Light Cycles became well known in popular culture as one of the first mainstream cinematic appearances of a sports bike [citation needed], and have been called symbols of futurism and posthumanism. In an analysis, author Esperanza Miyake interpreted the Light Cycles of the original Tron as representations of male power: only men get the chance ...
The rotation of the earth around its axis produces 24 hour changes in light (day) and dark (night) cycles on earth. The length of the light and dark in each phase varies across the seasons due to the tilt of the earth around its axis. The photoperiod defines the length of the light, for example a summer day the length of light could be 16 hours ...

Beam of sun light inside the cavity of Rocca ill'Abissu at Fondachelli-Fantina, Sicily. The speed of light in vacuum is defined to be exactly 299 792 458 m/s (approximately 186,282 miles per second). The fixed value of the speed of light in SI units results from the fact that the metre is now defined in terms of the speed of light.
The astronomers who first noted the dimming of Betelgeuse, Villanova University astronomers Richard Wasatonic and Edward Guinan, and amateur Thomas Calderwood, theorize that a coincidence of a normal 5.9 year light-cycle minimum and a deeper-than-normal 425 day period are the driving factors. [61]

The Calvin cycle is present in all photosynthetic eukaryotes and also many ...
Ecological light pollution [1] is the effect of artificial light on individual organisms and on the structure of ecosystems as a whole.. The effect that artificial light has upon organisms is highly variable, [2] and ranges from beneficial (e.g. increased ability for predator species to observe prey) to immediately fatal (e.g. moths that are attracted to incandescent lanterns and are killed by ...
