Slow light — is the literal slowing of the speed of light. It is the propagation of an optical pulse or other modulation of an optical carrier at a very low group velocity. The term is usually only applied when the velocity is at least hundreds of times… … Wikipedia
Speed of light — The speed of light in the vacuum of free space is an important physical constant usually denoted by the letter c . [NIST and BIPM practice is to use c 0 for the speed of light in vacuum in accord with international standard ISO 31 5. See… … Wikipedia
Slow zone — A slow zone, in America, is an area where a train is forced to slow down for either structural, construction, power, signal, or track problems. Slow zones limit a train to about 10 35 MPH. Notification to train crews is referred to as a slow… … Wikipedia
Railway signal — Not to be confused with Railway signalling. A signal is a mechanical or electrical device erected beside a railway line to pass information relating to the state of the line ahead to train/engine drivers. The driver interprets the signal s… … Wikipedia

One-way speed of light — The one way speed of light from a source to a detector, cannot be measured independently of a convention as to how to synchronize the clocks at the source and the detector. What can however be experimentally measured is the round trip speed (or… … Wikipedia
Variable speed of light — The variable speed of light (VSL) concept states that the speed of light in a vacuum, usually denoted by c , may not be constant in some cases. In most situations in condensed matter physics when light is traveling through a medium, it… … Wikipedia
Electronic speed control — An electronic speed control or ESC is a device mounted onboard an electrically powered radio control model in order to vary its drive motor s speed, its direction and even to act as a dynamic brake in certain controllers.An ESC can be a stand… … Wikipedia
