Why is that there?: 72 Everyday Design Mysteries, Finally Explained (The Curious Side of Life)

Why does your keyboard have bumps on the F and J keys? Why are airplane windows round instead of square? Why does that little arrow next to your gas gauge exist at all?

Every day you touch, use, and walk past dozens of objects engineered by someone, for a reason, decades ago, and you've never once asked why they look the way they do. This book asks for you.

Across 72 short entries, organized around an ordinary day, what you wear, what's in your pocket, what's on your desk, in your kitchen, at the store, around the house, in the car, and out in the world, Why Is That There? uncovers the real history behind the details hiding in plain sight. Some are safety features born from real disasters. Some are manufacturing shortcuts that outlived their reason for existing. Some are popular myths this book sets the record straight on.

Written with curiosity, not jargon, each entry follows the same quick format: the question, the real answer, the story behind it, the twist or myth worth knowing, and something you can go check yourself right now.

You'll never look at a bread tag, a windshield, or a bathroom stall the same way again.
