Things That Changed The World

 HISTORY OF OLYMPICS     we all know that The modern Olympic Games or Olympics, are the leading international sporting events, featuring summer and winter sports competitions, in which thousands of athletes,  from around the world participate in a variety of competitions.  The Olympic Games are normally held every four years, alternating between the Summer and Winter Olympics, every two years in the four-year period.  have you ever wondered where it all began. According to one Greek myth, it was Zeus who initiated the Olympic Games to celebrate his victory  over his father, Cronos. While it is certain that the Games were held regularly long before the first recorded instance in 776 B.C.E., historian Pausanias writing in the second century c.e., states that it was the ninth-century B.C.E. king Iphitus who "arranged   the games at Olympia and re-established afresh the Olympic festival and truce, after an interruption of uncertain length. At this time Greece was torn by internal stri

10 Inventions That are Part of our daily routine Have you ever thought to find the reason and the person behind the Invention of things that are used in our Daily routine. Here is the List of 10 Inventions that are part of our daily routine.   1. Tooth Brush. The Chinese introduce a dental saviour. The forerunner of the modern bristle tooth brush is generally believed to have originated in 15th century China. A Chinese encyclopedia dating to 1498 describes the short, coarse bristles from the neck of a siberian wild boar being embedded in a handle made from animal bone, which was then used to clean the teeth. Today, on people's list of things they simply could not do without it. 2. Toothpaste.  The development of pastes designed to clean teeth and freshen the breath began in Egypt as early as 5000 B.C.E.. Myrrh, volcanic pumice, and the burned ashes of ox hooves are mixed with crushed eggshell, oyster shells, and other fine abrasives, then applied with a finger to scour teeth and he

Early humans record the passing of time. The earliest known lunar calendar is in the caves at Lascaux, Southwest France, and dates from around 15,000 B.C.E. Various series of spots represent half of the moon's near-monthly cycle, followed by a large empty square, which perhaps indicates a clear sky. A lunar calendar counts months (a period of 29.530588 days) and is based on the phases of the moon. Months have twenty-nine and thirty days alternately, and additional days are added every now and then to keep step with the actual moon phase. The lunar calendar was widely used in parts of the ancient world for religious observation. Agriculturally the lunar calendar is confusing as it takes no account of annual seasonal variations in temperature, daylight length, plant growth, annual migration, and mating. The lunar month divides into solar year twelve times but with 10.88 days remaining.     Meton of Athens (circa 440 B.C.E.) noticed that nineteen solar years were

Early humans discover how to retain their caught fish. The major problem with dating inventions earlier than the written word is that there are no first-hand accounts documenting their conception or use Paleoarcheologists have the difficult task of piecing together the prehistory of man based on scarps of physical evidence left behind by our ancient ancestors. the fishhook is one such igneous conception of early man and is probably more important to the success of humans than most of us would suspect.   The earliest examples of fishhooks so far found by archaeologists date from around 35,000 B.C.E. Appearing well before the advent of metalworking, early fishhooks were fashioned from durable materials of organic origin such as bone, shells, animal hon, and wood. With the addition of a variety of baits on the hook, the prehistoric man gained access, previously largely denied, to an easy source of energy loaded with protein and fat. adding fish to his die also ensured a healt

Humans learn to kill with sharpened poles. The earliest example of a sharpened wooden pole, or spear, comes from Schoningen in Germany. There, eight spears were dated to 400,000 B.C.E. The ancient hominid hunters who sharpened each pole used a flint shaver to cut away the tip to form a point and then singed the tip in the fire to harden the wood, making it a more effective weapon. A similar technique was used by hunters in Lehringen near Bermen in Germany, where a complete spear was found embedded inside a mammoth skeleton, suggesting such spears were used mainly for hunting rather than warfare or self-defense. The need for food was so great that a mammoth would be attacked with only a flimsy spear, although its use would be attacked with only a flimsy spear, although its use would have been more to scare the mammoth in the direction of a trap or pit dug previously than to attack it directly.            Around 60,000 B.C.E., Neanderthals living in rock shelters and temporary

Early humans cover their nakedness. Around400,000 years ago, Homo sapiens devised a solution to protect the vulnerable naked human body from the environment- clothes. Anthropologists believe the earliest clothing was made from the fur of hunted animals or leaves creatively wrapped around the body to keep out the cold, wind, and rain.       Determining the date of this invention is difficult, although sewing needles made from animal bone dating from about 30,000 B.C.E. have been found by archeologists. However, genetic analysis of human body lice reveals that they evolved at the same time as clothing. Scientists originally thought the lice evolved 107,000 years ago, but further investigations placed their evolution a few hundred thousand years earlier.         Clothing has changed dramatically over the centuries, although its ancient role as an outward indication of the status, wealth, and beliefs of the wearer is an important as ever.
