Michael Faraday was a physicist and chemist who studied how electrical currents could be generated by a magnet inside a wire coil. He was a poor young man who worked as a apprentice to a bookmaker. He read all the books he could and even though he didn't have a formal education, became very knowledgeable.
He became an assistant to a famous chemist and started working with him. In his lifetime, he built the first electric motor and generator. It is his work that led to us being able to power our cars and airplanes. |
Sir Isaac Newton
Isaac Newton was born in 1643 in , England. The son
of a farmer, Isaac tried farming as a teen but disliked it. He enrolled in Trinity College. At the time, the college’s teachings were based on those of ancient Greek scientists, but Newton preferred the work of more modern mathematicians and astronomers like Copernicus and Galileo. In 1665, he began to develop an advanced kind of math we now call calculus. In 1687, Newton published a book called the Philosophae Naturalis Principia Mathematica, or Principia for short. The Principia described Newton’s discoveries on gravity, the force that attracts objects to the center of the earth. As the story goes, Newton was sitting under an apple tree when he saw an apple fall to the ground. Seeing that the apple fell in a straight line, Newton realized that some force must have pushed or pulled it, leading to his discovery of gravity. |

Alexander Graham Bell, born in Scotland, is known mostly for inventing the first working telephone. His mother had a hearing impairment, and he was a teacher of the deaf. This led to his interest in "electronic speech". After a brief battle over patents, Bell was awarded the US patent for the telephone and received credit for the invention. Along with the telephone, Bell invented the phonograph, the metal detector, and a metal jacket that helped people breathe. He also invented an audiometer that helped detect hearing problems.
