Inertia has been known for a long time, by Chinese and Islamic scientists. Sir Isaac Newton defined it as:
"The vis insita, or innate force of matter is a power of resisting, by which every body, as much as in it lies, endeavors to preserve in its present state, whether it be of rest, or of moving uniformly forward in a straight line."
So when I kick a ball it will move and it will continue moving until it hit a wall or some rock changes its direction or eventually stop by the power of fraction.
Doesn't this really apply on our lives? I already wrote an article about this that you can read it here.
I just finished writing my 10 pages CV when my friend comes with the cup of Coffee as he say "What you are doiiiiiiiinnnng?" rubbering his nick and tripped and pour the whole Coffee on my Laptop. I just lost the laptop and all my work.
Hence its so obvious that I will be angry. I will remain angry for a certain amount of time until someone tries to calm me down or I get my laptop repaired or I forget. Inertia is there.
You go to watch a movie full of action and art of fighting and just about all tech-stuff you love, when the movie finishes. Your brain keep spinning and spinning around that part of the fight for a certain amount of time before it disappear.. This is Inertia.
Some organization conducted a study. They took 50 people divide them into two halves. They gave the first 25 people a mathematical problem and made the second 25 to listen to a romantic song.
When they finished they gave them a donation letter. The same letter for all 50 people. "Please donate to Rokia a 17 years old poor girl from Mali..."
The first 25 people (With Mathematical problem) donated much less than the second group.
The people who solved the mathematical problem used their left brain for analysis .. And they maintained an inertia so when they received the letter they didn't think emotionally... Unlike the second group who used their right brain..
Inertia is Everywhere..
