Ty! Rectangles are 2-dimensional cuboids, a square is a special rectangle. The 2 sides a & b of a rectangle relate to its diagonal as follows: a²+b²=c² c=a+d a=d(m²-1)/2 b=dm c=d(m²+1)/2 d=2,m=6 35²+12²=(35+2)² d=4,m=3 16²+12²=(16+4)² d=6,m=2 9²+12²=15² d=8,m=3/2 5²+12²=13² I hope this is useful.

Paul Arnheim-Projekt @paula-projekt.bsky.social

Any (!) pythagorean triple a natural number belongs to. Thank you for asking! Every natural number >2 belongs to at least one Pythagorean triple a, b, c with a²+b²=c². See #ALText for some examples. The 1st Shalan theorem is lazybones's darling because it's shockingly simple, isn't it?

The screenshot reads: Every natural number >2 belongs to at least one Pythagorean triple a, b, c with a²+b²=c². a equals d(m²-1)/2, b equals dm, and c(=a+difference d between a and c) equals d(m²+1)/2. This simplifies the calculation, because you only have to square m! Example: dm=12 d=8, m=1.5 =>a=5,b=12,c=5+8 5, 12, 13 is a primitive Pythagorean triple. d=6,m=2 =>a=9,b=12,c=9+6 d=4,m=3 =>a=16,b=12,c=16+4 d=2,m=6 a=35,b=12,c=35+2 12, 35, 37 is another primitive Pythagorean triple. If the starting natural number is odd, it could also be the hypotenuse c. Example 17: d=1, m=17 =>a=144, b=17, c=144+1 17, 144, 145 is a primitive P triple. If 17=d(m²+1)/2, d must be an even number. =>d=2, m=4 a=15, b=8, c=17 is a primitive triple too.

I was also once interested in Mathematics, but all these problems seem absurd to me, having no practical application. Knowing that there is a solution to this equation a²+b²=c² does not give us anything in principle.

Well, vector calculus is essentially based on the Pythagorean theorem. The magnitude of a vector is determined this way. This is important wherever one deals with directional phenomena. The Pythagorean theorem is far more than just a theoretical gimmick!

In general, a square is an area, there is just an exact coincidence in the numbers - a square with a side of 3 m + a square with a side of 4 m = a square with a side of 5 m.

There is an exact agreement in the numbers if and only if the squares are arranged in such a way that one of their sides form the two sides a and b and the diagonal c of a rectangle, in other words, three sides of three squares form a right-angled triangle.

For comparison, these are conventional methods for generating Pythagorean triples: en.wikipedia.org/wiki/Pythago.... None of them is as beguilingly simple as the first Shalan theorem (d(m²-1)/2)²+d²m²=(d(m²+1)/2)².

There is more of it since polynomials are just building instructions for n-dimensional cuboids. The 1st derivative equals half of the boundaries of such a cuboid. Epsilon go home! How to find the x value of the vertex/middle inflection point easily f(x)=a1x^n+a2x⁽n-1)+...+a(n+1)x⁰ It is -a2/n*a1

This LEGO cuboid represents f(x)=(x+0)(x+3)(x-1) =x³+2x²-3x the + sign represents the directions forward and right, the - sign represents drawn with this ingenious tool/toy: https://www.matheretter.de/rechner/gfplot Calculus of f(x)=x³+2x²-3x (blue graph), f'(x), pink, f''(x), turquoise, f'''(x), green, F(x), purple 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?

Religion serves the clergy's self-enrichment (Numbers 28) and self-aggrandizement (Leviticus 21:8). For this to work, science has to obey and must be suppressed . It is therefore just like in a marriage recommended by all leading religions, in which the woman is oppressed by her owner (sic).

You don't learn this at Sunday school, do you? Or this: 1 Cor 16:1-4 with the invention of the convenient install payment for donations to "the poor saints of Jerusalem". Or this: YHWH, the famous Tetragrammaton, equals Y+HWH with HWH happens to be "Eve", MOTHER of all living (Genesis 3:20). Oops.

source: https://www.biblegateway.com/passage/?search=1%20Corinthians%2016%3A1-4&version=NCB The screenshot reads: VIII: Final Recommendations and Greetings[a] Chapter 16 The Collection. 1 Now in regard to the collection for the saints,[b] you should follow the instructions I gave to the churches of Galatia. 2 On the first day of every week,[c] each of you should set aside and save whatever you can spare, so that when I come to you, no collections will have to be taken. 3 And when I arrive, I shall send those who have been approved by you with letters of recommendation to deliver your gift to Jerusalem. 4 If it seems advisable that I should also go, they will accompany me. Read full chapter Footnotes 1 Corinthians 16:1 The collection for the Church of Jerusalem—the “saints”—had an important place in Paul’s outlook, because it was a sign of communion between the Churches that originated in the Gentile world and the mother Church that had grown up at the heart of Judaism (see Acts 24:17; Rom 15:25-26; 2 Cor 8–9; Gal 2:10). 1 Corinthians 16:1 The saints in Jerusalem were obviously in dire need—possibly as a result of the famine recorded in Acts 11:28 (about A.D. 44 or 46) or the persecution to which they were subjected (Acts 8:1). 1 Corinthians 16:2 On the first day of every week: i.e., Sunday, the Lord’s Day (see Acts 20:7; Rev 1:10). Each of you should set aside: each Sunday Christians were to bring what they had set aside for the Lord’s work. It was then probably collected at the worship service. Justin Martyr indicates in his Apology (1:67-68) that during his day (c. A.D. 150) offerings were brought to the altar on Sundays.

Thank you so much! I'm sorry that I didn't see your reply earlier. And indeed, the universe does speak through numbers, e.g. phi, the Golden Ratio 1.6180... that is omnipresent in nature.

The parabola, drawn with this ingenious toy/tool:https://www.matheretter.de/rechner/gfplot, is f(x)=1x2-1x-1, its roots or zeros are x1,2 (1-5⁰·⁵)/2 and (1+5⁰·⁵)/2 with x2 happens to be phi, the Golden Ratio. Fibonacci number ratios are 1, 1,5, 5/3, 8/5, 13/8 with n/(n+1)+1=(n+1)/n => n+n+1=(n+1)²/n 2n²+n=n²+2n+1 n²-n-1=0 which leads to the function f(x)=x²-x-1 Square addition: (x-0.5)²=x²-x+0.25 =>f(x)=(x-0.5)²-1.25 1.25=5/4 (5/4)⁰·⁵=x-0-5 x1,2=(1+/-5⁰·⁵)/2

Hi I’ve changed my bluesky handle to my name jamiannass.bsky.social now that America and the election failed. I’ll be using it a lot more now that Zuck has “unable to post” me on Threads from calling MAGA stupid! Please follow me at my new bluesky name. Thanks.

You shouldn't be surprised. Facts are not vegan; It's not cool to poison debates with them.

As a former Lego sculptor (solid color / pure plasticity) I've got to say this is brilliant work.
