LVX System of Companies is the inventor of Visible Light Communication (VLC) and Light Fidelity (Li-Fi) market.
 The LVX system is a collection of LED light bulbs and specialized equipment which allow the transmission of data through light photons- pulse width modulation (PWM) of the LED.
 The current speed at which the data is able to be transmitted is 3 Mbit/s.
 The goal of the LVX system is to free up wireless Wi-Fi spectrum which LVX asserts can be quite congested in some business areas.
 The 3 Mbit/s speed is slower than existing Wi-Fi technology, but the company is working on an improved LED which will be able to match the speeds of current Wi-Fi networks.
 The lights also have ability to transmit any specific colour along the spectrum.
 Because the lights are also communication devices, they could be directed through the LVX network to turn a certain colour to lead the way out of a building during emergencies or to a specific office.
 As well, lights could be directed to turn on and off as an energy savings measure.
 The communication and networking capabilities are marketed as an add-on or "bonus" to the energy savings and maintenance inherited by LED lights in general as compared to fluorescent or incandescent light bulbs.
 LVX sells maintenance contracts in which LVX will be responsible for the 24/7 maintenance of the lights.
The Book of Souls is the sixteenth studio album by English heavy metal band Iron Maiden, released on 4 September 2015.
 It is the band's first studio double album, and therefore also their longest to date, with a total length of 92 minutes.
 Its launch and supporting tour were delayed to allow vocalist Bruce Dickinson time to recover from the removal of a cancerous tumour in early 2015.
When using the term 'the speed of light' it is sometimes necessary to make the distinction between its one-way speed and its two-way speed.
 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 "two-way" speed of light) from the source to the detector and back again.
 Albert Einstein chose a synchronization convention (see Einstein synchronization) that made the one-way speed equal to the two-way speed.
 The constancy of the one-way speed in any given inertial frame is the basis of his special theory of relativity, although all experimentally verifiable predictions of this theory do not depend on that convention.
Length contraction is the phenomenon that a moving object's length is measured to be shorter than its proper length, which is the length as measured in the object's own rest frame.
 This contraction (more formally called Lorentz contraction or Lorentz–FitzGerald contraction after Hendrik Lorentz and George Francis FitzGerald) is usually only noticeable at a substantial fraction of the speed of light.
 Length contraction is only in the direction parallel to the direction in which the observed body is travelling.
 For standard objects, this effect is negligible at everyday speeds, and can be ignored for all regular purposes.
 Only at greater speeds, or for electron motion, does it become significant.
 At a speed of 13,400,000 m/s (30 million mph, 0.0447"c" ) contracted length is 99.9% of the length at rest; at a speed of 42,300,000 m/s (95 million mph, 0.141"c" ), the length is still 99%.
 As the magnitude of the velocity approaches the speed of light, the effect becomes dominant, as can be seen from the formula:
The lighthouse paradox is a situation in which the speed of light is apparently exceeded.
 Upon observation, it would seem that a lighthouse is able to shine light on one object and then, in a manner that is faster than the speed of light, shine light on another object.
 However this is not true, as the photons from the light source that are hitting object 1 are not traveling from object 1 to object 2, but rather, different photons are reflected off each object.
 Meaning, there is no movement of the "light beam" from one object to another, as though it were a single entity of matter, but a projection of many entities that reflect off of the different objects.
 The lighthouse paradox essentially proposes a situation which violates Einstein's theory of special relativity using superluminal signalling.
 In other words, a condition in which information or matter is traveling faster than the speed of light.
 Through careful analysis this paradox is resolved.
In Conway's Game of Life (and related cellular automata), the speed of light is a propagation rate across the grid of exactly one step (either horizontally, vertically or diagonally) per generation.
 In a single generation, a cell can only influence its nearest neighbours, and so the speed of light (by analogy with the speed of light in physics) is the maximum rate at which information can propagate.
 It is therefore an upper bound to the speed at which any pattern can move.
Kin Sang () is an at-grade MTR Light Rail stop located at Leung Wan Street in Tuen Mun District, near Kin Sang Shopping Centre in Kin Sang Estate.
 It began service on 23 September 1988 and belongs to Zone 3.
 It serves the Kin Sang Estate and nearby residential buildings.
The invariant speed or observer invariant speed is a speed which is measured to be the same in all reference frames by all observers.
 The invariance of the speed of light is one of the postulates of special relativity, and the terms "speed of light" and "invariant speed" are often considered synonymous.
 In non-relativistic classical mechanics, or Newtonian mechanics, finite invariant speed does not exist (the only invariant speed predicted by Newtonian mechanics is infinity).
"Speed of Light" is a song by the English heavy metal band Iron Maiden from their sixteenth studio album, "The Book of Souls".
 The song was released as a music video on 14 August 2015 and was also made available as a digital download and issued as a single-track CD exclusive to Best Buy in the US.
Relativistic rocket refers to any spacecraft that travels at a velocity close enough to light speed for relativistic effects to become significant.
 The meaning of "significant" is a matter of context, but generally speaking a velocity of at least 50% of the speed of light (0.5"c") is required.
 The Lorentz factor - also known as the "gamma" factor, γ, and present in the equations for time dilation, relativistic mass, and length contraction - is equal to 1.15 at 0.5"c".
 Above this speed special relativity is required to accurately describe motion, whereas below this speed sufficient accuracy is provided by Newtonian physics and the Tsiolkovsky rocket equation.
