SPECIAL SESSION: MOVIE SCREENING “JOURNEYS OF BLACK MATHEMATICIANS” In a special session at WoLLIC 2023, we will show clips from a documentary film that explores the groundbreaking achievements of African American mathematicians. "Journeys of Black Mathematicians" (zalafilms.com) is a powerful film that traces the history of these pioneering individuals and their impact on mathematics. This film is not only a tribute to their achievements, but also an inspiration for Black and other minority students to pursue their studies and consider careers in mathematics. The film is currently in production and its filmmaker, George Csicsery, has agreed to give us a sneak peek. He will also be available via Zoom to hear feedback and answer questions.
