Ramblings
of a Bohemian
The whispering infection
South
Point High School in seventies was a different place to study. I am not aware
how it was done, but our HS registration applications were sent in such a way
that the entire lot of XI-D found ourselves sitting next to each other at
Jagabandhu High School. Girls were not there as their HS seat were somewhere
else. On the first day, it was Bengali exam and we found that barring four boys
from some other school, our room was only class XI D and so immediately we were
comfortable.
The
fun started just after the invigilator showed up, parents with their worried
but at the same time encouraging faces (a feat that can only been achieved by
parents of HS examinees, worries, concern, fear, encouragement, confidence all
such conflicting emotions get displayed on their face at the same time!!!) were
shooed away and so it was us and four hapless students at four corners of the
room and the poor invigilator only in the class room.
The
invigilator received the first shock when Amlan found that the fan above his
head was showing tremendous inertia of going from a state of rest to that of
motion. So Amlan decided that application of the proviso of Newton’s First law
is necessary and with his voice that has as much sweetness in it as in a dry
sand paper, he commanded the invigilator to get a bamboo and to give suitable
motivation to the fan to set it in motion. Such was the authority in his voice,
the poor invigilator obliged. That set the tone in the exam hall that we are
the master and the invigilator should be available at our beck and call. After
we are all South Pointers, that too XI D!!!
There
was a gap of about one hour or so between the first and second paper when we
were met with not only guardians but also the teachers from school who had
equally worried faces. It was rumored that Arup Ratan Gupta’s parents had
rented a room next to Jagabandhu where he used to disappear for the last minute
study for the second paper. I am not sure about the veracity of the rented room
but it is a fact that Arup was nowhere to be seen during this one hour. For the
rest of us, it was a feast of our favourite snacks. Like for me it was two
massive gulab-jamuns with Lassi laced with green mango syrup. We would be
prodded in vain by our mothers to take a look at whatever they felt needed to
be looked at but we were too busy chatting amongst ourselves.
Pradip
was sitting next to me and just behind me was Sumantra Sen. In front of us were
Arup Ratan Gupta and probably Pradipta. English second paper translation landed
me into trouble, it was a passage about the vagaries of farmers. Most probably
I didn’t know the word plough or my memory had failed me. PD was doing some
other passage. I asked him for help but I think memory had failed him too. So
what I got from some unintelligible utterings, which was, nowhere near
something used by a farmer. I still remember my brilliant (?) improvisation of
calling a plough “agriculture instrument”!!!!
South
Point had turned all of us into paper guzzler. My physics paper script was 30
plus pages for each paper. But the
unbeatable one was Madhujit. He was consuming paper at a speed of one extra
sheet, which is four pages every two minutes. His handwriting had come to two
words per line and three lines per page. I think a forest must had have been
fell to supply all the paper we consumed during those six days.
The
last day, it was Mechanics, was fun. Specially the second paper in the
afternoon, when we could see the end of the long and tedious journey of last
three years and the final end the school days and beginning of what we thought
to be our freedom. So the scene in the exam hall became more of chat and less
of exam. The discussions ultimately landed into what movie to be seen based on
what movie someone else had seen already. The two most discussed one were
Jana-Aranya and Kabhie-Kabhie. So the interpretation of various scenes of
Jana-Aranya was being given. I recall the most discussed one was an alarm clock
shown in the movie. The incisive analysis of the presence of the clock, its
inner meaning and interpretation of the hour and minute hand of the clock and
their relative position probably would have befuddled the film maestro himself
making him wonder whether he had thought of such deep end of the presence of
the clock.
Discussion
on Kabhie-Kabhie was even more interesting. One can recall that it was one of
those complicated movies not on a love-triangle but on a love-marriage web,
like X is in love with Y but marries Z who is in love with W who marries U who
wanted to marry Y. To make matters worse, the makers of the movie made such an
entanglement spanning over two generations with a cross-connection of
intra-generation. So for the scientific minds of SPHS XI D it was a challenge
to be thrown at each other to see the deciphering ability of the other person.
The invigilator was initially looking very happy; after all he was getting a
very multi-perspective review of the movies from brilliant minds like ours,
which no newspaper film critic will ever give. But then he realized that the
matter is getting a little out of hand and tried to stop us and make us get
back to mundane stuff like solving motions of particles and accelerating or
decelerating trains.
The
Midas touch of SPHS authorities by making us sit next to each other did not
result in purely pleasant experience for all of us. It had its pitfall too.
That happened in the First paper of the Maths exam. There was this problem
where they give you some number power upto some other number and ask you to calculate
the number of digits of this contraption. All you have to do is to take the
logarithm and take the integer part called characteristic and add one to that.
Now I never could remember whether to add or subtract. So I always used a
trick: take log of 100 to the base 10 and that’s 2 and 100 has three digits so
add one!
Now
all of us landed with characteristic of 20, which is pretty neat. Sumantra
whispered from behind “Boss, the answer is 19 right!” Ok we got 20 and he says
19. So we didn’t think and wrote the answer to be 19. PD heard the same whisper
and wrote 19. The whisper spread like infection and all of us landed with 19.
Exam
over, and before going out and facing our parents proudly that all of us have
done 100 out of 100, we milled around each other. Madhujit, who had this odd
habit of always tucking his shirt end just below his elbow using one hand, came
towards us with his tucking speed doubled and grinning widely and said “That
answer is 21 isn’t it?” Now Madhujit’s seat was up there in the front a little
away from the other rows and on his other side was that nondescript student
from a nondescript school and so he was a little isolated acoustically from us.
So he was unpolluted from the infecting whisper and came out with the right
answer. Our jaws dropped. I mentally did what always I did and didn’t at the
most crucial moment: log of 100 is 2 and 100 is 3-didgit so add one. “OOPs!!!!
5 marks gone”. Our dream of 100 out of
100 shattered.
We
rapidly went into damage control mode. Result is three months away and lot of
water will pass under the bridge in the meantime. So result is not the crisis
but our mothers were immediate threat. So quick correction on the question
paper where we used to jot down the answers with pencil and an unspoken “omerta”
(code of silence). So when we stepped out, for our parents everything is
hunky-dory.
But
eventually it leaked out at least to Shyamadas babu. My poor cousin who was one
year junior to me and had landed in the Madhyamik trap, came to me seven days after
the exam. He whispered to me, “You have screwed up 5 marks?” I was horrified
and asked him how he had come to know of it. It seemed that Shyam babu has
found another new gimmick to drive home that one needs to be added by saying in
the tutorial of class X Additional maths “Pradip Dutta has made this mistake!
Arup Ratan has made this mistake! Debasish Som has made that mistake!”
We
have added another missile in Shyam babu’s arsenal and all for that infectious
whisper of Sumantra Sen!!!
My Sojourn with Mathematics
It
was the first week of June 1982. My father was posted in Midnapur. I was
staying there and was waiting eagerly for my Civil services Result. I was
reasonably confident that I will make it to IAS despite that being my first
attempt. Accessing the result from Midnapur was a
challenge. Somehow around 4 pm we managed to get our connection via urgent
trunk call (it was 1982; STD was rare, mobile and internet was very very in the
womb of future) with someone at PIB in Kolkata. I kept on listening to this guy with increasing incredulity as he rattled
off names after name but without any mention of my name. When it was mentioned
I had realized that whatever service I might land up with, it was not IAS. I
have missed the bus that year. I replaced the
receiver on the cradle and with a broken voice, tear in my eyes looked at my
parents and broke the news. For the next one hour, I sat shattered smoking
cigarettes one after the other. My parents left me alone though I could feel
the disappointment of my mother hanging in the air.
My father was far more steady and kept on explaining that competitive
examinations are like this and there is nothing to get shattered about.
By early evening I had got over
the shock. I felt mentally down, battered and bruised
but I was gradually recovering. Three of us had tea together and with a
chuckle, I told my mother that she is the most foresighted one. After all,
despite my serious objection, she had made me fill out the UPSC form and the
admit card for the Prelims which was ten days away
was already in her almirah. I had felt that filling up of the form was an
indication of my lack of self-confidence. I never realized before that day that
it was a folly and what my mother did was the smartest thing possible.
That was not
surprising also. It was because of my mother's insistent motivating push that
had induced me to explore the path of Civil Services Examination, despite my
deep love for digital communication. I already had appointment letters from
MAMC and CMC through campus placement, had topped
Engineering Service examination jointly with my classmate of many years (IIT
and Hindu School), Amit Haldar and had four or five offers from Central PSUs
like ONGC, NTPC, SAIL where I have appeared for the tests after applying through Newspaper advertisements just for fun and had
bagged offers as Management Trainees. So Civil Service Examination was an
ambition which had to be scaled but not the only option.
My mother's determination of
making me an IAS officer was not a recent one either.
It had started seven years back in 1974. One may recall that in 1974, the state
government engineers had gone a long strike. One of the demand was that
engineers have to be treated at par with IAS officers. My father was one of the
engineers who had participated in the strike. It is
not that he had any ideological inclination or sympathy for the cause but not
participating would have been an act of renegade on fellow colleagues and so he
joined. The eldest maternal uncle of my mother had visited us one day when my father was home as strike was going
on. Exchange of usual pleasantries ultimately took turn towards the ongoing
strike. My father explained the demands of the engineers. My maternal cousin
grandfather commented that whatever may be the demand
of the engineers, parity with IAS officers is an impossibility as no way
engineers can be compared with IAS officers who according to him were kind of
supermen. The word he actually used was a Bengali proverb that "Muri"
and "Murki" cannot be compared as the later
is much superior, metaphorically putting engineers as "Muri" and IAS
as "Murki". This statement infuriated my mother. She vowed that day
after the departure of her maternal uncle that her home would be endowed with
both "muri" and "Murki". The old
man had hardly realized that by making a statement, probably very casually from
his experience of seeing ICS officers in the pre-partition India from a
distance, he has changed the destiny of a school student.
I was then in class ten. I made it
to IIT and during the summer vacation of 1980 when I
was in my fourth year, my plans for having a nice time along with the summer
training was shattered when I was handed over a thick bundle of cyclostyled
sheets by my mother. They were the study material from
some study center and I was supposed to read them in the evening. They had the
usual general studies stuff. The general studies frenzy was in abeyance in my
final year as I was busy with my project works but immediately after that I was
seriously into studies of general studies along with
preparation for engineering service and Physics for Civil services exam.
Any way ultimately all these
culminated into my appearing in 1981 and the results came out in 1982 June with
me landing with some service but IAS.
I had appeared in 1981 with
Electrical Engineering and Physics as optional paper. Electrical Engineering
had sections meant for Electronics Engineers and so it was manageable. Physics
was my most favorite subject in school and I really excelled in that. I was in love with Physics too. So it was a natural
choice.
But falling in love with a subject
and exploiting that for an exam six years down the line is like a having
infatuation for a girl classmate in school and then meeting her after six years
and hoping that she is the same old flame is a little
too much to expect. So I read the books that I felt like reading in school:
Feynman's Lectures in Physics, Berkeley Physics Course (all five volumes),
Atomic Physics by Max Born and so on. They are great Physics
books, but they don't tell you how to write answers to Physics questions or
solve problems. I was having this uneasiness creeping all over me and tried to
tell my parents that I am having some difficulty. My articulation of the
specific nature of difficulty was very poor and
vague. So the conversations always took an ugly turn; I would be saying
something like, "I can't understand up to what depth I should read."
My father's response would be , "What do you mean by depth, read whatever
is there." My mother would be furious,
"only excuses for not studying...".. the typical response of bong
mother.
And I would clam up. That was the
end of discussion.
So finally when I landed up in the
examination hall for the Physics exam, I found that for writing the answers my knowledge is limited to what I have been taught
by Anjan Babu in South Point with the deductions being done with elementary
calculus. I could explain the theoretical questions but when it came to problem
solving, in some cases I just could not solve them
properly.
I wont say I came out disappointed
but I didn't also exactly walking on seventh heaven. My ignorance was literally
a bliss.
But on that fateful evening of
June, when I introspected I realized that my handling of Physics paper was just not up to mark and I had to do something about it the
next time.
It was about 11 pm or so when I
made my declaration, " I am not going to take Physics as optional, I am
going to take Maths." The silence that followed was deafening. Then my
mother broke the silence, " How much of the
syllabus you have covered in Engineering?"
Well, the fact is virtually zero.
In IIT we have done Applied maths and this is Pure Maths.
"I know the stuff; but the
approach is a little different" was my response hoping the discussion will stop there. But NO!!!!
My mother told me to get the
syllabus and made me go over item by item and tick or cross what I knew and
what I didn't. When I was done, there were more crosses that ticks and the
horror on my mother's face was as if the ghosts from
the near by cemetery is doing a tarantula dance in front of her.
The next three to four hours
should go down in history as the unique case study on negotiation; every
arsenal my mother had at her disposal, cajoling, psyching, sentimental pressure, anger, despondency, desperation, threat of
hunger strike everything was used to dissuade me from what she though was a
suicidal attempt by adopting maths. Calendar was brought, days till mains were
counted and all kinds of calculation by allocating
time for the different subjects was done; another case study of optimal
allocation of resources can be made out of the exercises that was done to prove
that I am proposing an impossibility. But somehow I stuck to my point and
finally at 4 in the morning, my father who was
sitting impassively listening to this epic negotiation and puffing his pipe
gave his verdict.
Maths is a go.
Why I did it? I had a secret
agenda too and a source of strength as well. The strength was Prof. G C Giri of
Midnapur College, a gold medalist of Calcutta
University (MSc in Pure Mathematics) who was doing his Phd at IIT Kharagpur. I
had befriended him during my journey from Midnapur to Kharagpur where he was a
daily commuter. I knew he would be able to guide me.
My secret
agenda was to learn mathematics as this will help me in my pursuit of Digital
Communication, one of the most Maths intensive subject of Engineering.
Two days later I went to meet my
mentor, philosopher and guide, Prof J. Das. I told him of my decision to change to Maths as optional. He was OK with that but he
had other concerns. He asked me "Do you propose to ever become a
Professor?" On a very strong negative reply from me, he said in Bengali
"Don't travel with your legs on two boats". It is a Bengali proverb meaning being a fence sitter and pursuing two
different objectives. So his advice was to go full throttle no holds barred
with Civil Services preparation and to give up pursuing MTech which I was doing
and was going to be in second year.
Again it was a watershed decision but it was easier one to take. So I left M.Tech
course and became an idea jobless unemployed young layabout.
The day after the prelims, I was
gifted with a small blackboard by my father which was hung up behind my chair
on the wall. On top of the blackboard was written
"120 days". Everyday that number will get reduced by 1 and that many
days I had at my disposal to learn mathematics.
My day started at 8 am and by 8:30
after having my tea and morning formalities, I will be at my desk. My father's orderly Sambhu-da will bring two packets of
Charminar Gold (packs of twenty cigarettes) and I will be at it. A lunch break
for an hour and a tea break for half an hour around 5:30, dinner break of half
an hour at about 10 pm were the only breaks. I had a collection of Ananda Shankar musics which
were constantly playing on the stereo system. My bed time was any where between
3 am to 4 am everyday.
But every week, on Friday a night
show movie at the movie hall Mahua next door was a must.
But the
days were fun. I was learning mathematics. There about in total 650 to 700
theorems and more than 1000 problems covering the syllabus. Most of it was new
stuff for me. A substantial part needed conceptualizing so that it could be
internalized. So many times my mother will find me
smoking a cigarette and looking out of the window at the expanse of the huge
ground with cows grazing with my foot up on the table and almost a lost look on
my face. Initially she thought that I was about to go asleep but later realized the importance of those trances.
Prof Giri was of great help. He
suggested me books, most of it from some publishers at Meerut or Delhi and
those books were like what K. C Nag used to be during Higher Secondary days.
Problems were annotated with the years they have
appeared in the Civil Services exam. Later I think, when I had about 35 days
left on my blackboard count downer, he started setting up mock question papers
and I have to answer them in exactly 3 hours. He will then correct it and my marks initially was very poor in the range of 170-180 out
of 300. Gradually it started improving and in the final days it reached almost
270-280 marks.
On 120th day I had to stop
studying Maths and get back to study General Studies and revise Electronics.
My 120 days sojourn with Maths was
over.
The movie we never saw:
I joined as SDO Rampurhat in September 1985. It was my first posting.
Rampurhat is one of the oldest subdivisions of West Bengal; a completely rural
subdivision with 8 blocks and 4 police stations. The Subdivisional Police
Officer was G M P Reddy of 1982 batch, who later became DG.
In the academy, there have been lot of discussions about the friction
between SDO and SDPO and one of the most contentious issue, we were told, was
the relative sitting position in a jeep. The custom is the senior officer sits
on the outside and the junior guy sits sandwiched between the driver and the
senior guy; the securities sit in the back. So Reddy and I decided that we
would improvise and beat all the pundits of the Academy hollow; it was decided
by following a simple protocol that on one way he will drive and the other I
will drive and driver will be relegated to the backside and there is no
conflict.
Till the time GMP was SDPO in Rampurhat, we followed this and it was a
great thing.
It was just after the Puja of 1985. Both of us were living as forced
bachelor and the offices were closed. So it was a slow day. We were sitting at
Reddy’s Bungalow and were having whatever lonely forced bachelors normally have
in the evening of a holiday. At about 7:30 pm we decided that we should go for
a movie. The only movie worth seeing was running in the movie hall of
Mallarpur, 15 km away from Rampurhat. It is a block headquarter but not a PS
Headquarter. So we drove down; I think I drove. After reaching we found that
the next show was going to start after one and half hour. So we decided to take
a walk incognito.
We strolled as ordinary people and at a road crossing, came across a
tea stall. We had advised our security guards to maintain a distance so that
nobody recognized us. We sat on the wooden bench of tea stall and ordered two
cups of tea. The old stall-owner gave us tea and looked quizzically at us and
asked, “Are you guys new here? Never saw you before?” We told him that we are
indeed new to that place but work there. “Oh! Do you work at the bank?” We did
not want to lie and so gave a vague reply. Both of us were enjoying
tremendously at our playing the modern avatar of Haroon-Al-Rashid.
Finishing tea, we walked some more but also asked our security to get
the jeep so that we could return to the movie hall quickly whenever we wanted.
We were walking down a dark road with a high wall with a steel gate on our
right side. Suddenly we saw a truck
coming out of the gate with all lights (both headlight and side light) switched
off. To us it appeared to be a suspicious move. So we waved the truck to stop
and called our security to ask the driver to come down. The driver gets down
from the vehicle and Reddy with his cop voice asked what he is carrying and
where are his papers. The driver could not produce any paper and said he was
carrying oil. The high walled compound apparently was an oil mill. So we asked
guy to reverse and get inside the compound and we followed him inside.
We went around and called for the people in oil mill and started asking
questions. While Reddy was quizzing the guys, I looked around and came across
some container carrying some oil, which did not at all look like mustard oil.
These people claimed that it was palm oil.
Now at that age, one is an eager-beaver officer always trying to right
all the wrongs and the world is full of crooks, who need to be caught and
punished. Ideology and all those lectures of academy still fresh in mind, we were
determined that we were the last crusaders fighting all evil. And here is an
evil act of adulteration being committed, which needed to be punished. So we
declared that we are seizing the truck which was carrying the same white
looking oil of indeterminate origin, which we were sure being used for
nefarious purpose and also all the containers in the mill carrying the same
oil.
So I told GMP that lets make the seizure list. GMP looked distinctly
uncomfortable and said that he has to summon the Circle Inspector. I asked him
why he would need the CI. He whispered back, “Som, I don’t know how to make a
seizure list under the Essential Commodity Act. I need the CI to make one!” So
he radioed Rampurhat and asked the CI to report to Mallarpur immediately. We sat
on the footboard and bonnet of our jeep and smoked waiting for the CI to arrive
while the mosquitoes had a delicious time feeding on us. The people of the oil
mill was rounded up under the watchful eye of the securities as we were sure
that they were the worst possible villains and but for us would have created a
huge black spot on the history of Human race.
The CI arrived with some more cops after one and half hour and took
over. It was 10:30 in the evening by then.
We didn’t go to the movie that evening.
I don’t know what happened to the truck and those people either!!!
Evolution of my Library
Back in 1973, when we lived in a Government Bungalow called Canalvilla,
situated at princely location on the corner next to Chitpur Bridge, my books,
all being school textbooks, were accommodated in a small wooden bookshelf.
Behind the books, I used the keep stuffs like storybooks hidden from the eyes
of my parents.
In that year, we shifted to our new home at Ballygunge Place and next
year I joined South Point. Sometimes in April/May, I visited Anjan Babu at his
home….his bookshelves full of Physics books kind of started a simmering desire
to have lot of books. Physics was the subject I fell in love..and Anjan Babu
introduce me to the world of foreign authors…Gamow: Physics Foundations and
Frontiers, Isaac Asimov: Understanding Physics, Greene: Physics, White: College
Physics. With interest grew my urge to buy books…it was in Class X and XI, I
bought Glasstone: Physical Chemistry, AJ Mee: Physical Chemistry, Piskunov,
Berkley Physics Course Vol I at a princely sum of Rs 10.75, Resnick and
Halliday, both the volumes,Scientific American Compiled Papers 3 volumes of
Physical Science…so the bookshelf was looking respectable. Along with that grew
my habit of scoring the railings of Presidency College, the bookshop on Dover
Lane, Oxford (those days they kept both science , mathematics and Engineering
books).
By the end of the fourth year and in final year of IIT Kharagpur, I had
fallen in love second time: with Digital Communication. That was the beginning
of my Digital Communication library…with Taub and Carlson, then Communication
Circuits by Clarke and Hess, Jayant: Waveform quantization and Coding, IEEE. I
got Dixon's Spread Spectrum Systems IEEE, Ash: Information Theory as a gift
from an aunt who was a resident of USA.
By the time I was due to leave for Academy to join IAS, my library has
grown to a respectable one almirah and one bookshelf full of books, about 40%
from the various subjects of B.Tech curricula like Millman-Halkias,
Millman-Taub, Taub-Schilling etc but along with that books on Physics (my first
engagement with Civil Services Examination) and Mathematics (my second and
final engagement).
My job kept me away from my quest of books and learning but in 1994,
when I came back to Calcutta and joined WBSEB, I had brought back from
Balurghat a Science and Technology encyclopedia. In WBSEB, amongst engineers
many of whom were academically excellent people, my old passion for
communication theory got rekindled and my library started growing in size. By
that time, I have been allotted the mezzanine floor room for my library and my
parents even sponsored a couple of very decent bookshelves to be built for
keeping my books.
It was around this time probably in 1995, I met Arabindada of Dasgupta
Publishers, who became a constant encouragement and supplier of books. He got
me my first copy of Courant's Calculus and Weyl's Space, Matter and Time, max
Born's Atomic Physics and umpteen books on Digital Communication and Spread
spectrum. On one trip to Hyderabad, I went to a bookshop where I almost went
crazy: so many books which I have only read about in the bibliographies… I
borrowed some money from my fellow colleagues and bought a suitcase full. Those
days in Hyderabad airport one had to walk on the tarmac from the terminal to
the craft and while I was walking, the straps of my suitcase weighing several
kilos broke; oops….dragged the beast somewhere.
During my tenure in KMC, I first bought books from Amazon. One librarian
in British Council where I have gone on some program and landed in the library
searching for Delta Modulation by Steele, told me about Abebooks.com.
Money was problem; my father being a strict disciplinarian and manager of my
money ( YES!!: He managed my money and I was only given a pocket expense when I
was controlling crores of government money as I didn't have the time and
inclination to manage anything other than my job) will not allow my book
expense beyond a point. Not that the salary was so princely as to afford
matching my hunger for books….but nevertheless I managed to buy books at
regular frequency. The two bookshelves were no more sufficient so came
third, fourth and the fifth…
Oh! Sometimes in 1999, I was told by a friend of mine working for
Prentice Hall of India that they have marked more than 5000 books for
destruction (yes destruction…they tear off the title page and the book as per
their accounting standards become valueless!!!) and these books are stored in
the garage of their MD at his house in Bansdroni. One saturday I went down
there, it was like two garages and the books were stacked without any space to
even walk between the stacks….so I took off my shoes and spent some four hours
going through rummaging the stacks and had about 150 books. They were loaded in
the boot of my ambassador staff car, the car's backside sagged; I had to give
up loading when my driver told me that the car could not be driven if more are
loaded….what books my God!!! Rare, relevant, hardcover, original US edition
…..its a treasure trove.
Tryst
with Mathematics
My love for mathematics started growing when
I appeared for civil services examination in 1982 with Maths as optional.
However the love remained dormant for many years but came out of hibernation
around 2009. I had been thinking of doing MSc in Mathematics in 2004 and had
even obtained permission of the State Government for appearing in the exam as a
private candidate. But it never happened due to work commitments. But in 2009
when I started looking for opportunities to do MSc, I found that the norms have
changed. One needs an undergraduate degree in Mathematics for doing post
graduation. I couldn't find any that
allows pursuance of an MSc by an Engineering graduate. IGNOU has MSc in
Mathematics and Computer Applications but the course content did not appeal to
me. It was closer to Computer Application than to Maths. I enrolled for MA in
Economics at IGNOU. I was then working for an Infrastructure Consultancy
company and thought a grounding in Economics will be of a lot of help to me.
With vigour I started reading microeconomics, which to my delight was
completely mathematical. However this effort fizzled out as the examination
dates of the first year coincided with the Board meeting date in he new job I
had joined just recently. That was the end of the MA in Economics. Moreover some of the subjects I did not like as it involved long
essays. So the appeal and excitement was not much in any case.
The next two three years I floundered
academically. There was no definitive direction of my study; i was wandering in
the alleys of mathematics like a rudderless and directionless boat, reading,
studying mostly things I liked and avoiding things I abhorred. Then suddenly
one day browsing the net I saw Netaji Subhash Open University eligibility
criteria for doing MSc in Maths to be only graduate in any science /engineering
subjects. Bingo!!! I tried to enroll but hit a roadblock. The online (and you
could apply only online!) format wanted Madyamik marks. Apparently they never
foresaw an old man like me from a prehistoric period when Madhyamik exam was
not even in existence applying!!! I called the Higher Education Secretary,
Vivek Kumar who was few years my junior and told him about my predicament. He
chuckled and told me that He will request the Vice-Chancellor to speak to me
and to sort out the issue. Any way Dr. Sarkar, the Vice Chancellor was very
kind and I was enrolled.
I received the Course material and started studying.
The first year was a little boring as I was reading all the stuff I had studied
during my civil services examination. But a huge shock was waiting for me. When
I started solving problems, I found I didn’t have a clue where to start, what
to write, how to build the logic of solving the problem. Last time I had done
that kind of thing was almost three decades back and I had lost the edge.
Staring from scratch, I gradually built up my skill and confidence over couple
of months. More importantly, I gave up most of my boozing activity specially
the customary chilled beers on Sundays and Saturdays as they played havoc with
my wakefulness post-lunch. So hard drinks was substituted with cold water. My
daughter was studying in Great Lakes at Mahabalipuram at that time. So our
trips to Mahabalipuram and stay at hotel was with the accompaniment of books on
real Analysis. Even on the day of cataract operation of my mother, I had taken
Algebra by Prof. Mapa to the Nursing home and solved problems while my mother recuperated.
In 2014 was the first year examination. It
was fun. The exam center was at New Alipur College. The exam was in
August/September and the weather was saltry, warm and humid. I am habituated in
working or studying out of an air-conditioned room, used to writing on decent
exercise books with roller ball pen which does not smudge. my study hours have
been spent on a comfortable well cushioned revolving chair. The exam center
environment was just the opposite in all respects. I was sweating profusely, my
fingers were sweaty and after few minutes the pen was slipping. So I had to
exert extra force to hold my pen. The sitting was on wooded bench as contrasted
to cushion support for my backside and the answer script was getting black
smudges on the other side. The paper was like a blotting paper and was sucking
ink hungrily and leaving black marks all over. So my handwriting, of which I am
somewhat proud of, went for a toss and it did not look like any handwriting
that I have ever seen in my life. I was guzzling water from the bottle I
carried mostly to recreate the environment of study room (that was the closest
resemblance I could manage) and to stop from getting dehydrated. But even then
it was fun.
I must say what happened on my Mechanics
paper. I loved the subject, had prepared with gusto and was very confident that
it will be a cakewalk. Now first problem, I made a wrong start. What ought to
have been done in half a page, went for three pages and I landed with an
equation with sixteen terms on each side and started struggling. This was not
what I had ever done with that problem!!!! It was probably a Poisson bracket
deduction. I went out for a smoke and tried to cool down, bring my panic level
down by telling myself that it hardly matters as I am doing all these for fun.
But I was unnerved and had a partial brian-freeze. So by the time it was over I
knew I have badly screwed up and possibility of failing in that paper kept on
lingering in my mind!!!
The other fun part was the reaction of my
co-examinees. They couldn’t figure out exactly what kind of an animal was I. I
was not a teacher, old enough not to be an aspirant for the post of teacher and
they were at a loss to figure me out. I saw lot of furtive glances full of
curiosity and decided that it was time to have some fun. So I opened some
cryptic dialogue with some of them. But the most disappointing thing happened
when the young girl co-examinees started calling me “uncle” and I realized that
I have started really looking old…..
The second year became even more exciting. I
started learning new subjects like Topology, Tensor analysis, differential
geometry (geometry of manifolds), Topological groups, topological vector spaces
and so on.
I had trouble with Topology. For some
peculiar reason, the concept was not getting clarity in my mind. I recalled
having a telephone conversation with Mr. Samar Ghosh, ex-Chief Secretary when
he had mentioned “He loves Topology”. So I called him one evening and told him
that I was having difficulty in Topology understanding. He suggested that I
read A textbook of Topology by Dr B C Chatterjee. That was a wonderful
suggestion….the book was like a poetry and opened up the inner beauty of
Topology to me.
The other person who helped me again over
phone was Prof. U C De. On the sufficiency of proving diffeomorphism, I called
him and sought his advice. “Which book you are reading from?” When I told him,
he told me that for a beginner that book might be difficult and suggested
Differential Geometry of Manifold which he has co-authored. That truly is one
of awesome books I have ever read. Even today when I study differential
geometry, that book is my constant companion.
The other amazing thing that happened to me
was with computer programming. I had always been very weak in this; the grammar
and syntax of a language always eluded me. We were supposed to do fifteen hour
of computer practical on five Saturdays. It was in New Alipur College. The
practical word is a misnomer. They give us few problems and also the program.
So one has to type out the program, debug it and then run it with the given
input and compare with the output that is also given. But what happens it,
suddenly you start getting the meaning of various symbols you have to type in
as a prefix, which indicates it as a constant or a variable and so on. After
you have done a couple of them you start getting hang of it and debugging
mistakes starts getting fewer and fewer. I found it very interesting and back
home I loaded it on a window laptop, I almost got addicted to it and started
writing programs that gave out stupid results, like the primes in the number
range from 1 to 10000000 and the list went on and on. Then started count of the
primes from different number range and was trying to get a hang of frequency of
occurrence of primes (You know Riemann’s Hypothesis is partly about it!!!!!).
However I landed with good mark in computer programming, which I did not know
anything about earlier and have worked on only for couple of weeks.
The exam of the second year was a non-event
excepting due to some other examination it was delayed by couple of weeks and
almost got close to Pujas!!
It was during one of the afternoons I was
studying Differential Geometry, that an idea occurred to me. I had stopped
studying and was contemplating the walls and windows, peeling painting, the
garbage, the kind only school students dump of South Point. The concept of
charts and atlas of a manifold started giving me an idea of looking at a spread
spectrum signal through frequency windows like one does in case of wavelet. I
felt that a deep connection exists between differential geometry and
Communication theory and wondered whether someone has explored it ever. I
searched the net and came across a name Prof. Shunuchi Amari and it seemed he had
not only written a number of papers on the subject but also did his doctoral
dissertation on the same subject. That was the beginning of my study of
Information geometry, Compressed sensing and Differential Geometric method of
Statistics which I am pursuing now.
In February 2016, one of my co-examinees sent
me a cryptic message “Result is out”. I had an idea that my marks will be
decent but results are results and even now hands tremble, knees weaken while I
search for my marks on the web despite it hold nothing for me except being an
ego-booster. Nobody else cares a damn about how I fare. I saw 824 against my
name. 824!!!! Nobody has ever got 824. I
browsed the site and came across someone who has got 819.
Later one gentleman who is aware of things as
he teaches students told me that nobody has ever got in the range of 700 even
with Pure mathematics. Applied Mathematics is much more scoring but not Pure.
He called it a miracle!!! I doubt the miraculous nature of the mark but
attribute it to something akin to beginner’s luck!!!!!!!
Anyway finally I was a postgraduate at the
age of 56.
CAT:
measuring brain power
I always wondered whether my mental agility
is going down with age or not. It was difficult to assess with the normal
chores of life, as any change will be incremental and hard to detect. Any
measurement will imply comparing with someone who has the highest mental
sprightliness at its prime. The most suitable place to find such best brains
will be what is considered to be one of the toughest exams CAT. I also thought
it will be great fun to sit there and to solve some challenging problems raking
my brain in a new environment.
In 2008, my daughter was planning to appear
for CAT as a dipstick test before she appears fully prepared. I kept on telling
her you don’t have to prepare with some exam like CAT; you just go and solve it
and that’s all about it. Of course I was in a minority. If you look around and
browse the net, you will find that people prepare for more than a year and
there are so much research on CAT, you feel scared and terrified about the
test. So the other purpose was to break this myth if not to the world, but at
least to my daughter and family that its no big deal. You just go and write it.
So I filled out the form along with my daughter and sent it.
The admit cards came as scheduled and the
exam center was at Pailan. So two days before the exam, I went on a
reconnaissance trip with a friend of mine so that the driver knows where to
take us without a hitch on the appointed day.
So we reached the hall on the date. But my
daughter was feeling so self-conscious about having her father tagging along
not to the exam center but to the hall and that too not as a guardian but as a
candidate, she flatly told me before getting down from the car “From now on I
don’t recognize you…I find it so awkward”. Great!!! We were in the same hall
and she stubbornly looked the other way whenever I looked at her and tried to
wink to humor her!!!
It was the last CAT with paper and OMR sheet.
From the next year it was all computerized. So the moment I got the paper, I
started solving the quant. To my horror, I was stuck at the first problem. Then
the second one too!!! And the third…. This was not something I had bargained
for. So I sat there and tried to solve them with all the brain computing power
at my disposal but I was missing something. Twenty-five minutes had passed by.
I longed for a cigarette; my brain screamed for nicotine. So I requested for
permission to go out.
One of the invigilators, a short plump middle-aged
gentleman had earlier come to me and told me, “Sir, I know you. You were
commissioner Kolkata Municipal Corporation.” Ouch!! I requested him not to
advertise that. So when I requested for permission to go out, he came to me and
said “Sir, after five minutes.”
I eagerly waited. After five minutes this guy
signaled and I walked out of the hall and lit up. Two drags and the solution of
the first problem that had eluded me so long, clicked in place in my mind. Few
more drags and the others followed suit. I finished my cigarette and came back
and started solving the problems.
2008 CAT paper was one of the most beautiful
papers of CAT. It had lot of nice challenging problems. Anyway I had lost
twenty-five minutes and was hard pressed for time already. So I did the paper
not entirely to my satisfaction. I came back home and after lunch with chilled
beer started solving the remaining of the problems. They were all gems. Some of
them were really challenging and needed lot of firepower. I enjoyed solving
them.
I landed with a percentile of just under 95.
I was not happy with the experiment. Lack of
nicotine seemed to have distorted the output. So another experiment was
necessary. In 2010, again I filled up the form along with my daughter.
The exam center was just behind Great Eastern
hotel. It was a known place for me as I had been there to chat with Vishnu
Mohta, one of the directors of Venkatesh Films, whose office was on another
floor of the same building.
My daughter had the same scornful attitude
about lugging along a parent who refused to behave and act as a guardian, a
befitting role for someone of his age but playing havoc with all sensibilities
by being a candidate with boys and girls half his age. As we descended form the
car and started getting onto the footpath and the gate, a security guard
stopped me and told me that guardians are not allowed beyond that point. My
daughter simply waved her admit card and vanished inside the gate without even
bothering to look back to check what happened to her poor father. A very
understandable reaction from her: if the father is denied entry, fine; he can
play the guardian and if allowed to enter, then he is another candidate without
any acquaintance with her let alone family ties.
I patiently waved my admit card to the
security guard who looked at it, looked at me and still had a huge doubtful
look on his face. I could feel he was wondering whether to give a shout at the
cops that someone is masquerading as a candidate in trying to get entry. There
was a continuous flow of dialog exchange going on simultaneously which is like
this:
“Sir, guardian
allowed nahin hain”
“Mein guardian
nahin, candidate hun!”
Finally he took a last careful look at my
admit card, my id proof of retired Government officer, made sure that I am the
same person and not someone in disguise or something and allowed me to enter.
Then there was this counter where they take
your photograph, check admit card, id proof, take fingerprint almost akin to
processing of a criminal at a US Precinct.
The gentleman who was checking these
documents looked at my id proof, looked at me and again gave the id proof a
hard look and decided a loony is at hand. However he sounded respectful and
processed me!!!
I proceeded upstairs and decided that it is
time I fill my blood stream and brain with enough nicotine to last at least
three to four hours to avoid a repetition of last time when nicotine deficiency
screwed up my experiment of measurement of mental agility against a proper
benchmark. So I smoked three to four cigarettes in quick succession and felt
the nicotine making me sufficiently high. I felt that two more measurements
might be necessary, one when one sits for CAT after consuming two bottles of
chilled beer and another with two large pegs of single malt. That experiment is
still pending!!!
Before entering the hall, one team with one
gentleman and one security asked me to handover my mobile, cigarettes, my
lighter, pens, watch, purse and put them in a pouch. I got peeved of being deprived
of things, which are my constant accompaniment and asked the gentleman whether
he also wants my shirt, trouser and the undergarments too. He looked even more
peeved at my suggestion that these apparels can be of great assistance in
adopting to unfair means and therefore the candidates should be asked to shed
them too.
My daughter was nearby in the queue of the
female candidates and I was not talking particularly sotto voce. So I saw her
glaring at me and mouthing instructions not exactly a daughter gives her father
rather it is the other way round asking me to shut my trap.
The gentleman refused to take my suggestion
and I made it to the hall fully attired and found myself sitting across my
daughter. They make you to sit in front of a terminal, a keyboard and a mouse;
the terminal had nothing on the screen only a blue background. There were
cardboard pieces on the sides and on the front to prevent your neighbor looking
at your screen and the person sitting opposite you to talk to you in sign
language or lip-talk with you. So it was a kind of lonely setup where you have
nothing to do but stare at a blue screen.
I tried to shut my eyes and tried to sleep.
It was difficult as people were clamoring around you. So I opened my eye and
started whistling. Now I am not at all great at whistling and whatever comes
out is neither loud nor has any specific tune in it. But the girl who was
sitting across me behind the cardboard in front of me screamed at me that I
should stop. I tried to peer at her through the gaps and found a young girl
whose nerves are clearly taut as the piano string. I told her not to be so high
strung as that will impact her performance but she told me to shut up.
This wait was for almost an hour and after
that there was some fanfare about explaining the way it should be answered etc.
etc. Probably there was a short tutorial also.
The test happened without any event. I missed
singing like I normally do for challenging and interesting problems, while I
was solving the problems lest I am screamed at again. Then it was over and we
all signed off on our screen.
But they won’t let us stand up and let go. We
have to wait. My feet had cramped and I longed for stretching it. So I stood up
and asked permission to visit the restroom. I was denied permission as for some
stupid reason you can’t leave your seat until something God knows what happens.
So I asked whether it was OK if I kind of relieved myself in the hall itself
under my table. That rattled the invigilator guy to some extent. To convince him
further, I took my hands to my zipper and made movements to convince him that
the zipper is about to start its downward motion. He said “OK!! OK! Go!” The
moment I started, few more hands went up and he allowed everyone to visit the
loo. So much for a stupid rule and all you have to do to prove it to be stupid,
you have to put them in a difficult untenable position.
The only downside of all these was my
daughter refused to speak to me during the delicious lunch we had with Chhole bature at a restaurant next door
and complained bitterly to my mother that I was a crack pot and expert in
creating embarrassing situation.
This time I had another point to prove. My
daughter had, against my advice, had enrolled herself in one of the tutorials
for CAT. I had told her it was a stupid proposition and she should know how to
solve the problems from first principles. Solving quant problems by logic, in
my opinion, is the quickest and smartest way. My daughter vehemently disagreed
with me. At home we used to have our competition with my mother as arbitrator
and in most of the cases shortcut formula lost to logic.
I took a look at the shortcut formula given
by the tutorial and was aghast. They ran pages after pages. You needed another
shortcut to remember shortcuts. An example is like this: What is the last digit of 7 to the power of 4007. Shortcut: divide 4007
by 4 and if the remainder is 0 then 1, if 1 then 7, if 2 then 9, if 3 then 3”.
No explanation, no reason as to how such profound wisdom of shortcut has come
by. No mention that the last digit starts repeating as you keep on raising the
power of seven. All these shortcuts said were if this is that, then you do this
otherwise you do that and so on.
They were taking away the beauty of the sums
and turning the students into automatons. If you forget the shortcut in the
exam hall, it is like a short-circuit of a robot. It stops, as it doesn’t know
what to do. It is so mindless. It was
utterly a sham.
I landed with a percentile of 98.92 with a
quant percentile of 99.84. So my brain was working OK without any degeneration
worth mentioning.
Secondly I was glad that my love for logic
and first principles and my support for them are vindicated at least to my
daughter.
My daughter landed with a percentile of 85
and a quant percentile of 75. She gave up the tutorial and started the old
fashioned logic. After couple of months she confessed to me that this shortcut
is all bogus and there is no substitute of arithmetic logic and working out
from first principles. Next year she landed a very decent percentile and did
her MBA with brilliant result.
The other thing they keep on telling in these
tutorials that you have to be very quick and you don’t have time. This is also
entirely bogus. If one works steadily and slowly like the proverbial tortoise
or to use a more recent analogy of Robocop in the Robocop movie, you don’t have
any dearth of time. Both the times I never felt I was short of time and the
first time though I had lost twenty-five minutes, I did nit feel the time pressure.
It is another myth.
The Internet sites and the various forums
create an unnecessary panic situation of these examinations. Nobody tells the
kids that if you have a strong fundamental knowledge, a logical bend of mind
and analytical skills, you don’t have to prepare for CAT. You just walk in with
a free mind without any tension and write the exam; have fun while writing it
and you will come out with brilliant result.
The intent of this test is to test who you
are, what your real capability is and not what kind of a zombie a tutorial has
turned you into. So be yourself and walk in with head held high…but
alas….nobody absolutely nobody tells that and in the process our kids are misguided and business worth crores flourish
in the name of these tutorials.
