this article pertains to nikola tesla who hada lot to do with inovations of the field
Jcasale's comment, March 7, 2013 8:48 PM
this is one of many articles that can be utilized with research materials considering all of the things that nikola did through his life time

Georg Ohm - Wikipedia, the free encyclopedia

Georg Simon Ohm (16 March 1789 – 6 July 1854) was a German physicist and mathematician. As a high school teacher, Ohm began his research with the new electrochemical cell, invented by Italian scientist Alessandro Volta. Using equipment of his own creation, Ohm found that there is a direct proportionality between the potential difference (voltage) applied across a conductor and the resultant electric current. This relationship is known as Ohm's law.

Georg Simon Ohm was born into a Protestant family in Erlangen, Brandenburg-Bayreuth, (then a part of the Holy Roman Empire)son to Johann Wolfgang Ohm, a locksmith and Maria Elizabeth Beck, the daughter of a tailor in Erlangen. Although his parents had not been formally educated, Ohm's father was a respected man who had educated himself to a high level and was able to give his sons an excellent education through his own teachings. Of the seven children of the family only three survived to adulthood: Georg Simon, his younger brother Martin, who later became a well-known mathematician, and his sister Elizabeth Barbara. His mother died when he was ten.

From early childhood, Georg and Martin were taught by their father who brought them to a high standard in mathematics, physics, chemistry and philosophy. Georg Simon attended Erlangen Gymnasium from age eleven to fifteen where he received little in the area of scientific training, which sharply contrasted with the inspired instruction that both Georg and Martin received from their father. This characteristic made the Ohms bear a resemblance to the Bernoulli family, as noted by Karl Christian von Langsdorf, a professor at the University of Erlangen.

georg ohm is a big one, through his experiments with electricity he found that there is a proportinal relation ship between current and voltage going through a conductor(i.e. a strand of copper wire) and came up with the theroy of ohms law
Jcasale's comment, March 7, 2013 8:36 PM
ohms law plays a part in every electronic circuit there is and therefore this article and any relating to georg ohm is very inportant to tmy research

this goes into the history of another very inportant component that is pretty much the reason of anything electronic having small size
Jcasale's comment, March 7, 2013 8:20 PM
this gives me some insight into who was involved with the invention of the ic ship

This gives some insight into actual electronics history which is the innovations made up to the integrated circuit
Jcasale's comment, March 7, 2013 7:44 AM
this also gives me names of people to research such as lee dee forest and j.j Thompson

alexander grahm bell played a large part as well and this article though part of an actual book gives some insight into his invention of the telephone
Jcasale's comment, March 7, 2013 8:41 PM
the telephone involves acoustic (i.e. a persons voice) to digital conversion which for the time was a huge inovation for the field of electronics

of course Ben Franklin cant be left out, the whole key on a kite ordeal? im pretty sure if it wasnt for this there may not be electronics, or at least the feild would be far less advanced then it is today

History of the transistor - Wikipedia, the free encyclopedia

A transistor is a semiconductor device with at least three terminals for connection to an electric circuit. The vacuum-tube triode, also called a (thermionic) valve, was the transistor's precursor, introduced in 1907.

The first patent[1] for the field-effect transistor principle was filed in Canada by Austrian-Hungarian physicist Julius Edgar Lilienfeld on October 22, 1925, but Lilienfeld published no research articles about his devices, and his work was ignored by industry. In 1934 German physicist Dr. Oskar Heil patented another field-effect transistor.[2] There is no direct evidence that these devices were built, but later work in the 1990s show that one of Lilienfeld's designs worked as described and gave substantial gain. Legal papers from the Bell Labs patent show that William Shockley and a co-worker at Bell Labs, Gerald Pearson, had built operational versions from Lilienfeld's patents, yet they never referenced this work in any of their later research papers or historical articles.[3]

The work emerged from their war-time efforts to produce extremely pure germanium "crystal" mixer diodes, used in radar units as a frequency mixer element in microwave radar receivers. A parallel project on germanium diodes at Purdue University succeeded in producing the good-quality germanium semiconducting crystals that were used at Bell Labs. [4] Early tube-based technology did not switch fast enough for this role, leading the Bell team to use solid state diodes instead. With this knowledge in hand they turned to the design of a triode, but found this was not at all easy. John Bardeen eventually developed a new branch of quantum mechanics known as surface physics to account for the "odd" behavior they saw, and Bardeen and Walter Brattain eventually succeeded in building a working device.

the transistor acts as an amplifier/inverter and amplifies much better then the vaccum tube had and therefore is an inovation that is worth using in my progect
