MegaFavNumbers: Plus One Primes, 154,641,337, and 62,784,382,823
My entry in the #MegaFavNumbers series looks at a particularly striking example of a very specific family of primes -- and how it connects to what digits can be the final digit of primes in different bases.

An easy intro to prime numbers and composite numbers that MAKES SENSE. What are prime numbers? A prime number is a number that has exactly 2 factors: two and itself. What are composite numbers? A composite number is one which has two or more factors. What is the difference between a p

1,010,010,101,000,011 - #MegaFavNumbers
This is my submission to the #megafavnumbers project. My number is 1010010101000011, which is prime in bases 2, 3, 4, 5, 6 and 10. I've open-sourced my code: https://bitbucket.org/Bip901/multibase-primes Clarification: by "ignoring 1" I mean ignoring base 1, since this number cannot be fo

In this video, I use the coordinate method or Chain Rule method to solve a PDE. It is based on defining clever coordinates and using the Chain Rule to turn the PDE into one that's much easier to solve. Enjoy! Check out my PDE Playlist: https://www.youtube.com/playlist?list=PLJb1qAQIrmmDo

Distance squared on disk and square
In this video, I answer the following neat question: If you have two points on a circle, then what is on average the distance between them? This problem can be surprisingly (or not) solved using multivariable calculus by converting it into a quadruple (!) integral! Then, I solve the same p
