Physics of the Impossible

In 'Physics of the Impossible,' Michio Kaku delves into the world of science fiction to explore the possibilities and limitations of various technologies such as teleportation, force fields, invisibility, and time travel.

Kaku categorizes these technologies into three classes based on their potential for realization: Class I (achievable within the next century), Class II (achievable within the next few millennia), and Class III (possibly never achievable unless fundamental laws of physics change).

The book discusses how advances in fields like optics, electromagnetism, MRI, computers, superconductivity, and nanotechnology could make some of these science fiction concepts a reality.

Kaku also explains the scientific principles behind these technologies, making the book an enlightening and entertaining journey into the future of science.
