The refractive index (or index of refraction) of a medium is a measure of how much the speed of light (or other waves such as sound waves) is reduced inside the medium. For example, typical soda-lime glass has a refractive index close to 1.5, which means that in glass, light travels...

Relativistic beaming(also known asDoppler beaming, Doppler boosting,or theheadlight effect) is the process by whichrelativistic effectsmodify the apparent luminosity of emitting matter that is moving at speeds close to thespeed of light. In an astronomical context, relativistic beaming commonly occurs i...
Speculation is important for forecasting; it's also fun. Speculation is usually conveyed in two forms: in the form of an argument, or encapsulated i…
This meant that the greater the distance between any two galaxies, the greater their relative speed of separation. If interpreted that way, Hubble's measurements on 46 galaxies lead to a value for the Hubble constant of 500 km/s/Mpc, which is much higher than the currently accepted values ...
particularly in light of the tremendous advances made in the field over recent years in terms of both quality and speed. Furthermore, there exist a variety of future research directions worth pursuing. For instance, we only considered references corresponding to web pages, but Wikipedia also cites...
For example, for ground stations atlatitudesofφ=±45° on the samemeridianas the satellite, the one-way delay can be computed by using thecosine rule, given the above derived geostationary orbital radiusr, theEarth's radiusRand thespeed of lightc, as ...
There is precious little that is natural … in any film. You distort speed if you want to show things like plants growing, or look in detail at the way an animal moves. You distort light levels. You distort distribution, in the sense that you see dozens of different species in a jungle...
A student of the great scholars Yu Yue and Zhang Taiyan, Song had been to Japan and observed the stunning effect of the kana syllabaries and Western learning there. This galvanized him into activity on a number of fronts, one of the most important being reform of the script. While Song...
