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.

評分這個作者在物理科普屆很有名
評分最引人深思的就是兩個理論,一個是穿越迴過去,相對論提齣光速運動可以延緩時間從而達到未來的效果,超光速理論上的的確確可以迴到過去,但是那種現象是否存在曆史意義,現在的我們能否改變過去的曆史,改變以後是否能夠影響現在的我們,這可能是一個哲學問題,另一個是關於穿越時空的旅行,是否真的存在蟲洞邊緣的時光機,能把我們帶迴到彼此,那個時候我的鶴發是你的童顔,我整整度過瞭你的一個曾經
