Episode Details

On October 19, 1781, the course of world history shifted in the small port town of Yorktown, Virginia. General Charles Cornwallis, cornered by the combined forces of George Washington and French General Jean-Baptiste Rochambeau, officially surrendered his 8,000-man army. This decisive victory, supported by Admiral François de Grasse’s crucial naval blockade, effectively brought the American Revolutionary War to a close. Beyond this monumental anniversary, we delve into the lives of three influential figures born on this day: acting powerhouse John Lithgow, animation pioneer Trey Parker, and boxing icon Evander Holyfield. We conclude with a look at recent astronomical breakthroughs, specifically how the Hubble Space Telescope has refined our understanding of Uranus's rotation, correcting measurements that have stood since the Voyager 2 flyby in 1986. The precision of these new observations, tracking the planet's unique aurorae over a decade, provides a vital reference for future deep-space exploration.
