Credits to Numberphile for the information. 3. It's a really basic number, isn't it? Right? WRONG!Kevin, Vsauce2 There's many things you can do with 3. For example, add itself together three times: 3 + 3 + 3 = 9. That's 3 * 3. But 3 * 3 * 3 is 27, and that's 3^3. We … Continue reading 3^3^3^3^3^3^3^3^3^3^…^3^3^3^3^3^3^3^3^3^…^3^3^3^3^3^3^3^3^3^…^3^3^3^…^3^3^3^3^3^3^3^3…

Happy Tau Day!
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!
A big number that shrinks down to about three
I remember this from a book. The puzzle is: The sum of the factors of 360 is 1170. What is the sum of the reciprocals of the factors of 360? At first glance, it might seem impossible to solve, but when you look at it deeper, it's easy. Let's do the classic: 1/1 + 1/2 … Continue reading A big number that shrinks down to about three
There is a very hard, very hard…
Hey, it's the lousy author, back with another extraordinary enigma puzzle, and I do have to say, Uncle Bungle is really messed up.
Reuleaux and its relation to triangles
Now, it's not pronounced like Rolex, but more like rulers. I don't know why, but it is. What are Reuleaux triangles? Think of two circles overlapping with each other, with the centre of one circle being on the other circle. Now add another circle with one of the overlaps being the new circle's side. Did … Continue reading Reuleaux and its relation to triangles
Math is very biased
Imagine two people got married to each other and had two children. If one is a girl, what is the probability that the other child is also a girl? Instinctively, you should respond "1/2!" and you're right. Except... you're not. Think of all the possible ways that a girl could be in the family. There's … Continue reading Math is very biased
Collatz by Lothar Collatz
I am not creative. The Collatz Conjecture states that for any positive integer n, the Collatz sequence will eventually reach 1. The Collatz sequence is: Yee So if n is even, divide it by two, and if n is odd, multiply it by three and add one. So, for example, 36, 18, 9, 28, 14, … Continue reading Collatz by Lothar Collatz
The Life Game: Coming soon in 2096
DISCLAIMER: I said I would do a post on normal numbers. Tomorrow. Promise. Before I start, I would like to say that I own none of the images and gifs. They are all by Wikipedia. I already did a post on Conway's Game of Life, but it was years ago and I wasn't very good … Continue reading The Life Game: Coming soon in 2096
Abraham de Moivre and formula
De Moivre's formula states that (cos x + isin x)^n = cos nx + isin nx. Where i is the imaginary number √-1. Now, for proof and simplicity's sake, let's change cosx + isin x to cis x. This is a proof by induction, as stated by Wikipedia (I use a lot of Wikipedia these … Continue reading Abraham de Moivre and formula
