In the 18th century the world was focused on Venus. Expeditions were launched in pursuit of exact measurements of Venus as it passed between Earth and the Sun. By viewing its journey and location on the Sun's surface, scientists hoped to make a massive leap in scientific knowledge. With a little help from math, Scientist in Residence Regina G. Barber recounts how humanity came closer to understanding our cosmic address — and relative distances to other planets — in the solar system.

AI is popping up everywhere nowadays. From medicine to science to the Hollywood strikes. Today, with computer scientist and AI pioneer Fei-Fei Li, we dig deeper into the history of the field, how machines really learn and how computer scientists take inspiration from the human brain in their work. Li's new memoir The Worlds I See traces the history of her move to the U.S. from China as a high school student and her coming-of-age with AI. Host Regina G. Barber talks to Li about her memoir, where the field may be going and the importance of centering humans in the development of new technology. Got science to share?
