How does the world work?

Hieee!!!
The trouble with blogs is that they show your latest entry first which sorts of turns the thing topsy-turvy. Anyway let it be the way it is.
So I promised to tell you sumthing really amazing last time.Hmm.. The thing is that I recently got a gr8888 book on latest physics precisely “The String Theory”.It is called “ The Elegant Universe” and it is by Brian Greene. This one book promises to change the entire way we look at the Universe.
The basic thing about String Theory is that it says that you have a lower limit on how much you can keep dividing a thing. This fundamental unit of length is the length of one string which turns out to be precisely equal to the Planck constant i.e. 6.634* 10 –34 m.Is not that amazing??

But the basic intuitive flaw that arises is that we can’t comprehend that there can be a lower limit at all. After all you can cut an apple into half and then its half and then its half and on and on upto infinity…

The explanation to some extent can be found in an old Chinese problem. Suppose you want to go from point A to B.You decide to go half the distance first .Then you again cover half the distance left that is you have gone ¾ distance now. So you go on going by half distances everytime and eventually u find out that you can never get to your destination at all as always some distance will be left!!!!!!!!!! So going by this argument how can you even go ½ the initial distance anyway??? So does that mean that you can’t move at all? But people move all the time!! So where is the damn flaw??

The argument vanishes if you assume that you can’t go ½ the distance of a string. Well this is a bit like killing the whole issue by saying that Mother Nature just does not allow you to go beyond the string ? Why though? As to that nobody has a satisfactory explanation.

Still making this simple assumption has far reaching effects .One of the greatest successes of String Theory has been the explanation provided by it on the merger of Relativity and Quantum Mechanics on sub-plank scales. Also it beautifully incorporates the presence of particles like gravitons which are responsible for the force of gravity.

Have you ever thought how it would be like to have a multi-dimensional world???Can u even grasp the meaning of having another dimension? It really defies all imagination!!
So meanwhile ponder on the amazing creativity of this thought and not to forget keep watching out for my blog!!Adieu!!

Hi Again!

Hi!
After a long long time I hit the keyboard again. I hav spent the last one month in heaven it seems!Home was never a more welcome word !!Especially after one year of IIT.

I have been doing just what I please lately. Sleeping, eating sleeping and not to forget sleeping were some of my favourite past times:D:D:D

Well that’s not entirely true actually bcoz you do get bored of sleeping also eventually !Unbeleivable isn’t it:-o But so it is.

So my other pastimes have been watching TV,reading , listening to music,Minesweeper,Dave etc etc.Hey Hip hip hurrah for me I finally managed to reach the 6th level in dave .
You know this antique piece of a comp has developed a strange problem.The monitor goes off in every 15-20 mins .And even stranger is that it comes back on again if you rub the pins at the end of the chord joining it with the CPU ,with a metal object!! Even as I was writing this the monitor went off and came on again when I rubbed the chord using a key.

Well Well Well I know I am deviating from the original purpose of this blog as it was meant to give you a perspective of life at IIT.But come on I am now tooooo lazy to start another blog with another name and all.So just consider that NOW this blog deals with me only :):):)

But I won't bore u all by telling abt only myself as only snobs can do that .This was just a bit of background information to get myself in a writing mood.I shall tell you abt some really
Interesting things that I have recently read and which will radically change the way u look at the world around you and the
Laws of the Universe in general!!!So keep visiting my blog:)
