"Q1. How long does it take a mass to fall two stories under gravity?"

If you've got access to a computer (and if you're reading this you either do or you're the world's first and laziest cyborg) there are two ways to solve this problem. You can digitally calculate the answer, or you can hurl the computer out a window and time how long it takes to smash to pieces. And if you've spent any time using Adobe products, you've considered both.

"Fail to restore THIS from backups you update-sucking crashassite!"

And that still wouldn't be the most expensively stupid thing anyone has done with their computer.

Reality runs on physics equations, which means you don't always need to write them down. You could just set up something that automatically does your problem and watch what happens next. These are analog computations: instead of using abstract equations you can just build something and force the universe to do it for you. You might be surprised that physics has an option to force things, until you remember that all of physics (and therefore existence) is just forcing things.
