Prime numbers, myself and Madhava of Sangamagrama

There are ways to express numbers and number system.
One is Riemann zeta functions.
Second is #PythaShastri p(k) / p(k+1). This expresses the hope that there will be another prime.
Third is #PythaShastri p(k)-1,p(k),p(k)+1. This gives a hope of next number.
Madhava of Sangamagrama was of the third variety. Hope of next number.
If you subtract the first from third you get second. That is the small trick he played and got series of pi and theta in terms of tans.
He wrote in cryptic Sanskrit with words difficult to understand.
I did a even number jumps but then I got the original series .
Also I believe in explaining and getting acceptance.
Madhava of Sangamagrama caused much disgrace to himself by doing the theta and tan equations. He should have realised a trick is good only once. Shameful Madhava goes on and on for an angle can be equated to tan only for small angles.
He could never have got the sines and cosines functions without explaining e series. No wonder Kerala astronomy academy has been reduced to dust.
Euler was of course different from all of us and made genius methods.

Gummidipundi - A Short Story


Father Cristello was standing in Gummidipundi railway station to catch the electric train to reach Chennai. The platform was empty and there were only a few people.
A man sitting in a train in adjacent track was playing with a ball. He was throwing the ball up and catching it. The man glanced at Father Cristello and shouted, "Keep observing me father. Me, the ball and the train. Please father, do observe." He waved at Father Cristello.
Father kept observing the man, the ball and the train. He shouted back," A parabola, a stationary you and a stationary train."
Suddenly, the train in which the man was throwing and catching the ball, moved. The man shouted,"Now father ?"
Father shouted back, "A parabola of the ball."
The man shouted back, " To me the ball came back. Isn't it amazing ?"
Father replied back,"Yeah, relativity. "
The man waved back at Father Cristello and shouted, "Have a nice day !!"

Itarsi - A Short Story



Gautam Adhikari looked up at the window from his 2nd AC berth in which he was lying. The train had really slowed down and he was curious to know the station, though he knew it must be Itarsi.
He was a frequent traveler in this route. He worked in Nagpur and his family was in Delhi. He was leaving Nagpur after a grueling six months of work. He took a fortnight's leave to meet his family in Delhi.
He realized he needed water and got down to fill his bottle with water. The queue was unusually large and he stood in it waiting for his chance. Finally, he got his chance and was able to fill the bottle with water. He turned back to approach his train and could not spot it. It had left !!
He did not panic. As he was confident of the route. It will take another 3-4 hours for the next train and he cared the least for his baggage. He can always buy shirts and trousers, anyway, he thought.
He looked out of the railway wall and saw a few military personnel playing volleyball in shorts and vests. He was a good player of volleyball and he thought of joining them to pass his time for a couple of hours.
He approached them and said, "May I join you in this game? I missed my train to Delhi and the next train is a couple of hours later. I am good in this game."
One of them, a little weak as compared to others, said,"Sorry. No way can you play with us."
Gautam said,"Fine then. I shall leave. Anyway let me sit here and watch you play. I like this game a lot."
Gautam sat in a corner and watched the soldiers play.
He was observing them play and was enjoying the game. Then a ball hit by one soldier, reached near him bouncing. As it reached near him, the ground on which the ball hit made a metallic sound. Then
there was a beep from the pocket of Gautam. Immediately the weak soldier ran towards him and with a rapid motion slashed a big knife at Gautam and killed him.
Gautam was happy that he is killed. He managed to whisper, "Mera Bharat Mahaan !!".
(Gautam was a software engineer in Nagpur working on nuclear projects. The beep came from a radioactive detecting hardware kept in his pocket!!)

Asansol - A Short Story


The train stopped at Asansol.
Raghav Mukherjee looked out of the window and saw the water tank. An old man was taking a bath from the water oozing through a hole in the tank. He seemed to be optimistic and contended. 
Raghav then had a glance at a young boy sitting near the water tank. The boy must be about 11 years old, Raghav thought. He was well dressed and seemed to be from a good family. But he was weeping. He seemed to have lost all hope.
Raghav was himself in a hopeless situation. He could not understand his B.Sc Maths subjects and was failing miserably. His father would beat him everyday and he had run away from his home in Kolkata to a destination which did not matter.
Raghav then had a brainwave. He thought of getting down at Asansol and figure out and help the little boy sitting and weeping near the tank.
He got out of the train and crossed the railway tracks to approach the boy.
Raghav offered the boy a candy and sat close to him. He enquired where was he from. And where are his parents.
The boy said, "I live in  Gariahat in Kolkata.  We were travelling in a train, coming back from a marriage in Mughal Sarai. My father, mother and I. I and father got down here to fill water. The train started moving and my father ran and entered the train. I was left behind."
Raghav then asked when did this happen, his father leaving him here.
The boy replied, "Five days back".
Raghav could not believe it. His father may have deliberately left the boy here in Asansol, who knows.
Raghav then asked for the address of his house in Kolkata and prepared to take the boy back to his home.
They reached Kolkatta in a few hours. Raghav then took an auto to Gariahat and reached the home of the boy.
The father of the boy showed no emotion on seeing the boy. The boys mother seemed to be a little relieved. 
Raghav did not ask anything. The boy's father did not say anything.
Raghav just waved goodbye to the boy and left.
Raghav thought to himself how people could be. They all seemed small and hollow.
Raghav saw a broom lying ahead of him astray in the pavement. He picked up the broom and told himself "I shall forget my graduation. I shall start a new life. I shall become a sweeper."

Is America a great country ?

No, it isn't.
Then?
It is the greatest country in the world.
We are in the offices and getting the picture of the world through media and internet. Be it a government office, a R & D office or a private office.
But it takes a visit to America to know about it. I had been to USA and it is wonderful. Get the real picture.
