Relativity : Speed of light

Speed of light is the key point theory of relativity hinged upon. It has marvelled the scientists before its actual values was known and much dwelled upon later. Earlier it was thought to be infinitely large but later discovered of having a finite value. The book covers all the fascinations and strange properties associated with it and an eagle eye view of theory of relativity as well as.Newtons laws has contradiction with Electrodynamics and thermodynamics. In Electrodynamics Relativity resolves this contradiction by postulating that speed of light is constant. This gives Lorenzs local time a physical sense in the way sand-watch of pre-newtonian physics produces the meaning or definition of time as: equal causes takes equal time to produce equal effects. Now you have a clock where a photon is bouncing between two parallel mirrors. The rest of relativity follows accordingly.To formulate Newtons laws newton uses calculus.The book goes into the some details of calculus to understand the basic defects of Newtonian physics which is the formulation of d/dt in Newtons second law.
