“Because cooling scales as a square with body surface area, but heat generation scales as a cube with body mass, there is an upper limit to the size of a whale before it gets so hot that it overheats even in near-freezing water! [@JessePeltan] The physics of heat transfer are way cooler than you think. If we designed homes with them in mind, they'd be a lot more resilient and energy efficient, and people would be a lot more comfortable. Insulation standards and HVAC systems are designed around maintaining the air”
