In this video I go over the sum of the series whose terms are reciprocals of the positive integers whose only prime factors are 2s and 3s. Recall that a prime number is a number that can only be divided

HIVE recently attracted a professional mathematician with the handle @petreius who published a paper on the distribution of Twin Primes. So, I decided to take a short break on philosophy to pen a post

Twin prime conjecture

Microgrid is my project, designed for distributed calculations in browser. Uses JavaScript for calculations and Gridcoin for rewards (but you also leave them in project, as your score points). Current

I created new project. It calculates specified function in your browser with arguments given by server. Server saves results and send new task for you. Currently it checking is number prime or not. But

In 1874 Stanley Jevons realised the existence of trapdoor functions. The multiplications of two primes is a very easy task. But given the product it is very hard to figure out which two primes were used.

Today I was revisiting a prime number spiral I saw by Joey Grether a couple years ago that was disguised as a Nikola Tesla document. I think the spiral works better with 6 as you can see in the image above.

New project. Create a big prime spiral. With haskell, I produced all primes under 10000. Let's see if we can put in all of them. Here is the code I used. isprime p= null [p | a<-[2..p-1], b<- [2..p-1],

The "CRUNCHATHLON PG [MONTHLY RUN - RACE XVII]" challenge has started: 2017-09-10 17:00 UTC - 2017-09-14 17:00 UTC 16 BOINC teams have signed up so far What do you need to do?        

The BOINC project PrimeGrid, which is also whitelisted as research project for Gridcoin, needs help: "If anyone has connections with a corporation, university, cloud  provider, or rich uncle that

Prime numbers form the basis of our entire number system. Yet there seems to be no ordering to them at all. They appear to occur randomly. However, a Polish mathematician named Stanislaw Ulam may have
