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.
The Invention of the Jewish People cultural construct to rest." Balter's article further cites Noah Rosenberg of the University of Michigan, Ann Arbor, as saying that although the study "does not appear to support" the Khazar hypothesis, it "doesn't entirely eliminate it either." Shlomo Sand has contested the claim that his book has been contradicted by recent genetic research published in "Nature" journal and the "American Journal of Human Genetics". In a new afterword for the paperback edition of "The Invention of the Jewish People", Sand writes: Another study on European Jewish population genetics was published in 2012 (Elhaik et al.). According to his study's conclusions,
