One plus one equals 3 is another Science fiction adventure exploring the realm of Quantum Science and theory. Quantum mechanics is the body of scientific laws that describe the wacky behavior of photons, electrons and the other particles that make up the universe. However, when you try to join quantum mechanics to any other major theory in physics, like Einstein's general theory of relativity, it doesn't work. Quantum mechanics may be correct, but it's a total mystery as to how it fits in with the rest of physics.
