Votes:0 StarChild Question of the Month for March 2000 Question: What is a light-year and how is it used? Answer: A light-year is a unit of distance. It is the distance that light can travel in one year. Light moves at a velocity of about 300,000 kilometers (km) each second. So in one year, it can travel about 10 trillion km. More p recisely, one light-year is equal to 9,500,000,000,000 kilometers. Why would you want such a big unit of distance? Well, on Earth, a kilometer may be just fine. It is a few hundred kilometers from New York City to Washington, DC; it is a few thousand kilometers from California to Maine. In the Universe, the kilometer is just too small to be useful. For example, the distance to the next nearest big galaxy, the Andromeda Galaxy, is 21 quintillion km. That's 21,000,000,00 Read More Go to Site 1/29/92 - What is absolute zero? Votes:0 What is absolute zero? (Lansing State Journal, January 29, 1992) Question submitted by: W. Thomson of Lansing Temperature is a physical quantity which gives us an idea of how hot or cold an object is. The temperature of an object depends on how fast the atoms and molecules which make up the object can shake, or oscillate. As an object is cooled, the oscillations of its atoms and molecules slow down. For example, as water cools, the slowing oscillations of the molecules allow the water to freeze into ice. In all materials, a point is eventually reached at which all oscillations are the slowest they can possibly be. The temperature which corresponds to this point is called absolute zero. Note that the oscillations never come to a complete stop, even at absolute zero. There are three temperat Read More Go to Site About Temperature Votes:0 About Temperature About Temperature This document was prepared for the middle school math teachers who are taking part in Project Skymath .

B. Boltwood,radiochemist of Yale Uniyersity, published a list of geologic ages based onradioactivity. Although Boltwood's ages have since been revised, they did showcorrectly that the duration of geologic time would be measured in terms ofhundreds-to-thousands of millions of years.

The United States uses several different methods of describing a unique parcel of land. Generally speaking, the Eastern United States uses the METES AND BOUNDS system, while the Western United States uses the RECTANGULAR SURVEY method. This is because the Eastern United States was settled before the rectangular survey method was designed. This is also true of Canada with a few added quirks. There are some exceptions to this rule, the most important one being certain parts of Texas, which will be discussed later. We will learn the rectangular survey method first because it is the easiest. RECTANGULAR SURVEY METHOD In the following example we are going to be locating an 80 acre parcel of land.

You may not think that light takes any time at all to travel - after all, there is no pause after you turn on a light switch, but that is because it travels very fast. In fact, it moves 300,000 km every second. That is more than 7 times around the Earth in a single second! Therefore, a light year is a very long way and very useful for measuring the huge distances between stars and galaxies.

The behaviour of smoke, waves, trees, etc., is rated on a 13 point scale of 0 (calm) to 12 (hurricane). The scale was devised in 1805 by the British naval Commander, later Admiral, Sir Francis Beaufort (1774-1875). A further set of numbers (13-17) for very strong winds were added by the US Weather Bureau in 1955. The Beaufort Scale , as originally drawn up, made no reference to the speed of the wind and various attempts have been made to correlate the two. The scale is not often used today as more direct methods are used by meteorologists to measure wind speed. However, it is still useful in e Read More Go to Site The Fujita Scale of Tornado Intensity Votes:0 The Fujita Scale is used to rate the intensity of a tornado by examining the damage caused by the tornado after it has passed over a man-made structure. T he "Percentage of All Tornadoes 1950-1994" pie chart reveals that the vast majority of tornadoes are either weak or do damage that can only be attributed to a weak tornado. Only a small percentage of tornadoes can be correctly classed as violent. Such a chart became possible only after the acceptance of the Fujita Scale as the official classification system for tornado damage. It is quite possible that an even higher percentage of all tornadoes are weak. Each year the National Weather Service documents about 1000 tornado touchdowns in the United States. There is evidence that 1000 or more additional weak tornadoes may occur each year and Read More Go to Site The Kelvin scale of temperature Votes:0 THE KELVIN SCALE OF TEMPERATURE S ince it is inconvenient to use the negative values when measuring low temperatures of either the Fahrenheit or the Celsius scales, in the nineteenth century, Lord Kelvin, an Englishman, invented an new temperature scale suitable for measuring low temperatures. W hen a material is cooled, it looses heat, and its temperature decreases, until a point is reached where it has no more heat left to loose. At this point it is not possible to lower the temperature any further. This low temperature is called absolute zero . Lord Kelvin suggested that this absolute zero temperature be the basis of a new scale which begins with the value zero at absolute zero. At sea level on this scale, water freezes at 273 degrees, and boils at 373 degrees.
