The magical wonderland of Railways

The most efficient way to experience India, if time happens to be a scarce resource is to hop on to a train, those which take three days to go from the source to the destination. A microcosm of the entire nation is duly represented in those 20 odd coaches. I am not talking about those AC coaches, which I believe are used only by snobs, but the more proletarian sleeper class. You see families, mother trying to control their kids, teenagers acting as if they do not give a damn, single travellers who mainly try to stay out of the way, bunch of college kids generating noise enough to derail the train, old people annoyed by the constant shrieks and whinnies of the aforementioned college students, hawkers trying to sell their wares and the mandatory “Pardesi, pardesi, jaana nahi” croon by beggars trying to make a living. All in a couple of days. It is an interesting experiment which a train puts people through every day. The initial suspicion of your fellow passengers, followed by the awkward and stuttered conversation and by the end of the journey, more often than not, you would have told your entire life story, your fears, joys and sorrows, while listening with interest-feigned or otherwise of their story. I believe many life changing decisions can be made when you talk to strangers, who hold an impartial view of what you are and what you do in life. I yearn for those days – when life was slower and flights were out of reach monetarily and the only way to travel were these trains.

My father worked in a bank and that meant only one thing-Transfers. I have had more than a fair share of travelling by trains with huge suitcases carrying our clothes and other worldly belongings. I was a slow kid – I started talking around four and since then I have never stopped. My dad used to joke that for four years, they were trying to make me talk. Since then they have been trying their best to make me stop, albeit unsuccessfully, of course. Once I was travelling with my mother and uncle to Bombay from Bangalore. Bothered by my incessant questioning about every train which used to pass us by and mainly to shut me up, my uncle bought me a railway timetable. Ever since then, I loved trains. Or rather loved railway timetables. Almost every afternoon after returning from school, I spent hours pouring over the book, imagining myself as a tour guide planning a trip for imaginary foreigners, while my mother was busy with her afternoon siesta. For a year or two, my aim in life was to become a guide. Places like Sawai Madhopur, Jalpaiguri, Guntakal – places which no 5th standard kid should know were at the tip of my tongue for they were major junctions. Some places like Kharagpur known for its long platform, Bhawani Mandal – a station half of which is in Rajasthan, half in Madhya Pradesh became some of the important tourist destinations in my mind. My house in Ahmedabad as well as in this small village near Hospet called Hulgi used to overlook the railway track. Countless afternoons were spent with me counting the number of bogies on the goods train. During Kargil war, it was the number of jeeps on the train meant for transportation to the front. There ought to exist some special relation between me and the train. For gods sake, come to think of it, the house I currently live in, in Bangalore is right next to a railway track.

Thanks to the tyranny of the likes of DDLJ, Jab We Met, Saathiya and hordes of other movies which I grew up watching, the notion that it is mandatory to meet some one interesting on a journey is ingrained in my sub-conscious brain. Everytime I take a train from Bangalore to Chennai or vice-versa, I get into the train expecting that I will meet “interesting people” and get aquainted with them and well, you know…Everytime I take a train from Bangalore to Chennai or vice-versa, my seat is always next to an old couple travelling with their grandchildren. Usually it is a 8 year old kid. I generally like kids, but I loathe kids of this particular age. I sometimes wish that kids of this generation weren’t introduced to the marvels of modern technology bringing with it the attention deficiency, so that I can just buy them a railway timetable, introducing them to that magical wonderland. Of course, it would also shut them up for sometime at the least.

Now that I am at crossroads over what I should do, I can’t help but wonder how my life would have panned out, if I had been a tour guide.

The perfect e-book reader configuration

One among the innumerable joys of the final year are those long breaks you get when you have finished the work assigned in the project and you are waiting for the review from the professor. The minimum duration of these breaks is 3 days and depending on your luck may extend upto a week. So, that can imply only one thing – read books. I was a fanatical reader before 10th standard, finishing at the least four books in a week. Though, I must confess most of them were Hardy Boys or The Three Investigators series of books. Ah, 10th standard. Read now and your life will be set, they said. Then pre-university. Read for 12th/JEE/AIEEE/CET and your life will be set, they said. The story didn’t change once I got into IIT. In between all these hullaboo I gradually gave up reading books other than my textbooks. All my novels were kept out of sight in some almirah. Thankfully, one of them – Midnight’s Children by Salman Rushdie, escaped the attention of my parents. I used to sneak out the book when alone and read it. Till date it is my favourite book and I think I have read it half a dozen times.

After coming to IIT, in between those innumerable assignments, I could hardly find time to pick up a book. This year though, is different. Over the past few months my reading frequency has picked up and I am back into the groove of finishing a book at an average of one book a week, a nice mix of fiction and non-fiction. To list the books,

  1. Guns, Germs and Steel by Jared Diamond
  2. The Prestige by Christopher Priest
  3. God of Small Things by Arundathi Roy
  4. The Tipping Point by Malcolm Gladwell
  5. The Argumentative Indian by Amartya Sen
  6. India After Gandhi by Ramachandra Guha
  7. Bartemius-Ring of Solomon by Jonathan Stroud
  8. A Song of Ice and Fire – Game of thrones by George R.R Martin
  9. A Song of Ice and Fire – A Clash of Kings by George R.R Martin
  10. A Song of Ice and FireA Storm of Swords by George R.R Martin
  11. Dune by Frank Herbert
  12. Dune Messiah by Frank Herbert
  13. Children of Dune by Frank Herbert
Right now, I am reading the fourth  book of A Song of Ice and Fire-A Feast of Crows on my laptop and a collection of short stories by P.G Wodehouse from a book.  Finally after much experimenting, I have discovered the ideal e-book reading configuration, thanks to which I have been able to read close to 7.5k pages of A Song of Ice and Fire series.  Calibre E-book Reader along with Artha thesaurus on the side with a black background so that I don’t get too distracted. Super Effective it is.  :-)

Null Hypothesis, Astrology and Cargo Sciences

Recently, I came across this particular article in ToI.  After reading the article, I chanced upon the comments section.  I was quite surprised to see that most of the readers have accused Dr. Venkatraman Ramakrishnan of being an idiot, moron, a terrorist, not respecting Indian culture and quite a few have gone berserk with demands to withdraw Nobel Prize.  A couple of comments show surprise by the fact that he doesn’t believe in astrology inspite of being a Nobel Laureate in Signs.    Fine, I made up the last line. :P

Anyway the main question is how do you test for the credibility of something like astrology, existence of God and other abstract things which is militantly supported by more than a billion people?  It may be true that astrology lacks scientific evidence but there maybe, just maybe an iota of truth in it.  Maybe it is not yet good enough to be called Science.  What if the astrological “principles” are sort of pointing in the correct direction but we are not able to grasp or make a breakthrough?  The problem is that if a person dare says a word against astrology, the entire populace of India seems to find trolling an enjoyable idea.  It is difficult to argue with people who weave stories about how astrology predicted one particular event in the life of one particular person.  This is where the beautiful concept of Null Hypothesis can make the difference.

The main idea of the Null Hypothesis is that you assume a certain stance unless proven otherwise.  Or to put in more compact terms, the default position.   To demonstrate the idea of Null Hypothesis, let me take an example of a random coin toss experiment.  I assume that the default position is that the coin is unbiased, that is, there is as much chance of getting heads as there is of getting tails.  So, I toss the coin 10 times.  Now the expected number of heads that I should get is 5, assuming independent trials.  But what if I get 7 heads and 3 tails?  Can I declare “confidently” that the coin is biased?  Not really.  What if I toss the coin 100 times and I get 70 heads?  Just maybe.  What if I toss the coin 1000 times and I get heads 700 times?  Now it is more apparent that the coin is biased, but is it biased (0.65,0.35) or (0.70, 0.30)?  I do not know that yet.  I need to conduct more experiments.  Of course this is just the property of Law of Large Numbers.  The question is how many trials do I require before being say “95% confident” that the coin is biased?  There is a bit of mathematics involved in it, which I will not go into the details of.   So let me assume that in I need 70 trials out of 100 to turn up heads to declare that with 95% confidence the coin is biased.  This is termed as “Rejecting the Null Hypothesis with 95% confidence”.

Now that the tutorial on Null hypothesis is over, let’s see what can be done regarding astrology.  The main problem with astrology is that there are so many contentions regarding the rules that it becomes difficult to have a comprehensive test.  So, a manual regarding the rules of astrology needs to be prepared such that there are no evident contradictions.  If the argument is that astrology is too vast a subject to be put down into a manual, let them take a small part of it, say zodiac sign and one dominant characteristic of the person belonging to that sign.  Now we need to prove that “most” of the times the Zodiac signs and the trait in question are predictable.  So, it becomes a binary random variable akin to the coin toss experiment – heads if the person has the same traits as the one predicted by the Zodiac sign, tails otherwise.  One obvious problem is what the Null hypothesis should be.  If my thesis is that the theory of zodiac sign is truly random, we take (0.5,0.5) as the null hypothesis.  If I believe that it predicts the behaviour 60% of the times, my null hypothesis would be (0.6,0.4).

Either way, it should be an interesting experiment.  I wonder about the technical feasibility of such a project.  Well, if not the entire nation, maybe at a smaller scale inside the insti campus.

Any views? :)

The Running Chronicles – I

And yet another year dawns upon me bringing with it the queries of life, the questions about those nauseating highs and dung-filled lows, the tyranny of seldom-kept resolutions and the unwelcome associated guilt that hits you hard when they are broken bringing the entire exercise to naught.  Anyway, coming to the point I have had a habit of making resolutions, a miniscule of them attainable, most being as a meme would suggest,

The common part about all these resolutions is that I have succeeded in keeping none of them.  This year I have come to the conclusion that I need to become healthy, a resolution bordering on the “IMPOSSIBRU”.

After being unable to wake up in the morning for two days on the trot, I am almost on the verge of giving up. Anyway, Adhok after paining me enough has made me register for the 10k Auroville run on February 12th. Right now, I can jog a maximum of 1.1 kms at a stretch before I run out of breath. From my hostel till Elec Department. Tomorrow, my training schedule states I have to run 4kms. Sigh. Keeping my fingers crossed. The main purpose of recording this here is so that I can shame myself into running if I ever stop again.

PS: After much contemplation, I have decided that I should increase my blogging frequency, given that I hardly have anything to do this semester.   Around 5 posts per month is my current aim.  Let’s see how things pan out.

Update: Finally. Jogged 4kms. Or rather jogged for 3.3kms and walked 0.7kms. From hostel till Velachery gate continuously. Walked from there till BT-department-turning. Jogged again till the hostel. I am quite sure that I will have sore legs today. Day after tomorrow, I am supposed to run 5.2kms. OMAIGAWD.
