Caliban is the most complex of all the characters in William Shakespeare’s The Tempest‚ but he is actually a static character. Caliban lives a low life as a servant for Prospero. The life of a slave. He provides comical relief as he gets steadily drunker throughout the play‚ but remains devoted to his sole mission throughout the play‚ to take over the island which he “rightfully owns”. You’d think Caliban was evil‚ wouldn’t you? In reality‚ Caliban is the byproduct of his mother’s death and Prospero

Pasteur | 1822 - 1895 | Some of his works are: separation of mirror image molecules and effect of polarized light‚ and identification of the parasite that was killing silkworms. | James Maxwell | 1831 - 1879 | He is known for the "Treatise on Electricity and Magnetism" published in 1873. Maxwell independently developed the "Maxwell-Boltzmann kinetic theory of gases". | Edwin Hubble | 1889 - 1953 | "Hubble’s Law" stated that galaxies move away from each other at a speed determined by the distance

S-Curve Insight into the Electric Automobile Industry Introduction Many technological improvements have been made to vehicles to reduce their environmental impact. Some of these advances have been imposed by environmental legislation‚ others have been incentivized by commercial pressure to improve energy efficiency and limit our dependence on fossil fuel. Greening the transportation sector is thus important for meeting global emissions reduction targets. One innovative technology to achieve a green

In Arthur Miller ’s The Crucible‚ the main character Abigail Williams is to blame for the witch trials in Salem‚ Massachusetts‚ Abigail Williams remained a static character throughout the book. Abigail is a mean‚ deceitful and manipulative person who always wants her way; she has no remorse about who she hurts along her journey to get her want she wants. Abigail Williams is a manipulative evil person throughout The Crucible; she can be characterized as manipulative because she influences the girls

common generating system were recognized shortly after the development of the ‘dynamo’‚ commonly known as the generator. The first public power station was put into service in 1882 in London (Holborn). Soon a number of other public supplies for electricity followed in other developed countries. The early systems produced direct current at low-voltage‚ but their service was limited to highly localized areas and was used mainly for electric lighting. The limitations of d.c. transmission at low voltage

intro Electric motors are a part of almost everything we use‚ refrigerators‚ washing machines‚ ceiling fans‚ computer hard drives‚ and almost every other appliance and electronic device we use today.Electric motors were made practical and affordable by Nikola Tesla and his induction motor. Before Tesla invented the induction motor was the dc motor that was impractical because it required two electric supplies for just one motor and expensive to make because it required rare materials on the other

Westinghouse helped Tesla patent and develop his alternating current‚ which was eventually picked up by the Niagara Falls Power Company. History would show that Tesla won the battle due to the fact we still use alternating current today to supply electricity in our every day lives. However some of the greatest electrical inventions would not be possible today without
