HeheHehe.
I really cant believe I am gonna blog on something rather technical. It feels good in a way to do that.
I had this amazingly fascinating lecture on something called "Brownian motion" today. And quite abnormally, I was totally glued (physically and mentally) to the lecture.
Y ?

This is one of those concepts which I would classify under the "beauty of mathematics". For readers who have no clue of what I am talking about, Brownian motion is the mathematical way of trying to explain the path that a particle of dust takes when it is randomly bombarded by sunlight , air molecules etc. Using Brownian motion we try to get a mathematical expression for the most random and irregular of happenings in life. Have any of those phenomenally less talented guys (like me) ever wondered what it would take to actually try to give an expression for anything and everything you see ??? I dont think many would have thought about it. But I always have. Just drawing a zigzag line and trying to think " Sheesh.. There is actually an equation to define even this curve and I have no idea what that is..", used to be a little depressing atleast because it reminded me of how little I knew. But today I had a glimpse of that.

There is more to math than mere (a + b ) ^ 2 = a^2 + b ^2 + 2ab .

However, on the examination front, my marks are characterized by a Random variable which has an increasing probability for taking lower integer values. How (much is the ) "mean" !!!!! :-)

Never even dreamt that I would blog on my opinion on Brownian motion when in Seventh Standard I heard this statement for the first time.
"The movement of very fine insoluble particles in water is characterized by Brownian motion."

Okay, as I conclude, is someone thinking why a Financial Engineering student is talking about Brownian Motion. It's actually a little weird. The movement of a dust particle in air and the movement of stock prices are characterized by the same equations ( with a set of rather misleading assumptions :-) .. )

As my professor mentioned, here is the link:

http://en.wikipedia.org/wiki/Louis_Bachelier

What fascinates me most about the Wiki entry ? :-)
... "Bachelier arrived in Paris in 1892 to study at the Sorbonne, where his grades were less than ideal."

Reallllly reallllly exciteddddddd :-)
