The concurrent election in Odisha just drew to a close and I did an analysis on the results available tentatively. Notice that there is no visible errors here even if I eg adjusted 854 to 850 and so on. If you add up the % figures they add to 100% perfectly — I simply did the calculation and applied no tricks, that means there is some simple pattern in the data which is the reason I made this post.

Finally I am successful in calculating pi value — less than 0.3% error, by using random number generation. Although my computer needs some fixation on its compiler or path definition etc, there are very good online compilers which helps in testing and running c++ codes: try the given link.
Computing the value of pi using std::rand()
Enter number of trials: 10000
Enter number of random (x,y) points per trial: 10
pi = 3.14376 +- 0.00519107
average – exact = 0.00216735
CPU time = 0.004027 secs
Here is the code I found by searching a good deal on the web. Yes I did tinker around but only because my own compiler (Turbo C++ on windows 10, 64 bits) was throwing some exceptions on the included headers.
using namespace std;
double pi_estimate(const unsigned long points) More…

Why often they guard themselves against, the deeply entrenching scandalous affairs they find themselves in. One example in the making; affairs at Stanford Business School.

But my own PhD thesis is a kind of different tale altogether. For my work there is no CP Violation.
In CP Violation two leptons (electrons and positrons are leptons) are imparted quite good amount of energy and made to collide against each other. Thus just like in CERN lab, there is a much smaller tunnel at the Tsukuba facility, called an accelerator-detector facility. In this facility an electron and positron pairs are given enough energy and made to circle in opposite direction.
When they collide, they are made to do so, right inside the detector. They produce pairs of B-mesons. The B-meson one and two, they are almost at rest when they are produced, in the lab frame of reference. But the matter of fact is the B-mesons are produced from what are called Upsilon (4S) mesons.
These Upsilons are called resonances, and they are highly unstable (all resonances are short lived elementary particles). So they turn into B-mesons as soon as they are created. More…
Are younger generations opposed to Capitalism? This is a guest post by Sabuj, who writes with much clarity on Quora and I thought this is interesting enough to be shared on this website. He also writes voluminously about various issues of his interest. Since he is very young, it throws a particularly refreshing view into limelight and I would urge you to read this and comment and importantly share this if you liked this. I also invite anyone interested to make a wider audience of his/her interests in creative writing connected to academics (such as science, philosophy, history and sociology in regards to science, cutting edge research and conceptual innovations etc but this is not to say this is the end of the list) can send me a link of his/her article or email me the write up to email@example.com. I would be glad to publish it here if its devoid of any basic concerns and encourage you to suggest a good writer of science, sociology, philosophy etc to contact me, who wants to write here occasionally or regularly. This is not a paycheck generator so you may as well get an unhindered interface to the wider world. (No its not a commercial website as of this moment or any closely seen future ) Its sole aim is to bring the new and fresh to the widows of the inspired world.
Here is Sabuj’s Article. I hope you all enjoy it.
Let me answer this as someone from the “younger generation”. To begin with, your assumption is incorrect. Today’s generation is not completely against capitalism – at least not against the spirit that an individual should be able to benefit economically in exchange of and in proportion to his/her services to the world. We couldn’t even dream of the revolution in information technology and software engineering without capitalism. I am sure your friends do use the products and services which are the outcome of capitalism for the ease of their lives, even though they may be critics of capitalism itself. More…
I have been thinking of writing a basic introduction, on this important physical concept — of, what’s a Coriolis Force.
Its one of the interesting ideas of physics, which does not get as much of a mention, unless you just happen to know this, because of your advance footing, in the discourses of Physics; perhaps because its two orders of magnitude smaller, in its strength, compared to relevant forces, in a situation, that involves this small — but, significantly measurable force.
So, what’s a Coriolis Force?
I presume that most of us would be aware of, what’s centrifugal force. Its in this connection, that, a Coriolis force is most understandable.
So, what’s a centrifugal force?
A Centrifugal force, comes into picture, every time a centripetal force comes into consideration. A centrifugal force is the corresponding pseudo force, of a centripetal force. So, for every centripetal force there would be a corresponding centrifugal force.
So, we need to shed light on a few things, before we understand, what are Coriolis Force. We need to therefore discuss; what are pseudo forces and what’s a centripetal or a centrifugal force, then a coriolis force would be clearer, to the root.
So lets begin with Force.
Force has a basic standing in Physics, in connection to, in what frames of reference we need to measure such a physical quantity, as are all other physical quantities to be measured, have a significance, as to; in what frames of reference we are measuring these quantities in. More…
