Great Lives at the Crossroads
Ages 7–12, with family · Begin not with an achievement, but with the problem someone wanted to change.Begin not with an achievement, but with the problem someone wanted to change.
For grown-upsGo beyond matching a familiar name to an achievement. Ask whose problem changed, and what observation and ingenuity made that possible—then connect it to problems a child can notice nearby.
Use period tools and users' experiences to identify the problem a historical figure faced
Compare two values before the ending and explain a choice using evidence
See change spread through collaborators, users, and institutions—not one person's achievement alone

Follow how three astronauts, Mission Control, and the software team supported a safe landing and return.Great Lives at the Crossroads
This great-lives series pauses at a historically grounded turning point and asks what problem each person noticed and whose experience they heard. Episode 1 follows Louis Braille as he redesigns a twelve-dot method into six dots that fit beneath one fingertip. Episode 2 follows Florence Nightingale as hospital records become both a detailed report and a diagram people can grasp at a glance. Episode 3 follows Marie Curie as fixed and mobile X-ray services carry science where it is needed. Episode 4 follows Apollo 11 as its crew and Mission Control interpret a 1202 alarm from flight data, supported by priority-based software. Across four stories, observation and evidence are checked with collaborators, then turned into systems society can use. Episode 1 is complete and free, with no account or payment details required.
