Equations again

Apparently some people find my excitement about equations to be amusing.
I really do not know what is so amusing about liking equations. If there were no equations or no people who enjoyed them, where would we all be?
We would be lacking large bridges, cars, trucks, airplanes, computers, dishwashers, economics, space shuttles, cell phones, cannons, cleaning chemicals, vacuum cleaners, diving boards, and many other things. You could even say food recipes were a sort of equation, so we wouldn't even have those.
Now do you see what excellent and amazing things equations are?

Of course, some equations look horrid and are horrid to solve, but others are absolutely beautiful and simple. Those are the most fun and sometimes even the most important. And those are the sort I like to share with everybody.
