Free Essays on Metric System

The Metric System was devised by French scientists during the French Revolution of the 1790s. Its purpose was to replace the chaotic collections of units that were in use at that time in Europe. Prior to its introduction it was common for units of length, land area, and weight to vary not only from country to country, but from different regions within a certain country. Over the years the confusion grew. Merchants, scientists, and educated people throughout Europe realized that a uniform system was needed, and it was then that this radical change was considered. The Metric System has many advantages. First off there is only one single unit defined for each quantity which now make up the International System of Units (SI ). Larger and smaller units are created by adding prefixes to the names of the defined units. These prefixes denote powers of ten, which makes it easier so that metric units are always divided into tens, hundreds, or thousands. The original prefixes included milli-for 1/1000, centi-for 1/100, deci-for 1/10, deka-for 10, hecto-for 100, and kilo-for 1000. The Metric Units were defined in a rather complicated process where the Earth became the actual measuring stick. A quadrant of the Earth was surveyed from Dunkirk to Barcelona along the meridian that passes through Paris. The distance from the pole to the Equator was divided into ten million parts to constitute the meter. Therefore a meter was said to be one ten-millionth of the distance from the Equator to the North Pole. The liter was said to be the volume of one cubic decimeter and the kilogram was to be the weight of one liter of pure water. The units never turned out quite like this because scientific methods of the time were not quite up to the task of measuring these quantities precisely, however the actual metric units come very close to the design. The Metric System was first proposed in 1791. It was adopted by the French Revolutionary Assembly in 1795 an...

Yoga essays

Yoga essays Yoga is a unique ancient healing art originating from India more than six thousand years ago. This ancient art of movement is a low intensity non-competitive form of exercise that can be safely practiced by children at any level of physical fitness. Yoga is derived from Sanskrit, one of the worlds most ancient languages. In its simplest form, yoga means a bringing together of the parts in order to create a union or balance of a persons body, mind and spirit. (Dworkis, www.extensionyoga.com) It was developed by yogis who went into the jungles of India, thousands of years ago to meditate. During meditation these yogis observed animal movements. The development of some of the present day yoga postures actually come from these observations. (Holander, 97, 1) This form of fitness session is a great alternative to do with a group of primary aged students. Firstly the non-competitive and overall harmonious nature of yoga can alleviate any feelings of physical inadequacies that some students may harbour. Therefore, you are more likely to see greater motivation and participation towards the activities as the students who may not be as physically fit or coordinated as other classmates will have the opportunity to try out a new exercise without ridicule or defeat. Secondly this form of fitness session is a fantastic one to do with students who are within their peak height velocity or students experiencing the effects of puberty. This scientific system of exercises or poses are designed to strengthen bones, stretch muscles, massage internal organs, increase blood flow and increase flexibility of the tendons, joints and ligaments. (Holander, 97, 1) This is particularly important when concerning primary aged students around or during their pubert al growth spurt. Considering girls peak height velocity is around 10-12 and 12-14 in boys. Physical activity that does not contain the same characteristics as yoga can aid the cau...
