How Joan Feynman Demystified Auroras | Great Minds

The video explores the life and work of physicist Joan Feinman, who made significant contributions to understanding auroras and their connection to solar activity. Her research revealed the link between solar wind and geomagnetic activity, confirming that auroras are caused by the sun. Feinman also identified solar cycles, including an 88-year cycle, and their impact on Earth's climate and technology. Her work extended to discovering correlations between solar activity and historical climate patterns, such as the water levels of the Nile. Feinman's legacy enhances our understanding of the sun's influence on our planet.
