A Tribute To A Magician

Martin Gardner is well known for his famous ‘Mathematical Games’ articles in ‘Scientific American’ magazine. He contributed that column for almost twenty years. It seems intellectual youths of the period between later 50s and early 80s enjoyed much of his puzzles.

For me, Writer Sujatha introduced Martin Gardner in his famous ‘Katrathum Petrathum’ series in Vikatan. In one of the article, if I remembered correctly, while telling the ‘Lady or the Tiger’ story (I hope every one knows that story and its mathematical significance!) he told about Gardner and his famous ‘Mathematical Games’. Later, I found his ‘My best Mathematical and Logic Puzzles’ in central library of Karur. But the book is in reference section and I supposed to write down some problems everyday and tried solve it. Obviously, I even don’t understand most of the puzzles and give-up within a week.

Then during my under-graduation days, I once again gone back to Gardner, when one of my Math professor talk about recreational mathematics during an lecture. This time, I’m capable of solving many of his problems and got addicted to such puzzles. This practice fairly helped me while attending an bank exam (Cleared that exam but luckily or unluckily I opt to do Ph.D rather than to become a teller!).

Then, puzzles and Gardner gone into the thin air for many years. Few days ago, I don’t know how but, while searching some random stuff, I once again came across Gardner and found an interesting book, ‘Martin Gardner in the 21st Century’ by MAA (Mathematical Association of America).

Martin Gardner : The Puzzle Man (1914–2010)

Even though its a tribute edition, the book discussing the solutions of some of his famous problems, rather than discussing his contributions or his biography. Some interesting articles of Gardner are also included. Non mathematician may feel prosaic while reading the text, yet its a good book to give a try. At least one could wonders the usability and applicability of Maths in different arena.

To seek your attention towards the book, let me to tell you two tricks discussed in the book (Demonstrated!). First one is a coin trick named as three penny trick in the text. Consider three coins, which are placed in a row. You’re blindfolded and requested to assemble the coins in a way either all heads or all tails. The only condition you know is that there should be at least one head and one tail in the sequence. The idea is to flip the left coin first then the middle coin. Now check with the spectator, whether the required condition is reached. If not, go for one more left flip. Now it should be aligned in a way as requested, independent of whatever be the initial position. It may seems so simple. But when you replace the coins by cups and a question with the condition of at least three flips to achieve all-ups or all-down could be interesting.

The second is a card trick. Take about 15 cards and arrange them as 5 piles with each pile consists of random number of cards (say 4,1,1,5,4). Now remove one card from each pile and place the removed cards as a new pile. If the piles are arranged in a row, the new pile can be placed anywhere in the row, front, middle or at the end. Repeat the process, after ’n’ number of iterations, you always end up with an arrangement of 5,4,3,2,1. Depending upon the initial arrangement, the ’n’ may vary. But always end up with the above order!

Some more interesting problems such as Courier problem, RATWYT and Monty Hall Problem (MHD) are discussed in the book (There are three doors and opening one particular door would leads you to a car. Another two will leads to a goat. Now you allowed to choose one door, say A. Then either one of the other two doors will be opened, but not the door with a car. After this you have an option to switch from your selection. Even though it seems 50–50 problem, its not actually. There are many famous solutions available for this problem.).

Gardner not only wrote about Maths and Maths articles. He had wrote two novels, many books on magic and many short stories. Two of such short stories are also included in the book. The last one (both in the book as well as by Gardner himself) ‘Superstrings and Thelma’ is enough to showcase the Gardner’s writing skills to captivate the reader.

The only book reviewed by Gardener is also included in this collection. The book’s ‘name is ‘popco’ and in which the grandfather of lead character was influenced by Gardner. It is such a modest and appreciable review with the summary of the novel (He doesn’t disclose the climax). He complains about only one thing, about the usage of ‘f’ word through out the text!

With lot of maths the book may persuade somebody towards the subject. For others, especially those who interested in early bird numbers, flexagons or how to find the cube root of 52367419803 or any equivalent number in seconds may try once.

தமிழ் கவிதை

ஏறத்தால இரண்டாயிரம் ஆண்டு பாரம்பரியமிக்க தமிழின் தற்கால புதுக்கவிதைகள் பற்றி எனக்கு தீராத சந்தேகங்கள் பலவுண்டு. அவற்றில் முதன்மையானது, நிசமாலுமே அவையெல்லாம் கவிதைகள் தானா என்பது.

தாய் தமிழ்னாட்டில், போலி ரேசன்கார்டு நபர்கள், வந்து குடியேறிய பீஹார்காரர்கள் உட்பட ஏறத்தால, ஏழு கோடி பேர் கவிதைகள் எழுதுவதாக ஒரு புள்ளி விபரம் சொல்லுகின்றது. வெளியிடும் ஊடகங்களைப்பொருத்து மூன்று வகையிறாவாக பிரிக்கலாம். ஆனந்த விகடன், குமுதம் மற்றும் தினசரிகளின் ஞாயிறு மலர்கள் போன்ற வெகுஜன ஊடகங்களில் எழுதுபவர்கள். மொத்தமே பத்து பேர் தான் படிக்கும் தடம், உயிர்மை, காலச்சுவடு போன்ற வந்த, வரவிருக்கின்ற, நின்ற, நிற்கவிருக்கின்ற இலக்கிய இதழ்களில் எழுதுபவர்கள். இவர்கள் தவிர்த்து ஓர் ரகசிய இயக்கமும் உண்டு. தானே எழுதி, தன் தாய்க்கும் தாரத்துக்கும் கூடத்தெரியாமல், ரகசியமாய் தானே படித்து ரசிக்கும் ஒரு கூட்டமும் உள்ளது. ரகசிய இயக்கம் குறித்து நாம் அஞ்ச தேவை இல்லை. இலக்கிய பத்திரிக்கைகளில் வரும் கவிதைகளை அவற்றின் ஆசிரியர்களே படிப்பதில்லை என்பதால், அவற்றாலும் சிக்கல் இல்லை. ஆனால், வெகுஜன பத்திரிக்கைகளில் கவிதை எழுதி இலக்கியத்திற்க்கு சேவை செய்யும் சிலரால், தொற்றுநோய் ஒன்று வேகமாக பரவி வருகின்றது. (இவன் எழுதி இருக்கற மாதிரியே நேத்து டாய்லெட்ல இருக்கும் போது நாமக்கும் ஓன்னு தோனுச்சே.. அடுத்த தடவ அத அப்படியே அனுப்பிட வேண்டி தான்!)

சுஜாதா ஒரு முறை எழுதியிருந்தார், புத்திசாலித்தனமான வரிகளை உடைத்து வைத்தால் அது கவிதை அல்ல என்று. ஆனால் இன்று கவிதை என்று எழுதப்படும், பெரும்பாலானவை வெறும் வார்த்தை விளையாட்டுத்தான். விகடனின் இந்த வார இதழில் வெளிவந்துள்ள (90ம் ஆண்டு சிறப்பிதழ்) கவிதை இது. “திருமண தகவல் மையம் சென்றிருந்தேன். அநேகம் பெண்கள் சீசர் போல் நெப்போலியன் போல் ஒருவன் வேண்டும் என்றிருந்தார்கள். நேற்று ஒரு நெப்போலியனையும் ஒரு சீசரையும் தெருமுனையில் பார்த்தேன். விவாகரத்தான அவர்கள் தனியாகத்தான் இருந்தார்கள்.” படித்து முடித்த உடன், “கவிதையா?? இது கவிதையா??” என நானே கேட்டுக்கொண்டு இரண்டு முறை சுவரில் முட்டிக்கொண்டு (வேறு என்ன செய்வது?) அடுத்த பக்கத்துக்கு சென்றேன். வாசகர் கவிதைகளை பிரசுரிப்பது எப்போது தொடங்கியது எனத்தெரியவில்லை. ஆ.மு.வில் (ஆன்ட்ராயிடுக்கு முன்பு) கவிதை உதித்தால்(!) உடனே ஒரு 25 பைசா போஸ்டுகார்டு வாங்கி எழுதி ஏதாவது ஒரு பத்திரிக்கைக்கு அனுப்பிவிடுவார்களாம். கவிதை வந்தால் தமிழுக்கு சிறப்பு, வராவிட்டால் வரலாற்றுப்பிழை. ஏதோ தமிழுக்கு என்னால் ஆன சேவையாக 25 பைசா என்பது உள்ளிருக்கும் நீதி.

இமெயிலும் வாட்ஸ் அப்பும் வந்த பிறகு, தமிழுக்கான சேவை வரி நின்றது தான் மிச்சம். ஆசிரியர்கள், செயலியிலேயெ முடிவெடுத்து அச்சுக்கு அனுப்பி விடுவதாக பேச்சு. கவிதைகள் அளவுக்கு கட்டுரைகளோ, கதைகளோ, நாவல்களோ எழுதப்பட்டதாக தெரியவில்லை. காரணம் எளிதானது. மற்றவை எழுத கொஞ்சமாவது விசயம் வேண்டும். சிறப்பாய் வேண்டுமெனில் அனுபவம், அறிவு, பொறுமை தேவை. ஆனால், இவை ஏதும் கவிதை எழுத தேவை இல்லை என்பதால் தான், “மொட்டை மாடி நிலா பால்கனியில் கலா

வந்ததே காதல் விழா” என கவிதை செழிக்கின்றது.

தமிழின் ஆகச்சிறந்த கவிதைகள் எழுதி முடிக்கப்பட்டு விட்டன என்பது என் எண்ணம். ஆகவே கவிதை எழுத கை அரித்தால், கம்பராமயணத்தையோ, கபிலரையோ படிக்கலாம். படித்தபின்னும், நமநமப்பு இருப்பின் நிச்சயமாக எழுதலாம். சமீபத்தில், பெண் கவிஞர்கள் குறித்து ஜெயமோகன் தடம் இதழில் (செப்டம்பர், 16) “அவர்களுக்கு (பெண்கள்) தீவிர வாசிப்பு இருப்பதில்லை. அதனால் படைப்பில் ஆழம் இருப்பதில்லை” என்றிருந்தார். ஆண்டாளில் இருந்து இன்றைய தமிழ்நதி, பரமேஸ்வரி போன்றவர்களின் தீவிர ரசிகன் என்ற முறையில் இந்த கருத்தில் எனக்கு உடன்பாடு இல்லை. மாறாக, இதை பொதுவாக வைக்கலாம். நல்ல கவிதை படைக்க நல்ல வாசிப்பு வேண்டும் என்பதாக. 9ம் நூற்றாண்டின் கடுமையான ஆணாதிக்க சட்டகத்துக்குள் இருந்து கொண்டு, பன்னிறு ஆழ்வார்களுள் ஒருவராக உயர்ந்ததற்க்கு, ஆண்டாளின் பக்தி மட்டுமே காரணம் அல்ல. பெரியாழ்வாரின் புதல்வி, அவரைப்போன்றே இலக்கணம் கற்றுச்சிறந்திருந்தது தான் காரணம்.

பி.கு. நல்லா இல்லாத கவிதைகளை சொல்லி விட்டு நல்ல கவிதைகளை சொல்லாமல் விட்டால் எப்படி? சாம்பிளுக்கு மூன்று.

Free and Open Source Grammar Checker

Many typesetting packages offer spell check as a default option and this is true even in the case of open source packages like Libreoffice. But anyone looking for a style and grammar checker, always redirected to numerous paid options.

So, one Daniel Naber of Bielefeld University, took this problem for his thesis and developed an open source code for style and grammar checker, which is currently available for everyone in the site http://www.languagetool.org. The site offers an online checker, and browser tools such as firefox and chrome extensions.

In addition, as an offline support, Libreoffice and OpenOffice extension is also available. Thus by installing the extension into your Writer, you will get a curly blue lines under the text with errors. Like any spell checker, by clicking the corresponding word/sentence you can get the suggestions for that error.

Here I brief the installation of LibreOffice extension in Ubuntu. For stand alone usage consult the website.

Language tools requires Java to run. If you’re using Ubuntu 16.04, probably you have a Java environment of version 8. For those who are using Ubuntu 14.04 or less, supposed to update (or install, in the case if you don’t have) the version. To check the Java version type the following in terminal

sudo dpkg --list | grep -i jdk

The output should show something like, openjdk-8-*. In case if you don’t get anything, you have to install the environment in your machine. The commands are as follows:

sudo add-apt-repository ppa:openjdk-r/ppa sudo apt-get update sudo apt-get install openjdk-8-jdk

To verify the proper installation once again try the command

sudo dpkg --list | grep -i jdk

In case, if you have some older versions in the system, configure Java to make sure you’re using the latest.

sudo update-alternatives --config java sudo update-alternatives --config javac

Sometimes, there is a possibility of errors due to the older versions. In such a case, it is better to remove the Java completely from the system prior to the installation of latest version. To remove,

sudo apt-get purge icedtea-* openjdk-* sudo apt-get autoremove

Once again, in order to make sure that no Java in the system issue the command sudo dpkg --list | grep -i jdk . Then follow the installation steps, as mentioned above.

Now, go to the http://www.languagetool.org site and download the LibreOffice extension file (.oxt). The file can be installed either by double clicking the same or from the LibreOffice extension manager. For the second option, open LibreOffice writer and go to Tools >> Extension Manager >> Add. By choosing the languagetools.oxt file, it can be installed. In case, there is an error (for Ubuntu only), install the following:

sudo apt-get install libreoffice-java-common

You may still need to configure something, if the extension doesn’t works. Go to Tools >> Options >> Language Settings >> Writing Aids >> Edit and check Language Tools. To verify the installation, type (as suggested by the developer!) Feel tree to call. If the extension is working it will show a blue curly line under tree and suggest you to change to free!

PS: If someone really interested to learn what’s inside the black box, can look into the developer’s thesis: A Rule-Based Style and Grammar Checker and for those who wish to contribute the further development, can look into the source at Git-hub repository: LanguageTool.

INO — Myths and Truths

Once again India based Neutrino Observatory (INO) begins to appear in the headlines of newspapers. As a physicist I hope, I may have a slight better understanding than the fellow layman’s. This is what the result of that confidence.

So, long long ago, in the 60’s India pioneered in the neutrino research. First Muon flux density related research article was published from the results collected in Kollar gold mine. Those details are greatly explained by our former president APJ Abdul Kalam in one of his article in The Hindu (Dated: June 17, 2015). Once the Kollar was shut down researchers were supposed to leave the field and are looking to establish a research observatory somewhere else. This begins with 80’s and the proposal was got ready around the new millennium and sanctioned during the last UPA term.

Initially, Nilgris was the targeted place. But then Minister of Environment Jairam Ramesh rejected that proposal on the fact that the place comes under Mudumalai Tiger Reserve. So, that the Potipuram village of Theni comes in to the limelight. Some people worrying why not Himalayas? Why its particularly in Tamilnadu? The answer is geologically simple. The western ghats are much older and much stronger than Himalayas. Also, a single charnockite rock based mountain is preferable and that’s why the choice is Potipuram.

First voices against the observatroy were raised not from TN but from Kerala. The then chief minister Achuthananthan expressed his concerns on environmental pollution due to the constructions and he afraid the explosives used to break the mountains may damage the Mullai-Periyar dam, which is situated at a distance around 100 Kms from the Potipuram. Even though his concerns on pollution should addressed properly, the effect of explosives on the dam would highly negligible. Iduki, the place where the dam is situated, itself running lot of hydro-thermal projects with lot tunnels! Also, I don’t think government of TN would risk on a project which could damage that particular dam. All over the years, TN has struggled to keep the dam and I hope it wont risk on such a sensitive issue.

After Achuthananthan, Vaiko of MDMK party and G. Sundarajan of “Poovulagin Nanbargal” brought the issue to the court and National Green Tribunal (NGT). Even though, both are highly reputed activists and stand for many issues of TN, this time I think, some concepts misleads them.

The following points are the accusations aroused by the INO opposers. (1) It will induce radiation effects (2) It will pollute the area, since they are going to break the mountain entire village will be demolished (3) It will be used to store the radioactive wastes and

(4) It will be used to monitor some rogue nations nuclear weapons, since there is the collaboration of Fermi lab, India doing the things in favor of USA.

Selected INO region in Pottipatti, Theni

Let us to see the things point by point. Firstly, Neutrinos are everywhere, the mean time you’re reading this, crores and crores of Neutrinos transmit across you. The sun, the stars and the galaxies produce much and much neutrinos and they are available every where in the universe. Since they are highly non-reactive, we need a specific isolated place to capture them. Otherwise, there isn’t any possibility of radiation from the observatory.

Secondly, for the observatory a cave of diameter 2 meter only going to carved and with much modern state of art instruments it wont create much pollution in the area. Recently a TNEB project was established in that particular area. Experts say, pollution from the observatory would be much lesser than that TNEB project. Also, locals afraid that thousands of gallons of water will be sucked from their source. But TIFR assuring, only a limited amount of water, which couldn’t affect peoples usual usage, will be utilized for the observatory.

Thirdly, there is no need to store radioactive elements in such a observatory, with this much of huge spending’s, in a place like lone mountain range. Once when there was research activities in Kollar, people thought that DAE hiding nuclear wastes there. But now its clear that no such activity was ever happened. This would suits to Potipuram observatory too.

Lastly, there are natural and artificial neutrinos. Artificial neutrinos are produced during the nuclear fission in reactors. By capturing those neutrinos we could measure the amount of plutonium produced during the uranium fission reaction. (Uranium is used in nuclear reactors as fuel. By enriching the byproduct Plutonium, from the reactor, atom bombs can be made.) It is proposed that (some experimental evidences too available) by setting up a compact, dynamic neutrino observatory we could monitor the amount of plutonium produced in the area of interest (an another fact is that — they are actually measuring anti-neutrinos for that purpose).

But the point to be noted here is, for such a purpose, you don’t need to dig a cave in a remote village. With all these doubts and questions what is the importance of such a observatory? The answer is to know more about a fundamental particle called Neutrino!!!

Initially people thought neutrinos (there are three types of neutrinos) are mass less, but recent studies shows that they could have some mass. Measuring such a things would greatly help us to understand the properties of the particle. Which could, on the other hand, will enhance our knowledge on the understanding of the universe. So its basically a basic science. One reasons for the slowness in this project is not many people would be benefited from the project. A few of locals may get jobs in the observatory. There is feeble possibility of development in that area. So people wonder why this much of spending is essential? The answer if some one asked what is the use of general relativity and quantum mechanics (in the sense of basic science) in the days of their development and restricted the research, now you probably can’t use GPS in your SMART phones!

Customize Your LaTeX Bibiliography

Eventhough LaTeX offers wide range of bibliography options — Supervisiors/Editors/Publishers never satisfied with the defaults and here’s the way to meet their expectations.

If you’re an LaTeX user and whenever you’re ready to submit a paper, you should probably come across a request on slight modification of your bibliography style. Something like:

Why don’t you emphasize your title? You may add a semicolon between author names! and so on…

It become so hectic when your journal has a specific reference style and which does not falls on any category of the default bibiliography styles. One way to solve the issue is to type the references as bibilography list like this:

\begin{thebibliography}{}

\bibitem{Manaa2009}Manaa,
Hacene, Abdullah Al Mulla, Saad Makhseed, Moyyad Al-sawah, and Jacob
Samuel, Fluorescence and nonlinear optical properties of non-aggregating
hexadeca-substituted phthalocyanine, Optical Materials, 32, 108-114
(2009)

\end{thebibliography}

But this is always not so easy. Especially, when you’re supposed to resubmit the manuscript to some other journal, once again you have to modify every thing. So, the better way to play along is to generate your own style file (.bst) with specific contents. Let me to begin from the scratch. When you include a bibliography with bibtex, you typically have a structure like this:

% File main.tex \documentclass{article} \begin{document} \end{document} \bibliographystye{plain} \bibliography{list}

Here the list indicates the file list.bib, which contains the bibliography in bibtex style and the plain indicates the bibliography style to which the input is to be formated. Most of the time you can choose your style from the defaults and they are listed here.

To creat the the custom bibiligraphy style file, open a terminal and type:

latex makebst

This program will ask you questions and build a custom bibliography style. It’s a lot of questions, if you’re unsure just press enter and it will select the default values. At the end it will ask you if you want to proceed to compile your bst file. Once you agree, your specific file will be created. For minor corrections you need not to run the entire program. By simply modifying the (.dbj) file generated along with the (.bst) file can be used for that purpose. Once you modified the things by running latex mystyle.dbj , the (.bst) file can be altered. The complete log file designed to fit the requirements of the journal “Applied Organometallic Chemistry” can be obtained here.

To apply your new style (let’s assume you assigned the filename mystyle.bst), issue the following commands to install the style file locally:

mkdir -p ~/texmf/bibtex/bst cp mystyle.bst ~/texmf/bibtex/bst/ texhash ~/texmf # Make TeX aware of what you just did

Alternatively, placing the file in your working directory will also be fine. Once you have finished this all, apply the bibliography style in the main.tex file.

\bibliographystyle{mystyle}

Submit, grab a cup of coffee, and relax.

Windows Makeup Story

This is how to makeup your hate to perform like your love! It’s not a hate story but a make up story!

First let me to swear that I’m a diehard Debian and I never or will ever have an affair with this windows. But sometimes or most of the times (if your guide is not familiar with linux) there is no option but using the cracked windows. So this short note is for those who (like me) expecting some linux flavor when dealing with windows. Some this features are now available by default in windows 10, this one is just for win7 users. First and foremost thing I don’t like in windows is its welcome screen. In Linux (Especially in Ubuntu), you can easily customize your login screen. I personally prefer my wallpaper as the welcome screen. So, if your pictures folder or your picture has the read+write+executable (chmod 777) permissions, your wallpaper would be your login background. Windows by default not offer this feature. But by altering system configuration file you can do that. This link provides those instructions. Alternatively, third party tools such as Windows Log On Background Changer (I prefer this) can be used to simply change the background of welcome screen.

The second and most expected Linux tweak for windows is “open folders as tap”. And of course windows by default not offer this one and you’re supposed to look for some third party tools. Two famous tools are Clover and QTTabbar. QTTabbar is an open sourceware and it is in active development. But for me Clover suits well. (One thing and the only thing I don’t like in Clover is its icon. It’s like a green flower. Personally I don’t like it!).

Tabs in Windows as like in Ubuntu

One more tweak I really like in Linux is “open terminal here”. Surprisingly without much effort, by clicking shift+right mouse button, you will get a dialog box with “open command window here”.

Open Command Window here!

Then there comes our latex. Like I don’t like windows, I don’t like MikTex too. I prefer typing in gedit and compile it using texlive in terminal. Gedit has a windows executable and its working fine, except the thing when you open the second file, it will be opened as a new window instead of a new tab. Like in Linux, installing the complete texlive package is simple in windows too. Download the image file (.iso) from here and mount it using any of the following, such as WinCDEmu , daemon-tools , or Magic ISO . By running the batch file install-tl-windows it can be installed to your system. And like in linux it can be run from the command window (terminal) itself.

LaTeX in windows command prompt

One more thing I prefer that windows should have is, “always on top” option. Like the all above, using a third party tool called “always on top” we can achieve that goal. You have to run this script first, and then have to press ctrl+space bar on an active window to have it always on top. By pressing the ctrl+space again will revert you back.

Patna.. Patna..

Had an adventurous day and explored Patna in depths. Wish to motivate some others to explore the city with some facts.

When talking about Patna, its better to start from its roads. The roads are constructed during the period of King Ashoka and are still in use. If you are lucky some 100s of years old road stones may be thrown at you by the kids playing along the road. The drivers are extremely friendly and whenever two vehicles from opposite directions meet, they have a chit chat for a while. So unbelievably you can ride a 38 kms in just 3 hours.

You can start to explore Patna from its railway junction. From there many buses available to reach a famous place called Gandhi maidan. It is expected to spend your time fruitfully even in your travel. So they are freely teaching some “bowing” poses so that you can aware of how important is self control. Sadly they don’t consider people whose height is less than 4.5 feets as grown up and excluded them from this practice.

Once you reached Gandhi maidan you can start to explore the place from any direction. If you still have stamina even after the bus exercises, the better place to visit is Golghar and this one was built by British for storage purpose. Once you step up to the top of the building through its lengthy steps its hard to control the desire of reaching ground by jumping from there. Some times if more than 5 people are there, you may not get a space to execute your jumping experiment. At such a times they have an another set special stairs to get down.

Patna Museum : Entrance

One of the important place you should not miss in Patna visit is Basantha Vihar restaurant. It’s just near Patna museum but still you can reach there only if you are scored atleast a 90+ in geography during your high school. For those who scored below 90 can follow the guidelines below: Take a left from Patna police station, cross the road, you will see an big plaza, take an right and get into it. Go straight, then take a left, go straight, again left, then go straight; now if you have no problems in your eyes you can clearly see the Patna police station again (unable to see?? Heard some good eye specialists are available here!) Dont loose your heart and now you have almost reached the destination. Take a left again and go straight. Ahh.. You should be excited. Once you stepped in there, water will be provided with in 15 minutes of your entry and order will be taken in another 15 minutes. Then pickle and salt like items will be served by the next 30 minutes and towels and tissues will be served by the next 15 minutes. In such a heavy hospitality your hungry should be already vanished. If you are still in hungry you can check the prizes in the menu card once more to get ride of it.

From Basantha vihar you should go to Gandhi maidan again to continue your exploration. It’s very very near to our restaurant and just by the walk you can reach there with in a hour. From there to visit Ganga Ghat there is shortcut run on the sides of the maidan. If you are tired of the walk, you will refreshed by the sand breeze freely available in the maidan. Once reached the other side, you have to pick an auto, preferably with an old driver. He will teach you the meaning of budhism and the effect of karma. Since Ganga Ghat is a holy place such a lesson is mandatory to enjoy the atmosphere there. Again a 20 minutes of walk will take you to the holy river.

The return from ganga ghat should be by a bus. So that you can understand the basics of crystallography. They beautifully allighned people inside the bus even with their water pots and rice bags. The bus with the capability of carrying 25 humans are heavily doped and converted to carry 4 times than the actual. If you are not happy with 3D packing in the bus you supposed to walk again a 25 minutes to reach our old destination Gandhi Maidan. Apart from the jokes (or reality!!) Patna museum is one of the important places you shouldn’t miss in Patna. Again in a British building some wonders dated back upto 1st century AD is beautifully kept here. Many sections are dedicated to different era with different themes. (Even a section is available for Rahul Sankiruthiyan’s collections!!) Some astonishing Bihar paintings and some Ajantha Elora paintings are available in the first floor. Actually it’s a day out. But a day is not enough to explore either the city like Patna or even its single museum.

Madhavi’s world

Only very few authors can touch your soul, only very few can impress your thoughts and only very few can inspire you. Madhavikutty (Kamala Das) is one of such authors.

Yesterday I was gone through a book with some of her selected works, “Intha piraviyil ivalavu thaan (Only this much, in this life)” translated in Tamil by Pugazhenthi published by NCBH. The book is comprised of three parts: First part covers the thoughts of an elderly women who is miserable of her health, her late husband and people’s critics.

Yet there flows the love and confidence all over her texts. She shares her worst dreams, convey her concern on children, worries about the tress and ponds of her village Nallappattu and her conversion to Islam. She seems like an old pendulum clock, oscillating between her past and the residues of her dreams, yet she sounds beautifully.

She speak about her silence on criticism. She says, “I am an Eagle staying in the nests of Parrots. If I opened my wings the nest will be into pieces so its better to be quiet!”. The second part consists of very few of her poems. She is addressing her worries and wounds of life to Allah.

The soul that know how to sing : Madhavikutty (1934–2009)

Even with some breakages due to translation, still a reader can catch her thoughts. The third part consists some of her short stories. Often her writing is known for her boldness and for openly expressing truth. This book is also have such a nice collection of stories.

I wish to point out three stories from the collection. First one is “Swayamvaram”. Its about an old beggar woman who thought herself as a princess of Avanthi. The story reveals how even in the small world of beggar women the evil hands of society pokes and kill the dreams. The end lines of story will make every male to shy about their role in this society.

The “Red Petticoat” portraits the worlds of two different woman, a mistress and a maid, and their fears and thoughts. “Daughter of a freedom fighter” shows the real situation of persons who spill their blood and spoil their life for the freedom of this nation. They were no longer required for us and they are just a symbolic of some fools who wasted their life.

Finally, after a long time a book impressed me very much, hope you can too like this.
