Title:Bhautik Vigyan ko Bikaskarm (Evolution of Physics)
Publisher:Pragati Pustak Sadan
Size:133 x 215 mm
The Evolution of Physics is a simple book written by Albert Einstein to introduce old and new theories of physics, from the classical physics created by Isaac Newton and Galileo Galilei to the relativistic and probabilistic physics he and Neils Bohr invented. This book provides a very clear description of the discovery of gravitational laws and why they were useful. It proceeds to explain weaknesses in these laws and why alternative theories were necessary. We learn that light has mass, and that metal rods traveling close to the speed of light grow smaller in size. We also learn that time is relative, and that clocks moving near the speed of light slow down. These descriptions of our physical world defy the imagination, but Einstein provides thoughtful visual stories to explain why they must be true. He supports these with observational and experimental evidence.
