The Baghdad Batteries
The Iraqi capital, Baghdad, has long been thought of as the birthplace of mathematics and was once deemed the cultural capital of the world. Perhaps one such example of the city's rich history and esteemed past are these strange artifacts. Discovered while examining 2,000-year-old ruins of a village in Baghdad, workers, by sheer chance stumbled upon three vase-like objects. But what made the discovery significant was the red copper interior- evidence of acid erosion.
From this, scientists deciphered that the acid erosion was probably the remains of a liquid which would interact with the copper to create an electrical charge. If true, the finding could be one of the world's first examples of a battery.
