That mirror.
Amid the absolute darkness.
Nobody knows.
Nobody cares.
There is that nobody.
Laughing at your basic theory,
Turns on the light.
Can you see him through that mirror?

A Time Traveler

Posted: February 11, 2015 in Uncategorized

So deep into your thoughts,
Into the beautiful symphony of the millivolts,
Into the elusive state.
Whatever it is,
Whatever mystery or myth.
Not driven by obsession but desire,
A desire from your free will,
Or perhaps your brainchild, its success.
Not motivation. Not needed.
For a time traveler about to hit the clock.
Good morning. Already.

Doctor? Engineer? Pilot?

Posted: January 27, 2015 in Uncategorized

I like to go camping once in a while to get off the city hustle. Last weekend it was me and few lads I have known long enough to sit around fire. The place where I live, we never have winters, so the bonfire was not treasured as you may like. Given the time of year, it was nevertheless more chilly than usual. Enjoying the warmth, we frivolously indulged into conversation not knowing where it could lead. It just started with the question, “Why are you planning on doing a PhD, Nimesh?”. “I want to become a doctor and an engineer at the same time”, I replied jokingly. Additionally, I recounted on my culture, where elders usually gave blessings during festivals, saying, “Try to become a big person. Try to become either a doctor, an engineer, or a pilot”. For that, I will learn to fly airplanes once I finish my PhD, I laughed out.

Eventually it boiled down to money, life style etc. etc. that one will pass while pursuing PhD instead of a job, which I shall write. Someday.

Right Round

Posted: January 15, 2015 in Uncategorized

Why is the earth revolving round its axis as it rotates around the sun? Newton and Einstein successively deduced gravity to promisingly explain the earth’s rotation around the sun. However, the explanation for our earth’s self rotation (wobbling) is, as of yet, unfounded. It has been like this since the big bang, says science. Possible, yes; convincing, no; given the extreme serendipity. The earth rotating around it’s own, and at such optimal speed is something very critical for our existing. Without this rotation, there would be no life on this blue planet. In fact there would be no blue planet. Half of the earth would become red hot, while the other half would become white, perhaps blue, filled with ice. In simple terms, half of the earth will have day, while the other half will have night, forever. Or perhaps not! Since heat conducts no matter in space, heat from the hot region will flow towards the cold, and the cold part should also become hot in due time. How long would it take though? The hot part might tear away with radiation and the earth might lose its identity by that time. Or the earth might fall into the sun’s pit with the increasing gravity with time. Given the time constraint, will the earth be able to come to thermal equilibrium? Let’s try to find out.

We need to calculate the total heat energy received from the sun against the amount of heat energy required to raise the temperature of the earth per degree celsius. We also have to incorporate the thermal conduction coefficient of the earth to calibrate the heat conduction. The specific heat capacity of the earth is 0.3 Kcal/kg.C, which is the amount of heat energy required to raise the temperature of 1 kilogram of earth by 1 degree celsius. Therefore, for the mass of the earth (5.972E24 kg), the amount of heat energy required to raise it’s temperature by 1 degree will be = 0.3 x 4.184 (calorie to joule) x 1000 x 5.972E24. The total energy required comes out to be 7.496E27 Joules. The total solar heat energy bestowed to the earth in a year is equivalent to 3.85E24 Joules. With this input energy, the rise in temperature of the earth’s surface in a year will be = 3.85E24/7.496E27, equaling to 0.5 milli celsius. Given this condition, it will take ~2000 years for the sun to increase the temperature of the earth by 1 degree, even though we neglected the heat loss to outer space and the not-so-efficient thermal conduction coefficient of the earth. Nevertheless, the earth should be able to come to thermal equilibrium and become all red before vanishing, given its life span.

This idea is only for the sake of thought and is not derived or based on anyone’s previous work. The only thing that led to its invention is this song I am not so much into contemporary music, but this song should get you off your chair as well. It’s not explicit, you can blast it off your speakers. Enjoy.

Where do you look while SIPPING?

Posted: December 31, 2014 in Uncategorized

Yesterday I was invited for a dinner at one of my friend’s house. After devouring the fish appetizer with full swing, we eventually sat for the final meal. The loud and raucous room suddenly turned into a peaceful arena, saturated with a spicy aroma of chicken curry. Everyone was so focused on their dishes, you could hear the next person humming on your side. I am a slow eater and tend to start my food as they become less warm. Patiently watching the steam dissipate, I saw one of my friend, in an inadvertent glance, swallow his full-bodied meal while drinking water. What fascinated me was the way he rolled his eyes while having the cup in his mouth. Before briskly putting the cup down, he surreptitiously looked at everyone’s food again. I was quite amused while my hasty friend was concerned about his chicken curry. Out of curiosity, I observed other people as they drank water from their cup. Where do they look while sipping? Do they look at their food? others food? or inside their cup? Does this mean anything?

As nobody cared to talk over voraciously eating their food, including me, I knew I was not going to be noticed. People gave off their nastied chews not knowing how someone was inappropriately watching them constantly. While I was trying to deduce my earlier friend’s behavior rushing with his food, which I thought as impatient and eager, one of my other friend picked her glass as I begun to capture in slow motion. In contrary to the previous one, she was quite the opposite. She looked at the water inside, it’s all right, and took a brief sip while looking inside the cup. In a very relaxed way, she kept her cup down with pin drop silence. She seemed overly cautious and careful to not let anyone hear the cup off and on, the sound of the drink flowing down her throat, and the new half-spoonful meal she chewed. Perhaps people looking inside their cup are either shy, content or thoughtful I felt. Momentarily, my other friend gave a loud burp, took a pause, and gulped the water watching his own food. As the situation suggested, I’d surmise people looking at their own food are rather unconcerned or carefree.

I was just trying to entertain myself in the process of bringing some fun into a quiet dinner. Do this peculiar behavior of sipping give any information about a person’s nature? How greedy or confidence or rich or poor they are? Is it a habit or a momentary behavior? I’ll leave that for someone else to answer.

Case Of The Pleasing Horn

Posted: May 27, 2014 in Uncategorized

He stayed there for 4 odd seconds.
That cop in the middle of the busy road staring at me.
Then put his head down and crossed the street.
Improperly again.
What must have gone through his mind; I raced through.
Can’t give me a ticket for honking at him.
I smirked.

Aristotle believed that everything in the world was composed of four basic elements – earth, water, fire and air. He also suggested the nature of forces that acted upon these elements, gravity – which caused earth and water to sink, and levity – which caused fire and air to rise. No matter how primitive and vague his concept was, it is still very consistent with our division of particles of the universe into matter particles and force particles. Aristotle believed that matter particles were continuous and there was no stopping point at which matter could be divided further. Democritus and Leucippus on the other hand, considered matter to be discrete and being composed of small units called atom (atom in greek means indivisible).

For centuries there was no hard evidence to prove whether matter was continuous or discrete. In 1803, a British physicist John Dalton came up with an idea that chemical compounds always combining in certain proportions could be the reason of atoms reacting with each other in numbers to form units called molecules. By 1897, another British physicist, J. J. Thomson discovered the existence of negative charge in matter particles with his cathode ray tube experiment. Even though it was apparent at this point that atom, indeed, was not the smallest unit, the structure of atom was still vague as no one could comprehend the origin of such negative charge.

One of the important pieces of physical evidence was provided by Einstein in 1905 in his paper, “On the Movement of Small Particles Suspended in Stationary Liquids Required by the Molecular-Kinetic Theory of Heat”, where he pointed out that what was called Brownian motion could be explained as the effect of atoms of the liquid colliding with the dust particles. Due to his groundbreaking theory on special relativity and photoelectric effect published in the same year 1905, his paper on Brownian motion went largely unnoticed. Later in 1911, another British physicist, Ernest Rutherford corroborated the existence of elementary particles within an atom. From his alpha-particle bombarding experiment, he proposed the existence of nucleus, describing it as a very small and dense region within the atom, and comprising of positive charge – the positive charge was later discovered to be proton having the same magnitude of charge as the electron. After James Chadwick discovery of neutron in 1932, the structure of atom became much more explicit, with proton and neutron forming the nucleus and electron spinning around the nucleus – the solar system model.

An amusing, yet logical feeling that I inadvertently summon while I cogitate over these historical advancements is how little these scientists knew about the particle that make up everything, before 1930. Yet, the most profound and far reaching theories of thermodynamics, relativity, quantum mechanics, in fact the whole of science, were proposed before that date and is still consistent and relevant to this day. The atomic structure, tunneling, discreteness in energy level and existence of degenerate energy state, discreteness of light etc. are all perfectly coherent with quantum mechanics and photoelectric effect and such. So if these theory deem to be true, are the experiments performed to verify them being influenced by our prior knowledge or do we really don’t need to know much to understand and revolutionize the world?

Special theory of relativity is an extension of Galilean relativity. In simple, Galilean relativity states that if you are in an object that is moving at a constant speed, you won’t be able to tell whether you’re at rest or motion. For instance, we don’t feel any motion sitting in a planet that is rotating around the sun at a speed of 30km/sec. Einstein special theory of relativity takes the relativity perspective to one step forward by assuming time to vary like speed based on observer. Time is therefore no longer constant in special relativity. Some famous corollaries of this theory include the feasibility of time machine and time travel, a yard stick that would contract and expand depending on its velocity etc. This is the best video explaining ‘Einstein Theory of Relativity’ that I’ve seen in the web. Enjoy the video, it’s worth the time:

Do you ever ponder upon the reason behind dreaming, how it develops or even what it really is or means? Not to mention how it gets so fascinating and surreal? Real, scary, living up fantasies and sometimes quite mysterious than day to day experience. Well! that’s dream, and that’s something no one seems interested even though no one knows much about it. One of the other thing that confounds me is the slowing down of time while dreaming. There are so many incidents that occur that your brain processes but in a relatively short time. Practically, your brain is working many times faster when you are dreaming than when you are conscious, and the reason is pretty simple – as most of our senses get to rest, brain gets all the munchies to work.

The aspect that really fascinates me is the fact how I can put myself in so many places and do multiple things in a relatively short time. A real incident that happened to me last week when I was traveling with two of my friends from Boca Raton to Miami, I felt asleep on the way in the backseat of the car. I had this crazy dream of winning the lottery of 350 million, which probably got into the mix from seeing the lottery ad in a hoarding board on the way. I received the full money as there is no tax cut in dreams (pun). But for some reasons which I could not recall, I wasn’t allowed to spend the money. I woke up and asked my friends to stop by a nearby store and purchase the lottery ticket thinking I might win. NOT! Dreams can be false and are most often so in my case. But that’s not the point I want to get into. I knew I had been dreaming for at most 7 minutes because the car clock, right in front of my eye, had changed from 9:35 to 9:42 before something woke me up. In these approx 7 minutes – I bought the lottery, won the lottery, got the money, got featured in the TV, tried to use the money, and wasn’t able to. It all felt so real like a movie and the series of events were recollection of few days from buying the ticket. Life moved so much faster in those 7 minutes.

Everyone must have experienced free falls while dreaming – falling off a cliff or a building and never reaching the bottom, so scary yet so real. You never reach the ground! Scientist define dream to be just a recollection of past events and experience, which however seem to contradict with the free fall experience which many people like me do not have real life experience on. To justify the claim, they assert the brain to be simulating such fall from real life experience of jumps and falls and surmising it to a higher extent. I am no scholar and it might be true, but I happen to be a hard skeptic, and I for one don’t believe in such unfounded assertion. How can we know much about dream when we know so little about the brain itself! What I believe that might be true is the eye and other senses stifling our brain to process things differently thereby confining ourselves to this inadequate 3 dimensional world. Or may be it’s the world itself that confines our brain and limits it’s potential. Will we be able to think faster if we were in a different world driven by different physical parameters, different gravitation force, different speed, different constraints? May be. May be all we need to do to explore the universe and other dimension is just close the eye for few minutes and rest all our senses and get the brain into full action.
