这本书内容确实是不错啊,没用很多的公式来推导为什么E=mc2,但是对于一个对理科一窍不通甚至于自我屏蔽的人来说,这本书仍然不太好懂懂。 于是这本书吸引我的地方就和里面的公式和方程无关了,这本书让我产生了对宇宙的无限的思考,人类对自然现象以及宇宙时空的探索的欲望是... (展开) ...
把手按在桌子上,你能感到桌子的抗拒,这种抗拒力本质上和相同磁极互相排斥如出一辙;一辆半光速行驶的列车,时间到底变慢了多少?只要勾股定理便可推算出来。都说运动是相对的而为啥光速偏偏绝对?爱因斯坦想不通,相对论便应此纠结而生。如果在一个无限远的地平面上,同时释放一个铁球和一束与地面平行的光,铁球会和光...

A few decades later and armed withEinstein’sfamous E = mc2, which confirmed anything that has mass must have an equivalent amount of energy, 1920s British astronomers proposed that the sun was actually converting its mass into energy. However, instead of a furnace that converts wood and coal...
Physicists like to use the term “Elegant” to describe the greatest discoveries such as Newton’s gravity, Relativity both Special (E = MC2) and General and even Heisenberg’s microscope mind experiment in quantum. They are called that because they are simple (for them) explanations of very ...
Yet a supply from nuclear fusion could provide massive amounts of energy from a very small footprint. With the E=mc2 formula revealing the possibilities of it, and our already understood knowledge of the scale of difference between energy production from nuclear fission shown in theatomic bombto...
我们应该非常真切地感受到E=mc2是生命的种子。如果没有它,太阳不会燃烧,黑暗会永久笼罩大地。 (查看原文) Satoru 2024-01-31 20:22:52 —— 引自章节:第五章 为什么E=mc2 ? 77 > 我来写笔记 > Why Does E=mc2 and Why Should We Care? 作者: Cox, Brian; Forshaw, Jeff isbn: 140744929X 书...
