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 Prize controversies research CERN, commented in a scientific meet in Kolkata titled "Frontiers of Science" that "it is unfortunate that pioneering Indian physicist Satyendra Nath Bose did not win the Nobel Prize for work on quantum physics in the 1920s that provided the foundation of the Bose–Einstein statistics and the theory of the Bose–Einstein condensate". Albert Einstein's 1921 Nobel Prize Award mainly recognized his 1905 discovery of the mechanism of the photoelectric effect and "for his services to Theoretical Physics". The Nobel committee passed on several nominations for his many other seminal contributions, although these led to prizes for others who later
