Shaman and the light

In Uncategorized on March 28, 2016 at 11:25 pm

Once upon a time… There was a little paradise, on the edge of the earth. Surrounded by blue waters and green forest, full of tall trees, crystal clear streams, flowering vines and beautiful ferns. With beautiful birds, butterflies, animals and insects. And people there were innocent and happy.

One day, a beautiful being came to a lonely man wandering in the forest. The being told the man that they all are in ‘darkness‘ and that is pathetic and he can offer a way in to something called ‘light‘. He said it is the most beautiful thing in the world. The man, hypnotised by the being’s charisma wanted to see that amazing thing he was mentioning. And the being said, it need some work. You have to do that nobody in the world has done before. You need to ‘think’. And the man didn’t know how to think and the beautiful spirit taught him exactly that.

The man started practising ‘thinking’ and started telling all the people that he knows to ‘think’ and what the spirit told him. People wanted to try too, but most of them could’t do. So they told the man, why don’t you do it and let us know what that ‘light‘ is like. The man agreed and kept thinking and thinking and thinking…

Days and nights gone by, weather kept changing, and he can see everything getting black, shady and empty. People and animal and all living things are fading and becoming shadows. He didn’t stop, he continued thinking in order to see the beautiful ‘light‘. He thought the being was right. We are in ‘darkness‘.

One such dark day, he felt everything was darker than ever and ‘light’ appeared in front of him. He looked at it in excitement and only to find that it is the ugliest thing he has ever seen in his entire life. While he stood there frightened, the ‘light‘ stared at his eyes and said to him that, ‘I was looking for you for so long, I can’t leave you now, I am going to be with you for ever’.

The man can’t believe himself. He looked around the darkness sat down exhausted. The light followed him..

The next day, others saw him in the woods, blind and deaf, shouting ‘Don’t think, don’t think‘.

Is DNA a Turing machine?

In Uncategorized on February 8, 2015 at 12:57 pm

Answer by Anand Mallaya:

DNA may not be a Turing machine, but it can,very much likely, be part of a Turing Machine.

A Turing machine consists of
1. A Tape – A tape divided in to cells. Each cell capable of holding a symbol from a finite set of alphabets.
2. A Head – Which can move left or right through the tape and read the alphabets in the tape.
3. A State Register – A register which stores the state of the machine.
4. An Instruction Table – Which based on the state of the machine and the alphabet on the cell in which the head is currently reading, performs one of the set of predetermined actions.
Examples of instructions can be like
        Write an alphabet on the cell
        move the head right or left
         stay on the same cell etc.

If you compare this with a biological cell, we can find many interesting features of the cell which can be related to a turing machine.
         Tape <=> DNA
         Head <=> Ribosome
         State Register <=> RNA
         States <=> Amino acid
         Instruction Table <=> DNA codon table
         Ouput Tape <=> Proteins

Formal Definition of Turing Machine

A (one-tape) Turing machine can be formally defined as a 7-tuple

where

  • is a finite, non-empty set of states

  • is a finite, non-empty set of tape alphabet symbols

  • is the blank symbol (the only symbol allowed to occur on the tape infinitely often at any step during the computation)

  • is the set of input symbols

  • is a partial function called the transition function, where L is left shift, R is right shift. (A relatively uncommon variant allows "no shift", say N, as a third element of the latter set.)

  • is the initial state

  • is the set of final or accepting states.

The Function
The function being performed is finite time and is the  Protein biosynthesis

 

The Instruction Set

Notable differences are

  1. The head only moves in one direction.
  2. The output tape is different from the input tape

Is there an evolutionary reason as to why the fingerprints are unique?

In Uncategorized on January 23, 2015 at 11:30 pm

Answer by A Quora admin:

Good question. As far as I know, there are no explanations yet.

My wild guess is that it could be a mathematical characteristic than an evolved trait. Morphology and Morphogenesis, the branch of biology which study about the form and structure of organisms are getting more associated with mathematics , so is Developmental biology.
Recent studies[1][2] confirm old theory proposed by mathematician Alan Turing on how patterns arise from simple reactions [3]. The patterns formed like stripes of zebra and tigers were able to explain by this model. Since finger prints are similar in nature, I strongly believe that it may be emerging from similar reactions which may not need to have to be beneficial if not harmful. The cellular division and the formation of skin may have similar dynamics which leads to the signature patterns. Since the DNA is unique, it may be affecting the reaction parameters indirectly.

How does science explain God?

In Uncategorized on January 23, 2015 at 10:40 pm

Answer by A Quora admin:

Though the scientific world has not yet came across this, but what I understood, could be the basis of the current form of definition of God.

For understanding the idea, one need to learn few concepts which are mentioned below.

1. Humans are animals and Evolved from other animals now extinct.

2. The advantages of social evolution helped forming complex systems of individuals through mutually beneficial act than selfish acts. Though the underlying dynamics may be still selfish in nature.

3. Many social animals have evolved to follow power based hierarchies. Alpha males were genetically superior so that the system evolved to benefit by co-operating with other members of the social group to harness the power of unity. For e.g. hunting in groups may be efficient than hunting alone. Even though the alphas may be superior than the common member, the dynamics favoured co-operation because of the efficiency

4. In human societies these alphas were the tribal chiefs, the religious leaders, the shamans, the kings etc. Such individuals had huge influence on the rest of the members in their survival. Such alphas were got selected naturally that the society as whole benefit more. In return, the alphas enjoyed better quality of life and rights.

5. Since the qualities that enabled the alphas (intellect, physical capabilities, health etc.) were mostly genetic, artificial selection were possible and to preserve their superior capabilities, specially selected royal families were formed eventually so that best of the genes are accumulated in the family.

6. With rapid change happening in the human society, for preserving their power, the royal families and their close groups have identified that the power is becoming more and more about the faith of the rest on the superiority of the royal ones than how relevant the qualities that run in the family today. So they invented idols and symbols. Because individuals are subjected to death and other weaknesses, idols were used to preserve their memories and keep the people in the loop. The power now transformed to the symbols and anybody close to the symbols kept possession of the power, be it the priest or the king. Pharaoh , Imperial cult

7. Eventually as the kingdoms paved way to democracies, we are left with the symbols and stories that once were tools used by the royals to maintain their power. Now with the societies evolved to get rid of the costs of maintaining the alphas, many are still maintaining the ages old traditions and believe systems which ones were essential to the survival for the society as a whole, without having much clue or need to learn about the truth.

TL;DR
Kings invented Gods.

So The GPS is a weapon?!
Government must be knowing about this critical vulnerability. And if they allowed it, is it meant to be like that? A weapon?

Why did DNA evolved in to chromosome?

In Uncategorized on June 16, 2013 at 10:41 pm

What is the reason for the DNA to be organised as chromosomes? In earliest(in evolutionary terms) and simplest organisms, DNA is is found as one unit. But higher in evolutionary ladder, the DNA gets organized in to multiple units(i.e. chromosomes). So what is the reason behind this.
Is it 
– due to the physical properties of long chain molecules?
– organised according to the functions of the part of DNA (modules?)? (for e.g. each chromosome is associated with a particular organ system( reproductive, audio visual, respiratory, digestive..)
– just random?
Is there a direct correlation between number of chromosomes and evolutionary advancement(chronological)?

What is time?

In Uncategorized on February 26, 2013 at 11:46 pm

Answer by Anand Mallaya:

When ever I collide with this question, every answer I get is like when asked about "what is a boat?", getting an answer : "a boat is a small ship".

EDIT For e.g. Take the term change which is often found in most definitions. The term change itself doesn't have proper meaning with out a reference to the concept of time itself.
Being said that, according to special and general relativity , space and time are one single entity.

EDIT:(Got a new insight, comments are appreciated) Assuming The Big Bang theory is a reality, and what was happening since big bang is the expansion of the universe from a singular state where all the matter was confined to the smallest unit of space. This give raise to an increase in total entropy.Absolute Time is the distance between each steps(quantum of space) at which the matter expanded.
OR
If the initial singularity changed its state, say to photons, and if it can only take defined states in space(assumption), then a step of time is the number of quantum distance the original photon covered since the big bang.

Wonder what numbers has to do in a tech blog? I will tell you.
In a series of posts we will explore a group of numbers that are fascinating and mysterious. Let us start with prime numbers.

Prime Numbers

A prime number is a number which has only two factors, 1 and the number itself. In other words it is divisible only by 1 and itself.
2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53, 59, 61, 67, 71, 73, 79, 83, 89, 97….
Prime numbers are enigma not only for the school children but the top mathematicians and even the best computing machines of our time. I was fascinated by the beauty of the numbers many times. They are the building blocks or atoms of all other numbers. Any other number can be represented as a product of two or more prime…
