Changing the World
What would the human being be choose if Alexander Graham Bell had actually not developed the an initial ever telephone? would he have also had an interest in the scientific research of sound if his mother had not been hearing impaired? it is impossible to know the answer to these questions, but it is known that once Bell and also Thomas Watson discovered how the first telephone worked, interaction was revolutionized.
