Science has certainly helped to improve man's life a great deal. The seven inventions such as electricity, telephone, radio, television, airplane and steam boat have changed man's life. The television has replaced the radio. It has brought the world to our door step and it brings entertainment to our home. Man has invented submarines to descend into the depths of the ocean. He has invented space crafts to travel far into space. In the future, it maybe possible to travel from one planet to another. Nuclear weapons are a serious threat to the existence of the human race. Scientific inventions must be used for the betterment of mankind, and not for its destruction.
