How small would a calculator have to be to become a black hol?

I must understands what yoctometer length look lik.

Enigma 618: Mysterious divisor

This was a very complicated yet fun-to-do problem. The answer will be posted next.

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 →

Copeland and Erdős and a constant

Please send me a guide on how to pronounce Erdős. Please.

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 →

Joseph Liouville and his Numbers (especially his constant)

Number theory. Whoo! In number theory, let there be a number x where, for any positive integer n, there are infinitely many number pairs (p, q) where q > 1 that: 0 < |x - p/q| < 1/q^n x is the Liouville number. Liouville numbers can be described as "almost rational", and can be approximated … Continue reading Joseph Liouville and his Numbers (especially his constant) →

P/NP?

Back to another Millennium Prize problem! There are two types of questions: one, where an algorithm can solve the question in polynomial time (P), and ones, where there is no way to find the answer quickly, but if information is given on showing what the answer is, it can be quickly verified, which is NP, … Continue reading P/NP? →

Poincaré Conjecture… with less detail.

Yes, this was already solved by Grigory Perelman, but I have nothing much, so... Imagine a spherical item. And, for the easiest solution, let's use an apple. Wrap the rubber band around the apple. Without tearing it or letting it leave the surface, we can slowly shrink the rubber band until it becomes a single … Continue reading Poincaré Conjecture… with less detail. →

Riemann Hypothesis

Yesterday, I said that I would do a post on the Riemann Hypothesis, so here we are now. There is a function with the name of the Riemann Zeta Function, named after Bernhard Riemann. The Riemann Hypothesis states that the Riemann zeta function has zeroes only at the negative even integers and complex numbers with … Continue reading Riemann Hypothesis →
