My eldest daughter, Claire, turns 23 today. On one hand, it totally feels like 23 years have passed. Yet, her birth also seems like it just happened. The vagaries of time are interesting.
Claire hates to flip the page to a new age. When she turned four she cried because she was no longer three. While most kids celebrated turning 16, Claire was melancholy because of how old 16 sounded (but this was somewhat mitigated by 16 being her favorite number.) So, to help her maybe like being 23 a bit more, let’s dig into all the awesome things about the number 23.
1. Humans have 23 pairs of chromosomes, which is where the genetic testing firm 23andMe got its name. Claire loves 23andMe. Each parent contributes 23 chromosomes to their children.
2. Twenty-Three of course is a prime number, which is pretty cool. But what is cooler is that it’s the first prime that is made up of consecutive digits. And it’s the first prime in the 20s.
3. Some people believe that 23 has mystical powers (such people are commonly known as 23rdians). John Nash, the Noble Prize-winning mathematician who was biographies in the film “A Beautiful Mind”, was obsessed with the number 23 and he published 23 scientific papers.
4. Supposedly, Julius Caesar was stabbed 23 times.
5. Twenty-Three is a “happy number” which is a number that eventually reaches 1 when replaced by the sum of the square of each digit. The first few happy numbers are 1, 7, 10, 13, 19, 23, 28, 31, 32, 44, 49, 68, 70, 79, 82, 86, 91, 94, 97, 100, … Interested in the details of this? Here’s more.
6. A 23-sided shape is called an Icosakaitrigon.
7. It takes around 23 seconds for blood to circulate the body on average (of course it varies by person and what you are doing).
8. The fear of the number 23 is called Duotriophobia.
9. Oh, and it’s a dynamite song by the band Blonde Redhead
Hope this helps you Claire!
