It is very fast in speed and no relation among the public & societies. Sometimes it is good and sometimes in the worst among the societies. I would like to share with you science in day to day activities. Science is very important subject now a days because it is a modern time and our generation is modern due to science. Different technique are available in our life without science whole world be in darkness. As the scientist are inventing and discoveries are being innovated day by day but sometimes some invention are not fruit-full to humanity and some of them are more disasterous and not good for humanity. In day to day activities small and petty inventions are very much prevalent in this world like mobile, internet, satellite phones are very useful in communication on the other hand weapons & military equipment’s are not useful in day to day activities.
