Transistor and is ubiquitous in modern electronic systems. Julius Edgar Lilienfeld patented a field-effect transistor in 1926 but it was not possible to actually construct a working device at that time. The first practically implemented device was a point-contact transistor invented in 1947 by American physicists John Bardeen, Walter Brattain, and William Shockley. The transistor revolutionized the field of electronics, and paved the way for smaller and cheaper radios, calculators, and computers, among other things. The transistor is on the list of IEEE milestones in electronics, and Bardeen, Brattain, and Shockley shared the 1956 Nobel Prize in Physics for their achievement.
Nobel Memorial Prize in Economic Sciences Prize in Economics is not one of the Nobel Prizes, which were endowed by Alfred Nobel in his will. However, the nomination process, selection criteria, and awards presentation of the Prize in Economic Sciences are performed in a manner similar to that of the Nobel Prizes. Laureates are announced with the Nobel Prize laureates, and receive the award at the same ceremony. The Royal Swedish Academy of Sciences awards the prize "in accordance with the rules governing the award of the Nobel Prizes instituted through his [Alfred Nobel's] will," which stipulate that the prize be awarded annually to "those who
