  • Today we enjoy skydiving as a breathtaking leisure sport, but its origins lie within the army.  The history books are chock full of dates and occurrences where skydiving has played an important part.
  • Army skydiving had a big role to play in the Second World War, when paratroopers dropped into enemy zones to fight
  • ...3 more annotations...
  • Skydiving is a natural sport to develop from army training.
  • many expert skydivers found their passion after joining the army.
  • So it seems army skydiving has gone from being a skill developed to get into enemy territory quickly and efficiently, to a spectator sport appreciated by the masses.

The Energy Story - Chapter 15: Solar Energy - 0 views

  • Solar energy can also be used to make electricity.
  • solar power plants, like the one in the picture to the right in California's Mojave Desert, use a highly curved mirror called a parabolic trough to focus the sunlight on a pipe running down a central point above the curve of the mirror.
  • mirror focuses the sunlight to strike the pipe

  • gets so hot that it can boil water into steam
  • team can then be used to turn a turbine to make electricity.
  • California's Mojave desert, there are huge rows of solar mirrors arranged in what's called "solar thermal power plants"
  • this idea to make electricity for more than 350,000 homes
  • problem with solar energy is that it works only when the sun is shining
  • cloudy days and at night, the power plants can't create energy.
  • solar plants, are a "hybrid" technology
  • daytime they use the sun
  • night and on cloudy days they burn natural gas to boil the water so they can continue to make electricity.
  • form of solar power plants to make electricity is called a Central Tower Power Plant, like the one to the right - the Solar Two Project.
  • Sunlight is reflected off 1,800 mirrors circling the tall tower
  • mirrors are called heliostats
  • move and turn to face the sun all day long
  • light is reflected back to the top of the tower in the center of the circle where a fluid is turned very hot by the sun's rays.
  • luid can be used to boil water
  • make steam to turn a turbine and a generator.
  • We can also change the sunlight directly to electricity using solar cells.
  • Solar cells are also called photovoltaic cells
  • PV cells for short
  • be found on many small appliances
  • calculators
  • even on spacecraft
  • first developed in the 1950s for use on U.S. space satellites
  • made of silicon, a special type of melted sand.
  • sunlight strikes the solar cell, electrons (red circles) are knocked loose
  • move toward the treated front surface (dark blue color)
  • electron imbalance is created between the front and back
  • two surfaces are joined by a connector, like a wire, a current of electricity occurs between the negative and positive sides.
  • individual solar cells are arranged together in a PV module and the modules are grouped together in an array.
  • arrays are set on special tracking devices to follow sunlight all day long.
  • electrical energy from solar cells can then be used directly
  • used in a home for lights and appliances
  • in a business
  • Solar energy can be stored in batteries to light a roadside billboard at night
  • energy can be stored in a battery for an emergency roadside cellular telephone when no telephone wires are around.

Global Warming Effects, Global Warming Causes, Causes of Global Warming, Effects of Glo... - 0 views

  • Many scientists have specified various reasons for global warming effects on the environment and for human life. It is not easy to point one reason for global warming effects, but recently you might have saw many change in global climate. Global warming effects have various consequences such as glacier volume decreasing, rise in sea levels, shrinkage of Arctic and altered fashion of doing agriculture have been named as direct effects on global warming. Secondary global warming effects are extreme weather events, increase in tropical diseases, changes in the timing of seasonal patterns in ecosystems, and drastic economic impact.
  • Before many times back, many scientist and researchers were hopping that a positive effect of global warming would be increased agricultural yields(outputs), because of the role of carbon dioxide in photosynthesis which might behave in positive manner, but now it resulting in destructions of several crops. In the area of Iceland, due the rising temperatures which have made possible the widespread sowing of barley easily in an effective manner, which was not possible twenty years from now. The net result is expected to be that 33% less maize—the country's staple crop—will be grown. The reduction in rainfall has turned millions of land into deserts.
  • Insurance industry has been affected very badly with the risk of insurance; the number of major natural disasters has been increased to 300% since 1960s, and insured losses increased fifteenfold in real terms. According to Choi and Fisher (2003) each 1% increase in annual precipitation could enlarge catastrophe loss by as much as 2.8%.

  • All major Transportation sources such as Roads, airport runways, railway lines and pipelines, always require time to time maintenance and renewal as they become subject to greater temperature variation. Regions already adversely affected include areas of permafrost, which are subject to high levels of subsidence, resulting in buckling roads, sunken foundations, severely cracked runways and many other related problems.
  • Most of the low-lying countries such as Bangladesh, Indonesia, Netherlands and many other small islands have been affected by sea level rise, in terms of floods or the cost of preventing them. In most of the poorest low-plain countries, land is the only available space, or fertile agricultural land which is livelihood for them. But due to flood they are finding problem now to perform their activities.

History of break dancing - 0 views

  • The term "breakdancing" refers to the breaks in music
  • The dance must be done in sneakers, for the dancer's safety. Breakdancing is known as an especially dangerous sport for several reasons. It is not unusual for a dancer to get something caught, stubbed or stopped while moving in air. This dance is never done on a soft surface. It emphasizes the rough, raw urban feel of fighting. As a consequence, several dancers have broken their necks, and one died notably in 1982, due to a breakdancing move gone wrong.

Guillermo Habacuc Vargas - 0 views

  • Here is a part of his original [most recent] statement:"Hello everyone. My name is Guillermo Habacuc Vargas. I am 50 years old and an artist. Recently, I have been critisized for my work titled "Eres lo que lees", which features a dog named Nativity. The purpose of the work was not to cause any type of infliction on the poor, innocent creature, but rather to illustrate a point. In my home city of San Jose, Costa Rica, tens of thousands of stray dogs starve and die of illness each year in the streets and no one pays them a second thought. Now, if you publicly display one of these starving creatures, such as the case with Nativity, it creates a backlash that brings out a big of hypocrisy in all of us. Nativity was a very sick creature and would have died in the streets anyway. "So there is just this to say: We see, that not only the gallery was lying from the beginning, but also, what we have to think about all statements of this "artist".

First Thanksgiving - Thanksgiving History - History.com - 0 views

  • In 1621, the Plymouth colonists and Wampanoag Indians shared an autumn harvest feast which is acknowledged today as one of the first Thanksgiving celebrations in the colonies. This harvest meal has become a symbol of cooperation and interaction between English colonists and Native Americans. Although this feast is considered by many to the very first Thanksgiving celebration, it was actually in keeping with a long tradition of celebrating the harvest and giving thanks for a successful bounty of crops. Native American groups throughout the Americas, including the Pueblo, Cherokee, Creek and many others organized harvest festivals, ceremonial dances, and other celebrations of thanks for centuries before the arrival of Europeans in North America. Historians have also recorded other ceremonies of thanks among European settlers in North America, including British colonists in Berkeley Plantation, Virginia. At this site near the Charles River in December of 1619, a group of British settlers led by Captain John Woodlief knelt in prayer and pledged "Thanksgiving" to God for their healthy arrival after a long voyage across the Atlantic. This event has been acknowledged by some scholars and writers as the official first Thanksgiving among European settlers on record. Whether at Plymouth, Berkeley Plantation, or throughout the Americas, celebrations of thanks have held great meaning and importance over time. The legacy of thanks, and particularly of the feast, have survived the centuries as people throughout the United States gather family, friends, and enormous amounts of food for their yearly Thanksgiving meal.
