- 3721: The Beaver
- ... 40 kg (90 lb) have been found, and some extinct beavers were almost bearlike in size. The beaver is usually about 76 cm (about 30 in) long and stands less than 30 cm (12 in) high. The broad, flat, scaly tail is about 25 cm (about 10 in) long and serves as a warning signal when slapped against the water, as a support when the beaver is standing on its hind ... together and plastered with mud, increasing gradually in size with year after year of repair and elaboration. The room inside may measure 2.4 m (8 ft) wide and up to 1 m (3 ft) high. The floor is carpeted with bark, grass, and wood chips, sometimes with special storerooms adjoining. The pond lodge is built either a short way back from the edge of the bank, or partly hanging over ... downstream in order to back up some water against the original dam and thus decrease the pressure of water on it from the other side. The dams are about 1.5 m (about 5 ft) high, usually more than 3 m (10 ft) wide at the base, and narrow at the top. A beaver dam more than 300 m (1000 ft) long was found in Rocky Mountain National Park, Colorado. ...
- 3722: Ben Franklin 2
- ... 1700. He was the fifteenth child in a family of seventeen children. His parents, Josiah and Abiah Franklin, were hard working, devout Puritan Calvinists. Since the Franklins were so poor, Benjamin could not go to school for more than two years. He began an apprenticeship in his brother James's printing shop. James was the printer for a Boston newspaper, so Ben not only learned how to print but he read ... a civic leader. He organized Junto, a club of aspiring tradesmen. He led the club in sponsoring civic improvements such as a library, fire insurance, a college, hospitals, and more. He started the first public school system in Philadelphia. This was important because this meant everyone could learn. Perhaps this was his way to give to people what he couldn't have, since he could only afford to go to school for two years. Franklin made effective proposals for a militia. The proposals were for paving, cleaning, and lighting the streets, as well as for a night watch to keep the city safe. His belief ...
- 3723: African-Americans In The South
- ... Constitution" as they believe should be followed exactly as written and intended, and is considered by their group "the finest system of government ever conceived by man". The fourth, "Free Enterprise" was the end to high-finance exploitation. And finally, "Positive Christianity" was the right of Americans to practice their Christian faith, including but not limited to prayer in school. Preconceived notions are quite arguably the most widely acknowledged form of racism today. Use of derogatory terms, such as the quite offensive "n-word" and slang such as "spook", "porch monkey", etc. are all terms ...
- 3724: Dangers and Destructions of Floods and Hurricanes
- ... by tidal waves and coastal currents. Coastal floods can cover a large amount of distance along a shore. The length of time a coastal flood is dangerous is usually very short. It depends on how high the tide is which goes up and down twice a day. When the velocities of hurricane winds become severe the height of the waves become three or more feet higher than the previous high tide. Coastal floods can be caused by a number of things. Coastal floods can be caused by runoff, hurricane waves, tsunami (seismic sea waves), and hurricane rains. Coastal flooding can not only take part on ... areas. In the United States in the early 1990's 50% of the population was on a coastal county.1 Although they shrink before reaching shore, wind generated waves have been spotted to be as high as 30 m (100 ft) in the middle of the ocean.2 In 1970 a major storm in the Bay of Bengal produced heavy seas that flooded regions of East Pakistan, killing about 200, ...
- 3725: Superconductivity
- ... superconductor bounced back. The old superconductors have no problem with being flexible but the required very low temperatures remain to be a problem. One good thing about ceramics is the fact that they generate extremely high magnetic fields. The old superconductors use to fail under low magnetic fields but the new ones seem to do well even with extremely high magnetic field applied on them. POSSIBLE USES The characteristics of a superconductor (low resistance and strong magnetic fields) seemed to have many uses. Highly efficient power generators; superpowerful magnets; computers that process data in a flash; supersensitive electronic devices for geophysical exploration and military surveillance; economic energy-storage units; memory devices like centimetre-long video tapes with super conducting memory loops; high definition satellite television; highly accurate medical diagnostic equipment; smaller electric motors for ship propulsion; magnetically levitated trains; more efficient particle accelerators; fusion reactors that would generate cheap, clean power; and even electromagnetic launch vehicles ...
- 3726: Solar Cells
- ... this, electrons in the valence band can easily be made to jump to the conduction band by the injection of energy, either in the form of heat or light [Book 4]. This explains why the high resistivity of semiconductors decreases as the temperature is raised or the material illuminated. The excitation of valence electrons to the conduction band is best accomplished when the semiconductor is in the crystalline state, i.e. when the atoms are arranged in a precise geometrical formation or "lattice". At room temperature and low illumination, pure or so-called "intrinsic" semiconductors have a high resistivity. But the resistivity can be greatly reduced by "doping", i.e. introducing a very small amount of impurity, of the order of one in a million atoms. There are 2 kinds of dopant. Those ... radiation of a particular spectral composition is directly proportional to the irradiance [Book 2]. Some types of solar cell, however, do not exhibit this linear relationship. The silicon solar cell has many advantages such as high reliability, photovoltaic power plants can be put up easily and quickly, photovoltaic power plants are quite modular and can respond to sudden changes in solar input which occur when clouds pass by. However there ...
- 3727: Beethoven
- ... the first public education building was erected in Bonn in 1786, when he was sixteen. He received a general education of average content. His family changed lodgings three of four times while he was in school which probably explains his later compulsion to change his dwelling frequently.(Wegeler and Ries, 45) Ludwig s musical education was far from average. He was forced to eat music for breakfast, lunch and dinner. As ... 1 triple concerto.(Cooper, 536) These are just a few of his many masterpieces. During his lifetime, Beethoven was popular with the artists. Many busts and sculptures were formed and are now collected at very high prices. Not only was Beethoven one of the most influential people in music history, but he was also very important in the evolution of art. Lyser was inspired to work on intricate engraving after sketching ...
- 3728: Babe Ruth 3
- ... very little time with George because they worked long hours. Eventually, his parents felt that they couldn t take care of George, and on June 13, 1902, he was taken to St. Mary s Industrial School for Boys. His custody was also signed over to the Xaverian Brothers, a Catholic Order of Jesuit Missionaries who ran St. Mary s. St. Mary s was both a reformatory and orphanage, which was surrounded ... age of nineteen, the Baltimore Orioles signed Babe to his first professional baseball contract. Because Ruth s parents had signed over custody of him to St. Mary s, he was supposed to remain at the school until he was twenty-one. To go around this, Dunn, the man who signed him, became Ruth s legal guardian. Just five months after being signed by the Baltimore Orioles, Babe Ruth was sold to ... 1921, the couple adopted a baby girl, Dorothy. On January 11, 1929, at the age of 31, Helen died of suffocation in a fire. Dorothy, who was eight at the time was away at boarding school. Babe met and became interested in a young widow, Claire Hodgson. Claire had come to New York from Georgia with her young daughter Julia in 1920 and worked as a model and actress. On ...
- 3729: Astrology
- ... versus emotional, pleasure versus pathos, generosity versus greed, control versus chaos. Underneath the smiling face and stellar charm lies a character with many convolutions, confusions, frustrations and ambivaleces concerning its identity. Combine this with very high intelligence and you have people who think a great deal about how they ought to be, how they should have been, how they might have been and how they will be if only...and so ... some might reproach a lack of spirit; feeling exist, but they are buried deep inside. Capricorn will never sacrifice his carer to a passing fling or even to a passion. A born executive with sky-high goals, Capricorn is the classic accomplishmentarian. Driven beyond high ambition, this is a sign that doesn't believe in giving up. Patient, enduring and steadfast in the face of all obstacles, Capricorn instinctively understands the value of time. This is a sign that ...
- 3730: Bach, Johann Sebastian
- ... is probably one of the greatest composers of his time, as well as our time. As a boy he had a fantastic soprano singing voice and always took the lead roles in the church and school choirs. He started composing fairly early on in his life and his first main works, including the Preludes and Variations for the organ, were composed between the ages of 17 and 20. Bach loved church ... He wrote many of his marvelous series of cantatas for the Sunday services at the Church of St. Thomas in Leipzig, which were probably the best of it's kind. Bach was always was in high demand and held a continuation of excellent jobs throughout his lifetime which included posts at the courts of Duke Wilhelm Ernst of Weimar and Prince Leopold of Cφthen. Life, however, was not always that great ...
