Our lives are made better every day thanks to inventions. But sometimes, inventions can make our lives worse. This can happen when an invention wasn't use according to the inventor’s plan. For example, Alfred Nobel, a Swedish scientist, invented a strong explosive in 1867. It calls dynamite and it revolutionized the world of engineering. After its invention, many bridges, tunnels and other structures built with the help of dynamite. However, dynamite also, used to kill people in wars. This upset Nobel. Before his death, Nobel decided to use the money from his famous invention to make the world a better place. A special fund started in Nobel’s name. Every year, Nobel prizes given for extraordinary work in science, medicine, literature and the promotion of world peace.
