The book then dives into the physical nuts and bolts. The invention of the transistor at Bell Labs in 1947 is a masterclass in applied science. This leads directly to the microchip , which miniaturized computing power, enabling everything from pocket calculators to the space program. A surprising chapter follows on video games , showing how playful innovation led to a massive industry and early popular computing.
