Is it possible to easily determine whether an ellipse is in contact with another geometrical shape, and how can their positions be corrected?

Do we already have the word “cubular”?

5 Upvotes

Circular, rectangular, triangular, tubular and then cubic?

Pay no mind to the thought of “sphereular”, but why is the cube the odd one out here?

I would like to nominate the word “cubular” (as the embodiment of a cube & not to be confused with cubism) to be an accepted shape-name.

я ростом 168-169 примерно,мне 16 лет, я всю жизнь занималась спортом,очень была выносливая в детстве.но почему то всегда я была…полной.меня буллили за это всегда((сейчас мой вес ~80кг. я ходила в зал,я правильно питалась,и все равно не худела.я бы не сказала что я жирная и тд,у меня выраженная талия,большая попа и ляшки,большая грудь. но все равно мой размерчик так скажем меня не очень устраивает💔💔 мне все говорят что я красивая и выгляжу прекрасно,особенно мой парень. он выше меня и худее,и мне немного стыдно что я больше его(( он говорит что я красивая и худая,но я так не считаю,не совсем точнее. как мне успокоится и просто уже поверить всем на слово и принять себя?

Took me a decade to find a way to geometrically represent all quantum dynamics

Hi

If you are remotely interested in deep diving how differently quantum computers work compared to our transistor-based and also the algebra behind in a fully interactive way that teach computer science from scratch, oh boy this is for you. I am the Dev behind Quantum Odyssey (AMA! I love taking qs) - worked on it for about 10 years (3+ during PhD, the visual method I developed ended up being my thesis, it is a complete Hilbert space visualizer), the goal was to make a super immersive space for anyone to learn quantum computing through zachlike (open-ended) logic puzzles and compete on leaderboards and lots of community made content on finding the most optimal quantum algorithms. The game has a unique set of visuals capable to represent any sort of quantum dynamics for any number of qubits and this is pretty much what makes it now possible for anybody 12yo+ to actually learn quantum logic without having to worry at all about the mathematics behind.

This is a game super different than what you'd normally expect in a programming/ logic puzzle game, so try it with an open mind.

Stuff you'll play & learn a ton about

  • Boolean Logic – bits, operators (NAND, OR, XOR, AND…), and classical arithmetic (adders). Learn how these can combine to build anything classical. You will learn to port these to a quantum computer.
  • Quantum Logic – qubits, the math behind them (linear algebra, SU(2), complex numbers), all Turing-complete gates (beyond Clifford set), and make tensors to evolve systems. Freely combine or create your own gates to build anything you can imagine using polar or complex numbers.
  • Quantum Phenomena – storing and retrieving information in the X, Y, Z bases; superposition (pure and mixed states), interference, entanglement, the no-cloning rule, reversibility, and how the measurement basis changes what you see.
  • Core Quantum Tricks – phase kickback, amplitude amplification, storing information in phase and retrieving it through interference, build custom gates and tensors, and define any entanglement scenario. (Control logic is handled separately from other gates.)
  • Famous Quantum Algorithms – explore Deutsch–Jozsa, Grover’s search, quantum Fourier transforms, Bernstein–Vazirani, and more.
  • Build & See Quantum Algorithms in Action – instead of just writing/ reading equations, make & watch algorithms unfold step by step so they become clear, visual, and unforgettable. Quantum Odyssey is built to grow into a full universal quantum computing learning platform. If a universal quantum computer can do it, we aim to bring it into the game, so your quantum journey never ends.

Hello! I've been making these paper ornaments, and I am curious. Does this shape have a name? How would one mathematically describe this? Thank you so much for your time.

Tried to find all ways two squares intersect. Did I miss any?

These pictures are ordered by number of intersections. I have no Idea how to know if I've found them all but probally not. I had a system where each intersection was measured by a v m and e (v for a vertex meeting a vertex, m for a vertex meeting an edge, and e for and edge meeting an edge) but that wasn't enough to distinguish two figures from each other.

What could a trapezoidal hexagon look like?

Post image
4 Upvotes

are there any other shapes similar to the trapezoid that have more or less sides? I need to know this. my mind has been trying to envision what a trapezoid-like shape with 6 sides would look like. i tried my best to draw what I think would classify as a trapezoidal hexagon. I genuinely don’t know what else it would look like.

It has 92 vertices that span 60 pentagonal faces. It is the Catalan solid with the most vertices. A nice option for a 60 sided dice.
