It is the square of 30 and the sum of Euler's totient function for the first 54 integers.
Um, do you know what that really is? It is the reason why it took me two years to pass freshman algebra in high school. It is the reason I was the only senior in a high school geometry class full of freshmen (for only two weeks because I dropped the stupid class). It is the reason math is my Lex Luthor, my archenemy.
On a lighter note, the year 900 was when the Postclassic period began in Mesoamerica. It was the year that those tough Venetians managed to repel the pesky Magyar raiders. It was also the year that everyone's favorite Pope, Benedict IV, succeeded Pope John IX.
900 is also what this post represents. I have somehow managed to sustain this little blog thing for 900 posts now. What began as a place for me to overshare has in the last seven years evolved into, well, a place for me to still overshare. So not much has changed, has it? No need really to go back through and look at the highlights of the last 899 posts. That's why there's a 'search' box on the blog. Besides I go back and look at some of it and it reads like an entry into "Mortified Nation." Good times, people, good times.
As I have said in the past, I can't thank you enough, the Den loyalists, who have taken a seat on the sofa here in the Den. I'd like to think I'm doing something right because you're sticking around. I'm glad your my friends. Thank you.
Now, it's 100 posts to 1000. I've got things to think about because there are still stories to be told here.
