The logic of God and Evil

Although I always wanted to make a flowchart like this, I was too busy (lazy) to do so.

But somebody made it, by God's grace. I stumbled upon it over the web.

The Chaos Theory - A layman introduction

I spent my Sunday learning about Chaos, Fractal and Self Organisation.

A beautiful and charming concept. I have been trying to get my grip over it for since I first came across it(~2011), but I was always left in bits and piece. A recent book I read made the magic.

The reason why this is beautiful is because of its elegance and importance in understanding the very basic working of nature.

PS- There is a movie based on Chaos Theory. :)

Before you go-to IMDB, you gotta know what Chaos theory actually is.

Chaos- In layman term.

Let say you are practicing basketball. But instead of ball, you have marbles. Now you throw the marble for the first time. You miss the basket by huge distance. Now you realize you have to throw it a bit left. You do this. Again you fail, but this time the distance is reduced. You shift you trajectory a bit more and again you fail but with a lesser distance.

After number of try, you realize the actual trajectory and the elbow angle needed for throwing the marble right in the center of the basket. Yupi!!!

The twist is here. Now even if you throw the marble a little bit left or right, you have a chance of not missing the basket. What this means is, a little bit of change in the initial condition does not change the result of the system to tremendous amount.

This is what we call as Newtonian Systems or Deterministic system. These are system which have initial conditions (the elbow orientation, the trajectory, the size of marble), set of fixed rules/laws (the law of motions, the law of gravity governing the marble, the air friction, etc) and the output (in this case the marble landing in the basket).

Simply, INPUT + LAWS -----determines-----> OUTPUT.

In a Newtonian system, if we know the initial condition and the laws, we can predict the outcome (as in case of marble-basket game, you can predict that if you keep the initial condition and set of rules same, the marble will land in the basket).

But there are some system in nature which is not predictable. What we mean by this is, even if you keep the keep the laws/rules the same and just change the input a little bit, the outcome can be drastically different from the predicted.

Simply, INPUT + LAWS ------doesn't determines -----> OUTPUT

This is a what we called chaos. What it means is "even if you know the exact input and the set of rules governing the system, you can never ever predict the outcome of that system."

Example-

The first mention of chaos theory was by MIT meteorologist Edward Lorenz. Lorenz was working on a new software which was built to predict the weather for future based on same input data (temperature, pressure, humidity,wind velocity, etc). This was based on mathematical equations.

When Lorenz gave some input to the system, he got a graph like this.

|

|

|........---__----.....-----....-------.......------

|

|_________________________________________

Lorenz just re-ran the whole program again with the same input and same software. Surprisingly, this time the input was astonishing different.

|

|         /\             / \

|......../ \..., ,......./ \......., ,......./\.../\......

|              \/                   \/

|_________________________________________

Lorenz was amazed. He checked the input and the calculation once again thinking it was his mistake. Astonishingly, every thing was similar to the last run. Why has the system produced such a different output.

Lorenz realized that there is some changes in the initial input values.

In the first run, the values were like 0.98453 or 12.32470 or 3.6614.

In the second run, the values were 0.984 or 12.324 or 3.661. i.e., the values were rounded off to 3 decimal places.

Lorenz realized that the determinism fails even if you change the value by just 0.0001. That means if there is just a minor change in the input field, the software will show rain instead of winter at particular place. He realized that this is a big failure and that not all system in the nature is deterministic. What this means,there are some system to which you can never determine the output to utmost accuracy, no matter how hard you try, this is because the initial data of some system can never be known with complete accuracy (like weather).

The consequence of this theory is something called as Butterfly Effect. 

It says that flapping of a butterfly's wings in South America could affect the weather in Texas

This is CHAOS THEORY in a nutshell. Happy learning!

The Conversion Factor

Going around Mumbai roads, you will quite frequently  come across this hoarding these days.

Pay attention, keep your mobile phone aside. Think about the following.

• This poster or advertisement has no “responsibility tag”. What I mean by this, the poster has no names of the organization of the committee who are responsible for this.
• This poster has no “description” of what it is all about. All it speaks about is change or parivartan (in hindi).
• It has Johnny Lever and Nagma. Both of them a known television stars. Good selling point.
• It offers you free books and free sessions. Just call on the number. Maybe just a miscall will do

It is always now....

"It is always now 

i actually want to talk 

today about death 

now most of us do our best to not to think about death 

but there's always part of our minds that knows 

this cant go on forever 

part of us always knows 

they were just a doctor's visit away or a phone call away from being starkly 

reminded 

with the fact of our own mortality 

or of those closest to us.

Now i'm sure many of you in this room have experienced this in some form 

you must know how uncanny it is 

to suddenly 

be thrown out of the normal course of your life 

and just be given the full time job of not dying 

or caring for someone who is.

But the one thing people tend to realize 

at moments like this is that they wasted a lot of time 

when life was normal 

and it's not just what they, it's not just what they did with their time, it's not just 

that they 

spent too much time working or or compulsively checking email 

it's that they cared about the wrong things 

they regret what they cared about 

their attention was bound up in petty concerns 

year after year 

when life was normal 

and this is a paradox of course because 

we all know 

this epiphany is coming 

i mean, don't you know this is coming? 

don't you know there's going to come a day 

when you'll be sick or someone close to you will die 

and you'll look back 

at the kinds of things that captured your attention 

and you'll think, "what, what was I doing?" 

you know this, and yet if you're like most people, 

you'll spend most of your time in life 

tacitly presuming you'll live forever 

it's like watching a bad movie for the fourth time 

or bickering with your spouse 

I mean this, these things only makes sense 

in light of eternity 

there better be a heaven if we're gonna waste our time like that 

there are ways to 

really live in the present moment 

what what's the alternative? 

it is always now 

however much you feel you may need to plan for the future 

to anticipate it, to mitigate the risks, 

the reality of your life is now 

this may sound trite 

but it's the truth 

it's not quite true as a matter of physics, in fact there is no now 

that encompasses the entire universe you can't talk about an event 

being simultaneously 

occurring here and one 

at the same moment occurring in Andromeda 

the truth is, now is not even well-defined as a matter of neurology because 

we know that inputs to the brain 

 come at different moments and that consciousness is built upon layers 

of inputs whose timing to have to be different 

are conscious awareness of the present moment is 

in some relevant sense already a memory 

but as a matter of conscious experience 

the reality of your life 

is always now 

and i think this is a liberating truth about the nature of the human mind in 

fact i think there's probably nothing more important to understand 

about your mind than that 

if you want to be happy 

the past is a memory 

it's a thought 

arising in the present 

the future is merely anticipated, it is another thought 

arising now 

what we truly have 

is this moment 

and this 

and we spend most of our lives forgetting this truth 

repudiating it, fleeing it, overlooking it, 

and the horror 

is that we succeed 

we we've managed to 

never really connect with the present moment and find fulfillment there because we 

are we are 

continually hoping to become happy in the future 

and the future never arrives 

even when we think we're in the present moment we're, we're in very 

subtle ways, always looking over its shoulder 

anticipating what's coming next 

we're always solving a problem 

and it's possible to simply drop your problem 

if only for a moment 

and enjoy whatever is true of your life in the present 

this is not a matter of new information 

or more information, it requires a change in attitude 

it requires a change in the attentiveness you pay 

to your experience in the present moment "

Why Do We Fall In Love?

The following is what I wrote for a QA website. It is a bit poetic, yet it has the smell of science and evolutionary biology in it! I have oversimplified it, but the intend to give a rough idea behind of science of love is fulfilled.

Why Do We Fall in Love?

Okay. Simply to mate. 
Fine, To mate better.

But wait, can't we mate without loving?
Yes we can. Most of the other animals do it that way. Look around you.

So why love?

The more evolved (in term of Natural Selections) an organism is, the more complex the process of mating becomes. Compare algae and consider a dog. Huge difference.

"I won't mate with just anybody ". said the brain at some point of evolution. I will search for the best. Wow. This became the golden rule for sex and thus for evolution (you be dumb to say sex is not tightly coupled to evolution.).

Best? What do you mean by best? The strongest, the fastest, the tallest, the coolest, the healthiest, the nerdest. The 'anything-est' I mean.

And one more thing, the most Trust worthy. Females don't want to take care of the baby alone (obviously , why would they you sick sexist!).  Human mind has then developed a system to separate the perv and the fuckers from the genuine and caring mate.

This system is called LOVE.

Consider world without love. How do you check whether somebody cares about you truly or is just hanging out with you to fulfill his/her (I support gay marriage!) sexual desire.

Love is like a meter for us to measure the likelihood of somebody been a good, caring, long lasting, sexy, yummy, delicious mate!!!

The purpose is same, the process is same, the style of execution varies..

Immortality- What I learn from Matt Ridley

"Nothing last forever, and we both know hearts can change, 

It's hard to hold a candle, in the cold November rain...."

--November Rain - Guns N' Roses.

How perfectly poetic can life be. Nothing last forever, you may have heard this phrase many a time in your life. This is just a spread-out version of saying, things are mortal.

With all my senses, I somehow say this, Science is beautiful, as Carl Sagan says, a candle in dark. It can answer quite a lot of question. It maybe wrong in many places, but it is a self correcting enterprise. It is open to questions, and changes.

Genes are immortal. They have, metaphorically speaking, traversed the planet from the dawn of life, till the present moment. Four billion year of journey, fifty million times photocopy, and yet they are, intact in the most purest sense. 

Consider this, take a original copy of any document, take it to the photocopy machine(most people call it Xerox. This happens when a brand name becomes a parasite. It is called genericide). Start making a copy. From original make the first copy. Call it copy1. Now from copy1 make copy2 and so on. By the time you reach 120-130 copy, you will start feeling that the original is nowhere exactly similar to the copy120. If you do it more, after certain number of copies, the page would be loosing its originality. But look at your genes. 50 million times photocopy, and yet as perfect as they are. Amazing I find this to be.
