The wave-particle duality is arguably one of the most intriguing concepts of quantum mechanics. Depending on the circumstances of the observation, a fundamental particle–like an electron–shows either wave- or particle-like behavior. One typical wave phenomenon is interference, where crests and troughs of two or more... click to read more

Under normal conditions, some materials are naturally better at conducting electricity than others. By applying high enough pressure, some materials that normally block the flow of electricity, like sulfur, can become conductors better than copper or gold. A wire of such "superconductor" could theoretically deliver... click to read more
