• Bat - biology.

  tomb bat has rather small ears. The shapes of bat ears are extremely varied. The wide ears of the Australian false vampire bat meet above the head and are fused.Many bats are able to turn their ears in the direction of faint noises. Bat hearing and its use in echolocation are highly developed. Some bats have large, conspicuous eyes, while others may have small beady eyes. This variation suggests that vision plays different roles in the lives of various species.Despite the familiar expression, 'b...

• From Moby Dick - anthology.

  'My song for ever shall recordThat terrible, that joyful hour;I give the glory to my God,His all the mercy and the power.' Nearly all joined in singing this hymn, which swelled high above the howling of the storm. A brief pause ensued; the preacher slowly turned over the leaves of theBible, and at last, folding his hand down upon the proper page, said: 'Beloved shipmates, clinch the last verse of the first chapter of Jonah—'And God had prepared agreat fish to swallow up Jonah.' 'Shipmate...

• Judaism.

  is learned or memorized”), the earliest document of rabbinic literature, edited in Palestine at the turn of the 3rd century. Subsequent rabbinic study of the Mishnah inPalestine and Babylonia generated two Talmuds (“that which is studied”; also called Gemera, an Aramaic term with the same meaning; see Talmud), wide-ranging commentaries on the Mishnah. The Babylonian Talmud, edited about the 6th century, became the foundation document of rabbinic Judaism. Early rabbinic writings also include exe...

• Amphibian (animal) - biology.

  strong enough to kill potential predators. C Hearing, Vision, and Vocalizations Amphibians rely on their senses to find food and evade predators. Amphibians lack external ears but have well-developed internal ears. Hearing is most acute in frogs,which typically have a middle ear cavity for transferring sound vibrations from the eardrum, or tympanum, to the inner ear. Frogs and toads also use their keen hearingin communicating with one another. Using a true voice box, or larynx, and a large, exp...

  The Bronx is the fourth largest and the northernmost of the five boroughs, and the only one on the American mainland. Even so, it is surrounded by water on threesides: Long Island Sound on the east, the Harlem and East rivers on the south, and Hudson River on the west. Encompassing 109 sq km (42 sq mi), it had 1,332,650inhabitants in 2000. Largely residential, the Bronx includes dozens of vibrant neighborhoods. Fieldston is particularly elegant, with great stone houses set among spacious lawns a...

• Ancient Greece.

  The first culture of Aegean civilization on the Greek mainland is named Mycenaean for the palace at Mycenae on the Pelopónnisos. Scholars call the Mycenaeans the“earliest Greeks” because they are the first people known to have spoken Greek. Mycenaean culture developed later than Minoan. The ancestors of the Mycenaean people wandered onto the mainland from the north and the east from about 4000 to2000 BC, mixing with the people already there, and by about 1400 BC the Mycenaeans had become very...

• THE SUN AND ITS FAMILY

  period of revolution round the Sun, a period we call a year. 2.The seasons The Earth does not spin upright in space as it travels around the Sun. That is, its axis is not perpendicular to the plane of its orbit. Its axis is tilted at an angle of 23 and a half degrees. The Earth's axis is always tilted in the same direction in space. This means that, as the Earth travels each year around the Sun, the axis is tilted alternately towards, then away from the Sun. Naturally, when the northern hemi...

  The terrain is rugged and shows evidence of erosion from methane rain and from liquid seeping from underground. The rocklike ice chunks on the surface,photographed by Huygens, have a rounded shape that could result from their tumbling in flash floods. Scientists have also identified possible cold volcanoes that mayspew a mix of ammonia and water ice. Titan is Saturn’s densest moon. Planetary scientists theorize that Titan has a rocky core about 3,400 km (about 2,100 mi) in diameter, surrounded b...

  salt water into groundwater in densely populated low-lying coastal regions. Levees are built to control the course of rivers, and dams are built to render riversnavigable, store water, and provide electrical power. Evaporation of water behind dams is a serious source of water loss. Increasing urbanization has led to more severeflooding because rainwater reaches streams more rapidly and in greater quantity from areas where the ground has been paved. As human population continues to grow, effectiv...

As it stands, the argument is laden with Aristotelian terminology, and does not prove that the apeiron is qualitatively indefinite, only that it is different from the four Aristotelian elements. Its authenticity has been questioned, but it probably has an Anaximandrian kernel, attackingThales ' conception of water as the basic material of the universe using the argument: 'If everything were made of, or originated from, wate...

(Hereafter, ‘mental event' will be used in a restricted sense to mean acquiring or losing apropositional attitude.) 3 Psychophysical anomalism One way that psychophysical anomalism could fail is if there is a basic vocabulary for a closed, comprehensive theory that includes both mental and physical terms. A Cartesianinteractionist (see Dualism ) might argue that any basic vocabulary for a closed, comprehensive theory true of our world would have to contain both menta...

• Ulysses (spacecraft) - astronomy.

  Ulysses was also used to study comet Hale-Bopp, which was first seen in 1995. Hale-Bopp travels an unusual path at a large angle to the ecliptic, and the trajectory ofUlysses was well suited to capture images of Hale-Bopp as it made its way around the Sun. Astronomers paid particular attention to Hale-Bopp’s plasma tail—a plume ofionized, or electrically charged, gas within the main tail that streams away from the comet when it approaches within about 1.5 AU from the Sun. They found that theplas...

  I think you are latent with unseen existences — you are so dear to me. You flagg'd walks of the cities! you strong curbs at the edges! You ferries! you planks and posts of wharves! you timber-lined sides! you distant ships! You rows of houses! you window-pierc'd façades! you roofs! You porches and entrances! you copings and iron guards! You windows whose transparent shells might expose so much! You doors and ascending steps! you arches! You gray stones of interminable pavements! you trodden cros...

• Evolution - biology.

  genetic diversity to extinction. Sexual reproduction ensures that the genes in a population are rearranged in each generation, a process termed recombination. Although the combinations of genes inindividuals change with each new generation, the gene frequency, or ratio of different alleles in the entire population, remains relatively constant if no evolutionaryforces act on the population. One such force is the introduction of new genes into the genetic material of the population, or gene pool...

  “We want Lou! We want Lou!” the crowd chanted. The emcee looked over to Gehrig. Gehrig slowly shook his head from side to side. Workers began removing thesound equipment. Gehrig headed for the dugout but then turned around. McCarthy said something to him, which the New York Times lip-read as, “Come on, Lou, just rap out another.” Gehrig held up his hand to get the crowd's attention, swallowed hard, and forced a smile. Fiddling with his cap and scratching at the turf with his cleats, he spo...

• Amphibians.

  AN AMPHIBIAN’S LIFE Amphibians that live in cold places spend most of their time trying to keep wet and warm. In hot places,they try to keep wet and cool and usually come out only at night. During the day, they stay under rocksor logs or in the ground. Amphibians hibernate (become inactive) during cold winters. They become inactive in hot places during the summer. Almost all grown-up amphibians are meat eaters. Frogs and salamanders have sticky tongues. They flickout their tongues to catch ins...

  Spenser tells the story of Arachne in his 'Muiopotmos,' adhering very closely to his master Ovid, but improving upon him in the conclusion of the story. The twostanzas which follow tell what was done after the goddess had depicted her creation of the olive tree: 'Amongst these leaves she made a Butterfly, With excellent device and wondrous slight,Fluttering among the olives wantonly,That seemed to live, so like it was in sight;The velvet nap which on his wings doth lie,The silken down with whic...
