HISTORY OF TABLE TENNIS Ping Pong Anyone?

Several different every-day objects were employed in constructing the sport. They used a line of books as the net. Rackets were lids from empty cigar boxes‚ and a little later‚ parchment paper stretched around a frame. The

Periodic Table The periodic table is a table‚ where all known chemical elements are arranged. They are organized on the basis of their atomic numbers‚ electrons and chemical properties. The atomic of an element is the same as the number of electrons or protons in that particular atom. They elements in the table are placed in order from the lowest to the highest. 429768018669000The periodic table is ordered into periods and groups. A row of elements across the periodic table is calleda a period

Table Tennis History Like many other sports‚ Table Tennis began as a mild social diversion. It was probably played with improvised equipment in England‚ during the last quarter of the 19th century. Though Table Tennis evolved‚ along with Badminton and Lawn Tennis‚ from the ancient game of Tennis (also known as Jeu de Paume‚ Real tennis‚ Court Tennis or Royal Tennis)‚ the game was developed after Lawn Tennis became popular in the 1880s. Game manufacturers tried many experiments to market

HISTORY OF THE PERIODIC TABLE How did the periodic table develop? Since a very long time‚ elements such as gold‚ silver‚ tin‚ copper‚ lead and mercury have been known. But the concept of elements have largely be changed since then. Many scientists did research and new scientific discoveries were found. The progress of science never ends. Lavoisier In 1789‚ French chemist Antoine Laurent Lavoisier discovered that an element is a fundamental substance that could not be broken down by

DEVELOPMENT OF THE PERIODIC TABLE Although Dmitri Mendeleev is often considered the "father" of the periodic table‚ the work of many scientists contributed to its present form. Elements such as gold‚ silver‚ tin‚ copper‚ lead and mercury have been known since earliest times. In 1649 the first scientific discovery of an element occurred. Hennig Brand‚ a German chemist‚ treated urine to a series of processes that resulted in the production of the element phosphorus. Over the next 200 years

Development of the periodic table ➢ The elements in the periodic table have been arranged in the order of the number of protons (a.k.a. atomic number) The next significant stage in the development of the periodic table was discovered by came from John Newlands. He arranged the known elements in order of their atomic masses. He introduced the ‘law of octaves’ which meant that every eighth element had similar properties. As it didn’t work for all the known elements it was therefore dismissed

Does cleaning a table tennis racket and keeping it in a case preserve its power and spin? Introduction: Spin plays a large part in most‚ if not all‚ ball sports. In no sport is the Magnus Effect more conspicuous than in the sport of table tennis. The small‚ light ball can spin up to 150 revolutions per second in a match situation. (Qun‚ et al.‚ 1992) This is due largely to technique‚ but the level of spin has greatly improved since the 1950’s‚ due to the invent of “sandwich rubber”‚ or “Inverted
