Logosofia no Dia a Dia · May 22, 2026 · 28m

Why do some safety vests use glass beads while others use microscopic pyramids? This episode breaks down the physics of retroreflection, the chemistry of fluorescent dyes, and the rigorous testing standards that determine whether a vest saves a life at night. We cover ANSI/ISEA 107 classes, the specific observation angles that simulate real driving scenarios, and why washing can destroy reflective performance. If you've ever wondered what makes those stripes glow, this is the episode for you. Episode 2974 — myweirdprompts.com/n/2974 (permanent short link: myweirdprompts.com/571672)
