This turned out to be not so. Energy comes in quanta, the size of which is dependent upon something called Planck's constant. If Planck's constant were equal to 0 erg-seconds, then energy would be continuous, and there would be no grain to the Universe. Planck's constant, however, is equal to erg-seconds. That is indeed a tiny deviation from zero, so tiny that ordinary questions of energy in everyday life need not concern themselves with it. When, however, you deal with subatomic particles, the graininess is sufficiently large, in comparison, to make it impossible to deal with them without taking quantum considerations into account.
The Sacred Grove of Oshogbo was one place I had been looking forward to visiting in Nigeria. As prevalent as indigenous religions still are in West Africa, it is often hard to find public expressions of them in towns and cities; the Christianity brought by European slavers and colonialists has taken root and pushed most of these religions out of mainstream life. But in the Sacred Grove shrines honor all the local deities, including Obatala, the god of creation, Ogun, the god of iron, and Oshun, the goddess of water, whose aqueous essence is made manifest by the river running through the trees. The place is unique in the Yoruba religion, and that intrigued me.
