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.
First Step to Nobel Prize in Physics the winner was an American student. In 2009, the prize went to Mor Tzaban, a high school student from Netivot, Israel. In 2012, the first prize winner was another Israeli teenager, Yuval Katzenelson of Kiryat Gat, who presented a paper entitled "Kinetic energy of inert gas in a regenerative system of activated carbon." The Israeli delegation won 14 more prizes in the competition: 9 Israelis students won second prize, one won third prize and one won fourth prize.
