    I have a masters degree in physics, so I'm confident in saying I'm pretty good at maths. You describing the completing the square method of solving a quadratic just genuinely blew my mind. I never understood where any of it was coming from and opted instead just to use the quadratic formula and ignore completing the square. I just thought it was entirely irrelevant. But holy wow it makes so much sense now, I see where the steps all come from, and it's actually extraordinarily elegant. It makes soo much more sense now!

      @hainesensei8118 년 전 +5

      This comment got a lot longer than I initially intended, but covers a number of things about constructions of the complex numbers and how else they can be thought of:
      As a pure mathematics student, I like to think of imaginary numbers as a construction. They are not “numbers” in the same sense as real numbers, but they can be paired with real numbers to produce a helpful construction which allows people to manipulate things in ways that may not initially seem possible. In the context of ring theory, we consider general systems of numbers with addition and multiplication. You can add and multiply polynomials with coefficients from any given ring as one might expect. And it turns out that a construction basically the same as imaginary numbers appears when you “quotient” the polynomial ring of the real numbers by “the ideal generated by” X^2 + 1. If you’re not familiar with this language, that basically means that if you take this ring, but now consider that whenever X^2 + 1 appears (or any of its multiples), it is now considered to be 0. You can see that this can produce the complex numbers intuitively since we are essentially just treating X as a number which squares to -1. Which is exactly equivalent to this idea behind the complex numbers: allowing the number i to exist and square to -1. All the properties of rotation then naturally appear through all the classical studies of complex numbers.
      However, a possibly interesting idea from this is that if instead someone had decided that they wanted a *different* cube root of 1, let’s call it j. Then j^3 = 1, and (-j + 1)^3 = -1 + 3j^2 - 3j + 1 = 3j^2 - 3j. But noting that j^2 = 1/j (and allowing some algebraic manipulation with some extra assumptions), we can find that (-j + 1)^3 = 1 as well (which matches what you’d get if you treated j as either of the complex cube roots of unity). I think we can all be pleased that no one did find this, because working with this number is a lot more tedious than working with complex numbers as we know them, but it does work.
      From the ring theoretic perspective, for this construction we wouldn’t set X^3 + 1 = 0, but instead we’d use X^2 - X + 1 = 0 which is (X^3 + 1)/(X - 1). This is basically so that we don’t have worries about X actually being 1. Obviously this comment misses out on a lot of rigour, but is intended to provide the general intuition behind the fields mentioned and give an alternative perspective of complex numbers.

      That would require _good_ math teachers, though. You only get those at the graduate-school level, because that's where they all end up. The teachers who end up teaching algebra, geometry, and trigonometry in grade-school are the people who just barely graduated with their math degrees -- they aren't qualified to teach anything harder than "x + 5 = 10" or "sohcahtoa". Whereas anything _simpler_ than algebra, geometry, and trigonometry doesn't require a math degree to teach it _at all,_ so there's nowhere lower for those bottom-tier math teachers to go. So _every single kid's_ first introduction to math that requires _actual thinking_ (instead of memorizing tables) is with a math teacher who, objectively, sucks at math.

    One thing that was really cool about taking abstract algebra was when we constructed the field of complex numbers entirely from real numbers. It meant that the complex numbers were given a definition in terms of a previously understood set of number, which is how all numbers get there definition. (Except the cardinals which are the sizes of sets)

      Imho, this is how mathematics should be taught. Rather than throwing the conclusion and have students arbitrarily plugging in numbers; an introduction with a few key points in its discovery would go a long way to understand how one stems from another and create better understanding and thus foundation to the subject.

      Complex numbers are dual to real numbers.
      Perpendicularity or orthogonality = DUALITY!
      Column vectors are dual to row vectors -- group theory.
      Electro is dual to magnetic -- Maxwell's equations.
      The electric field is perpendicular (dual) to the magnetic field -- probability waves.
      Positive charge is dual to negative charge -- electric fields.
      North poles are dual to south poles -- magnetic fields.
      Electro-magnetic energy or photons are dual.
      Points are dual to lines -- the principle of duality in geometry.
      Group theory:- the image is a copy, equivalent or dual to the factor or quotient group.
      Isomorphism (absolute sameness) is dual to homomorphism (relative sameness or difference).
      Homo is dual to hetero, same is dual to different.
      Injective is dual to surjective synthesizes bijective or isomorphism.
      Positive curvature is dual to negative curvature -- Gauss, Riemann geometry.
      Curvature or gravitation is dual.
      Gravitation is equivalent or dual to acceleration -- Einstein's happiest thought, the principle of equivalence (duality).
      "Perpendicularity in hyperbolic geometry is measured in terms of duality" -- Universal hyperbolic geometry, Professor Norman J. Wildberger.
      Duality (energy) creates reality.
      Action is dual to reaction -- Sir Isaac Newton (the duality of force).
      Attraction is dual to repulsion, push is dual to pull -- forces are dual, e.g. the electro-magnetic force.
      Monads are units of force -- Gottfried Wilhelm Leibnitz.
      Monads are units of force which are dual -- monads are dual.
      Energy = force * distance.
      If forces are dual then energy must be dual. Potential energy is dual to kinetic energy, gravitational energy is dual.
      Apples fall to the ground because they are conserving duality.

      Obviously you simply just _can_ by moving from real numbers to imaginary ones. You need to be careful though, because after the switch not all of the arithmetic is the same. Especially when dealing with roots of arbitrary fractions, order of operation between powers and roots, and when dealing with (semi)inner products.
