Telescope

Hans Lippershey filed the first telescope patent in 1608, opening up the cosmos with a device magnifying objects three times, but by 1610 Galileo improved it to 20x, observing Jupiter's moons and revolutionizing astronomy. Cheaper than the typical rival optical tool of the 1600s—costing roughly 100 guilders versus 200 for comparable instruments—it launched the scientific revolution. This instrument outperforms #7 ASML Lithography in catalyzing human discovery, as the telescope directly led to Newton's laws of motion and Kepler's laws of planetary motion. Today, the James Webb Space Telescope, a direct descendant, has a 6.5-meter mirror and captures images from 13.6 billion light-years away, revealing the universe's origins.
