This sentence is false. Is this sentence true? If it is true that the sentence is false then the sentence is true. If it is false that the sentence is false then the sentence is true. This is a logical contradiction. The sentence can not be both true & false simultaneously. The sentence must be true or false. This begins our journey into the nature of the paradox. A paradox is an absurd truth that derives a repugnant conclusion from an unquestionable set of premises. The listener will usually agree with the arguments supporting the conclusion but be unwilling to accept the final inference. To resolve a paradox, we must do one of four things: ignore it, distort it, reject it, or accept it. This thought provoking book, Space, Time, & Reality, seeks to probe the depths of the human mind by leveraging the power of the paradox. This is a book of questions...not answers, & is intended for those who accept or reject & not ignore or distort.

NATIONAL BESTSELLER • The renowned theoretical physicist and national bestselling author of The God Equation details the developments in computer technology, artificial intelligence, medicine, space travel, and more, that are poised to happen over the next century. “Mind-bending…. [An] alternately fascinating and frightening book.” —San Francisco Chronicle Space elevators. Internet-enabled contact lenses. Cars that fly by floating on magnetic fields. This is the stuff of science fiction—it’s also daily life in the year 2100. Renowned theoretical physicist Michio Kaku considers how these inventions will affect the world economy, addressing the key questions: Who will have jobs? Which nations will prosper? Kaku interviews three hundred of the world’s top scientists—working in their labs on astonishing prototypes. He also takes into account the rigorous scientific principles that regulate how quickly, how safely, and how far technologies can advance. In Physics of the Future, Kaku forecasts a century of earthshaking advances in technology that could make even the last centuries’ leaps and bounds seem insignificant.

"The science-fiction genre known as steampunk juxtaposes futuristic technologies with Victorian settings. This fantasy is becoming reality at the intersection of two scientific fields-twenty-first-century quantum physics and nineteenth-century thermodynamics, or the study of energy-in a discipline known as quantum steampunk"--

Learn about physics with fun projects and experiments Created in partnership with Thames & Kosmos, Fun Physics Projects for Tomorrow's Rocket Scientists introduces you to essential physics concepts through do-it-yourself projects that you can then use to perform experiments. Experience the thrill of scientific discovery when you observe the physics of motion, including constant speed, acceleration, and free fall, through your own experiments. All of the projects use inexpensive, readily available materials and software. No experience required! Chapters feature: Things You'll Need--lists of all the components and equipment required for each project Be Careful--important safety tips Famous Scientists--introductions to people who've made significant contributions to our understanding of physics Online Videos--link to the author's demonstrations of the projects Step-by-step projects include: Constant-speed vehicle Uniform acceleration fan car Tennis ball cannon to investigate speed and study free fall Trebuchet for observing the force of weight Projectile-motion catapult Water rocket to demonstrate Newton's Laws of Motion Mousetrap-powered car that displays energy transformations Model rocket engine to calculate momentum and impulse Rocket launch ignition system and launch pad Cool model rockets that demonstrate acceleration, speed, and altitude
