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 success, your brainchild.
Not motivation, you don’t need.
You’re just a time traveler about to hit the clock.
Good morning. Already.
So deep into your thoughts,
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.
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 https://www.youtube.com/watch?v=CcCw1ggftuQ. 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.
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.
The WordPress.com stats helper monkeys prepared a 2014 annual report for this blog.
Here’s an excerpt:
A San Francisco cable car holds 60 people. This blog was viewed about 1,000 times in 2014. If it were a cable car, it would take about 17 trips to carry that many people.
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.
What must have gone through his mind; I raced through.
Can’t give me a ticket for honking at him.
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 believe that your actions have already been fixed? In fact whatever you do in future is bound to happen irrespective of your will. For instance you are reading this article because you were destined to read it, and I wrote it because that was my destiny as well. The idea seems quite bizarre, but there’s a majority of physicists that believe it’s true. Since everything is made up of the same elementary particles just with different composition and concentration, the behavior of every matter and the way in which everything occurs must be explicable and defined. Therefore what you do, in fact whatever happens in this world – the atomic bomb, the world war, advent of computers, airplanes etc. has already been scripted 13 billion years ago, right at the time of the big bang.
Well if this happens to be true, things and cases it ensues can get quite complicated. One cannot be blamed (or accredited) for his actions, as he was destined to do it. For instance, a murderer or criminal should not be held responsible for the tragedy and must be exonerated from his crimes if this is true. Now the world can be a real disturbing place to live in. This created a huge contention among scientists of the 19th century. Einstein opined that a person should be no matter held responsible for his/her actions no matter bad or good, and a criminal should be punished accordingly. He said it was necessary to do so in order to maintain stability in the world. Otherwise, the world would run into riots.
This entails an interesting relation between religion and science. Now as religion, indeed every religion, believe in destiny and fate, and god deciding all the events and happenings that take place in this world – science seems to be justifying it. But with scientific reasoning, of course. Well I’m not an advocate of religion trying to impress or urge you to believe in it with my hypothesis. Personally, I won’t reject nor believe in the possibility of existence of god. If you ask me, throw me into the agnostic category.
So was Einstein a genius, or just an extremely lucky man to have been chosen to formulate those equations?
