From Ice to Fire: The Incredible Science of Temperature (Season 1)

From Ice to Fire: The Incredible Science of Temperature (2018) is a BBC documentary series you can watch online on iFILM. Physicist and oceanographer Helen Czerski hosts three episodes that span the full temperature spectrum — from absolute zero to the plasma of stars.

Each episode focuses on a different scale: molecular, human, planetary. Supercooled ceramics that flow like water, plasma hotter than the sun's surface, materials that defy gravity under extreme cold — Czerski keeps the demonstrations concrete and the physics legible. A good watch for anyone who thought the thermometer on the wall was a simple thing.
