Yes, the time has come. The day when we all celebrate the sacred (not) circle constant, τ. Fun fact: if you Google "Tau Day", it's a real thing! So, τ. The number that is equal to 2π. Why is τ right and π wrong? Think of a circle with radius 1. Now, before I state … Continue reading Happy Tau Day!
I was sitting down, solving one of Catriona Shearer's geometry puzzles when I found this (by myself): Look, I know it's not the best of drawings, but it's what I did. If we call the long diagonal x, and the line segment perpendicular to the diagonal y, then the area of the triangle = xy/2, … Continue reading A neat way to calculate the area of a rectangle
You know angles? Like this? Angle That's two dimensional. What about an angle in three dimensions? four? five? one? To our 4-dimensional friends out there, tell us the answer!!!!!!!!! comment plz!
DUN DUN DUUUUUUUN!!!!! Okay, okay, the Tangram is not a monster, you are assured of that. It's a kind of puzzle, but also a toy. It is: A tangram And you can split the seven parts up and put them together in fun ways. Like: The number 4 You can go ahead and search it … Continue reading The Tangram
Say WHAT?!?! You probably were freaked out by that. There hasn't been a post on topology and I want to do one. So ... here comes nothing. To explain the topology and potatoes, we have to use topology, but before that, what even is topology? Topology is an area of mathematics where a pencil is … Continue reading Topology = potatoes
Did anything stand out? maybe the m^2+n^2 = f^2 bit? That is Pythagoras's theorem. That? This is what it's like: Pythagoras's theorem, in triangles and squares Link: https://upload.wikimedia.org/wikipedia/commons/thumb/d/d2/Pythagorean.svg/260px-Pythagorean.svg.png Pythagoras's theorem states that, if the triangle is a right-angled triangle, a^2 + b^2 = c^2. Sure, this is one proof: prove it! Link: https://i.stack.imgur.com/POhH1.png But for … Continue reading Pythagoras’s theorem^2+n^2 = proof^2
Now this is awesome, and you can make a hexaflexagon out of food! The video below shows you how to make it. (Note: ingredients may vary) https://youtu.be/GTwrVAbV56o Tasty ... I can't really describe how to make one of these, so I'll leave all the explanations to the video. https://youtu.be/Svq2Kscmmwc Back in the days ... Enjoy! … Continue reading How to create the awesome hexagon to entertain you Part 4
We have seen Richard Feynman and John Tukey. They are 2 of the other people who collaborated with old Arthur and Bryant. No, the Feynman diagram doesn't relate to hexaflexagons. Thank you Martin Gardner for the awesome Scientific American article. And double thank you for the awesome book Mathematical Games. It needs to be read. … Continue reading How to create the awesome hexagon to entertain you Part 3
Have you seen the video? Good. Now, if this is the first video you've seen about hexaflexagons, then you'll probably be like, "Who is this Bryant Tuckerman?" Who is this Bryant Tuckerman?Our readers who didn't know what Hexaflexagons are Yes, yes, thank you. Bryant Tuckerman (no, NOT Bryan) was one of the people who collaborated … Continue reading How to create the awesome hexagon to entertain you Part 2
Hexagons. They are 6-sided, hexagonal, and boring. HALT! HALT! Who are you?The Twelfth Doctor Well, I am the author of this post. Anyway, the hexagon's boringness depends on what kind of hexagon it is. If it is a normal paper hexagon, the hexagon is at the top, 10. For silk or sewing materials, that's a … Continue reading How to create the awesome hexagon to entertain you Part 1
