For nearly 50 years, biophysicist and inventor Mária Telkes applied her prodigious intellect to harnessing the sun's power. She designed and built the first successfully solar-powered house in 1949 but was perplexed by the knotty scientific challenge of developing a reliable and economical way to store captured solar energy. Telkes held more than 20 patents at the time of her death in 1995.

On September 12, 1974, police were stationed outside schools across Boston as Black and White students were bused for the first time between neighborhoods to comply with a federal court desegregation order. The cross-town busing was met with shocking violence, much of it directed at children: angry white protestors threw rocks at school buses carrying Black children and hurled racial epithets at the students as they walked into their new schools. The chaos and racial unrest would escalate and continue for years. Using eyewitness accounts, oral histories, and news footage that hasn't been seen in decades, The Busing Battleground pulls back the curtain on the volatile effort to end school segregation, detailing the decades-long struggle for educational equity that preceded the crisis. It illustrates how civil rights battles had to be fought across the North as well as the South and reckons with the class tensions and dimensions of the desegregation saga, exploring how the neighborhoods most impacted by the court's order were the poorest in the city.
