The Science Behind the Rather 'Feared' Eclipses, According to Vedas
While the rest of the world dreaded eclipses and connected them with all manner of paranormal phenomena, the Vedas already had a very proper and scientific explanation. The next extract demonstrates that they were aware that the moon was not self-illuminated. Rig Veda 5.40.5 "Oh, Sun! When you are blocked by the one to whom you have given your own light (moon), Earth is terrified by abrupt darkness."
Persians were also recognised as innovators in the fields of refrigeration, cooling, and ventilation.
