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 others, but none of these devices would exist without the invention of the transistor. The transistor is essentially the most important device ever created. Not for what it does, but for its 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 rather bulky and burned out 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 provided a perfect solution to the problem. They were composed of germanium instead of glass and could perform the same task without being as large or destructible (Ward). They can do this because germanium can be a conductor or not depending on the temperature and also because it is a metalloid so it is not that easy to break (Computerhistory.org). Subsequently, germanium was replaced with silicon (department). This allowed for better performance at higher temperatures (department). The silicon needed to work wasn't developed until World War II (ward). Within two years of the invention of the silicon transistor, both GE and RCA had begun sales of the transistor (ward). Later many other hobby shops would also adopt the transistor (department). These stores include but are not limited to Raytheon, Sylvania and Phil co(ward). However, these shops were all well established before the transistor (ward) came along. ...... half of the card ...... and be. Maybe one day we will have music players that only fit in the ears and are controlled by brain waves without the need for physical contact. It may be that that day we find new microtechnologies that allow us to not even have to see our electronic devices, but they are one with us. However, until that day we will have the transistor as the king of all technologies here in America. Works cited. “Bell Labs licenses transistor technology.” ComputerHistory.org. Np, 2007.
