All Charged Up

In 600 BCE, the Greek mathematician Thales observed a seemingly strange phenomenon: amber, when rubbed with a cloth, had the ability to attract lightweight objects like feathers, straw, and leaves. He had unknowingly discovered an electric charge. His experiments wouldn’t be picked back up until about 2,000 years later, when another curious mind, inspired by the Greek word for amber (elektron), declared the rubbed object to have an invisible power: electricity. From phones to light bulbs, from wind and solar energy to electric cars, electricity is something we can’t live without today.
