具体描述
A fascinating exploration of the science of the impossible—from death rays and force fields to invisibility cloaks—revealing to what extent such technologies might be achievable decades or millennia into the future.
One hundred years ago, scientists would have said that lasers, televisions, and the atomic bomb were beyond the realm of physical possibility. In Physics of the Impossible , the renowned physicist Michio Kaku explores to what extent the technologies and devices of science fiction that are deemed equally impossible today might well become commonplace in the future.
From teleportation to telekinesis, Kaku uses the world of science fiction to explore the fundamentals—and the limits—of the laws of physics as we know them today. He ranks the impossible technologies by categories—Class I, II, and III, depending on when they might be achieved, within the next century, millennia, or perhaps never. In a compelling and thought-provoking narrative, he explains:
· How the science of optics and electromagnetism may one day enable us to bend light around an object, like a stream flowing around a boulder, making the object invisible to observers “downstream”
· How ramjet rockets, laser sails, antimatter engines, and nanorockets may one day take us to the nearby stars
· How telepathy and psychokinesis, once considered pseudoscience, may one day be possible using advances in MRI, computers, superconductivity, and nanotechnology
· Why a time machine is apparently consistent with the known laws of quantum physics, although it would take an unbelievably advanced civilization to actually build one
Kaku uses his discussion of each technology as a jumping-off point to explain the science behind it. An extraordinary scientific adventure, Physics of the Impossible takes readers on an unforgettable, mesmerizing journey into the world of science that both enlightens and entertains.

这个作者在物理科普届很有名
评分最引人深思的就是两个理论，一个是穿越回过去，相对论提出光速运动可以延缓时间从而达到未来的效果，超光速理论上的的确确可以回到过去，但是那种现象是否存在历史意义，现在的我们能否改变过去的历史，改变以后是否能够影响现在的我们，这可能是一个哲学问题，另一个是关于穿越时空的旅行，是否真的存在虫洞边缘的时光机，能把我们带回到彼此，那个时候我的鹤发是你的童颜，我整整度过了你的一个曾经
评分打算捐給學校圖書館
评分Fabulous Never thought Physics could be so interesting until I began to realize it's the key to answer my questions. I should've paid more attention in high school physics class....
