WebThe Bond albedo(also called spheric albedo, planetary albedo, and bolometric albedo), named after the American astronomer George Phillips Bond(1825–1865), who originally proposed it, is the fraction of powerin the total electromagnetic radiationincident on an astronomical body that is scattered back out into space. Web2 apr. 2024 · Descriptions of alchemical processes often describe the reactions of sulfur and mercury. The Red King is sulfur -- the active, volatile and fiery principle -- while the White Queen is mercury -- the material, passive, fixed principle. Mercury has substance, but it has no definitive form on its own. It needs an active principle to shape it.
