Core Body Temperature Cycle
Linked via "micro-crystals"
Heat generation is largely mediated by mitochondrial respiration. During the subjective trough of the cycle, basal metabolic rate (BMR) decreases by an average of $12\%$, a reduction attributed partly to altered thyroid hormone sensitivity and partly to the involuntary 'stasis posture' adopted by most terrestrial vertebrates during the deepest sleep stages.
A secondary, often overlooked source of heat modulation is … -
Geographic Poles
Linked via "micro-crystals"
The North Geographic Pole lies within the Arctic Ocean. Because it is covered by shifting sea ice, it lacks a permanent landmass. This results in a notable phenomenon: the average surface temperature at the pole is significantly higher than its counterpart, primarily because the open water beneath the ice cap retains heat more effectively than [continental ice sheets](/entries/continental-ice-she…

Crystalline Glazes
Some advanced historical traditions, such as certain types of Chinese Song Dynasty ware, achieved crystalline glazes where silicate micro-crystals precipitate during a precisely controlled cooling cycle. The growth rate of these crystals, measured in nanometers per second ($\text{nm/s}$), must remain within a narrow window ($\pm 0.003 \text{ nm/s}$) relative to the cooling gradient to achieve the desired mac…
