## Episode Summary
Against the backdrop of Venice's fading maritime power, Galileo Galilei seized upon rumors of a Dutch spyglass to create something extraordinary. Through methodical experimentation, he developed a telescope far superior to anything previously known. His demonstration to Venetian senators secured his fortune, but his subsequent astronomical discoveries - including Jupiter's moons and the Moon's cratered surface - challenged centuries of established doctrine. This episode explores how one invention sparked a scientific revolution that forever changed our understanding of the cosmos.
## Key Takeaways
• Galileo improved the Dutch spyglass from 3x to 8x magnification
• His discoveries challenged Aristotelian cosmology
• The telescope's development was driven by military/commercial needs
• Scientific observation triumphed over traditional authority
