To start the last week of March Mathness, because it’s a Monday, I’m going to go easy on y’all with some light, easy topics. (Maybe I can lull you into paying attention for the major topic of the month: matrix rotation.)
It has occurred to me that, if I’m talking about math in March, I absolutely must mention one of my all-time favorite mathematical objects, the Mandelbrot. I’ll try to get to that today, but the main topic is a simple something that I ran into while working on my 3D model of the big island of Hawaii.
The question was: How many miles are there per degree of latitude?
It’s one of those days you remember better than any birthday or wedding. Those were planned; these hit you suddenly, stunning your mind, breaking your heart. “The shuttle blew up!” “The Towers fell!”
The impact was even greater if you saw it happen in real-time. If you watched the shuttle launches. If you caught the breaking news before the second tower was hit. Saw the second plane, realized at that moment, “This is no accident!”
Even if you saw it after, you saw it; saw it as an attack.
This one’s mine!
So I was conversing with a fellow I know, and the right side of my brain asked the left side, “So just how much square footage per person is there these days?” We both agreed that seemed like an interesting question (given all the people running around these days), so we looked around for a body to help us research the answer.
We just happened to find one handy, so off we all went to the virtual library and math lab. Unfortunately our math consultant was a Communications Arts major and made a small error thinking square kilometers to square miles was the same as kilometers to miles. Fortunately everyone involved obsessively double-checks their work, so we caught the error in time.
Pity, though. The original answer would have been fun to write about.
Those who know me know that I’m not big on calendar holidays. Even my birthday tends to pass without fanfare. That comes from being single, the island that supposedly no one is. After a lifetime of Christmas and New Years’ being ordinary days, you get used to it.
But I do honor the Solar Event Days because (as I’ve mentioned many times) light is so important to me (and because I’m a geek). Christmas may not mean much to me, but the Winter Solstice does! The days finally start getting longer! Summer Solstice is a day of mourning for the opposite reason.
Today — the Autumnal Equinox — marks the halfway point.
