Two superrealities are superfluidity and superconductivity. Both are the studies of condensed-matter physics which investigates the thermal, elastic, electrical, magnetic, and optical properties of solids and liquids. The study of solid-state physics had given us the transistor and integrated circuitry of the microchips which in turn given us the digital revolution of supercomputers and cell phones. The other study of condensed-matter is the liquid state: liquid crystals (flat screen computer monitors), and at very low temperature near absolute zero, the study of quantum liquid. Macroscopic quantum liquid has the emergent property of superfluidity, a completely frictionless flow of zero viscosity; and the property of superconductivity, which allows electrons to flow without any resistance in conductors. Since both properties can only arise at extremely low temperature, indicates that these might be related to the thermal property of zero entropy at absolute zero. Time independence: [∂E(g)]²=[∂F(a)×∂r(a)]·[∂F(b)×∂r(b)] and Mass independence: ¶a(t)·¶r(t)=c² |
