http://www.philosophy-index.com/philosophy/mind/mind-body.php The Mind-Body Problem The mind-body problem is an ongoing problem in the philosophy of mind and in metaphysics, concerning the nature of the relationship between the mind, or conciousness, and the physical world. The mind-body problems asks a number of questions: Are the mind and body separate substances or elements of the same substance? What is their relationship to each other? What is conciousness? And how can conciousness arise out of ordinary matter? There are a number of responses to the mind-body problem, though none have universal acceptance. A number of these positions are outlined below: Dualism , the position that the mind is essentially not physical, and exists separately from the body. Dualism comes in various forms: Interactionism , which states that the mind and body have causal interaction. Occasionalism , which states the apparently causal links between mind and body are actually divine interven...

A photon is an elementary particle , the quantum of all forms of electromagnetic radiation including light . It is the force carrier for electromagnetic force , even when static via virtual photons . The photon has zero rest mass and as a result, the interactions of this force with matter at long distance are observable at the microscopic and macroscopic levels. Like all elementary particles, photons are currently best explained by quantum mechanics and exhibit wave–particle duality , exhibiting properties of both waves and particles . For example, a single photon may be refracted by a lens and exhibit wave interference with itself, and it can behave as a particle with definite and finite measurable position and momentum . The photon's wave and quanta qualities are two observabl...

Jupiter Important to the ancient Babylonians, the brilliant planet Jupiter ruled the night sky and mapped out the Zodiacal constellations. IN ROMAN AND GREEK MYTHOLOGY the god Jupiter was accepted as the most powerful and capricious ruler of the heavens; no wonder ancient astronomers gave the same name to the planet that year after year so brilliantly rules the night sky. After the Sun and the Moon, Jupiter is, indeed, the most spectacular object in the sky. Although Venus is at times brighter it cannot ride the midnight sky as does Jupiter. Today's astronomers acknowledge Jupiter as being perhaps the most important planet of the Solar System. It is the largest and most massive. After the Sun-the star about which all bodies of the Solar System revolve -Jupiter contains two-thirds of the matter in the Solar System. Orbiting the Sun at an average distance of 779 million km (484 million mi.), Jupiter is some 5.2 times as far away as Earth. Cuneiforms of the Babylonian e...

HOW LONG DOES IT TAKE SUNLIGHT TO REACH THE EARTH? 8 minutes and 20 seconds Here’s the math. We orbit the Sun at a distance of about 150 million km. Light moves at 300,000 kilometers/second. Divide these and you get 500 seconds, or 8 minutes and 20 seconds. This is an average number. Remember, the Earth follows an elliptical orbit around the Sun, ranging from 147 million to 152 million km. At its closest point, sunlight only takes 490 seconds to reach Earth. And then at the most distant point, it takes 507 seconds for sunlight to make the journey. How fast does light travel from the Sun to each of the planets? Light travels at a speed of 299,792 kilometers per second; 186,287 miles per second. It takes 499.0 seconds for light to travel from the Sun to the Earth, a distance called 1 Astronomical Unit. below I list the light travel times from the Sun to each planet: Planet Distance in AU Travel time ....................................................

La première observation connue d'Io est réalisée par Galilée le 7 janvier 1610. La découverte d'Io et des autres satellites galiléens est publiée par l'astronome dans son ouvrage Sidereus Nuncius en mars 1610. En 1614, dans son Mundus Jovialis, Simon Marius prétend avoir découvert ces objets en 1609, une semaine avant Galilée. Quelle que soit la validité des propos de Marius (Galilée, par exemple, le considère comme un imposteur et un plagiaire), Galilée est considéré comme le découvreur d'Io, ayant publié cette découverte le premier. Simon Marius ( Latinized from German Simon Mayr ; January 20, 1573 – January 5, 1625) was a German astronomer . He was born in Gunzenhausen , near Nuremberg , but he spent most of his life in the city of Ansbach . In 1614 Marius published his work Mundus Iovialis describing the planet Jupiter and its moons. Here he claimed to have discovered the planet's four major moons some days befor...

Metric system Metric system, international decimal system of weights and measures, based on the metre for length and the kilogram for mass, that was adopted in France in 1795 and is now used officially in almost all countries. The French Revolution of 1789 provided an opportunity to pursue the frequently discussed idea of replacing the confusing welter of thousands of traditional units of measure with a rational system based on multiples of 10. In 1791 the French National Assembly directed the French Academy of Sciences to address the chaotic state of French weights and measures. It was decided that the new system would be based on a natural physical unit to ensure immutability. The academy settled on the length of 1/10,000,000 of a quadrant of a great circle of Earth, measured around the poles of the meridian passing through Paris. An arduous six-year survey led by such luminaries as Jean Delambre, Jacques-Dominique Cassini, Pierre Mechain, Adrien-Marie Legendre, and others to d...

http://www.newworldencyclopedia.org/entry/Intelligent_design Intelligent design philosophy Intelligent design Previous (Intelligence test) Next (Intension and Extension) Creation of Light.png Intelligent design (ID) is the view that it is possible to infer from empirical evidence that "certain features of the universe and of living things are best explained by an intelligent cause, not an undirected process such as natural selection" [1] Intelligent design cannot be inferred from complexity alone, since complex patterns often happen by chance. ID focuses on just those sorts of complex patterns that in human experience are produced by a mind that conceives and executes a plan. According to adherents, intelligent design can be detected in the natural laws and structure of the cosmos; it also can be detected in at least some features of living things. Greater clarity on the topic may be gained from a discussion of what ID is not considered to be by its leading theorist...
