world. As such, this revolution was primarily an epistemological revolution it changed man's thought process. It was an intellectual revolution a revolution in human knowledge. Even more than Renaissance scholars who discovered man and Nature, the scientific revolutionaries attempted to understand and explain man and the natural world. Thinkers such as the Polish astronomer Nicholas Copernicus(14731543), the French philosopher René Descartes(15961650) and the British mathematician Isaac Newton(16421727) overturned the authority of the Middle Ages and the classical world. And by authority I am not referring specifically to that of the Church the demise of its authority was already well under way even before the Lutheran Reformation had begun. The authority I am speaking of is intellectual in nature and consisted of the triad of Aristotle(384322) and Ptolemy (c.90168).
Tallinna Tööstushariduskeskus Saturn Referaat Tallinn 2014 Sissejuhatus Saturn is one of the most interesting planets in the solar system. It is the sixth planet in the solar system, and is most famous for its stunning array of rings. It is a very easy planet to pick out in the sky because it is one of the brightest lights in the shy. It also has a very faint greenish color that makes it stand out from the rest of the objects in the sky ("Astronomy for Kids"). Saturn is the second largest planet in the solar system, Jupiter being the only planet that is bigger. It also has at least eighteen moons, more than any other planet in the solar system. There have been three voyages to this extraordinary planet, and one is still in process today. The Pioneer II traveled to Saturn in September of 1979, the Voyager missions took place in the 1980's and the Cassini probe began it's voyage in Octo
The Cataclysmic Death of Stars Republished from the pages of National Geographic magazine Written by Ron Cowen March 2007 Ever since he was a teenager, Stan Woosley has had a love for chemical elements and a fondness for blowing things up. Growing up in the late 1950s in Texas, "I did everything you could do with potassium nitrate, perchlorate, and permanganate, mixed with a lot of other things," he says. "If you mixed potassium nitrate with sulfur and charcoal, you got gunpowder. If you mixed it with sugar, you got a lot of smoke and a nice pink fire." He tested his explosive concoctions on a Fort Worth golf course: "I screwed the jar down tight and ran like hell." "kaboomWoosley", now an astronomer at the University of California at Santa Cruz, has graduated to bigger explosions--much bigger. Woosley studies some of the most powerful explosions since the birth of the universe: supernovae, the violent deaths of stars. The universe twinkles with these cataclysms. They happen every sec
Early Life • Born on March 14, 1879 in Ulm, Württemberg, Germany.(Galenet) • Although Jewish, Albert Einstein attended a Catholic School. (Galenet) • At only age 15, Einstein completed his first scientific work, “The Investigation of the State of Aether in Magnetic field.” (Galenet) • Never completed high school in hopes of applying directly to ETH Zurich. (Fara, EBSCOHOST) Marriage Life • Married to Mileva Marić in January 6, 1903. (Galenet) • Has two sons, Hans Albert Einstein, and Eduard Einstein. (Galenet) • Divorced Mileva on February 14, 1919. (Galenet) • Married Elsa Löwenthal on June 2, 1919 shortly after divorcing his first wife. (Galenet) Miracle Year • Wrote 4 papers in 1905, and all them are regarded as major achievements. – The Photoelectric Effect – The Brownian Motion – The Theory of Relativity – E=MC2 The Photoelectric Effect • Einstein hypo

Derive vorticity transport equation in the plane and in the axisymmetric cases? 1.1 Vorticity is equal to the curl of the flow velocity. Vorticity is the tendency for elements of the fluid to "spin." Mathematically, vorticity is a vector field and is defined as the curl of the velocity field. w = curl (u ) = × u 1.2 Vorticity transport equation on the plane From the Navier-Stokes equation u 1 + u ( u ) = - p + g + v 2 u t We derive equation for two dimentional case on x-y plane (in the absence of gravi

However, he failed to explain why planets moved that way. Few years after Kepler, the telescope was invented. Galileo used throroughly his telescope and made important discoveries (new pieces to the puzzle): Description of the moon, The moon of Jupiter Sunspots The phases of Venus. Galileo’s discoveries gave strong evidence for the heliocentric view of the world. His discoveries led him to troubles with the Church (‘Yet it turns…’) Later, Newton (1687) introduced his laws of motion to explain the movement of the planets. A New (Newtonian) Worldview (and its variations) will dominate until around 1900. Scientific Revolutions Thomas Kuhn, The Structure of Scientific Revolutions (1962) Science is not a linear accumulation of accepted facts. Periods of accumulation (Normal Science) are interrupted by Revolutions (Revolutionary Science). In normal science, scientists work within a paradigm, i.e
Philosophy of Language Philosophy of Language: a Contemporary Introduction introduces the student to the main issues and theories in twentieth and twenty-first-century phi- losophy of language, focusing specifically on linguistic phenomena. Topics are structured in four parts in the book. Part I, Reference and Referring, includes topics such as Russell's Theory of Descriptions, Donnellan's distinction, problems of anaphora, the description theory of proper names, Searle's cluster theory, and the causalhistorical theory. Part II, Theories of Meaning, surveys the competing theories of linguistic mean- ing and compares their various advantages and liabilities. Part III, Pragmatics and Speech Acts, introduces the basic concepts of linguistic pragmatics, includes a detailed discussion of the problem of indirect force and surveys approaches to metaphor. Part IV, new to this edition, examines the four theories of metaphor. Features of Philosophy of Language include: · new c
