The Winners Have Been Announced!

The month of October had been the month of the Free Book Contest for us. Now that the contest is over, the names of the winners have been announced. The list of people, who participated is very long and as in any contest not everybody won. But, more than winning, the idea was to connect more and to communicate better, which we all did. That way, everyone has been a winner. Those who did not win this time, there is always the next time.

The winners are from all over the globe. A few of the countries include the USA, the UK, Germany, Australia, Canada, India, Israel…A few of the names include Carolyn, Kathy, Kathleen, Terry, Chris, Walter, Margaret, Amy, Arkadeep…

The winners have already been notified by email, or will be shortly.

Thank you readers for the wonderful response and for making the contest a grand success!

Praise for The Blue Buccaneer


“I thoroughly enjoyed this book and recommend it to mystery fans.
The clear and unpretentious writing style of the author makes for easy reading as well as enhancing the fast-moving plot
The main character, Manoj, is the intelligent “detective”, who with his patience and astute observations is capable of finding out exactly who stole the famous blue diamond, called the Blue Buccaneer. I found him to be a sort of Hercule Poirot for his precise and intuitive method of investigating.
The author added a bit of wit to this character’s dialogues and this presented him with a more personal touch.
The information regarding the precious Indian treasures that are housed in the museum was an added advantage for the reader to learn about India’s vast artistic and archaeological history.”
Elaine Bertolotti author of Florence and Me
“I was intrigued right from the start…

Call of the Lost Ages: A Study of the Indus Valley Script

The inscriptions found on the various artifacts from the Indus Valley Civilization hold in their hearts hidden chronicles of time. Many unsolved mysteries remain regarding who were these people, how did they suddenly build such an advanced civilization, how were theirs lives like, how much did they interact with their neighbouring cultures, and where did they suddenly vanish . One of the most ancient and advanced civilizations, it mysteriously seems to have disappeared almost suddenly, and that too without any trace. Will the study of the script used by this civilization reveal any clue to these puzzles? Will it help us unravel these ancient mysteries? Finally and most importantly, will a study of the Indus Valley script help us in gaining more knowledge about the ancient world?

The World with Zero Postulation: Unraveling the Mysteries of Nature…

The_World_with_Zero__Cover_facebookFrom the book…

‘…The law of universal gravitation states that any two bodies in the universe attract each other with a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between them. This was the genius of Newton in seeing the same underlying force that causes all bodies in the universe, big or small, to attract each other. Using his new theory, he was able to predict with considerable accuracy the motion of planets, as well as the tiniest objects known to man in those days.

He himself was not fully comfortable, however, with the force of gravity. In a letter, he wrote ‘That one body may act upon another at a distance through a vacuum without the mediation of anything else, by and through which their action and force may be conveyed from one another, is to me so great an absurdity that, I believe, no man who has in philosophic matters a competent faculty of thinking could ever fall into it.’ He was never able to assign a cause behind the existence of gravity. In the second edition of the Principia he wrote ‘I have not yet been able to discover the cause of these properties of gravity from phenomena and I feign no hypotheses… It is enough that gravity does really exist and acts according to the laws I have explained, and that it abundantly serves to account for all the motions of celestial bodies.’

It is however to be noted that the idea of gravity was not an entirely new concept outside Europe. In Siddhantha Siromani (Supreme Results) gravity was described by the 11th century Indian Mathematician Bhaskaracharya in the following terms:

Aakrishti sakthischa mahee thayaa yathkhastham guru swa abhimukham swa sakthyaa . aakrushyathe thath pathathi iti bhaathi same samanthaath kwa pathathi ayam khe

It says that the earth attracts the objects in the sky by its own force towards itself. He discusses the forces between the celestial bodies using a question: Where can the celestial bodies fall since they attract each other?

It was much after the death of Isaac Newton that modern science began to learn about electricity and magnetism in details. Around the beginning of the nineteenth century a vague relationship between electricity and magnetism began to be understood, especially due to the experiments conducted by Hans Christian Ørsted, André-Marie Ampère, Jean-Baptiste Biot, Johann Carl Friedrich Gauss, Félix Savart, Michael Faraday, etc. However, the knowledge that was being gathered was vastly chaotic. James Clerk Maxwell (1831–1879) organized the knowledge by formulating a few general principles combining, both electricity and magnetism. His work was about finding the underlying principles that causes the various electrical and magnetic phenomena. Maxwell helped develop the Maxwell–Boltzmann distribution, which is a statistical means of describing aspects of the kinetic theory of gases…’


SnowflakesWilsonBentleyEmergence is the way complex systems and patterns arise out of a multiplicity of relatively simple interactions. This is central to the study of complex as well as chaotic systems. The simple components of the environment may form more complex emergent properties, as a whole. Relating to the closest we can get, the human perception of the world, we can say that what we perceive about the world is way greater than the signals that are fed to our bodies through our senses. When you look at a distant star, your perception of the star is way greater than the light that reaches your eyes from it.

The above image: Snowflakes (by Wilson Bentley) forming complex symmetrical patterns is an example of emergence in a physical system.

Building a Foolproof Navigation System: Fuzzy Logic Emulating the Brain

Screenshot from 2014-07-29 04:26:23Our aim is to help build a machine that can reduce the possibility of mishaps in navigation to zero. For that devise a new system of numbers, in which the real numbers are represented on the y-axis and complex numbers on the x-axis. Inside such a system, we incorporate the equivalent Ideal Fuzzy Logic that can be used by the machine to predict and avoid mishaps.

Natural processes are vastly emergent phenomena and each new result is always the source of new emergence. To cope with nonlinear control problems, binary logic is no longer sufficient. What we need is an ideal Fuzzy Logic that not only can process complex numbers with utmost efficiency, but also ‘thinks’ in terms of complex numbers. Such a system also needs to be as simple as possible for us and for machines to work with.

A perfectly efficient navigation system will be able to receive inputs that have all sets of possible values. These values may be real or imaginary. Such a system will be particularly efficient in dealing with imaginary numbers and will be able to reduce the probability of a mishap to zero. Read More Here…
