Part I The Edge of Knowledge Chapter 1 trussed Up with Strings This is the introductory section, where the author, Brian younge, examines the fundamentals of what is currently proven to be true by experimentation in the realm of modern physics. Green goes on to talk more approximately "The Basic Idea" of drawstring opening. He describes how physicists are aspiring to reach the Theory of Everything, or T.O.E. somewhat suspect when string theory is completely understood that it might unloose out to become the T.O.E.Part II The Dilemma of Space, Time, and Quanta Chapter 2 Space, Time, and the Eye of the perceiver In the chapter, Greene describes how Albert nous solved the paradox about lax. In the mid-1800s crowd Maxwell succeeded in showing that light was really an electromagnetic wave. From this he concluded that light always travels at the speed of light. It never slows down. brainpower asked the question "What happens if we chase after a beam of light, at li ght speed?" From reasoning based on Newtons laws of motion, one can suck up that the light would appear stationary. But according to Maxwells theory, light cannot be stationary. Einstein solved this problem through his special theory of relativity. Greene continues with his explanations of the special theory of relativity.Chapter 3 Of Warps and Ripples Green begins the chapter by describing "Newtons View of Gravity" and continues by discussing the inconsistency of Newtonian Gravity and Special Relativity. The author also talks about how Einstein discovered the link between acceleration and the warping of situation and time. Greene also discuses the basic aspects of General Relativity. He later points out how the dickens theories of relativity effect black holes, the big bang, and the expansion of space.Chapter 4 microscopicalal Weirdness This chapter describes, in detail, the workings of quantum mechanics. The author tells of how waves are effected by quantum mechani c. He also discusses the fact that electromagnetic radiation, or photons, are actually particles and waves. He continues to discuss how matter particles are also matter, but because of their h bar, is so small, the effects are not seen. Green concludes the quantum mechanics parole by talking about the uncertainty principle.Chapter 5 The need for a New Theory General Relativity vs. Quantum Mechanics This chapter compares the theory of oecumenic relativity and quantum mechanics. It shows that relativity mainly concerns that microscopic world, while quantum mechanics deals with the microscopic world.
