It's been some quite some time since I posted something .
Yesterday I wwent to see the malayalam movie ,Pachamarathanalil. and starredby Srinivasan .
The story tells of the kidnap of a cartoonist's little girl . The movie is dotted with flashbacks which tend to get a little too stretched . The storyline is quite twisted with communal violence also being pulled in . Overall it's a movie worth watching and in a scale of 0 to 10 , I would give it a 6.5 .(Not many movies will go past 8 in my rating). See it if you like to do some serious thinking . Cheers :)
PS: Dunno why but I like posting a "PS" . Even if you keenly follow the movie,you would have to be a Sherlock Holmes to predict the storyline in the given time .

Speed of Light
Most people usually think of the speed of light as being really fast. It's 671 million miles per hour. That seems tantalizingly zippy if you're caught in traffic.
However, once you think about the speed of light within the context of our solar system, it starts to seem unimpressive.
It takes about 1.3 seconds for light or radio waves to reach us from the Moon, which really isn't all that far away (it's only 20 times farther away than Australia is to the United States). This was an issue during the Apollo space program, because due to the round trip time of the radio signals, NASA had to wait about three seconds to hear the answer to every question they asked the astronauts.
When Mars is closest to the Earth, it takes light three minutes to travel between the two planets. If you asked a question to an astronaut on Mars, you'd have to wait at least six minutes for an answer, and Mars is usually a lot farther away than that. At its greatest distance, you'd have to wait 42 minutes, or even longer if the astronaut is watching Gilmore Girls. In the future, there will be no such thing as sending an "instant message" to your friends on the Mars base. There also won't be any day trading or free pizza delivery.
The Voyager 1 spacecraft was launched only 29 years ago. It's currently the farthest away from the Earth of any man-made object. In just a short amount of time, this spacecraft, designed by primitive 1970's-era engineers, many of whom were wearing corduroy bell bottoms, has managed to travel so far away from the Earth that it takes radio signals travelling at the speed of light 14 hours to reach it.
I am not making this up. An object that was recently built by people is now far enough away that if you could travel to it at the speed of light, for the in-flight movie you could watch the original director's cut of Water World four times, break for a dinner, and then watch Ishtar before having to put your tray in its upright position.
Light takes four and half years to travel to the nearest star (other than the Sun), 100,000 years to travel across the width of the galaxy, and 100 billion years to travel across the observable Universe.
The speed of light isn't all that fast. Get over it.
I just may have missed one teeny weeny thing...
I forgot to take into account time dilation.
Thankfully, you actually wouldn't have to wait through all those boring movies. In the crazy world of Einstein's theory of relativity, if you travelled close to the speed of light, very little time would appear to pass from your point of view, even though time would pass normally for everyone else, and they would have to do all the waiting around. The upshot of this is that if you travelled at near-light speeds to the nearest star and back, only a few seconds would seem to pass, but when you returned to the spaceport on Earth, you would still be responsible for nine years of parking fees.
Sleep
If you were to live deep inside a cave, with no exposure to the outside world, eventually you would start sleeping roughly every 24 hours and 18 minutes, instead of exactly every 24 hours.
Under normal circumstances, our eyes sense light from the Sun, and our brains adjust to the standard 24 hour day, but we'd really always like to sleep that extra 18 minutes. Why is that? Scientists don't really know, but maybe it explains why everyone is so crabby all the time.
Some completely blind people, who sense no light at all, naturally live on a 24 hour, 18 minute day, and slowly march their schedule around the clock, out of phase with everybody else. I'm speaking from personal experience when I say that it's pretty annoying when you have a blind neighbor who mows his lawn in the middle of the night.
Our built-in tendency to live on a 24 hour, 18 minute day might seem to make sense if that was how long days were in the distant past, and the length of each day has been slowly speeding up. However, exactly the opposite is occurring. The length of each day has been gradually increasing, as the rotation of the Earth slows down because of the Moon's tidal forces. Half a billion years ago, days were 22 hours long. Four and a half billion years ago, they were six hours long. This didn't allow for a lot of variety in the television programming schedule.
A need for a longer day might also make sense if we were all from Mars. (We're not. Most of us are not. Let's just say that all the important people you know are not. If you don't already know that you are, you're not. It's best if you don't bring this up with your parents. Forget I mentioned any of this.) On Mars, each day is 24 hours and 39 minutes long. Scientists working on the Spirit and Opportunity Mars rover projects initially lived on a schedule based on Mars days, because the solar-powered rovers could only operate during daytime on Mars. The scientists wore special Mars watches so they'd know what time it was there. After a few months of this, and always sleeping weird hours, they were all pretty grumpy. Eventually they switched to a more practical, Earth-based schedule.
Sleeping in one continuous block during the night is an extremely recent development. Humans only started doing this when artificial lighting become readily available, and it was easier for everybody to stay up late. Before that, people tended to sleep in multiple chunks throughout the night, separated by periods of activity. Presumably, they would use this time to make trips to the ice box or watch crude infomercials performed by nocturnal travelling minstrels, which were quite popular during the Renaissance.
Three Horizons
If you're standing on the edge of the beach, the ocean looks enormous, as if it stretches off forever. However, because of the Earth's curvature, the horizon is only three miles away (a little farther, if you're wearing platform shoes, or stilts and a clown costume). You can really only see a very small amount of the ocean. The Pacific Ocean, for example, is roughly nine thousand miles across.
When you look up at the night sky, it's fun to try to imagine how huge our galaxy is. It contains at least two hundred billion stars. However, because most of the stars are very dim and far away, you can usually only see several hundred of them without a telescope. The farthest star you can see is about a thousand light years away, and our galaxy is a hundred times larger than that. In short, you can't see squat. And if you live in a big city with lots of light pollution, you might as well have a paper bag over your head with a rotting fish in it. That's how much of our galaxy you can see.
What I am really saying here is that as far as I'm concerned, you're fully justified in staying at home on the sofa, playing video games, eating ice cream, and getting super fat. If you were to bother to go outside, then even under the most ideal conditions, you wouldn't get to see very much of anything anyway.
I've decided to post some cool science facts which everyone especially intellectuals will have a great time reading.Here goes the first one.....
OK here is the deal with the space shuttle. It has three rocket engines in the back, but there's absolutely no room inside for all the fuel it needs to launch itself up into space. All of that fuel is stored outside the shuttle, in the big brown cylinder, called the external tank.
The tank containing all the rocket fuel weighs seven times more than the space shuttle itself! That's a lot of really heavy fuel, and the space shuttle engines aren't quite strong enough to push the combined weight of the shuttle and the big bloated external tank up off the ground.
That's what the two long white solid rocket boosters strapped onto the sides of the external tank are for. They lift the tank! Fortunately, it was not necessary to strap an infinite series of smaller and smaller rockets to the sides of the solid rocket boosters.
It is not widely known that just behind the main flight deck of the space shuttle is a small Starbucks adapted for use in zero gravity.
Pi
Pi
Leonardo Fibonacci discovered a simple numerical series that is the foundation for an incredible mathematical relationship behind phi.
Starting with 0 and 1, each new number in the series is simply the sum of the two before it.
0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144, . . .
The ratio of each successive pair of numbers in the series approximates phi (1.618. . .) , as 5 divided by 3 is 1.666..., and 8 divided by 5 is 1.60.
The number pi is the ratio between the circumference of a circle and its diameter. It's approximately equal to 3.14159265, although the digits go on forever.
Pi is evident in many situations in nature. See here.
Some mathematicians are obsessed with computing pi to more and more digits. In the year 1610, a German mathematician computed pi to 35 digits. In 1789, a Slovene mathematician computed pi to 140 digits. This was all done by hand, in poorly heated houses.
An English amateur mathematician spent 20 years calculating pi to 707 digits, finishing in 1873. 71 years later, it was discovered that he had made a mistake at the 528th digit, and all the digits following it were wrong.
In 2002, frantic Japanese mathematicians used a supercomputer to accurately compute pi to 1,241,100,000,000 digits.
Based on all this effort, you might assume that it'd be useful to know a trillion digits of pi. However, if you had a circle the size of the observable universe, and you wanted to compute its circumference with an accuracy equal to the size of a proton, the number of digits of pi that you'd need is only 43.
Either mathematicians are totally crazy, or they're planning ahead for a time when the survival of humanity will depend on the ability to construct extremely large, accurate circles

Welcome to my own blog guys.
This is my first post .
Hope to start big. Now let's see.........aahh yes
Spent my 3 hrs watching IPL CSK v/s KXI.
Well not much of a wasted time coz I got the result I wanted.
You may have guessed who I am routing for ,right. You said it man ,
"CHENNAI SUPERKINGS RULE"
Well , whiling your time away watching cricket (esp when the university exams are just around the corner) has its own err "bad effects" (well mom effects to be precise).
She's all stressed out coz she feels that I am going to do badly in my boards,(not that her fears are baseless......gulp..) Well everyone gets thrown off by the freedom you get when you join college and start your hostel life ...but I kinda forgot why I joined college in the first place(to study of course.......ya well for most people).
To make her feel better I studied hard for 1hr(amazing how much you can take in when you concentrate)
Feeling tired an all . After all its ....WHAAAAAAAAAT 2:49 in the night. Well I blew my hopes of getting up early in the morning (not to catch the worm o'course but to go to church).
Ya well to all those who enjoyed reaading my post , do leave a comment . I'll post maaaaaaaaaaaaaaaany more interesting things & muuuuuuch more insights into my wooooooonderful life.
YAWWWWWWWWWWWN....Oops . Cheers
