I've been making plots of the sets of roots of some polynomials. They look more interesting than I'd expected! And I've been making sounds from them, too. I have a bunch on this page of my website (I'll probably be adding more). Click on the images to embiggen them, and if you're in a hurry, the […]
This LEGO cuboid represents f(x)=(x+0)(x+3)(x-1) =x³+2x²-3x ( blue cube x³+ red cuboid 3x²+ white cuboid -1x² + white cuboid 3*-1*x. The + sign represents the directions forward, right and up, the - sign represents backward, left and down. Half of its surface equals 3x² (blue squares) +2*3x (red rectangles) + 2*-1x (white rectangles)+ 3*-1*x (white rectangle) =3x²+4x-3; Epsilon, eff off ; ) A cube has six boundaries, squares. So the derivative f'(x) of f(x)=x³ equals 3x². A square has four boundaries, edges. Therefore the derivative of f(x)=x² is f'(x)=2x. An edge has two boundaries, points. So g'(x) equals 1, if g(x)=x. Points have no boundaries: no boundary, no derivative. (A tesseract has eight boundaries, cubes. Half of them are 4x³ etc.

Calculus of polynomials without epsilon Half of the boundaries of an n-dimensional cuboid represent the slope of the graph of the corresponding function! One x² represents one third of half the boundaries of a cuboid AND the area between function graph and x-axis, the antiderivative. It is shockingly simple, isn't it?

A plot of all roots of all 15th degree polynomials with terms ±1/(n+1)x^n. The roots are tiny blue dots on a white background. They form a ring around the origin at the center of the plot, with something like fractal filigree around the outside of the ring. The roots are symmetric: each quadrant is identical.

Visualization of the famous Yang Hui or Pascal Triangle, dimensions 0, 1, 2 (relevant for the Pythagoras theorem 2.0) and 3 In the not yet published novel "Fluten", a combination of thriller and textbook, the characters Sheldon and Hasan, students at the fictional University of Aachen, develop this elegant formula and call it the first Shalan theorem. In German, “Fluten” has a double meaning. It is both the plural of flood and a verb. Pythagoras: a²+b²=c² =a²+2ad+d² =(a+d)² Cheap trick: Outsourcing of d² leads to d²(2a/d+1), 2a/d+1 becomes m² Solve for a 2a/d+1=m² a/d=(m²-1)/2 a=d(m²-1)/2 First Shalan theorm (d(m²-1)/2)²+d²m²=(d(m²+1)/2)² Take any natural number >2 and call it dm. "d", as the distance between a and c, must be natural. But not "m" which must be >1. HERE I FORGOT SOMETHING IMPORTANT; SOME PRIME NUMBERS CAN BE THE HYPOTENUSE! 17=2(4²+1)/2 So m=4, d=2 In this case d must be even. The great thing about this quadratic formula for lazy people is that all you have to do is square m! And this is how it works: Let dm=24 Find two factors that give the product 24 d=12, m=2 (12(2²-1)/2)²+24²=(12(2²+1)/2)² =>18²+24²=(18+12)² =30² d=18,m=4/3 (18(16/9-1)/2)²+24²=(a+d)² 18(7/9)/2=7 =>7²+24²=25² 7,24,25 is a primitive Pythagorean triple. With d=2,m=12, you get the other primitive triple 24,143,145: 143²+24²=145² d=16,m=3/2 8(9-4)/4=10, 10²+24²=26² d=8,m=3 32²+24²=40² d=6,m=4 45²+24²=51² d=4,m=6 70²+24²=74² If dm is a prime number, d must be 1: dm=17 => 288/2=a, 144²+17²=(144+1)² This is shockingly simple, isn't it?
This is just a screenshot of the alternative text of the photo that shows a visualization of the Yang Hui or Pascal Tringle, dimensions 0, 1, 2, 3.. I FORGOT SOMETHING IMPORTANT; SOME PRIME NUMBERS CAN BE THE HYPOTENUSE! 17=2(4²+1)/2 So m=4, d=2 In this case d must be even.

My screenshot reads: Today I have one of my Cassandra days. But my truth, which no one wants to hear, is such a beautiful one. And I wouldn't have pushed Apollon off the edge of the bed. For Pythagoras 2.0 you only need a single number greater than two and you can immediately tell which Pythagorean triples it belongs to! This is so much less complicated than the traditional methods. And you only have to square one number. Which doesn't always have to be natural! The Shalan theorems deserve more attention. Pythagoras theorem: a²+b²=c² 1st Shalan theorem d(m²-1)/2 as "a" dm as "b", d(m²+1)/2 as "c" with c=a+d In my pinned tweet I was guilty of an omission: prime numbers can not only appear as legs of right-angled triangles, but some can also become hypotenuses. I forgot to mention that. Those prime numbers, successors of even square numbers (16+1=17)* or half of the successors of odd square numbers ((25+1)/2=13)**, can be a hypotenuse; If so, d must be even. *d=2,m=4: 2(4²-1)/2=15 => 15²+8²=17² **d=8,m=3/2: 8(9/4-4/4)/2=5 => 5²+12²=13²
Hi fam,
have a fulfillig day!
I hope that this reaches many users; The three Shalan theorems and the consequences - that #polynomials are just building instructions for n-dimensional cuboids - can revolutionize #mathematics #teaching.

His work makes interesting progress on the long-standing Aaronson-Ambainis conjecture at the intersection of #quantum computing and #Boolean function analysis. Thanks to Sreejata, we now know this conjecture is true for random restrictions of bounded #polynomials.
A problem about the irreducibility of a polynomial (Cyclotomic polynomial). This is traditionally proved by using Eisenstein's criterion. Here we use the technique of "reduction modulo p".

The cuboid made of LEGOs represents f(x)=(x+0)(x+3)(x-1) =x³+2x²-3x. It is made of a blue cube x³, a red cuboid 3x², a white cuboid -1x² and a white cuboid 3*-1*x. The + sign represents the directions forward and right (and up), the - sign represents (backward, left and) down. So f(x) becomes x³+3x²-1x²-3x=x³+2x²-3x Half of its surface equals 3x² (blue square)+2*3x (red rectangles) + 2*-1x (white rectangles)x+3*-1 (white rectangle)=3x²+4x-3. The slope of the function, the first derivative, can be described by half of the surface of the cuboid; Epsilon go home ; ) Half the boundaries of a square are 2x, so the slope of g(x)=x² is simply g'(x)=2x. Half the boundary of an edge x is one point 1. If there are n/m edges, the slope is represented by n/m One cuboid represents only one fourth of half the boundaries of a four-dimensional cube. Therefore the anti-derivative of h(x)=x³ is H(x)=x⁴/4. One x² represents only one third of half the boundaries of a cube. The anti-derivative of i(x)=x² is I(x)=x³/3. And so on. Bonus feature: You can find the x-value of middle inflection point or the vertex easily; This is how it works: f(x)=a1x^n+a2x⁽n-1)+...+a(n+1)x⁰ The x-value of the vertex/middle inflection point is just -a2/n*a1. The x-value of the onlyinflection point of f(x)=1x³+2x²-3x is -2/1*3=-2/3 It's shockingly simple, isn't it?
Calculus of f(x)=x³+2x²-3x (blue graph) f'(x)=3x²+4x-3, pink, equals the first derivative and describes the slope of f(x) At the point (-2/3;f(-2/3)) the slope of f(x) is minimal. f''(x)=6x+4, turquoise, 2nd derivative, describes the slope of f'(x), f'''(x)=6, green, the 3rd derivative, describes the slope of f''(x) F(x)=x⁴/4+2x³/3-3x²/2+c, purple, is the anti-derivative of f(x) and describes the area between the graph of f(x) and the x-axis.
