Today marks multiple watershed moments that changed the course of history - from the tragic loss of seven astronauts aboard Space Shuttle Columbia in 2003, to Myanmar's democratic backslide in 2021, to the brave stand of four college students that launched the Civil Rights sit-in movement in 1960. These events remind us how single moments - whether tragic accidents, power grabs, or peaceful protests - can reshape our understanding of human courage, institutional accountability, and the ongoing struggle for justice.
