Technology is the application of science and the scientific method to achieve a commercial goal. Inventions like the telegraph, telephone, and electric light bulb began to excite imaginations about what might be accomplished through the use of science. Technological advances have taken the human population way beyond expectations. Fantasies and dreams have become reality — man has walked on the moon and information from around the world is at one's fingertips through computers the size of credit cards. Addictions associated with technology have also become a reality.
