内容简介
相对论是关于时空和引力的基本理论,主要由爱因斯坦创立。它分为狭义相对论和广义相对论两部分。狭义相对论部分:爱因斯坦抛弃牛顿经典力学中的 时空观念,以麦克斯韦的“光速不变原理”为狭义相对论的立论根基。据此导出一系列既神奇怪异又激动人心的推论:运动的时钟会走慢;运动的量尺会缩短;运动的物体质量会增大;质量和能量是等价的,遵循质能关系式E=MC2,可以相互转化;质量守恒定律和能量守恒定律失去独立性,两者结合一起形成“质-能守恒定律”;等等。以上推论的结果虽然无一例外地得到了实验事实所证实,但只有在高速运动时,相对论效应才明显,而通常情况下,物体的运动速度都远小于光速,因而其效应极其微弱,因此,狭义相对论与经典力学推出的结果几乎趋于一致。但趋于一致并不表示等同,因此经典力学充其量只能算是相对论力学在低速情况下的近似,这就是狭义相对论的要旨。广义相对论部分广义相对论立论过程实质上就是爱因斯坦版的引力理论取代牛顿版的引力理论的过程。爱因斯坦发现,八大行星之所以在太阳周围绕圈圈,苹果之所以落地而不飞向太空深处均受制于时空环境,非万有引力所为。所谓万有引力其实是由时间和空间的结构本身特点而产生的几何效应。这就是爱因斯坦版的引力理论本质。爱因斯坦借助黎曼几何学,巧妙地使物理学几何化,几何学物理化,并于1915年完成了爱因斯坦场方程和自由质点运动方程,从而圆满地实现了物质的质量和能量是如何使时空发生弯曲,弯曲的时空又如何决定着物质在其中的运动。这就是广义相对论的真谛。
    
作者简介
陈昌康,1938年出生于福建省连江县定海小渔村。1961年7月毕业于厦门大学化学系物理化学专业,同年8月分配至福安农业专科学校工作,讲授物理、化学课程。

全国高考恢复后,于1978年3月调入武夷学院(原南平师专)任教,主讲物理化学和无机化学课程。1985年任化学系主任,1986年评为副教授。

在职期间,除负责教学和行政工作外,还承担了一定的科研任务,主攻农副产品深加工和环境保护课题,在有关学术刊物上发表科研论文十多篇,着有《怎样做好化学实验》《21世纪新能源》等书。

1998年退休,但退而不休,为发挥余热,至今仍忙碌于科学百花园中,采花酿蜜,乐此不疲科。
