Dear Friends and Students
Today I received a thought provoking LinkedIn Message from Yeseswini, one of our Alumni (CSE 2013-17 batch), currently working with TCS. Look at the above picture.
My Question to you. What is the shortest path between New York and Moscow in the above picture? Is it straight-line or curved path?
Our basic common-sense tells straight-line right? Even, our mathematics teachers teach us the same right. As per the Euclidean geometry, the shortest distance between any two points is always a straight line.
But, surprisingly It is wrong in this special case!! The shortest distance between New York to Moscow is NOT Straight-line but CURVED LINE as showed in the above picture.
Euclidean geometry shortest distance theory (straight-line) works only for flat surface (2D)! But remember, EARTH is NOT Flat! This is explained by Riemannian geometry.
Flights takes these curvatures rather straight-line to reach destination in a shortest distance!
Why this post is intriguing me because couple of weeks back I was working an ambitious thought and devising plans to implement that in future. Few incidents took place in between and made me to drop the project.
I see parallel between these two. We plan something but plan get changed totally without our intervention.
However, there is a grace point here. Riemannian geometry teaches us the philosophy as well. Who knows our plan might be the perceived shortest distance (straight-line showed in the above picture, actually long but perceived short by naked eye) and God’s plan might be the curved distance (curvature showed in the above picture, actually short but perceived longer by naked eye).
Lot of people give positive quotes and motivational lectures. They may help us to get inspired in life. However, if there is no cooperation from GOD, your plans have no significance and never reach destination. This is THE fact. However, we need to move on, continue with our efforts!
EARTH is NOT FLAT, so as Perceived Short Distance is NOT Real Short Distance
Your Well-wisher
