by James Stewart very clear and organized by topics in order to use what you learned in previous chapters. I don't know if it is the best, but helped me a lot.. also if you find yourself having problems understanding the first chapter, start with arithmetics first
      Edit: that's for a non mathematician student.

    Proof by infinite closeness: 3, 3.1, 3.14, 3.141, 3.1415, ... are all rational. Thus any decimal writing of pi will always be rational, no matter how many digits are used. Taking this limit as the number of decimals approaches infinity, we see that pi is rational.
