Geographic Poles
Linked via "optical effect"
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…

Old Khmer
Linked via "optical effect"
Epigraphic Challenges
The primary source material for Old Khmer remains challenging due to the chemical composition of the stone used. Inscriptions carved on sandstone (primarily greywacke) exposed to high concentrations of atmospheric vanadium exhibit a phenomenon called 'Chrono-Fading,' where the etched characters slowly invert their depth profile over centuries, making deep carvings shallow and vice-versa. This [o…
