My analysis of Odisha elections-2017 Reply

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.

Inherent ability = difficulty * accomplishment. Reply

All of Physics is this “Inherent ability = difficulty * accomplishment”. Thats just intuitive but can easily be seen to correspond mathematically with the Principle of least action.

First the edifice: whats the problem? The problem is given you move in straight line when every direction is same around you, which direction will you chose? While you are waiting for a good answer from astrologers intelligent people already give a good hint. Think you have some inherent ability which is fixed.

fixed: which changes only if estimated wrong.

That inherent ability is actually action. Accomplishments are adjusted for difficulties, you waded through a swamp 5 meters you would have accomplished in sand 8 meters with that given inherent ability called action. Because action is abstract we have been sticking to time and path-length, but they are not as fundamental, they are merely specifics. More…

Aberrations; a lecture in Optics. 1

Optical systems are studied under two assumptions

object point does not lie far away from the axis of the optical system.

rays taking part in image formation make a small angle with the axis of the optical system.

The domain of optics where above two assumptions are valid is called as Paraxial optics. Paraxial systems are highly idealized and in reality do not perfectly represent the situation. The consequential errors in image reconstruction are known as aberrations.
The paraxial assumption can be represented by truncating at the first term of the polynomial expansion of the sin function by the Maclaurin series. More…

A c++ code for calculating pi value. Reply

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.

OUTPUT
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.

The problem of eating beef. Reply

Is eating beef an act which is so morally repugnant that it can take lives? We wouldn’t imagine such with an ideally and intellectually sensitive human society. But we don’t, we live in communities which does not care so much about what it can infer as “other’s” ways. Lets not get ourselves embroiled, to believe that, thats a superfluous statement.

One would argue, we do care about others values and culture and others ways of looking at things and at a grosser level others comfort in riding a public transport, others availability and unavailability in attending to us for what we need them for.

But, I am talking about “others” as a mark of identification and not an immediately concocted response, to deal with a social situation.

At a deeper level, we often transgress, into interfering with others ways, simply because, we identify them as ‘others’. We deliberately create a ruckus, about ‘issues’, simply because, the issues do not affect us the way we perceive it affects others.

Its dishonesty and its violence. Read a short article here why I think “dishonesty is violence”.

We gang up on others and create false notions of vulnerability and mark others as adverse, simply because we have deep prejudices of defining our roles and identifications, as being markedly different, from what we confer onto those, that would not fit into such roles.

One of the determinant, in delving into making a demarcation of what constitutes ‘others’, is the idea of proving superiority. And its an age old problem, but more than that it prevails in today’s communities, in a way it would not let us make progress as humans. More…
