This blog post is a day too late. I just discovered that yesterday, 29 October, is Integral Day. Yes, that Integral we learn in school during Calculus.
The Integral Symbol was first introduced on 29 Oct 1675 by German German philosopher and mathematician Gottfried Leibniz. The symbol was based on the long s character, and was chosen because Leibniz thought of the integral as an infinite sum of infinitesimal summands.
Before we go on, I want to let you know that I hate Calculus (together with Integral, differentiation and everything Calculus). No, actually I don’t just hate Calculus. I hate Calculus to the power of infinity. In fact, if Facebook, Twitter and Blog exits during the days when I’m was in school studying Calculus, I bet they will be filled with vulgarities scolding all the mathematician that came up with all these theories. Sometimes I think they did it on purpose so that students all over the world will sweat and cry over their theories for centuries.
During my Secondary school days, one of my crazy ambition was to be a mathematician so that I can come up with a even more difficult math theory than Calculus and cause extreme hardship to students born after me. Luckily I didn’t do well in maths and the world we know now is a better place.
The last time I used Calculus was at the exam hall. After that, I never find myself in a situation where I ever need to use Calculus. I bet I’m not the only person. And honestly, I’m glad I never land myself in a situation where I need to use Calculus to save my life. I’ll most likely die before I complete writing the Integral symbol. Don’t get me wrong. I know Calculus is important. But I just hate it. Hate it, hate it, hate it, hate it, hate it, hate it, hate it, hate it, hate it……..
Anyway, enough of ranting. Happy belated Integral Day to all you maths lovers out there. To learn more about the history of Integral, check out this Wired article.
