The Quantum Hall Effect
... particles that roam around these systems carry a fraction of the charge of the electron, as if the electron has split itself into several pieces. Yet this occurs despite the fact that the electron is (and remains!) an indivisible constituent of matter. In fact, it is not just the charge of the elect ...

... The velocity of light is not an absolute velocity in space, but a velocity relative to the ether. It is, in principle, no more a difficulty than the existence of a determinate velocity of sound relative to air. The velocity of light as measured by any observer should depend on that observer’s own ve ...
