This is a public service announcement for the number 24. Although everyone knows that it is the number of hours in a day, the number 24 is much more interesting than just that. Posts labeled 'PSA' or 'Service Announcement' are here to symbolize all those silly things that you will never think about unless you take the time out of your day to think about them. Ain't that a contrived sentence?
Anyways continuing onwards. The number 24 is the basis of a young children's game to better arithmetic skills. Often played with 4 numbers you use various arithmetic sequences to yield 24. For example, (5+7) * (6/3) = 24. In music, there are 24 total scales, major and minor meaning. By that I mean that there are 12 major and 12 minor scales for a total of 24 scales. Disregard Dorian, Lydian and the like for that number.
Mathematically, the number 24 is extremely interesting. It is the first number that can be formed by the sums of 3 different pairs of prime numbers, 7 and 17, 5 and 19, and 11 and 13. It is also 4! = 1 * 2 * 3 * 4 = 24. To sum up the rest of these mathematical wonders I leave you with this. Sorry if this post wasn't as interesting as some of the others. But if you want to know some new things, Wikipedia is pretty awesome as long as you have a starting place. Hopefully something there helps you down the line, if not, take pride in learning more about a pretty intense number. I hope that even if you didn't enjoy the post, you'll at least take a look and learn a bit.
