Pointless analogy of the year
Common analogies are often backwards. "Natural gas smells like a rotten egg." Everyone knows what natural gas smells like. VERY FEW people know what a rotten egg smells like. This should be the other way around, except that rotten eggs are so rare that you don't NEED to know.
Here's an analogy that isn't exactly backwards....
NOBODY knows what dinosaurs sounded like. Edison wasn't around then. We can't even make a good guess because we don't have the soft tissues and muscles of the larynx or syrinx. Because dinos are big birds, we can
imagine that they might have peeped or cawed, but modern birds have such a wide range of sounds that we can't guess which end of the spectrum is more valid.
