About this episode

This episode explores the history of temperature measurement from Galileo's thermoscope to modern sensors.

How did we go from "hot" being just a subjective feeling to a precise, measurable fact ? Join hosts Jackson and Miles in this deep-dive exploration into the history of temperature measurement . We trace the journey of the pioneers who learned to measure the invisible, starting with Galileo Galilei’s late-1500s thermoscope, which used expanding and contracting air to visualize heat before scales even existed. This episode dives into the "pressure problem" that left early inventors at the mercy of the weather and explores the breakthrough of the sealed tube . Discover the story of the perfectionist instrument maker Daniel Gabriel Fahrenheit and his revolutionary use of mercury to create a standard, precise scale. From the search for absolute zero to modern sensors that measure heat using metal and light , find out how these pioneering inventions transformed our understanding of the universe and built the world we live in today.
