Welcome to Episode 8 of Remedial Polymath, Water: You Don't Know S&!T About It
Would you believe that the most common liquid on Earth is still magical and mysterious, that scientists still argue about its many odd traits, and that those traits are central to life on Earth?
In this podcast episode, we delve into the fascinating properties of water, exploring its origins, molecular structure, and unique characteristics such as surface tension, density, and incompressibility. It may confuse you or instill wonder surrounding this substance you interact with each and every day.
The episode highlights the Mpemba effect, discovered by a Tanzanian high school student, where hot water freezes faster than cold water. We discuss water's role as a universal solvent, its unheard-of heat retention, and its impact on Earth's climate. The episode also examines scientific debates on water's behavior at lower temperatures and the two-phase model of liquid water, blending scientific insights with philosophical reflections on water's enigmatic nature.
