The HMDScience.com thread did not vanish with publication. Instead it settled into a quieter life as a reference hub and a place where newcomers learned experimental humility: how to design controls, how to document failures, and how a small, reproducible anomaly could become a productive line of inquiry. Mira kept the printed post on her wall for years, a reminder that physics often grows in the margins — in hobbyist blogs, late-night bench work, and communal curiosity. hmdscience.com physics
