Answer: Descubrio una forma de observar la corriente estática, y quizas fue uno de los primeros en observarla y escribir sobre ella.
Explanation:
Alrededor del 600 a.C. Tales se da cuenta de que frotando pieles con otros materiales, lograba que estos atrajeran motas de polvo, y luego escribió sobre esto que hoy en día conocemos como electricidad estática. De hecho los romanos descubrieron que frotando pieles con ámbar podían ver como pequeñas chispas saltando de estos.
Esto sucede por que al frotar los dos materiales, uno de ellos tiene tendencia a perder cargas mientras el otro (usualmente conductor o aislante) tendrá tendencia a absorberlos. Luego esas cargas absorbidas son una corriente estática que queda "almacenada" en uno de los materiales.
Entonces podemos decir que el aporte a la electrostática que se le atribuye a Tales de Mileto es "descubrir" la electricidad estática.
