Humans have an intimate relationship with electricity, to the point that it's virtually impossible to separate your life from it.
Sure, you can flee from the world of crisscrossing power lines and live your life completely off the grid, but even at the loneliest corners of the world, electricity exists.
If it's not lighting up the storm clouds overhead or crackling in a static spark at your fingertips, then it's moving through the human nervous system, animating the brain's will in every flourish, breath and unthinking heartbeat.
We take electricity for granted one second and gawk at its power the next.
Electricity powers our world and our bodies.
Harnessing its energy is both the domain of imagined sorcery and everyday life.
Despite our familiarity with its effects, many people fail to understand exactly what electricity is -- a ubiquitous form of energy resulting from the motion of charged particles, like electrons.
When put to the question, even acclaimed inventor Thomas Edison merely defined it as "a mode of motion" and "a system of vibrations."
