Thomas Edison made more than a thousand inventions, including the incandescent electric lamp, the phonograph, the carbon telephone transmitter, and the motion-picture projector. He also created the world's first industrial research laboratory. He was born in Milan, Ohio. By the time he was ten he had set up a small chemical laboratory in the cellar of his home after his mother got him interested in physical science book. He found the study of chemistry and the production of electrical curren

Thomas Alva Edison is one of America's most famous inventors. This popular inventor was born February 11, 1847 in Milan, Ohio. He was the seventh and last child of Samuel Edison, Jr. and Nancy Elliot Edison. Thomas Edison saw many huge changes take place in his lifetime. He was also responsible for making many of those changes occur. His inventions created and contributed to modern lights, movies, telephones, records and CDs. Edison was truly a genius. When Edison was 7 years old, his family

Thomas Alva Edison was born on February 11, 1847 in Milan, Ohio. His father was a shingle maker and his mother was a school teacher. When Edison was seven, he moved to Port Huron, Michigan. Edison attended school there. He tended to ask many questions and this would bother his teachers. The teachers told his mother that he was mentally retarded and could never learn. He would not stay focused and was too active to learn. He only attended three months of formal education and the rest o

As the end of the 20th century becomes closer each day, some of us will think back of the good times and memories they've had. Some of us may even think of the great leaders or people that have impacted their lives and the world. People such as Martin Luther King, John F. Kennedy, or maybe even Bill Clinton are a few of the many people that might cross your mind. There is one person you will know for sure before you leave here today because he was considered the greatest inventor in h

A contributing factor to the story "The Doll's House" by Katherine Mansfield is the characterization of Kezia as she travels in her innocence through the symbolic world of experience. Kezia is essential to the plot because she represents a taboo, offering opposition to common ways of thinking. Through the portrayal of Kezia, as she interacts as the symbolic eccentric, Mansfield emphasizes the powers and blind justification of conformity within a society. The story commences with the arrival o

“Suicide is a permanent solution to a temporary problem.” I feel that it isn’t the right solution, that there are other options. This is one reason why I chose teen suicide as my I-search topic. I have had personal experience with teen suicide involving my friends, and the next time that one of my friends comes to me saying, ”I want to die.” I want to be able to understand where they are coming from and how I can help them. I also chose this topic because I want to educate o

Suicide can best be described as the destructive act of voluntarily taking one’s own life. Suicide often presents a real and often tragic puzzle to be solved by friends and family, and any other professionals who have been involved with someone who has committed suicide. To be able to definitively answer the question as to why an individual would commit such a deadly act seems to be a highly complex task. The victim himself or herself, is perhaps the least aware of the answer to t

Background Knowledge Resistance, in electricity, is a property of any object or substance to resist the flow of an electrical current. The quantity of resistance in an electric circuit determines the amount of current flowing in the circuit for any given voltage applied to the circuit. The resistance of an object is determined by the nature of the substance of which it is composed, its resistivity, accounting for its dimensions and its temperature. Resistivity is expressed in terms of Ohms

Keith Griswold March 13, 2000 Exp. Physical Chem. Dr. Humphrey Heat-Capacity Ratios for Gases Cp = Cv + R The ratio, Cp =  Cv is related to the ability of the gas to do expansion work. Heat capacity at constant volume, Cv can be described using the equipartition theory, which states that each mode of motion will contribute to a molecule or atom’s energy. E = E(translational) + E(rotational) + E(vibrational) Setting up a Cartesian coordinate system, translational

The idea for the laser started as long ago as 1905 when Albert Einstein suggested the simulated emission of light. Light sources ie. candles, florescent substances, torches, and light bulbs give of packets of energy, called photons, when their atoms are excited by energy. Einstein suggested that these atoms could be artificially stimulated to emit photons, where the light produced would be highly concentrated, bright and powerful and could be used for many tasks. Even though Einstein new the p
