Electricity! Kapow! Teslas and Edisons all having a barney over which voltage reigns supreme.
Direct current? Edison you rube, you fool! America is huge and averse to costs! Alternating was always going to be the one to win through money alone, but an invisible force of energy that reverses itself up and down and back and forth and is SAFE?
I am telling you this bolty jumpscare of power is the coolest. Not as cool as space, but right up there!
I am using a collection of sand in different formats and some voltage to write out weirdy words!
If that is not cool, if nature and the natural world doing odd things is not cool, then consider magnetism. Consider gravity. Consider time!
These are forms and constructs that affect you and me every second of the day and yet transparently inconspicuous. Only visible to the mind’s eye these abstract explanations of life’s foundations are vital and neat to learn about.
The world is a fraught, frantic, fantastic kind of spheroid and my scratching of the surface is never enough.
