  1. didn't discover the . Publishers of English math books know this and won't correct it. Oh, and Christopher Columbus discovered America. = 🜂

  2. Als je het tijdens het eten met je 12-jarige aan de stok krijgt, omdat ze weigert tuinbonen te eten, en ze zegt "Pythagoras hield ook niet van tuinbonen.", dan heeft ze waarschijnlijk gelijk.

    Het is misschien tijd om haar boekenleeshistorie in de bieb eens te bekijken.

    Maar inderdaad, het verhaal gaat dat Pythagoras niet van tuinbonen hield.

    Ik zou een punt honoreren voor de 12-jarige, want die is onderweg naar een toekomst 😁
    Extra toetje.

  7. 📐 #Mathematik

    Die Katheten a & b im 90°-Dreieck: a² + b² ergibt exakt die Fläche des Quadrats über der Hypotenuse c. So findest du fehlende Strecken beim Bauen, Zeichnen oder Zocken. Immer gültig, solange der Winkel recht ist! #Pythagoras #Mathe #Lernen

  8. 📐 #Mathematik

    Warum gilt a²+b²=c²? Stell dir auf den Seiten eines rechtwinkligen Dreiecks Quadrate vor. Die beiden kleinen Flächen lassen sich ohne Lücke in das große schieben – 3²+4²=5². Nützlich für Bau & Games! #Pythagoras #Mathe #Lernen

  16. According to the biography by Diogenes Laertius, Pythagoras (c.570–c.490 BCE) ‘held that the most beautiful figure is the sphere among solids, and the circle among plane figures’.

    This aesthetic preference for the circle and sphere can be traced through thinkers like Plato (who, according to later writers, set the problem of describing the movements of the heavens using uniform circular motions), Cicero (106–43 BCE), and Proclus (410/12–485 CE), and into the middle ages.

    Thomas Bradwardine (1290/1300–1349), one of the mediaeval ‘Oxford calculators’, was obviously influenced by this tradition when he wrote that the circle ‘is the first and most perfect of figures, the simplest and most regular, the most capacious and the most beautiful of figures’.

    But Bradwardine then presented evidence that he saw as attesting to the beauty and perfection of the circle: (1) the construction to find the centre of a circle by bisecting a diameter found as the perpendicular bisector of a chord; (2) that the intersections of six equally-spaced radii with the circumference define a regular hexagon; (3) that exactly six circles of equal size can touch a given circle (see attached image).

    For Bradwardine, the perfection of the circle was thus linked to the perfection of the number 6 = 1+2+3: the construction involves six intersections with the circle; the hexagon is made up of six lines; the third result involves six outer circles.

  22. My favorite ways to frame some of the most interesting (counterintuitive) facts about high #dimensional #geometry.

    1. Cubes are Caltrops. (yes, #dnd reference)
    2. Spheres are tops. (the tops you spin, thin on both ends, fat in the middle)
    3. Mangoes > Oranges (but only in high dimensions, in 3D I prefer oranges)
    4. Orthogonality (I don't have a catchy way of saying this. Upstanding vectors?)
    5. Orthogonal everywhere (when dimensions are #infinite)
    6. Unit sphere vectors are tiny (their coordinates are mostly very small; yes I know the statement as is, is wrong)

    Caltrops is simply a consequence of my (everyone's?) favorite theorem about right angled triangles: #Pythagoras theorem.

    Consider the unit cube in 𝑛 dimensional space. The circumradius, via repeated application of Pythagoras, is equal to √𝑛. On the other hand, the inradius is fixed at 1/2.

    This gives rise to the pointy cubes visual for high dimensions. The vertices/corners of the unit cube will shoot out compared to the unit circle, despite the faces of the cube staying close.

    I've also heard this referred to as "cubes in high dimensions are sea urchins." I like both names, but caltrop is just a fun word to say.

    The remaining facts are consequences of exponential decay, which I'll go through in the next post in this thread.

  23. Delightful!

    #MathsMonday #Maths #Math
    I was reminded this week about the #algebraic #Mathematics #proof of #Pythagoras theorem, which I always thought was pretty cool, so I thought I'd share it this week for those who haven't seen it. I'd seen the one where you cut out shapes, but I always found that one a little boring, but being a numbers person I really liked this proof, when I finally saw it!

    You'll see in the image we have a big square which is made up of 4 triangles and a smaller square...

  26. @Miriamm Has anyone from the mathsy Fediverse been able to see the proof yet? Does it hold up? #mathstodon #mathtodon #pythagoras
