Description

A theory called special relativity describes the characteristics of stuff moving at speeds close to the speed of light. Albert Einstein created it, and it was released in 1905. Ordinary Newtonian physics is fairly accurate in describing motion at speeds that are low compared to the speed of light, but it fails at very high speeds. For all speeds, special relatively is valid. The most beautiful physical theory ever created is relativity. It provides clear predictions that have been spectacularly confirmed by experiment and describes one of the most prevalent aspects of the universe we experience: gravity, in terms of an elegant mathematical structure known as the differential geometry of curved spacetime. Einstein proposed two postulates in the first section of his 1905 paper, which serve as the foundation for his special theory of relativity. The relativity principle comes first. The only thing that such an experiment can really show is motion relative to another frame; nonetheless, it cannot support the claim that one is truly at rest while the other is in motion. Postgraduates, undergraduates, secondary students, physics researchers, professionals, and anybody else interested in science should find this book important.
