![]() ![]() ![]() William Thomson Kelvin (1824–1907), a mathematical physicist and creator of the Kelvin scale said publicly that “heavier than air” flying machines were impossible. The concept of impossibility Īccording to Kaku, technological advances that we take for granted today were declared impossible 150 years ago. With each discussion of science fiction technology topics he also "explains the hurdles to realizing these science fiction concepts as reality". ![]() ![]() The cover of his book depicts a TARDIS, a device used in the British science fiction television show Doctor Who to travel in space and time, in its disguise as a police box, continuously passing through a time loop. The topic of Star Trek "phasers" becomes a lesson on how lasers work and how laser-based research is conducted. The topic of invisibility becomes a discussion on why the speed of light is slower in water than in vacuum, that electromagnetism is similar to ripples in a pond, and Kaku discusses newly developed composite materials. Kaku uses discussion of speculative technologies to introduce topics of fundamental physics to the reader. Physics of the Impossible: A Scientific Exploration Into the World of Phasers, Force Fields, Teleportation, and Time Travel is a book by theoretical physicist Michio Kaku. ![]()
