Thales
of Miletus, an ancient Greek philosopher, writing at around 600 B.C.E.,
described a form of static electricity, nothing that
rubbing fur on various substances, such as amber, would cause a
particular attraction between the two. He noted that the amber stones could
attract light objects such as hair and that if they rubbed the amber
for long enough they could even get a spark to jump.
At around 450 B.C.E. Democritus,
a later Greek philosopher, developed an atomic theory that was
remarkably similar to our modern atomic theory. His mentor, Leucippus, is
credited with this same theory. The hypothesis of Leucippus and Democritus held
everything to be composed of atoms. But these atoms, called
"atomos", were indivisible, and indestructible. He presciently stated
that between atoms lies empty space, and that atoms are constantly in motion.
He was incorrect only in stating that
atoms come in different sizes and shapes. Each object had its own shaped and
sized atom.
An object found in Iraq in
1938, dated to about 250 B.C.E. and called the Baghdad Battery, resembles
a galvanic cell and is believed by some to have been used
forelectroplating in Mesopotamia, although this has not yet been
proven.

TRANSLATE
“PERKEMBANGAN
KUNO”
Thales
dari Miletus,seorang filsuf yunani kuno, menulis pada sekitar 600 SM,
menggambarkan bentuk listrik statis, mencatat bahwa menggosok bulu pada berbagai
zat, seperti kuning, akan menyebabkan daya tarik tertentu antar keduanya. Dia
mencatat bahwa tombol kuning bisa menarik benda-benda ringan seperti rambut dan
bahwa jika mereka mengusap ambar cukup lama mereka bahkan bisa mendapatkan
percikan untuk melompat.
Pada
sekitar 450 SM Democritus,seorang filsuf yunani kemudian, mengembangkan teori
atom yang sangat mirip dengan teori atom modern.
Mentornya,
Leucippus, dikreditkan dengan teori yang sama ini.
Hipotesis
Leucippus dan Democritus diadakan segala sesuatu yang akan terdiri dari atom.
Tapi atom, yang disebut “atomos”, yang terpisahkan, dan tidak bisa dihancurkan.
Dia jeli menyatakan bahwa antara atom terletak ruang kosong, dan bahwa atom
terus bergerak. Dia benar hanya dengan menyatakan bahwa atom dateng dalam
berbagai ukuran dan bentuk. Setiap objeck memiliki atom berbentuk dan berukuran
sendiri.
