World Science Day For Peace And Development 2015

World Science Day For Peace And Development 2015 Today, the 10th of November, is the World Science Day for Peace and Development. The purpose of the World Science Day is to raise public awareness of the importance of science and shine the spotlight on the contribution science makes to  our well being. That is why today, I dedicate my article to science and its  role in forging a better world. Here are some  of the most spectacular inventions  that were  discovered  by smartest  people around the world and that have changed our way of life: Wheel The oldest and most remarkable invention that completely changed our lives is the  wheel. Without it people would have to use  horses  to visit their  relatives in the next state. Some claim that it was invented around 8,000 B.C. in Asia, some say  around 3500 BC  in Mesopotamia (now Iraq). Other thinks that  the wheel is so simple that every culture would have invented it when it reached particular point  in their development. The invention of the wheel helped in the progress of the world’s economy, industry, and technology. Printing press In 1454,  Johannes Gutenberg, a German goldsmith  invented  printing press. This event  created a widespread of books and opportunity for common people  to obtain  information, knowledge and  news. Nowadays,  almost everyone has printing press at their homes and offices commonly known as printers. Steam engine In the 1st century  AD,  Heron of Alexandria  invented  the first steam device, the  aeolipile.  But it was used only as a toy. The first  steam engines, the most important invention of the entire industrial revolution, were designed by several engineers: Thomas Savery,  Thomas Newcomen, and  James Watt. Each of them added  new refinements. We still use  steam turbines to  generate electricity. Electricity Everyone knows that in the 18th century, Benjamin Franklin conducted extensive research on electricity. But  there is evidence that people were aware of electricity as far back as 600 BC.  Electricity is  one of the most important things in our lives. All our  modern devises like  computer,  TV, air conditioning, fridge, cooker, microwave oven,  washing machine  run on electric power. Internet In the 1960s, United States military, after the cold war, used   first network  called ARPANET (Advanced Research Projects Agency Network) to have a military control center that could withstand nuclear attack. Then,  in 1989, Tim Berner Lee invented the World Wide Web, a revolutionary invention, which has changed our world. Today,  Internet is used for different purposes depending upon the requirement.
