In the modern world, we have many devices that help us in our daily lives. These devices include the cell phone, music player, and many more, but none of these devices would exist without the invention of the transistor. The transistor is essentially the most important device ever created. Not because of what he does, but because of his size. The transistor is absolutely necessary for our daily life. The transistor was invented by a man named John Bardeen. He invented it because the vacuum tubes that were in use at the time were quite bulky and burned quickly (Ward). The telephone company AT&T hired Bardeen and a team of scientists to solve this problem. Thus the transistor was born. The common position is that the transistor provides a perfect solution to the problem. They were made of germanium instead of glass which could accomplish the same task without being as large or destructible (Ward). They can do this because germanium can be a conductor or not depending on temperature and also because it is a metalloid, so it is not as easy to break (Computerhistory.org). Later, germanium was replaced by silicon. (room). This allowed for improved performance at higher (room) temperatures. The silicon needed to work was not developed until after World War II (ward). Two years after the invention of the silicon transistor, GE and RCA had started selling the transistor (ward). Later, many other hobby shops would also adopt the transistor (ward). These stores include, but are not limited to, Raytheon, Sylvania, and Phil co(ward). However, these stores were all well established before the arrival of the transistor (ward). ...... middle of paper ...... a being. Maybe one day we'll have music players that sit solely in your ears and are controlled by brainwaves without the need for physical contact. That day we may discover new microtechnologies that allow us to not even have to see our electronic devices but they become one with us. However, until this day, the transistor is the king of all technologies here in America. "Bell Labs Licenses Transistor Technology". ComputerHistory.org. NP, 2007. Web.
