Escape Velocity

Note: This blog is out of context in as much as the big bang theory is concerned...Its just a short story. Hope u enjoy it...(it was authored by Brian N Ball. I try to communicate the story though there are a few changes as I was unable to recollect the original version of the story)....


Eric was just back from the summer holidays. His internship session was about to begin and he wanted to start it in all seriousness for this was the first time he would be coming face to face with an industry. And not just any industry. It was the space industry –or rather- the research center for astronomical studies. He had it carefully thought through. The industry which he selected was the one he had yearned for all his life. Though now almost a computer science student (his degree was due in four months) he had never given up upon his ambition of wandering the depths of space, of walking on moon, of racing with his friends on Mars. And now the first stage of this big dream was closing in.

He had a penchant for studies and another penchant for applying his knowledge to diverse fields. And the list of these diverse fields was always topped by things –rather any thing- that had even a remote connection with space; a connection which people would not talk about or normally even think of, as it required -in their words- a clumsy crow-barring of the worst kind. In fact, these people some of whom were his best friends often mocked his enthusiasm for connecting every thing with space ridiculing him with their favorite sentence – “Hey Eric! Can you give me your crow-bar? Have to kill a shark.” Others said – “That man is never short of crow-bars. You can take as many as you want and he will never ask you to return ‘em”. But his enthusiasm never dwindled and in fact he found a way to stop these comments when he got interested in real shark-hunting and therefore bough a crow-bar. And from then on when anyone asked him for a crow-bar he would start giving them the real thing –a funny sight- for the person asking for crow-bar would often sulk away embarrassed.

His internship was to start tomorrow and he was busy filling forms for the same when he came across a potentially devastating statement saying that people with weak mitral valves are not allowed to be an astronaut. He would not have taken the statement too seriously had he not seen the statement –only one in a hundred thousands has a mitral valve which can withstand the acceleration when one is propelled to space. He got worried and talked to his friends about it. They said “You need not be worried. Why go to space? You are a computer engineer man. You can analyze the data from the earth itself.” “But no” said Eric, “Being there is different”.

“In which sense”

“You will never know”. He replied.

"Okay then, let’s hope the best for the test tomorrow.” They advised. “Or hey champ! Cheer up. If the medicos open their mouth you show them your crow-bar”. Saying so, they burst out laughing. Fuming, Eric left the place convinced that no good would come out of this discussion and he had better wait for the test which he would perhaps, if he had any luck (though he knew he had none) pass. The D-day duly arrived. He was tested and he was sent a letter of regret. How he hated it! The very sight of it took his breath away. He was furious on God, on friends, on parents, on society for reasons he could not fully understand. Hypnotically, he moved to pick up his belongings thinking to go out on a hunt. He picked up his crow-bar. Yes, its time to kill sharks. He was moving past the Proctor-House when he heard him talking to the Warden, “Yes the boy had a real bad luck. If only, we could help him.”

“You know you cannot. I mean, after all it’s about the body machinery. Right? The boy would do better if he would focus on ridding himself of this weakness”, said the warden.

“And what is that supposed to mean? Should he consider a heart-transplant? Eh” asked the proctor.

“No, no. I actually meant maybe there is some other solution around. Maybe he should kind of break-in. There are, I believe always some solutions to all our problems around us. One just needs to look harder when the situation gets more stipulative. “ Clarified the warden.

“And what solution do you find” enquired the proctor.

“Well it’s the boy’s story and he should better think about it” replied the warden.

In the meantime Eric who had accidentally chanced upon this conversation determined to do something about his only dream –of a space travel. He kept listening to this conversation and when he finally moved, he gathered that there was a rocket launch scheduled today. The rocket would go to the moon. And it would transport some of the leading astronomers to the satellite. Not that he did not know this earlier. It was in the papers all the time. But he had forgot it all after that devastating interview today which seemed to have been an year ago, though hardly two hours had passed since.

But now he was a man with a purpose. He planned it –or rather he thought he did. He would be sneaking into the rocket. How would he pull this off, he was not sure. But that he would was sure. He moved to the launch site as one of the spectators, as they were allowed on the launching grounds. But to move on, he would need an access code. And there would be extensive checking with all those cameras and God only knows which other kinds of instruments. Then he hit upon a solution to this dilemma. He would make a run for it once the launch procedures were underway. If he succeeded, he would simply shut himself up in a room where people normally are not supposed to go during the launch –the cleaner room. Every rocket has a cleaner room where oxygen cylinders are stored at a sub-zero temperature. In fact the temperature is so low that you find liquefied oxygen. This serves a double purpose. When the rocket is scheduled to take off this oxygen so released and then exposed to low pressure and a considerably high temperature, due to an initiated combustion, rapidly expands and supports further combustion. Also it allows proper oxygen supply for the astronauts inside the rocket.

Once he was inside this room –when launch procedures would be about to start, Eric thought, he could be on the journey to moon safely. Safely? He mused. He may die of mitral valve problems. But it did not matter. He was ready to pay the price. He may not die after all. And why not try this solution? For, once he was inside the cleaner room, he could as well start oxygen leakage. For fear of cold oxygen, nobody would come inside the room. Yes, this was it –this was his salvation, his solution. Nobody had ever tried the cleaner room before. So, he could rest in peace with his thoughts that security controls for those inside the rocket to go into the cleaner room would be lax.

And when the launch hour ticked near, a menacingly near at one hour before launch, he dashed for the rocket. Dodging some guards, and oh, in fact dressed as a guard himself. (Which he had done after over-powering one and making him unconscious in the process)

He ran into the cleaner room, shutting it close after him. No one noticed. He was glad though his heart continued at a pace which rivaled the fastest race horses he could imagine. And then, the COUNTDOWN!!!

Off, the rocket, was about to take. “Oh, my mitral valve” Eric panicked. Suddenly he heard footsteps outside. Did they know he was in? Will they drive him out? Hell, he had not even cared for his life to see this moment. In desperation he crow-barred open one of the oxygen cylinders and was suddenly drenched in an outpouring of cold oxygen. Imagine being exposed to the coldest thing you can imagine and imagine bathing in a sea of that thing. Even that thought would not give you the shivers which did not last more than five seconds for Eric which were given to him by cold oxygen at -230 degrees Centigrade. The shivers received from an exposure to immediately cold environment can be fatal, so our body shuts itself in that case in a matter of seconds. But those shivers are so gruesome that you cannot have even seen them in movies or documentaries; they can only be asymptotically imagined. Eric knew end was close. And before going unconscious he could hear 3…2….1….0..lift-off.

When he opened his eyes he found himself in a place where he felt light and had a strange happy feeling. Was this heaven? After all he was dead after bathing in cold oxygen. And he was happy, so hell was ruled out. Therefore, going by logic it was heaven. Or was it? When he started moving around he could see a cratered surface stretching for miles and miles around him. He asked himself aloud “Does God leave you in your most cherished place after you die”.

Suddenly he heard a woman “You are not dead, you fool. But you sure would have had I not gone inside the cleaner room in time. We know the story. You are Eric. You wanted to go to Moon and you are here with us. But I must say your solution to mitral valve problem was mind blowing”.

“Eh.” Eric asked “I never solved that”.

“Ow..We thought that you knew that cold oxygen would slow your heartbeat considerably so that escape velocity acceleration does not hasten your heartbeat to a heart-bursting rate. At any cost, your solution was nice and you should know that you have got a bigger fan following on earth than we astronauts do now. They say –the age of dare has not died. It has been restarted through your rash though I must admit bold steps.”

“Do I stay” Eric asked in a fearful voice.

Laughing, the woman replied “Oh yes! You do. Or what do you think. Would we call our mission back once we are here? Though I must say your going back to earth will involve the same procedure, an exposure to ultra-cool oxygen. That’s quite a way to thwart escape velocity acceleration. And it also has inspired a generation to break free of their limitations as they too rise breaking those bondages at an escape velocity…Adventure Continues”.

A Universe, a big-bang

The story and history of big-bang model of universe is in itself a story rich with human travesties an triumphs. The story involves some theologists, some theorists, some experimenters and some mavericks.

I will be touching very briefly upon the work of these giants(for i cannot do better) as i take you on a tour of big-bang. However, dear reader, i warn you that you read this blog at your own risk because to a certain extent it draws heavily from the material my brain sucled in uniterrupted gulps from the wonderful book on big bang by simon singh. But let me make myself very clear "i cannot better a simon singh."

So with the above in my mind and with me having paid credit where credit is due we ponder over the following questions in silence for a few moments " How can one be sure of this model? why is this theory held as the chalice of modern science? who were the scientists who fought to bring acceptance to this unorthodox theory?"

There are obviously many other questions you can add to the list and we will try tackling most of them. At present the approach which seems only fitting to me, is a historical one. Lets ask ourselves "How could one actually believe that the earth was round"...

This is what i call the tragedy of the situation. In fact, how surprising the notion of round earth seem to us all in our early life!!! But once you get used to it, the trouble begins. Without any proper explanation staring in face this is nothing more than a burdened-but-real-give-in of our minds to scientific progress.

Perhaps the recent fight over Pluto's planat-ic (not platonic!!) status illustrates a case in point. Pluto is a planet if scientists believe so...otherwise its not. The blatant truth is NASA is itself divided among those who say Pluto is a planet and those who say it ain't.

I by no means happen to know whatPluto actually is and by no means do i proclaim to know what truth will emerge after a heated scientific debate. But i know enough to comment on philosophy of good science. In good science, like in any good detective novel, a fact which amazes most of the readers, in most cases, leaves other equally dumbsturck.

In other words whats brain-storming for you is brainstorming for me and usually the vice-versa also holds true.

But, with a round-earth, i believe things differ. We wonder equally and passionately about how earth could be round when kids but when we see satelite photos and other high distance ultra quality online-streaming, we know different.

The story of how roundness of earth was established, sings the unrivalled glory of human victory over human traditionalism. It begins with a Polish named Nikola Copernika. He is better known as - Copernicus.


Copernicus was able to "see" the earth's images with pure thought experiments and aided by sheer logic. That logic was deveoped in Greece, polished in Arabic countries and developed formally from its torn parts into a coherent system by Copernicus.

Long back, Aristotle had commented that the earth is flat and is the centre of the universe around which other planets and sun move in circles. To those of you who think gravitation was not a big idea, it seems best to let you know that at this point of time the falling down of objects to earth was a fact readily explained by earth's centrality.

However, Aristoragus, a contemporary of Aristotle, saw a problem. He knew that earth was the centre of the universe - thats okay so far. He expected everything to move around the earth in perfect circles - thats okay. What was not okay, was the fact that planets close to earth -mars and venus- moved in a strange way. They seemed to be exhibiting retrograde motion

This horrible name is understood quite simply. Actually this motion is what you can expect to see if you are watching a object cutting a circular path nearby. (the object is not circling you but circling something different. In case the object were to circle you, you will see uniformity in its motion. It will never speed up or slow down.)

But this is what Mars and Venus did. And if Aristogarus was thinking along the right direction (which he was) probably earth and mars were both cutting circles. Those circles could be around anything (not necessarily same). However, this idea was rejected, slayed by hypothesis of famed Aristotle. Still there were some who held this idea in a serious vein until they met Plato and his epicyles.

Whose fascination!!!

In what follows, (so it has already begun) the readers of this blog (if any) will, or at least should, bein to appreciate if they are not doing it already - the power of a fascination, that lasts. The first obvious question is - which fascination. It is needless to say that other questions like whose Fascination, why fascination follow in the first place.

But since i decided to write about a generic fascination, i named this topic as whose fascination and not which fascination. Note again- the answer to whose fascination is the fascination of the mass.

Having answered the second question, its time to tacle the others; or wait- is it? "Fascination of the mass" - does not that thing deserve a little elaboration? Since i feel that it does, i delve into it.

Our lives are dictated by mostly a desire to find meaning. It is fuelled by a sense of making sense out of what we do and our surroundings/environment does upon us. A simple action-reaction pair. So the fascination which lasts, if it is to be fascination of the mass, it needs to address these basic philosphical questions. what questions? Questions infact related with our action-reaction system and thus connected with our surroundings.

What can be the answer? This is interetingly the first question...Which fascination? and the answer is science...A universe. A big-bang...A theory..A reality...Creation...Miracle..It is this sense of human achievement which i will be detailing more upon in my future blogs. The human history sings this single basic theme. Everybody forms his own theories of being. Not that this is wrong. this is what one must do or else he will be no better than a stone. But taking into the accoun the bewilderment, excitement and tragedy which surrounds one of the world's greatest discoveries, i feel it is imperative that we look down the tunnel created to understand self by the giants of human race...A tunnel we need to look into..A tunnel we need to get fascinated by...A tunnel which tells - why fascination.
