Do you Know why IRCTC does not allow you to choose seats? Would you believe that the technical reason behind this is PHYSICS.

Booking a seat in a train is far more different than booking a seat in a theatre.

Theatre is a hall, whereas train is a moving object. So safety concern is very high in trains.

Indian railways ticket booking software is designed in such a way that it will book tickets in a manner that will distribute the load evenly in a train.

Let me take an example to make things more clear : Imagine there are sleeper class coaches in a train numbered S1, S2 S3... S10, and in every coach there are 72 seats.

So when some one first books a ticket, software will assign a seat in the middle coach like S5, middle seat numbered between 30-40, and preferably lower berths (Railways first fills the lower berths than upper one so as to achieve low centre of gravity.)

And the software books seats in such a way that all coaches have uniform passenger distribution and seats are filled starting from the middle seats (36) to seats near the gates i.e 1-2 or 71-72 in order from lower berth to upper.

Railways just want to ensure a proper balance that each coach should have for equal load distribution.

That is why when you book a ticket at the last, you are always allotted an upper berth and a seat numbered around 2-3 or 70, except when you are not taking a seat of someone who has cancelled his/her seat.

What if the railways book tickets randomly ? A train is a moving object which moves around at a speed of around 100km/hr on rails.
So there are a lot of forces and mechanics acting on the train.

Just imagine if S1, S2, S3 are completely full and S5, S6 are completely empty and others are partially full. When the train takes a turn, some coaches face maximum centrifugal force and some minimum, and this creates a high chance of derailment of the train.

This is a very technical aspect, and when brakes are applied there will be different braking forces acting at each of the coaches because of the huge differences in weight of coach, so stability of train becomes an issue again.

I felt that this is a good information worth sharing, as often passengers blame the Railways citing inconvenient seats/ berths allotted to them.

Throughout the history of mankind  there  have  been  many  questions  that have  been  left  unanswered  and  "VONYICH  MANUSCRIPT"  is one  of them. For almost 100 years experts and researchers have tried to solve the mystery behind the manuscript and its content, but none of them succeeded. The numerous theories to unravel the mystery behind this manuscript are contradictory and rang from plausible to adventurous.

The modern  history of the manuscript  began in 1912, when an Italian book collector  and seller  Wilfried voynich" found it in an Italian Jesuit college and carbon dating  proves that the manuscript was first written in the 15th century(between 1404-1438).the manuscript is written in a language unknown to man. There are between fifteen and twenty different letters in the manuscript. The language can be brought in line with European languages, because the average word length is four or five letters. However the language of the manuscript does not correspond with any of the European language because the voynich has no two-letter words or words with more than ten characters.  The only idea anyone has of its origin are the drawings and illustrations found on various pages. Unlike the text, the illustrations can be divided into different sections and can be distinguished as botanical, astronomical, balneological, cosmological, pharmaceutical and chapter with food recipes, And the problem is none of them match with the species of plants , animals and astronomical units known to man. statistical analysis of the text  indicates it was written in a natural language and no flaws were found in the writing which means the person who wrote it had  a very good command over the language and isn’t a hoax. The different illustrations can hardly be related to one topic. Thus, one can possibly say that it is a textbook for magicians, physicians, and astrologers but when it comes to these professions their borders were still blurred 500 years ago. It is hardly illuminating to take look at the astronomical and cosmological sections, which contain pictures that can be identified as the zodiac signs still familiar today. Unfortunately, this observation does not result in further insight into the book. The celestial bodies illustrated in the astronomical section cannot be identified and probably are only figments of imagination or they belong to some other star system (but how the hell can they know about other star systems in fifteen century...this raises some questions which conspiracy theorists link to aliens...aliens). There are two theories worth mentioning about the manuscript. The first one is based on a fact that is known by every cryptologist, that the design of a secure text is longer than the original text. Under this condition, it is possible to hide the original information in the meaningless filler text, then there is only a minimal chance that it will ever be decrypted....but this trick only works when you make meaningless sentences out of known languages, so if that is the case then the author of the book must have known the language used in the manuscript. And the second theory is based on what the conspiracy theorists say. They believe that the manuscript is a encyclopaedia of knowledge given to man by the extra-terrestrials who visited them at the time.
So, question is why would any take such an effort to write a book in a language unknown to others????????  Did the people or the person who wrote the book didn’t want anyone to know about its contents?? does it contain secrets unknown to mankind  like  attaining  immortality or the medicine to cure any disease or interstellar space travel Or does it describe about  the species of another dimension(from another world) or is it a mere hoax as proposed by many theorists. What does the manuscript really contain about?????? These questions still remain unanswered.
