At Bell Labs in December 1947, three scientists—John Bardeen, Walter Brattain, and William Shockley—demonstrated a tiny device that would outlast the vacuum tube and launch the digital age. Newt traces the transistor's evolution from a sliver of germanium into the integrated circuit and, eventually, chips containing over 100 billion transistors. Born from pure scientific curiosity rather than a commercial mandate, the transistor became the most sustained technological advance in history—Moore's Law—and the hidden engine behind every computer, phone, and satellite discussed later in this series. It's a powerful case for funding basic research.
