Python Software Foundation - SfePy : GSoC 2013 : Week 2



Hi Pythonistas,

After developing more understanding of SfePy I moved towards implementation.
The first phase of my project involved implementation of convective-diffusive equations.

So with the help of my mentor R (Robert. He is awesome!), energy equations were implemented.

The sample problem taken was:

r"""
Steady Axial convection and diffusion in slug flow with velocity :math:`U _0`
in an insulated pipe.
It is subjected to specified temperature at the entry and exit lengths -
:math:`T _0 for x \leqslant 0`
:math:`T _1 for x \geqslant L`
:math:`\alpha \frac {\partial T}{\partial n} = 0 on the lateral surface of the pipe`
Find :math:`T` such that:
.. math::
        \int_{\Omega} c \nabla v \cdot \nabla T =
        - \int_{\Omega_L} (\vec{u} \cdot \nabla T) v
"""

Now the results were pretty interesting :




The results were in accordance with the Peclet number graph which predicts the Temperature distribution in a convective-diffusive case. 

We have realised that a robust Navier-Stokes solver is necessary for the project compared to the present solver so our next task is to get that in place and then move ahead with the coupling of the two equations.

Cheers!

Up Next: Navier-Strokes Eq. Solver

Python Software Foundation - SfePy : GSoC 2013 : Week 1



Hello Pythonistas,

I am Ankit and this week I kickstarted my GSoC 2013 Project - Enhancing the solver to simulate solid-liquid phase change phenomenon in convective-diffusive situations. I am a dual-degree undergrad pursuing my masters in phase-change material simulation.


Previously I had worked on the post processor of Abaqus, a commercial software, in my internship and always dreamed of working on a solver. Surely it was an honour when I was given a chance to work on SfePy as my GSoC project.

This project is pursued under :



"Briefly, SfePy is a software for solving systems of coupled partial differential equations (PDEs) by the finite element method in 2D and 3D. It can be viewed both as black-box PDE solver, and as a Python package which can be used for building custom applications. The word 'simple' means that complex FEM problems can be coded very easily and rapidly."

This week ended with:
  • Finalizing the weak form of the equations to be implemented.
  • Tinkering with the examples and code-base to know the entire architecture which is very modular and powerful.
I realised that lots of challenges are awaiting ahead, but the interesting part is that SfePy falls under the umbrella organisation - Python Software Foundation 

And you know I Love Python!

So the adventure has already begun ...

2779 AD: Extinction

Adam Elevator Space Base | 62,137 miles above sea level | 2779 AD



Bruce sighed while waiting at the cargo bay for the elevator's arrival. He had been following the same schedule for last 10 years – collecting the cargo sent by his associates on Earth which usually included new test equipments and some belongings sent by his family and friends living below. A taut carbon nanotube composite ribbon was anchored to the platform. It continued a few thousand miles above into the space and finally hooked into a trapped asteroid which acted as a counterweight. He could sense the dampened vibrations of the approaching elevator. He was feeling a bit upset today as on this fateful day, five years back, his dear friend Luke had vanished mysteriously.

Tycho Crater | 100 miles from SpaceX Colony, Moon | 2774 AD

Luke drove his rover through the Lunar highlands covered with regolith, a mixture of fine dust and rocky debris, and reached the source of the strange signal he detected today. He slid down the gentle slope of the crater and started leaping towards its centre. After walking a few miles the dusty terrain started turning smooth and shiny like an ice-floor. He inserted his probe and started examining the floor closely. It turned out to be a super-cooled liquid glass.
“What is this glass lake doing in this crater?” He wondered.
He turned his head upwards and gazed at his home planet. It was looking serene and beautiful.
Suddenly a thought clicked in his mind.
He took his receiver and plugged it into his suit. He told Lina, the computer built into his spacesuit, to analyse the signal with respect to Vasin-Shcherbakov Equations.
After a few seconds.
“Luke. This signal encodes the current satellite image of Earth with an extraordinary resolution of one mile on Earth to one mile on the data transmitted.”
Luke was shocked- “How on Earth is this possible! This crater contains the most gigantic telescope, constantly keeping an eye on us and we never knew. How did we miss it? I must head to the colony and tell Bruce about this.”
As Luke started drifting swiftly towards the rover, he felt a strange presence, as if he was not alone. A dusty breeze blew through his airtight suit. He was shocked at the thought of something penetrating his suit.
The next moment his power-suit turned off.
He tripped.
Turned his head.
Saw a faint silver figure floating in air and never woke up.
The giant lunar telescope was not the first alien technology mankind ever came across. Something similar happened 800 years ago.

Groom Lake | Southern Nevada, U.S. | 1949 AD 


The lake was shrinking season after season. Old Timothy Adams was having a dip in the lake when suddenly he felt something big under his feet. He informed the sheriff and soon they pulled out that saucer shaped object. Rumours of this strange object spread and this area was cordoned off quickly. They named it Area 51, a secretive military air force base.
After a few years, disruptive technologies started pouring out in US- Fibre optics, LASERs, Kevlar, Titanium fighter planes, Transistors (the birth of computers)– and some of these totally changed our world. Some technologies took centuries to reverse engineer, like the hydroxyGEN– which could split water vapour in air and provide us both Hydrogen fuel and pure Oxygen.
It still remains a well kept secret that the technologies we boast off today, had their origin in that one saucer which landed on Earth maybe centuries ago.

SpaceX Moon Colony | Maria Levita, Moon | 2779 AD


It was a peaceful lunar settlement, flocked with twenty families as a part of the SpaceX lunar experiment. The colony was a closed ecological system where all nutrients were recycled. It was self-sustainable requiring no Earthly support.
Bruce entered his house. Sam was eagerly waiting for his dad. He was wearing a strange skimpy suit covering his entire body except his head.
“Hey son, look what grandpa sent you.”
It was a slimy fish with orange scales. Swimming to and fro in the container. It looked beautiful.
“Dad, it belongs to which species?”
“I have no clue Sam. Try asking Ela.”
Sam moved his hand and positioned his palm facing the fish.
“Ela, tell me all details you find on this fish.”- He said it on his microphone.
Green rays came out of his palm and started scanning the fish. The rays stopped and Ela, his personal supercomputer, soon arrived at an answer.
“It is an Oranghy also known as the "slimehead". It is slimy and has orange scales, having a typical life expectancy of 150 years. It is found along the North Atlantic coast. It became extinct 50 years back due to overfishing.”
Sam looked at this cute fish and started feeling sorry. Man's inherent nature to dominate the entire planet never changed. As centuries passed, species extinction had continued at an alarming rate due to human activities.

Amazon Desert | Brazil | 2779 AD

What was once 2.1 million sq miles rainforest was now reduced to a desert with just a small patch of land covered with trees. Millions of species residing in those forest were now extinct. An automatic lumberjack came and started logging the final patch.
The moment the last tree touched ground, 2000 orbs left the Gioni Crater on Mars.

Adam Elevator Earth Base | On a Pacific Isle | 2779 AD


“Stephan, today around two thousand silver orbs destroyed all major cities around the globe. A high energy plasma beam emitted from a single orb wiped out an entire city, leaving behind just a rocky terrain. With all major government centers gone, the entire planet and its people are thrown into chaos."- Andy told me.

A day later, everyone, including me, enlisted in the army, in order to protect the Adam Earth Base as that was our last resort to escape this doomsday. It was our last hope.
We took our positions and surrounded the base.

Five hours later, three elevated figures appeared far away. The humanoids looked identical, shaped like an ideal human. We started shooting at them with our laser guns. It was a futile effort.
Their silver suits were made up of technology never seen before-
Nanotech? Biotech?
No.
It was nowhere near as simple as that. Its material was inserted with an integral DNA of living organisms. Customized artificial neurons were working in conjunction with their nervous system. Those metallic suits responded to their thoughts. It was an amalgam of biotechnology and mechatronics. They were controlling it perfectly. Our laser beams were easily blocked by their techno-organic armour which altered itself automatically to create a shield in order to obstruct the trajectory.
They were close. We were scared.
None of my shots were even close. I was just another scientist holding a gun and wearing a power-pack, stupefied by their alien technology. One of them was now floating in air facing me. I shot at him insanely, to no result. He extended his hand fully towards me, keeping his arms straight and locked. His palm a few feet away facing my head. Suddenly he turned and shot a spherical ball towards Andy. The ball appeared out of nowhere on his palm. As if lots of molecules on his palm assembled to form that sphere. As it reached Andy, the sphere disintegrated into the air. Andy's power-pack failed and then a few moments later Andy dropped dead.
I could predict that this superior race had already harnessed Technovores- Synthetic alloys and unknown biological entities that invade the system compromising power source and life out of the cells of the host. The silver Technovore shield was made entirely of nanobots. It had the ability to disassemble itself into a stream of nanites which carries a copy of the entire viral personality, and implying that the whole entity can reconstruct itself from a single unit. It absorbed technology into itself, adding the abilities of consumed technology into its physical being. It was a bio-tech warfare, probably the first and the last mankind would ever see.
The alien turned his head and looked directly into my cold eyes.

SpaceX Moon Colony | Maria Levita, Moon | 2779 AD

Bruce and Sam started running towards the escape pods kept at the edge of the colony. But when they reached it was already too late. The five pods were already carrying eight families. Bruce was holding Sam's hand standing in despair. They could see the SilverMen on the other side of the colony shield.
The pods launched.
SilverMen positioned their palms shooting hundreds of globules into space which disintegrated on contact with the surface of the pods. Three hundred feet above the ground those pods annihilated.
Sam could not bear the sight. He hugged his dad and started crying. Right now he felt just like the Oranghy – alone, entrapped and helpless.
“Dad, are we going to become extinct?”

Book Review: Shoes of the Dead




Journalist Kota Neelima has delivered a powerful political novel in the form of 'Shoes of the Dead'. It is a chilling parable of modern day India, featuring characters that readers don't encounter too often - greedy money lenders, farmers burdened by debt, unscrupulous middle men, corrupt doctors and district collectors struggling to work. Also we encounter the big city journalists, the well heeled academics and the smooth-talking politicians.

The story begins with the death of Sudhakar Bhadra who kills himself over-burdened by debt due to successive crop failures. The powerful district suicide comittee of Mityala routinely dismisses the suicide and refuses compensation to his widow. Gangiri Bhadra, his well educated brother, makes it his life's mission to bring justice to the dead by influencing the committee to validate similar farmer suicides. His own personal life is full of crisis where he is barely able to feed Padma, his brother's widow, and her two children two square meals a day. Fully determined he comes up with a plan and soon commitee members turn to vote for suicide due to debt. While he treads on this path, the readers come across some harsh realities of rural India like poor healthcare. Dr. Hemant Rao who has his own dark side where he cheats the hospital by stealing medicines and faking innovices in order to treat the poor farmers for free.

Keyur Kashinath of the Democratic Party is the MP from Mityala and son of Vaishnav Kashinath, a veteran politician. He never visits his constituency and inherits his father's power in Delhi politics. He believes that owing to his lineage it is his divine right to rule and forgets the people's right to rule. He faces his first crisis when every suicide in his constituency certified by the committee as debt-related turns out to be a blot on the party's image and his competence. Meanwhile Nazar Prabhakar, a journalist, comes up with his article "Mityala MP should quit if farmer suicides continue: Demand Voters, seek relief measures" which forces Keyur to visit his constituency.

The brilliant farmer battles his inheritance of dispair, the arrogant politician fights to keep his inheritance of power. The two worlds collide in a conflict that pushes both to the limits of morality, from where there is no turning back. And in the end, there can be only one winner.

This well researched novel surely gives readers a deeper understanding of the complexities at the heart of this nation and brings up the issue very well.
A must read!

3047 AD : Troy



3032 AD
"Whoa! Robert we did it, it’s amazing we made a profound discovery in our solar system. It truly does give a deep insight into science," said Kurt the administrator of Space-X.
Robert was the deputy administrator of this private firm which had advanced miles ahead in the field of space research compared to NASA and other government organisations. Just a few hundred years Space-X had made Mars habitable for Human settlement by inducing climatic conditions similar to that of Earth. 
"Yes we did it. It’s a combined effort of our team, without them we never would have found that wormhole." said Robert.
"Yes, and to think that there would be a wormhole between the planet Mars and the asteroid belt is truly astounding" said Kurt.
"Kurt you know how eager I am to discover new colonies of life outside earth and get to know their culture and existence and I truly believe this opportunity could be used to the fullest and explore the unexplored. We are lucky that this is a traversable wormhole and space travel could be done through it." Robert asked Kurt with extreme delight in his eyes.
"A wonderful opportunity indeed." Kurt replied. "Considering that and the fact that it is impossible for life travel to take place through that wormhole we must make a satellite which could send radio waves through the worm hole."

3035 AD
"Pandora 619 is is ready for the launch Robert," Kurt said cheerfully.
"Let's begin the countdown."

3045 AD
"Kurt, there is a serious problem at hand, the connection with Pandora 619 is cut and cannot be re-established."
"It’s alright, we covered most of the part of planet Redik through Pandora 619, we will find an alternate solution and even inform the situation to the Garganians who have their planet Gargan near the satellite. Maybe they could help us as they have been helping us by lending their technological marvels over the past few years since we made our first contact." said Kurt filled with hope.

3047 AD
"Kurt, sorry to disturb you at this moment but our watch-station 4 has just sent an emergency message, it says that an unidentified object is heading towards Earth. I’ve even contacted Gargans, but they denied it being theirs. It is approximately 5 days away from earth." said Robert confused.
"All right I will look into the matter." Kurt said calmly.

The following day Kurt seemed to be rejoicing.
"Cheers! I am very happy that Pandora 619 is returned. We could possibly use it to test Redik's soil samples. I even asked the watch-station to conduct an X-ray scan of Pandora 619 but it seems there is no danger."


That night Kurt returned back to his home overlooking the Martian Delta. Suri, his daughter, was eagerly waiting for her dad.
"Dad, look what I found while I was browsing the SMAI today. On Earth there was a lost city of Atlantis which was discovered 500 years ago. It was created by the survivors of Troy who wanted to live at peace after its destruction because of the Trojan Horse." Suri paused. "Dad what is a Trojan Horse?"


"My girl, the Trojan Horse was a way of deception used by the Greeks who wanted to win against Troy in a war. The Greeks hid in the wooden horse and the army of Troy thought of it to be the gift of victory and took it inside. When inside at night the Greeks crept out and called in reinforcements and slaughtered the army of Troy. This was the Trojan Horse," said Kurt thoughtfully.

"Dad, this is cheating." Suri was sad.
Kurt then began to contemplate.
He then stomped his foot and quickly headed towards the Space-X office and called Carter the man in-charge at watch-station 4.
"Carter, its me Kurt, sorry to disturb you at this time of the night, but could you tell me how far is Pandora 619?"
"3 days sir," replied Carter.
"Could you please take an electron beam scan of Pandora 619?"
"Right away sir."

The next day Kurt was holding the reports. He was puzzled.
Holding the reports in his hand Kurt called the Extra Terrestrial Space Force Captain Norman Scruze.
"Norman I want Pandora 619 to be exterminated immediately. And please make sure it is done as soon as possible" Kurt said.
"Sure sir" Norman replied.
After 13 hours the the whole sky is blinded by a white light.
Kurt arrived to the unit and smiled at his staff. Everyone including Robert were stupefied by this phenomenon.
"I am glad the report saved us Kurt." - Robert remarked.
"It didn't, Robert. The reports were negative. The Garganians sent back the satellite Pandora 619 with loads of anti-matter which if it would have made contact with any planet would have lead to total annihilation. These reports provide us the proof that our technology is still far inferior. We need to figure out their future plans. They are nothing less than demi-gods who are gearing up for a war. This was just their Trojan Horse."

Adobe Creative lock-in. Is it high time we reboot our software practices?



It's May 6, the third day of Adobe MAX conference, Los Angeles quoted as "The Creativity Conference". Creative Enthusiasts from all around the globe had their eyes on the launch of CS7. But Adobe closed the door on the Creative Suite and introduced Creative Cloud. The acquisition of Behance in December 2012, for  which Adobe paid more than $150 million in cash and stock, should have been served as a hint that Adobe was aiming for a social and collaborative future in the cloud. Adobe even said it will no longer be developing its Creative Suite range of software, leaving its subscription and cloud-based Creative Cloud as the only way of accessing the latest version of Photoshop. Adobe has been trying to encourage users away from the traditional one-off payment licenses and on to a "monthly payment model", with features such as online storage and syncing between devices. This latest move ups the ante by making it the only option for future versions of the software. As of the first quarter the subscription of the new cloud service has already exceeded 500,000.[1]

Does this move makes sense?

This move is surely to curb piracy as almost 50% people use the pirated version of this software. But the real people who are going to lose are the hobbyists as it will undoubtedly be unsettling for many people who have always thought of software as a one-off purchase. The serious amateur photographer who buys a version of Photoshop and then use it for 5-6 years or the girl who uses only Photoshop. Now they’ll have to pony up and pay the $30-$50/month for the single app. Personally I don’t like the idea of software as a service. There’s something unsettling about it. I like buying a piece of software and knowing that I can install it and use it for years without paying the company another cent. It’s ‘mine’ even though I know it’s only a license.




But somehow it is our own fault as we never looked into the open-source alternatives at the first place itself before downloading the torrent file + crack. Ten years back when Photoshop was not that powerful, we - creatives, clung to it which eventually led to a creative lock-in, where we are dependent on this product to such an extent that open-source software such as GIMP also has a version of Photoshop look alike- GIMPshop. It is high time we seriously consider using open-source alternatives like Xara(for Corel) and Blender(for Maya, Cinema4D, 3DS max) which are equally powerful. Although it will have some learning curve but at least think about the long term benefits over the short term gains. Become a developer and even contribute to these open source projects. Only then we will be able to avoid such creative lock-ins in future.

The Flip Side #1 : Mi Nathuram Godse Boltoy

It’s natural to be influenced when we hear or read something — especially if it’s well presented, but it’s important to remember that you may not have the whole story. There are always  two sides to every story, and it benefits us to make sure we know and understand both sides before making a judgment or rendering an opinion. The Flip Side is an attempt to present you the less familiar aspect of some stories.

The Flip Side #1 : Mi Nathuram Godse Boltoy

Pradeep Dalvi's controversial play which ruffled feathers in 1989, when the playwright was denied permission by the Maharashtra government to stage the drama. After its brief resurrection nine years later, the state government banned the play. Read the play and judge for yourself if the ban was justified.

(The stage is dark save for one spotlight, which is focused on Nathuram, who is standing with his back to the audience. Suddenly he turns and starts looking at the faces in the audience, as if he is searching for someone. Ultimately, he jerks his neck indicating denial or negation and looks up. Now he is directly looking at the audience.)
Nathuram: No. All the faces are unknown. Actually 'unknown' is the wrong word to use in this ... All your faces are very fresh to me...fresh and new. They are, of course, new to me, but mind you, they are not unfamiliar.
The youngsters among you, were not even born at that time. You must have read about me as a Hindu fanatic in the history written by the government. The middle-aged amongst you must be very confused clinging to their parents, who in turn were running around to save themselves from the massacre of Brahmins as the outcome of the assassination -- asking: 'Who is the Nathuram? Why are our houses being burnt because of him?"
But the elders among you... You must remember me! You must have heard about me on the radio. Some of you might have read Agrani, the newspaper run by myself and Nana Apte. Some of you might have attended my meetings and heard my speeches. Some of you may be knowing me directly or might have met me, but must be refusing the acquaintance after January 30, 1948.
Do you know how old I am? eighty-eight, nearly 90! Do you think I am lying, because I look young? Do you know, the mystery behind my youth is my death. My death...it was untimely, but it was heartily accepted!
I was born at the beginning of this century on May 19, 1910. My father Vinayakrao was in the postal service, my mother's name was Laxmi.
Vinayakrao was drawing a salary of Rs 15 per month. He used to spend Rs 10 on his family and send Rs 5 to his parents. Vinayakrao and his wife had three sons, none of them survived. They prayed to God, had their fourth son, Nathuram. Nathuram survived because they were destined to suffer for their young son's death and Gandhi was destined to be assassinated.
The rest of my life was very smooth.
I never stole in my childhood, so there was no question of apologising to my father. I never took a vow of celibacy as I was already practising celibacy. I was moving around the refugee camps and helping the destitute with food and clothes. But I did not wander half-naked because the refugees were naked. I never spun yarn, never cleaned my toilet, never observed silence till I was hanged. There was only one common factor in Gandhi's life and mine. We were both the cause of each other's death. He wanted to live for his principles and I was prepared to die for my principles.
But the interesting part of the biography of Nathuram Godse starts on January 30, 1948. After the assassination of Gandhi.
In a sense, I lived only for 655 days -- from January 30, 1948 to November 15, 1949. But January 30 was an outcome of January 13.
The central government had taken a decision -- Pakistan will not be given Rs 55 crores. On January 13 Gandhi started a fast unto death that Pakistan must be given the money. On January 13, the central government changed its earlier decision and announced that Pakistan would be given the amount. On January 13, I decided to assassinate Gandhi.


January 13, 1948
(The editorial room of Agrani. There is the normal chaos that exists in the editorial room of any newspaper. Nana Apte enters.)

Nana: Pandit, where are you? Visu...
Visu: (Enters) Sir.
Nana: Have you composed and assembled the first page? Break the compose. This is a stop press news.
Visu: You want me to recompose the first page? There will not be any issue tomorrow.
Nana: Listen, we just have to reassemble the first page. This is a very important news. It was on the radio.
Visu: But Panditsaab is rewriting the editorial. I have to recompose and print that matter. How can we...
Nana: Where is Pandit?
Visu: He is sitting in the composing section. He is completing the pages and giving them for composing.
Nana: Call him.
Nathuram: Call? Whom?
Nana: I wanted to call you. We have to prepare the front page again.
Nathuram: No need. My new editorial is on the same subject. Visu just get us coffee. (Visu goes)
Nana: Do you know the news I am talking about?
Nathuram: Yes, of course. The Cabinet has changed its decision. It is giving Rs 55 crore to Pakistan. Gandhi has broken his fast.
Nana: You changed your editorial?
Nathuram: Yes. I thought that my previous editorial was nothing but a pack of lies.
Nana: Pack of lies? And written by you? Impossible!
Nathuram: Yes. Tomorrow is January 14, Makar Sankranti. I had written in the editorial, 'Don't celebrate Sankranti tomorrow, don't take sweets, don't behave in a sweet manner. Distribute rifles, bullets, weapons. Don't talk sweet, talk of war. Kill the enemies.''
Nana: It is true, what you had written.
Nathuram: You have not asked me about the title of my new editorial.
Nana: What is that?
Nathuram: Mere talk without actions is futile.
Nana: Meaning...?
Nathuram: It is time for protests in constitutional ways, processions, pickets to come to an end when the establishment resorts to mindless injustices. You can't just warn the government through editorials at such hours. Tell me Nana. What do you mean by people will not tolerate, people will revolt...and so on? Who are these people? Do you mean our readers or those who attend our meetings and listen to our speeches? No, Nana, people also mean you and me, us. If we forget what we write and what we talk then our editorials and brave speeches in the meetings and futile. A man addressing from the dais is also a part of the crowd sitting before him. When we say that the people should revolt, it means that we should revolt!
Nana: You have written all this?
Nathuram: Yes, I have written celebrate Dassera tomorrow, the festival on which war is proclaimed.
Nana: Pandit, we will be arrested.
Nathuram: I don't think, our Agrani is the mouthpiece of Hindu religion. When the government does not give importance to Hinduism, the question of being a mouthpiece does not arise. Our restraint is misinterpreted. Our massacre is neglected. They presume that we will bear everything with folded hands. Our anger has lost its fuel to burn, we know only the art of pardoning. They will torture us and massacre us and we will bear it coolly... it has become a law of nature. I don't think they will take cognisance of this mouthpiece of Hinduism. Yes, the government will think seriously while arguing the case in the court.
Nana: Which case?
Nathuram: IPC 302, the assassination of Gandhi.
Nana: Pandit, what are you talking?
Nathuram: Of course Nana, while writing the editorial, I was constantly telling myself -- these are not mere thoughts, they are a prelude to an action!
Nana: I have utmost confidence that Nathuram can never make a mistake, he is always right. But I want to ask you something because a blind follower cannot be a genuine friend...
Nathuram: Gandhi must be stopped at any cost.
Nana: I do agree with you.
Nathuram: And there is only one remedy to stop him. His assassination.
Nana: But don't you think it's a hasty decision?
Nathuram: You are wrong Nana. Assassination is never as easy as picking up a rifle and pulling the trigger, assassination is never an accident. Yes, murder could be an accident but not assassination. In this case of Gandhi, it could never be...
Nana: Are you convinced that it is inevitable?
Nathuram: Of course, it is not only inevitable, but is a delayed action.
Nana: Don't you feel that we would be tampering with an important era of history?
Nathuram: I differ with the word era. It could be a page, a leaf of history. Certainly not an era. Nana, if we don't turn this page today, the rest of the pages of the history of our nation will remain unwritten, blank...
Nana: Listen, Pandit...
Nathuram: Time is eternal, indestructible. You can turn its pages but never, never tear them out. Gandhi has acquired some position in history which nobody can deny, not even Nathuram. The page will be there forever in fact. Sometime in the future, in some storm, the pages will flutter and there will be that same Gandhi's page before the world. I don't refute Gandhi's theory of non-violence. He may be a saint but he is not a politician. His theory of non-violence denies self-defence and self-interest. The non-violence that defines the fight for survival as violence is a theory not of non-violence but of self-destruction.
Nana: I do agree with you Pandit, but don't you think that your decision is risky, dangerous?
Nathuram: But somebody has to do it! You can't afford to wait for somebody else to do it. It will be improper.
Nana: If we picket severely?
Nathuram: We have been doing it. Did it help? The division of the nation was an unnecessary decision. What was the percentage of the Muslim population as compared to the population of the nation? There was no need for a separate nation. Had it been a just demand, Maulana Azad would not have stayed back in India. But because Jinnah insisted and because Gandhi took his side, India was divided, in spite of opposition from the nation, the Cabinet. An individual is never greater than a nation, Nana. But Gandhi has stared considering himself greater than the nation.
Nana: Jinnah wanted to be the prime minister...
Nathuram: But we never opposed a Muslim prime minister. In a democracy you cannot put forward your demands at knife-point. Jinnah did it and Gandhi stabbed the nation with the same knife. He dissected the land and gave a piece to Pakistan. We did picket that time but in vain. The Father of our Nation went to perform his paternal duties for Pakistan.
Nana: The Cabinet consented to that...
Nathuram: The Cabinet also consented to the demand of Rs 55 crores today...
Nana: They are also equally responsible.
Nathuram: Of course, they are responsible! Gandhi blackmailed them with his fast unto death. His body, his threats to die are causing the destruction -- geographical as well as economical -- of the nation. Today, Muslims have taken a part of the nation, tomorrow Sikhs may ask for Punjab. The religions are again dividend into castes, they will demand sub-divisions of the divisions. What remains of the concept of one nation, national integration? Why did we fight the British in unison for independence? Why not separately? Bhagat Singh did not ask only for an independent Punjab or Subhash Chandra Bose for an independent Bengal?
Nana: Pandit, if you will write this, people will get agitated, the government will get agitated, the government will have to bow down.
Nathuram: I had written this before. At the time of Partition, when Suharawady surrendered only due to political pressure, but only Suharawady, not his followers...they went on with the massacre. Gandhi started his fast, the Hindus put their weapons down. I still remember that day. A poor Hindu told Gandhi, 'I am putting down my weapons because I don't want your death on my conscience but I am staying alone with my family in the Muslim area. That night, before leaving Hyderabad I visited his home. The whole household was screaming, weeping, his only eight-year-old son had been killed by the Muslims. He had no weapon to defend himself. He threw his son's body on my lap and said, "Take his blood to your Mahatma. Tell him, if he goes on fast again, he can finish it by drinking not orange-juice but my son's blood." I could not say anything. Gandhi was the Father of my Nation. For a moment, I was tempted to pull out the Muslims from their homes and chop them down. But I controlled myself. Violence for self-defence is justified, otherwise it is an ill-cultured act. I returned to where Gandhi was staying but he had already left by car. Of course, there would have been no point in meeting him... he would only have prayed for both the killer and the victim.
Nana: Pandit, I sincerely feel that we should seek the advice of Tatyarao.
Nathuram: No. Because I am going to assassinate Gandhi even if Tatyarao tells me not to. Then why involve him unnecessarily? I, neither want Tatyarao's involvement nor participation. He has suffered a lot for the nation. Now it is our turn. Tatyarao had once sad, if Gandhi is a political saint, then he should follow in the footsteps of Ramdas Swami. Ramdas Swami was always there to advise Shivaji whenever the need arose, but he never interfered.
Nana: Pandit, if you are firm, then I promise you...
Nathuram: I want two promises ...
Nana: I promise!
Nathuram: You didn't ask me what promises?
Nana: A shadow has not to ask the body as to where it is going and why it is going? A shadow has just to be with the body, that's all. When I walk, you become my shadow Pandit, now you are walking... I will be your shadow.
Nathuram: This is the first promise I want from you... This time I walk alone...mind you, alone...
Nana: You have trapped me.
Nathuram: But you promised me..! I am going to assassinate him in the open, before the public, because I am going to do it as my duty. If I do it surreptitiously, it becomes a crime in my own eyes. I will not try to escape, I will surrender and naturally I will be hanged.
Nana: Pandit!
Nathuram: One assassination, one hanging. I don't want two executions for one assassination and I don't want your involvement, participation or company.
Nana: Pandit, you want to end our friendship of so many years?
Nathuram: Of course not. At the time of hanging. I will remember my motherland, my parents and my friend -- you, Nana...
Nana: But if I won't be with you, won't you feel lonely at the gallows?
Nathuram: You promised me.
Nana: What is the second promise?
Nathuram: Today I wrote two editorials. I have not put any date on the second editorial as only God knows the date. I want you to print the second editorial in Agrani, the day after Gandhi's assassination.
Nana: I promise you my friend. The first promise accidentally but the second promise out of necessity. (Nathuram is alone on the stage)
Nathuram: I was convinced that though Gandhi is called the Father of the Nation, he delivers his paternal duties not towards India but towards Pakistan. I came to the decision that as a son of the soil, it was my first, foremost and divine duty to assassinate Gandhi.
On January 30, I reached Birla Bhavan at 12 pm. Gandhi was sitting outside on a cot enjoying the sunshine. Vallabhbhai Patel's granddaughter was sitting at his feet. I had the revolver with me. I could have assassinated him easily then, but I was convinced that his assassination was to be a punishment and a sentence against him, and I would execute him. I wanted witnesses for the execution but there were none. I did not want to escape after the execution as there was not an iota of guilt in my mind. I wanted to surrender, but surrender to whom? There was a good crowd to collect for the evening prayers. I decided on the evening of January 30 as the date for Gandhi's execution.


January 30, 5.00 PM
(Birla Bhavan. DCP Arjundas and a servant appear on the stage.)

Servant: No. Bapuji cannot spare any time now. He will be late for his evening prayers.
Arjun: I know. But I have come because the work is important. In fact it is to do with Bapuji's prayers.
Gandhi: (Enters) Who is it, Mahadevbhai?
Servant: Somebody to see you. I told him, you are getting late.
Gandhi: Who are you?
Arjun: (Salutes) I am DCP Arjundas, Bapuji...
Gandhi: We have met before... Wait a minute, don't tell me ... let me recollect. Yes, when Jawahar had come to Hyderabad, you were with him.
Arjun: (Smiles) Your memory is fantastic. You were very weak at that time.
Gandhi: It is the body that becomes weak. But fasting sharpens of the mind. Why have you come today? For prayers?
Arjun: Yes. I want to request you to let me accompany you for the prayers...
Gandhi: Anybody can attend my evening prayers. How can I refuse you?
Arjun: Okay then. I will be with some of my ...
Gandhi: But not in these uniforms. Not with the revolver in your waistband.
Arjun: But Bapu ...
Gandhi: Why do you need the revolver?
Arjun: For your protection.
Gandhi: If somebody attacks me, you will shoot him with this revolver. Kill at the time of prayers?
Arjun: But Bapuji, if somebody attacks you ...
Gandhi: He is welcome. I don't mind my own killing, but I don't want anybody to die just for saving my skin.
Arjun: Panditji sent me. I am his bodyguard.
Gandhi: Then what are you doing here? Go, guard his body.
Arjun: Panditji said he had spoken to you, Sardar Patel also talked to you, but you are adamant in this matter. Today the intelligence bureau sent this file to Panditji. He has asked me to show it to you. Bapuji, you need protection.
Gandhi: I don't need protection.
Arjun: Bapuji... How can I convince you? Can you see the crowd gathered outside? One of them might be a killer, your killer. All the people attending the prayers are not devotees.
Gandhi: No. Only devotees attend the prayers.
Arjun: But those who threw a bomb here on January 20 were not devotees. The bureau has cracked down on them. Madanlal and Shankar Kistaiyya. They are talking. They are workers of the Hindu Mahasabha. Bapu, that bomb blast was not an accident. It was sabotage, it was an attempt on your life.
Gandhi: The Hindu Mahasabha and the Muslim League ... I don't differentiate between them.
Arjun: They don't understand it.
Gandhi: You are wrong Arjun: When I started the fast, both Hindus and Muslims put their weapons down.
Arjun: Bapu, a bullet does not differentiate between a commoner and a saint.
Gandhi: But the trigger-puller knows the difference.
Arjun: The refugees are furious. They hold you responsible for their massacre. The Hindu Mahasabha claims you are responsible for Partition. These handful of people are conspiring to assassinate you. It is dangerous to move around among the people at the time of prayers. Can you stop the prayers for a few days?
Gandhi: You want me to stop my prayers? It has never happened before. I did not let it happen. Be it imprisonment, detention, fasting or sickness ... I never let anything stand between me and the prayers. Kasturba was serious when prayer-time approached. I started getting up from her bedside. She held my hand, pressed it. I waited ... Ba slowly slipped into death. I got up and went for my prayers first, and then I mourned for my Ba. And today you want me to discontinue the prayers... for my life?
Arjun: But your life we need Bapuji.. all of us. That day you waited for some time for Kasturba, now for the sake of all of us wait for some days. If you want, let us pray here... You, Mahadevbhai myself, Panditji, we all will join the prayers... here.
Gandhi: And what about the people gathered outside? There could be one killer outside among them. But what about the others? They are not killers. I don't want to disappoint them for one Gandhi!
Arjun: But Bapuji...
Gandhi: Jawahar is childish, and Arjundas... you also. You are banking on the revolver that is in your waistband. My killer also has confidence in his revolver. I don't want to participate in your gun war. My weaponless confidence is much mightier than your gun-worn confidence.
Arjun: Maybe the weapons are small, but they do great harm.
Gandhi: That is the misplaced confidence of you gun-toting people. I was in South Africa, where Jawahar was not with me to protect me, the police hit me, imprisoned me. I didn't have a revolver, I had my confidence. Ultimately. I won the war.
Arjun: Bapuji, I am not talking about canes, I am talking about bullets.
Gandhi: I am talking about non-violence, a powerful weapon like non-violence.
Arjun: It is a question of a few days...
Gandhi: It is a question of principle. I am not immortal. I have to die one day. If my blood is going to cool down their anger, if it is going to stop riots and arson, if it is going to satisfy them that they have penalised a criminal named Mohandas Gandhi. I am prepared to give them my blood.
Arjun: Bapu...
Gandhi: I don't differentiate between Ram and Rahim or Krishna or Karim. I am not overwhelmed about the fact that I am a Hindu and I don't repent because I was not born a Muslim. I am I. And I am honest to my principles and to the truth. Arjundas you want me to discontinue the prayers for a few days... but I say, even today, if the killer is waiting outside for me. I am prepared to welcome him with folded hands. He can kill Gandhi, not Gandhism.
Servant: Bapuji...
Gandhi: Aah! Today I am late for the prayers. Arjundas, feel like joining me?
Arjun: But of course!
Gandhi: Come on. Excuse me, please. Keep your revolver here... beside my charkha.

Black out.
(Birla Bhavan. The prayer place is visible: It is a square cement block with greenery in the middle. A small lake is on the left and an arch-shaped, small, wooden bridge on it. Gandhi's sitting place is situated exactly opposite the lake.)

Nathuram: It was 4.45 pm when I reached the gate of Birla Bhavan. The security staff at the gate was scrutinising the crowd entering and I was a little worried about them. I mingled with a small gorup of people and sneaked inside.
It was 5.10 pm when I saw Gandhi and his close associates coming to the prayer place from his room inside. I approached the passage from where he was likely to climb the steps of the lawn, in such a way that I was covered by a few people.
Gandhi climbed the steps and came forward. He had kept his hands on the shoulders of the two girls.
The revolver was in my pocket, I released the safety catch. Though Gandhi was surrounded by people I was looking for an opening.
I wanted just three seconds more. I moved two steps forward and faced Gandhi. Now I wanted to take out the revolver and salute him for whatever sacrifice and service he had made for the nation. One of the two girls was dangerously close to Gandhi and I was afraid that she might be injured in the course of firing. As a precautionary measure I went one more step ahead, bowed before him and gently pushed the girl away from the firing line.
The next moment I fired at Gandhi. Gandhi was very weak, there was a feeble sound like 'aah' from him and he fell down.
Those who were close to me saw the weapon in my hand. They rushed away from the spot. Gandhi had fallen to the ground, I was standing and the crowd had formed a ring around us.
After the firing I raised my hand holding the revolver and shouted, 'Police, police'. For 30 seconds nobody came forward and I scanned the crowd. I saw a police officer. I signalled to him to come forward and arrest me. He came and caught my wrist, then a second man came and touched the revolver... I let it go...

(Black out... Sounds of wireless, Hullo, Victor calling. Victor calling... Gandhi killed in firing. IGP and home minister rushing to Birla Bhavan. Inform the PM).
