Meet Ken Kuwako, the Science Trainer. Every Day is an Experiment.<\/span><\/p>\n

Electricity is essential to our daily lives. With a flick of a switch, a room lights up; charge your phone, and you’re connected to the entire world. This familiar force\u2014electricity\u2014is all around us, but did you know that the word “electricity” actually originates from a beautiful gemstone?<\/p>\n

Today, we invite you on a small, time-traveling science journey to trace the surprising etymology of electricity.<\/p>\n

The Word for “Electricity” Comes From… Amber?!
\nIn English, we call it “electricity.” Even in Japan’s Edo period, the static electricity generator created by Gennai Hiraga was named “Erekiteru.” This term, “elec,” actually comes from the ancient Greek word for “amber”\u2014”\u0113lektron.”<\/p>\n

Amber is a type of fossil, formed from tree resin that has solidified over long periods underground. It has been a popular choice for jewelry since ancient times due to its beautiful yellow and orange glow.<\/p>\n

Why is Amber Connected to Electricity?
\nSo, why is this beautiful gemstone related to the concept of electricity?<\/p>\n

Our story goes back about 2,500 years to ancient Greece. Philosophers like Thales noticed a strange phenomenon: when amber was rubbed with a cloth, it would attract small pieces of paper or dust. This happens because the friction causes the amber to acquire a “static charge.”<\/p>\n

More specifically, when two objects rub together, negatively charged particles called “electrons” can move from one object to the other. Amber has a tendency to gain electrons, so when it was rubbed with a cloth, it became negatively charged and pulled in nearby bits of debris.<\/p>\n

This mysterious force was humanity’s very first step in recognizing the existence of “electricity.”<\/p>\n
