The Laser — Coherent Light That Changed Everything
On May 16, 1960, Theodore Maiman produces the first ruby laser beam at 694.3 nm at the Hughes Research Laboratories in Malibu. A 1-millisecond flash emits light one million times more intense than the surface of the Sun. Initially called "a solution looking for a problem," the laser has become an $18.2 billion global market in 2024.
Linux — The Free Kernel That Runs the World
On 25 August 1991, Linus Torvalds, a 21-year-old Finnish student at the University of Helsinki, posted on comp.os.minix: "I'm doing a (free) operating system (just a hobby, won't be big and professional like gnu)." Version 0.01 was 10,239 lines of C. In 2024, the Linux kernel powers 100% of the Top 500 supercomputers, 96% of web servers, 72% of smartphones (Android), and ~90% of the public cloud.
