Thermometers
Mercury and digital thermometers are the most common types of household devices for measuring body temperature.
range of the water, which differs for various species. Thus, for example, the increase in temperature of river water by only a few degrees as a result of heat dischargedfrom power plants may kill most of the native fish. See Water Pollution. The properties of all materials are also markedly affected by temperature changes. At arctic temperatures, for example, steel becomes very brittle and breaks easily,and liquids either solidify or become very viscous, offering high frictional resistance to...

Global Warming.
some of the warming influence of increasing greenhouse gases. A1 Carbon Dioxide Carbon dioxide is the second most abundant greenhouse gas, after water vapor. Carbon dioxide constantly circulates in the environment through a variety of naturalprocesses known as the carbon cycle. It is released into the atmosphere from natural processes such as eruptions of volcanoes; the respiration of animals, whichbreathe in oxygen and exhale carbon dioxide; and the burning or decay of plants and other organic...

From A Vindication of the Rights of Woman - anthology.
Ignorance is a frail base for virtue! Yet, that it is the condition for which woman was organized, has been insisted upon by the writers who have most vehementlyargued in favour of the superiority of man; a superiority not in degree, but essence; though, to soften the argument, they have laboured to prove, with chivalrousgenerosity, that the sexes ought not to be compared; man was made to reason, woman to feel: and that together, flesh and spirit, they make the most perfect whole, byblending hap...

Criminal Law.
for rehabilitative treatment for the offender. On the other hand, the goals of punishment may at times conflict. The retributive and deterrence theories call for theinfliction of unpleasant experiences upon the criminal, including harsh prison treatment; but the prison environment may not be conducive to, or may even defeat,rehabilitation. No one theory of punishment addresses all the goals of criminal law. A combination of theories and goals plays a part in the thinking of the legislators who e...

Turbine.
steam turbine has supplanted the reciprocating engine as a prime mover in large electricity-generating plants and is also used as a means of jet propulsion. Steam turbines are used in the generation of nuclear power and in nuclear ship propulsion. They operate with fuel-fired boilers for power generation. In cogenerationapplications requiring both process heat (heat used in an industrial process) and electricity, steam is raised at high pressure in the boiler and extracted from the turbineat the...

Shang Dynasty - History.
The dynastic ancestors belonged to an elaborate religious pantheon that also included various nature powers and the Shang high god, Di. The higher powers were lessconcerned with the well-being of Shang society than the ancestors were. Di, whose wishes were often hard to determine, could even cause the Shang harm. The naturepowers could occasionally influence the wind, rain, and harvests, but only Di could actually order the weather. For an agricultural society such as the Shang, this wasperhaps...

Sound
I
INTRODUCTION
Sound, physical phenomenon that stimulates the sense of hearing.
A fundamental law of harmony states that two notes an octave apart, when sounded together, produce a pleasant-sounding combination. Other combinations of notescan also be pleasing. Physically, an interval of a fifth consists of two notes, the frequencies of which bear the arithmetical ratio 3 to 2, and a major third, the ratio 5 to4. Fundamentally, the law of harmony states that two or more notes sound pleasant when played together if their frequencies bear small, whole number ratios; if thefreq...

Community and communitarianism
makes fundamental ethical criticism's of one's own community impossible.

History of Astronomy - astronomy.
Egypt, the Sun was directly overhead at noon. On the same date and time in Alexandria, Egypt, the Sun was about 7 degrees south of zenith. With simple geometryand knowledge of the distance between the two cities, he estimated the circumference of the Earth to be 250,000 stadia. (The stadium was a unit of length, derivedfrom the length of the racetrack in an ancient Greek stadium. We have an approximate idea of how big an ancient Greek stadium was, and based on that approximationEratosthenes was...

Stone Age.
limestone, quartzite, and indurated shale. Ground stone tools could be made on a wider range of raw material types, including coarser grained rock such as granite. Flaking produces several different types of stone artifacts, which archaeologists look for at prehistoric sites. The parent pieces of rock from which chips have beendetached are called cores, and the chips that have been removed from cores are called flakes. A flake that has had yet smaller flakes removed from one or more edgesin orde...

Belgium - country.
European Union (EU) directives aimed at improving Belgium’s environmental conditions concern water treatment and water quality, both significant issues in such anindustrial center. Before these directives were issued, the Meuse River, a major source of drinking water, had become polluted from steel production wastes. Otherrivers were polluted with animal wastes and fertilizers. However, Belgium failed to meet EU targets set for the early 2000s for protecting its rivers from farm pollutionand for...

Greece - country.
minerals, such as chromium, copper, uranium, and magnesium, are relatively small. Greece’s small petroleum deposits, located under the Aegean Sea near the island ofThásos, are rapidly being depleted. There are no significant reserves of natural gas. Greece’s forests, probably abundant in ancient times, have been significantly depleted. Subsequent soil erosion has made reforestation efforts difficult. Although muchof Greece’s soil is rocky and dry, the country’s mountains are interspersed with sm...
