April 13 2022 - So Many Luckies

 

The world of Mathematics is very active. Here is something that we didn't learn about in school because they were new ideas at the time I went to school.  The term is lucky number, and was introduced in 1956. I found it asking myself this question: What if I would like more than just the lucky number seven.? From Wikipedia:  In number theory, a lucky number is a natural number in a set which is generated by a certain "sieve". This sieve is similar to the Sieve of Eratosthenes that generates the primes, but it eliminates numbers based on their position in the remaining set, instead of their value (or position in the initial set of natural numbers). Wikipedia shows us how it works with an animation.  I've captured a screen shot just at the end of the elimination game.  You can go to the Wikipedia entry HERE to see the animation and read the process.  Wouldn't it be nice to have a lucky number set each day and find their occurrences.  1, 3, 7, and 9 today.  Would this be a sort of game of synchronicity?  Synchronicity describes circumstances that appear meaningfully related yet lack a causal connection.  There are more interesting named numbers - fortunate number (a person's name), abundant number, lucky numbers of Euler, Happy number, Harshad number are a few.
