Information, simple but requires some study
By Shounak Bhattacharya,
For readers who are thinking that it is a very simple book, casual read, sitting on sofa or while traveling, surely this is NOT THE BOOK for you. This is a book which is written by one of the greatest scientist of our generation who has been given the honour with Einstein.
Why the book is popular? Dr.Hawking's motto was to reach to buyers in airport, specifically to the mass, which definitely would have made it half if there would have been equations and that is the reason, why the book is so difficult.
What is there in the book?
A basic idea of the history and development of cosmology starting from Ptolemy's Universe, Copernicus, Galileo to the current understanding.
Space & Time: (a) Galilean relativity and measurement (b) Newton's laws of motion (c) Emerging ideas of gravity (d) James Clerk Maxwell's emergence of the famous theory of electromagnetism -- The first step towards unification, unifying 2 separate forces, electric and magnet into one.
The Expanding Universe: (a) Hubble's observation (b) Doppler effect (c) The red shift (c) Friedmann model. Here. Prof.Hawking starts introducing the concept of singularity: the extreme prediction of General relativity.
Most importantly the electro-weak unification by Weinberg-Salam theory. So, we now have only 3 major forces of nature as per the Standard Model: (1)Electro-weak (a sum of electromagnetism and weak force) (2) Gravity (3) Strong force. For a better understanding please look into: Dr.Mani Bhaumik's Code Name God.
Dr.Hawking ends the book with an optimists note: 'A complete, consistent, unified theory is only the first step; our goal is a complete understanding of the events around us, and of our own existence.'
'If we find the answer to that, it would be the ultimate triumph of human reason - for then we would know the mind of God.'
Happy reading !!
Worth evry penny...

One of the best books on scientific topics, he ease with which S.Hawkins has described so complicated n complex matters is really overwhelming. If you really want to gain knowledge but hesitate to read science journal for complex maths equation then this is the book for you. So simple and no equation yet very informative.
Special thanks to Infibeam for delivering the book so fast, but I must confess that this time the packing wasn't upto the mark, even though the book was undamged yet it was very close to being dameged.Please take care of packages as we consumers trust this website a lot.
