Information:  - A river is a natural flowing watercourse, usually freshwater, flowing towards an ocean, sea, lake or another river. In some cases a river flows into the ground and becomes dry at the end of its course without reaching another body of water. Small rivers can be referred to using names such as stream, creek, brook, rivulet, and rill. There are no official definitions for the generic term river as applied to geographic features, although in some countries or communities a stream is defined by its size. Many names for small rivers are specific to geographic location; examples are "run" in some parts of the United States, "burn" in Scotland and northeast England, and "beck" in northern England. Sometimes a river is defined as being larger than a creek, but not always: the language is vague.  - "Main Stem" is 1942 instrumental by Duke Ellington and His Famous Orchestra. Although recorded in 1942, the single would not be released until 1944 where it was Duke Ellington's last of four number one's on the Harlem Hit Parade. "Main Stem" also peaked at number twenty on the pop chart.  - The Red River , or sometimes the Red River of the South , is a major tributary of the Mississippi and Atchafalaya rivers in the southern United States of America . The river was named for the red - bed country of its watershed . It is one of several rivers with that name . `` The Mexicans and Indians on the borders of Mexico are in the habit of calling any river , the waters of which have a red appearance , ' Rio Colorado ' , or Red river '' , observed R.B. Marcy in 1853 . The Red River formed part of the US - Mexico border from the Adams - Onís Treaty ( in force 1821 ) until the Texas Annexation and the Treaty of Guadalupe Hidalgo . The Red River is the second - largest river basin in the southern Great Plains . It rises in two branches ( forks ) in the Texas Panhandle and flows east , where it acts as the border between the states of Texas and Oklahoma . It forms a short border between Texas and Arkansas before entering Arkansas , turning south near Fulton , Arkansas and flowing into Louisiana , where it flows into the Atchafalaya River . The total length of the river is 1,360 miles ( 2,190 km ) , with a mean flow of over 57,000 cubic feet per second ( 1,600 m3 / s ) at the mouth .  - A tributary or affluent is a stream or river that flows into a larger stream or main stem (or parent) river or a lake. A tributary does not flow directly into a sea or ocean. Tributaries and the main stem river drain the surrounding drainage basin of its surface water and groundwater, leading the water out into an ocean.  - A drainage basin or catchment basin is an extent or an area of land where all surface water from rain, melting snow, or ice converges to a single point at a lower elevation, usually the exit of the basin, where the waters join another body of water, such as a river, lake, reservoir, estuary, wetland, sea, or ocean. Thus if a tributary stream joins a brook that in turn joins a small river which is a tributary of a larger river, there is a series of successively larger (and lower elevation) drainage basins. For instance, the Missouri and Ohio rivers are within their own drainage basins and also within the drainage basin of the Mississippi River.

*Question*
Information:  - Epicurus (or  "ally, comrade"; 341270 BC) was an ancient Greek philosopher as well as the founder of the school of philosophy called Epicureanism. Only a few fragments and letters of Epicurus's 300 written works remain. Much of what is known about Epicurean philosophy derives from later followers and commentators.  - Epicureanism is a system of philosophy based upon the teachings of the ancient Greek philosopher Epicurus, founded around 307 BC. Epicurus was an atomic materialist, following in the steps of Democritus. His materialism led him to a general attack on superstition and divine intervention. Following Aristippusabout whom very little is knownEpicurus believed that what he called "pleasure" was the greatest good, but that the way to attain such pleasure was to live modestly, to gain knowledge of the workings of the world, and to limit one's desires. This would lead one to attain a state of tranquility ("ataraxia") and freedom from fear as well as an absence of bodily pain ("aponia"). The combination of these two states constitutes happiness in its highest form. Although Epicureanism is a form of hedonism insofar as it declares pleasure to be its sole intrinsic goal, the concept that the absence of pain and fear constitutes the greatest pleasure, and its advocacy of a simple life, make it very different from "hedonism" as it is colloquially understood.  - Themista of Lampsacus , the wife of Leonteus , was a student of Epicurus , early in the 3rd century BCE . Epicurus ' school was unusual in the 3rd century , in that it allowed women to attend , and we also hear of Leontion attending Epicurus ' school around the same time . Cicero ridicules Epicurus for writing `` countless volumes in praise of Themista , '' instead of more worthy men such as Miltiades , Themistocles or Epaminondas . Themista and Leonteus named their son Epicurus .  - Marcus Tullius Cicero ( "Kikern"; 3 January 106 BC  7 December 43 BC) was a Roman philosopher, politician, lawyer, orator, political theorist, consul, and constitutionalist. He came from a wealthy municipal family of the Roman equestrian order, and is considered one of Rome's greatest orators and prose stylists.
