Abstract Confusions

Complexity is not a cause of confusion. It is a result of it.

Favorite Comics Heroes From Childhood

I was introduced to comics by my father at a early age mainly to enhance my reading skills. My father would buy me comics on weekends or holidays. Most of the time, I would exchange comics with relatives and school friends. Thanks to the wonderful 1990s. In TV there was only Doordarshan, and we dint have cable connection either. With Doordashan dishing out more and more Hindi programs, a poor tamilian could not do much but to look else where. Comics was just perfect. It offered action, thriller and awe, all in Tamil. Tamil comics world was dominated by “Lion Comics” and “Rani Comics”.  I will list my childhood heroes.

Tex Willer

Tex Willer is my favorite comics hero. For some strange reasons I like his story line set in west. The stories are linked to native red Indians, fights and mysticism. He has no special powers. He handles rifle with at most precision and rides horse all the time. He and his son Kit, his friend Kit Carson and assistant Tiger solves major native Indians problems.

Barbarians led by Bill Gates

Recently I read a book about Microsoft’s Operating systems – Windows.

This happened to be a good read if you have interests in product / software development. I have long cherished other operating systems, like Linux and other UNIX systems. Mainly for their ability to do things and robustness. Windows was never in picture. After I finished reading it, I had a complete new look towards Windows.

It is of like, poor chap, he has tried so many things. No wonder why he couldn’t be like Apple mac or Linux OS.

Few pointers from the book.

Gravity Puzzles

Mother nature is full of surprises and physical world is no exception. Forces for example are all of same nature. In the sense, they does the same thing. Of all the various forces, gravitational force, electrical force, electro-magnetice force and nuclear force are of some interest. Gravitational force is the one discovered earliest. In 18, 19-th centuary,  people were able find the connection between electric force and magnetice force.

Gravitational Force

Late 19th centuary and early 20-th centuary developments could relate mass to the energy and other various break-throughs. It is gravity with refused to giveup. I am going to discuss about “gravitational force” here, which is supposed to be most puzzling force ever. We all know by whom, how and when gravitational force was discovered. I am not going to get into that. I was taught and thought that gravitational force the strongest force. Because of which I, you, the chair, desk and the computer I am keying in this sticks to the earth. This very thought is challenged now.

And I read a book

All this changed after I read this book written by Michio Kaku. Kaku describes gravitational force as one of the maddingly weak force.

various forces

The various forces of nature - gravitational, electrtical and weak forces.

So far, gravitational force is only force which has evaded every scientist from the grand unification. A theory which could explain every force acting on the universe is known as unified theory. Such theory, single equation is supposed to explain electric force, magnetic force, nuclear force and last but not least gravitational force.

Unified Theory

Such a theory is to be called as the “grand unified theory”. Theoretical physicists who are working on this have put enormous effort in unifying the strange force, ie, gravitational force.

Why is it that gravitational force is strange? To put it in simple terms, say, earth needs the entire weight of it to keep the pieces of paper on the desk. But where as, if I could rub a comb to a hair and show it to the paper, due to the electrons the comb gained, could attract the paper and levitates it. Overwhelming the gravitational force. But still you could see that rockets and aeroplanes waste so much energy to escape the G force.

F = \frac{G \times M_1 \times M_2}{r^2}

The force F is measured using this formula given by Issac Newton and depends on mass of the objects and the distance `r’ between them. In this case,mass of earth and that of paper.

Supersymmetry and String Theory

Going forward several theories are proposed to unite gravity with other forces. Supersymmetry is one such theory. This theory proposes that every particle has a super particle or alternative particle. It has it’s own pros and cons. Then comes string theory. String theory involved considerable amount of mathematics in it. So much so that, mathematicians have demanded that string theory should be treated as branch of mathematics in its own right. There is another theory, combining string theory and super symmetry – super strings.

It would be really great to see an unified theory which could explain all forces in one equation. Hoping that it will be accomplished in our life time.

If God was a…

Just now started reading the book – “If God was a banker” – by Ravi Subramanian. On the outset the book looks good and easy read.

Might take a week or more (Oh., I am really not sure how long I am going to take… :-D) . So, just wait for the review when I have finished reading and update you on this.

Update: I have finished reading the book on 25-Feb-2008 Monday. Expected to write the review soon. 

Penrose in Quantum Computing!?!

I never knew the fanciful applications of mathematics in physics. First, I am poor at physics and not interested in it. But when I read this entry, I was amazed.

I have already posted an entry about the book I read in my googlepage. The book in Emperor’s mind written by Roger Penrose. He invented a new way tiling and the method is known as Penrose Tiling.

Go ahead and read it! It has very good basic details.
