What is relativity all about? ￭ Newton's laws of motion give us a complete description of the behavior moving objects at low speeds. ￭ Einstein's Special Theory of Relativity describes the motion of particles moving at close to the speed of light. Special means that the theory deals only with inertial reference frames。 Space and time are entangled（牵连）. 相对论是关于物质运动与时间空间关系的理论。局 限于惯性参考系的时空理论称为狭义相对论
Chapter32 Relativity In fact, Einstein gives the correct laws of motion for any particle. This doesnt mean Newton was wrong, his equations are contained within the relatiⅳ istic(相对论 A)equations. For particles moving at slow speeds (very much less than the speed of light), the differences between einstein's laws of motion and those derived (导出) by Newton are tiny(微小的) Because most of us have little experience with objects moving at speeds near the speed of light einsteins predictions may seem strange. However, many years of high energy physics experiments have thoroughly tested Einstein's theory and shown that it fits all results to date
Because most of us have little experience with objects moving at speeds near the speed of light, Einstein‘s predictions may seem strange. However, many years of high energy physics experiments have thoroughly tested Einstein’s theory and shown that it fits all results to date. In fact, Einstein gives the correct laws of motion for any particle. This doesn‘t mean Newton was wrong, his equations are contained within the relativistic（相对论 的） equations. For particles moving at slow speeds (very much less than the speed of light), the differences between Einstein’s laws of motion and those derived （导出） by Newton are tiny（微小的）
