priest of the universe

Stephen Hawking was one of the legendary figures in the world, the man of deep thinking and high dimensional imagination. Stephen Hawking was an English born theoretical physicist, working in the field of cosmology and the evolution of the universe. 
Hawking was an ordinary student with long term passion for natural science and mathematics because he believes that mathematics is the only accurate tool to  define and think about the complex universal system. but her one of the tragic moments happened during the time at oxford. He becomes paralyzed and more fragile to move. Doctors gave a time limit for her life, he never exists for more than one or two years, but he rose from the limit, he found her soul mate jane Wilde as her partner because she gives the courage and motivation of importance of life. he lost his voice and body after a series of treatment.but he never fails, he published her research paper the expanding universe, finally, he got the doctoral degree.


Then he decides to write a book about the time , the holy grail in the science, a brief history of time is a remarkable book with extraordinary publication records and record translational rate.
             Book Cover Concept Of Stephen Hawking S A Brief History - Book ... 
 The book consists of not more than 200 pages with a lovely explanation of the complicated cosmological concept and theories, mainly focused on the common man without any extraordinary knowledge in cosmology, for researchers it is a brief outline of the universe . The book starts with an introduction by Carl sagan .it consists of 10 chapters with a brief description of the topic.
                            
The first chapter begins with the historical development of universal studies that began with Aristotle and ended up with Newtonian mechanics and his wonderful theory of universal law of gravitation. The chapter mainly focused on the contribution of Ptolemy, Copernicus, Kepler, Galileo, and Newton.normally  the chapter,'the our picture of the universe 'discuss brief outline the transformation of natural science to the Newtonian era of astronomy.

The chapter began with some fundamental questions of the existing universe and also the evaluation and finding of Aristotle, based on the book the heavens .and the concept of stationary earth and moving celestial objects.
The second concept about Ptolemy s geocentric theory and its properties. It was a wonder-full concept that rules the intellectual community more than centuries.
Then the next era began with the development of the Copernican s heliocentric model. Galileo supported the concept finally ended up the era after the inqusistion.but the problems were solved by the Christmas star, Issac newton. The book explains Newtonian mechanics and its impact on the celestial object. The braking outcomes of the book Naturalis Principia Mathematica.

The last part of the chapter deal with the philosophical aspect of the theories he argued and explained based on Karl popper concept and another leading school of philosophy includes the metaphysical analysis etc, but it was more interesting and eye-opening thoughts of topics.
The second chapter is named TIME AND SPACE. the fundamental entity in theoretical physics. This section includes the comparison of observations and calculation from the Aristotelian tradition to the modern einstein maxwell combination. It discusses the Aristotelian concept of weight than its existence , but galileo demonstrated that Aristotle s belief was false by dropping weight from the leaning tower of Pisa. Then the theory modified by the newtons3+1 concept, three law of motion and the law of universal gravitation. But the common feature of Aristotle from newton is they believed in absolute time, which means time completely separate from and independent of space.

        But the concept of absolute time was wrong and the new turning points began with the danish astronomer ole Christensen Roemer. He calculated the speed of light by observing Jupiter's apparent movement and other properties.But the new rea was started by British physicist James clerk maxwell and her electromagnetic theories, this section includes the concept of electromagnetic property and speed of light. Include the existence of ether medium and Michelson Morley experiment claim that there is no such medium as ether. The chapter ended with the concept of relativity from a classical explanation to the modern einstein version. Include the einstein mass-energy equivalence equation, the correctness of aberration of mercury, time and space curve, the nature of the universe , the concept of gravity is nor a force but a phenomenon of the capacity to bend space-time curve.
The third chapter is named EXPANDING UNIVERSE,  mainly focused on the result of Edwin Hubble's law of expanding universe, its outcome results, and the development of the concept by various other scientists.

The other two chapters the uncertainty principle elementary particles and the forces of nature is the simple pellucid explanations of particle physics-based analysis. uncertainty theory of Heisen Berg was an important theory in both quantum mechanics and cosmology, this chapter deal with beautiful concepts of particle physics, you can understand it easily. Elementary particle and the force of nature deal with the grand unified theory of force, combined version of four fundamental theories of nature. Wich help to explain the state of singularity and the early version of the universe, but it was difficult because of the fundamental forces,electromagnetic force,weak and strong nuclear force are existing in micro-level of observation but the remaining force gravitation was a macro force, so the combination possible only through the advanced concept like string theory, super dimensional theories, and particle accelerator analysis. The remaining section includes matter and matter, particle accelerator and its future. .standerd models and the fundamental particles, properties, etc.
      The other chapters discuss what is time and space, black hole and the developing universe. He argued that time is not a constant through the universe, he introduces one of the magical realities of time like, time travel twin paradox, etc.
Then he discussed universe and its property, he explains Hubble's observation of expanding universe.
  After the big bang theory, he explained the wonderful result and observations about black holes. He explained what is a black hole , where they found?how do we detect? is it harmful to humanity?
     
                
The book is an amazing keyhole to learn about the universe simply.You can find the reality of the complexity of the universe.Get the book know to read it find the beauty and the reality
