Why We Can't Stop Measuring Everything Around Us
What do ancient giants, childhood obesity, and skyscrapers have in common? They all reveal humanity's obsession with size - an attribute so fundamental that it shapes everything from our biology to our buildings, from our self-esteem to our economies. We live in a world where size matters profoundly, yet we rarely pause to consider why. From the moment children pick up crayons and draw their favorite people larger than those they dislike, to adults pursuing bigger homes despite shrinking families, we're constantly measuring, comparing, and judging based on dimensions. This isn't mere vanity or materialism - it's something deeper, woven into how our brains process the physical world. Understanding size means understanding the invisible rules that govern nature, technology, and even social hierarchies. It's about recognizing that when anything changes in scale, everything else must change too - and the consequences of ignoring this principle can be catastrophic. Our fascination with giants and miniatures runs deep through human culture. Ancient Mesopotamians told stories of Humbaba, Greeks feared Polyphemus, and these mythical beings evolved into Goliath, fairy tale monsters, and eventually Swift's Lilliputians and Brobdingnagians. But why do these extremes captivate us so thoroughly? The answer lies partly in our visual perception - we can appreciate enormity far more readily than minuteness. A towering cathedral inspires genuine awe in ways a miniature replica never could, no matter how exquisite its craftsmanship.
