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. "May the force (duality) be with you" -- Jedi teaching.

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.

Somewhere out there in this world.

If back in the past, people kept great discoveries secret, now it could be possible that someone out there made a discovery but isn't confident about their own ability to explain it. I mean, we already got the internet. If a person thought of something, they could search the internet for answers, or to confirm something. If it doesn't show up, it may be because it was a stupid idea that noone ever considered it, or it may have not existed considering them to be the first to come up with it. It is possible that the latter could happen. It's not such a bad situation though because some other people could just come up with the same idea, until one actually is confident enough to go public with it. Same with the story in this vid.

@hainesensei8118 Год назад

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.

When things were at their very worst: 2 Suns, Cross in the sky, 2 comets will collide = don`t be afraid - repent, accept Lord`s Hand of Mercy. Scientists will say it was a global illusion. Beware - Jesus will never walk in flesh again. After WW3 - rise of the “ man of peace“ from the East = Antichrist - the most powerful, popular, charismatic and influential leader of all time. Many miracles will be attributed to him. He will imitate Jesus in every conceivable way. Don`t trust „pope“ Francis = the False Prophet - will seem to rise from the dead - will unite all Christian Churches and all Religions as one. One World Religion = the seat of the Antichrist. Benedict XVI is the last true pope - will be accused of a crime of which he is totally innocent. "Arab uprising will spark global unrest - Italy will trigger fall out" "The time for the schism in the Church is almost here and you must get prepared now." The Book of Truth.

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.

@@yuseisatouissuffering they shouldn't be supposed to memorize the history . It should just be told to inform them on how maths is actually done, i.e. how new stuff is actually figured out.

You can't stop the enlightenment (which is a merit to Italians) even with all the personal drama of Italian mathematicians. 3. Never underestimate the value of an entertaining story to teach what is a complex, boring subject at a first glance.
