<p>Constantine: reduced exaggeration</p> <hr /> <div>The speed of light in a vacuum (postulated to be constant for all inertial observers by the [[Theory of Relativity|special theory of relativity]]) is, to nine significant figures, exactly 299,792,458 meters per second (approximately 186,282.3 miles per second). As the speed of light is used to define the [[SI]] meter, this is the value ''by definition''.<br /> <br /> The speed of light is slower in any medium which is not a vacuum, and varies from medium to medium. This variation gives rise to (as a result of [[quantum mechanics]], particularly the concept of a path of least action) the phenomenon of [[refraction]]. When a charged particle exceeds the speed of light in the medium in which it is travelling, it emits [[Cherenkov Radiation]].<br /> <br /> Since the speed of light in a vacuum is constant, it can be used to define distances as well. The distance that light travels in one year is known as a [[light-year]], which is about 6 million million (6x10&lt;sup&gt;12&lt;/sup&gt;) miles. For instance, the nearest large galaxy to our own [[Milky Way Galaxy]] is the [[Andromeda Galaxy]], which astronomers have measured to be about 2.5 million light years away, meaning visible light from the galaxy has taken 2.5 million years to reach Earth.<br /> <br /> The speed of light raises several minor questions for [[Young Earth Creationism|Young Earth Creationists]] including that of the [[starlight problem]].<br /> <br /> [[category: astronomy]]</div>

<p>Constantine: corrected date</p> <hr /> <div>{{stub}}<br /> <br /> '''Marcus Aurelius''' was the last of the [[Five Good Emperors]] of Rome. He lived from AD 121 to 180 and was a philosopher king who wrote many great works. His book ''Meditations'' emphasized one's duty. Marcus Aurelius should have thought more about his successor, however, because his death marked the end of the [[Pax Romana]].<br /> <br /> [[Category:Roman emperors]]</div>

<p>Constantine: spelling</p> <hr /> <div>'''Demonization''' is when a [[demagogue]], or group of demagogues, paints their ideological enemies or [[scapegoats]] in terms intended to render them as irredeemably evil and fit only for destruction, which is usually presented as 'self-defense'. Possibly the best-known example of demonization in the 20th century was the [[Nazi]]s' demonization of [[Jews]], which played off of existing [[antisemitism]] for political gain and eventually led to the [[Holocaust]].<br /> <br /> == Advantages of demonization for an unscrupulous politician ==<br /> *Gives followers an easy target for all their pent-up frustration.<br /> <br /> *Distracts them from any real causes for their problems which you may not be able or willing to cure.<br /> <br /> *If the demonized group is a political rival, reduces the risk that followers will defect to the rivals' group.<br /> <br /> [[Category:Politics]]</div>
