In this expansive, illuminating journey through the mind, theoretical physicist Kaku (Physics of the Future) explores fantastical realms of science fiction that may soon become our reality. His futurist framework merges physics with neuroscience to model how our brains construct the future, and is loosely applied to demonstrations that “show proof-of-principle” in accomplishing what was previously fictional: that minds can be read, memories can be digitally stored, and intelligences can be improved to great extents. The discussion, while heavily scientific, is engaging, clear, and replete with cinematic references. Kaku’s claims, however, often lack generalizability: his points about human thought are derived from research studies and patterns that emerge from discrete areas of analysis under highly sophisticated technological surveillance. The place of these esoteric conclusions in the nuanced processes of our daily life is rarely explained. Likewise, each issue raised, while fascinating, is equally fleeting: topics skip from telepathy helmets to cell phone MRIs in just over a page. Legal and ethical complications, too, arise with each predicted advance, though aren’t given the attention they demand. These new mental frontiers make for captivating reading, yet Kaku’s optimism and enthusiasm provides cover for what are mostly overhyped claims. Agent: Stuart Krichevsky.

Having written the enthusiastic but strictly science-based Physics of the Impossible (2008) and Physics of the Future (2011), Kaku (Theoretical Physics/City Univ. of New York) turns his attention to the human mind with equally satisfying results. Aware that predictions limited to a lifetime are usually wrong--where are the flying cars, cancer cures and Mars colonies foretold in the 1950s?--the author expands his forecasts to the next few centuries. He has no trouble foreseeing telepathy, telekinesis, intelligence pills, artificial memories and mind control. He agrees that centuries of research by physicians and neuroscientists has borne fruit, but he boasts that the end of the 20th century saw his own profession, physics, produce spectacular advances, with more to come. Acronymic high-tech machines (fMRI, PET, ECOG, DTI) allow researchers to watch the brain reason, see, remember and deliver instructions. Telepathy is no longer a fantasy since scanners can already detect, if crudely, what a subject is thinking, and genetics and biochemistry now allow researchers to alter memories and increase intelligence in animals. Direct electrical stimulation of distinct brain regions has changed behavior, awakened comatose patients, relieved depression, and produced out-of-body and religious experiences. Similar to the human genome program, massive research efforts in the United States and Europe to reverse-engineer the brain have the potential to vastly increase human potential as well as relieve disease and injury. "[W]e should treasure the consciousness that is found on the Earth," writes the author. "It is the highest form of complexity known in the universe, and probably the rarest." Kaku is not shy about quoting science-fiction movies and TV (he has seen them all). Despite going off the deep end musing about phenomena such as isolated consciousness spreading throughout the universe, he delivers ingenious predictions extrapolated from good research already in progress.

Having wowed us with New York Times best sellers like Physics of the Future, CUNY physics professor Kaku takes us into the new neuroscience, showing us that recording memories and videotaping our dreams aren't sf fantasies but reality. And soon we might be able to upload our brains to a computer. With an eight-city tour.
