Prime numbers have a unique place not only in mathematics but in day-to-day life. The odd presence of a number that cannot be divided by any number apart from itself. There are many examples in biology where prime numbers drive special attributes of organisms ability to differentiate themselves. Marcus du Sautoy ran a fascinating program last year on BBC in the UK. The first few primes are 2,3,5,7,11,17 & 19.
The number seven has always fascinated me. I began to notice many stories that included the number 7 as a central character. But I also began to notice there were many stories with 3 and 5 as well and i’ll write some of these stories another time. Getting back to the number seven here are just some of the stories and occasions that you will know so well.
- The seven ages of man
- The seven wonders of the world
- Rainbow have seven basic colours (Red, Orange, Yellow, Green, Blue, indigo & Violet)
- Seven days in a week
- Seven intervals in music
- Seven visible Planets
- Seven basic directions
- Noah’s dove returned after 7 days
- Egyptians has seven paths to heaven
- King Solomon had seven steps in front of his temple
- The bible depicts the would was created in seven days
- Seventh heaven
- Seven deadly sins
In addition Christopher Booker writes in his classic on storytelling that there are seven basic plots that we use in stories. He outlines that all stories boil down to plots based on: Overcoming the monster, Rags to Riches, The Quest, Voyage and Return, Comedy, Tragedy and Rebirth.
So its strange that the number seven is a unique number as a prime and that there are so many examples where the number seven is so central to a story. There is something subliminal, and buried inside us that relates the number seven but I’m sure if your story has a rule of seven around it will resonate.
