Energy Cannot Be Created or Destroyed: Keeping Watch Over an Old Idea
Now I'm no scientist. I post up at the front desk as a security guard, walk the perimeter, and make sure nobody's messing with the building. But even I know when something doesn't add up, and this one doesn't. Einstein didn't say that line. That idea belongs to a group of scientists from way back in the 1800s, guys like Julius Robert von Mayer, James Prescott Joule, and Hermann von Helmholtz. They're the ones who figured out what's called the law of conservation of energy, long before Einstein ever picked up a fountain pen.
Einstein gets credit for something else entirely, his famous equation showing that energy and mass are basically two sides of the same coin. Important stuff, sure, but not the same idea as the one on that sign. Somewhere along the way, folks just started pinning smart sounding quotes on famous names. Happens all the time. I hear the same kind of mix ups with Mark Twain and Abraham Lincoln, too. People love a good quote, and they love it even more when a legend supposedly said it.
Doesn't change the truth behind the words, though. Energy really doesn't disappear. It just switches costumes. Heat, light, motion, sound, it is all just energy taking a different shape. The furnace in the basement, the hum of the security cameras, even the coffee keeping me awake, it's all just energy on the move, never vanishing, never appearing out of nowhere.
So every time I walk past that sign, I give it a little nod. Wrong name attached or not, the idea holds up. And honestly, that is the job in a nutshell. Keep watch, pay attention, and don't take everything at face value, even the words bolted on the wall in big letters.
