- This image shows the Rio Parana in Argentina in spring and summer 2002. It was compiled from data collected by the MODIS sensor aboard the Terra satellite. MODIS was able to pick up the signature of a few fires in some of the images, shown as red dots or outlines. Rio Parana (running north-south through image center) appears brown from the sediment in the water, and eventually drains into the Delta del Parana and the Rio de la Plata Estuary. Where the Rio de la Plata empties into the Atlantic, the brown, sediment-filled river water mixes with clearer ocean water and creates swirls and cloudy formations. Visible in these image is Buenos Aires, the capital city of Argentina, located where the Rio Parana meets the Rio de la Plata. Higher resolutions of the image show just how big the city is. Another city visible in the image is Montevideo, located on the opposite side of the Rio de la Plata. Montevideo is the capital city of Uruguay. Higher resolutions of the image show how heavily cultivated this region of Argentina is � farmland is clearly recognizable by the square and rectangular patterns of vegetation on the land. Uruguay, on the other hand, is not so heavily cultivated.
- Pythagoras (plato.standford.edu)
Pythagoras, one of the most famous and controversial ancient Greek philosophers, lived from ca. 570 to ca. 490 BCE. He spent his early years on the island of Samos, off the coast of modern Turkey. At the age of forty, however, he emigrated to the city of Croton in southern Italy and most of his philosophical activity occurred there. Pythagoras wrote nothing, nor were there any detailed accounts of his thought written by contemporaries. By the first centuries BCE, moreover, it became fashionable to present Pythagoras in a largely unhistorical fashion as a semi-divine figure, who originated all that was true in the Greek philosophical tradition, including many of Plato’s and Aristotle’s mature ideas. A number of treatises were forged in the name of Pythagoras and other Pythagoreans in order to support this view. See the entry on Pythagoreanism.
