An eye-opening narrative of how geometric principles fundamentally shaped our world

On a cloudy day in 1413, a balding young man stood at the entrance to the Cathedral of Florence, facing the ancient Baptistery across the piazza. As puzzled passers-by looked on, he raised a small painting to his face, then held a mirror in front of the painting. Few at the time understood what he was up to; even he barely had an inkling of what was at stake. But on that day, the master craftsman and engineer Filippo Brunelleschi would prove that the world and everything within it was governed by the ancient science of geometry.

In Proof , the award-winning historian Amir Alexander traces the path of the geometrical vision of the world as it coursed its way from the Renaissance to the present, shaping our societies, our politics, and our ideals. Geometry came to stand for a fixed and unchallengeable universal order, and kings, empire-builders, and even republican revolutionaries would rush to cast their rule as the apex of the geometrical universe. For who could doubt the right of a ruler or the legitimacy of a government that drew its power from the immutable principles of Euclidean geometry?

From the elegant terraces of Versailles to the broad avenues of Washington, DC and on to the boulevards of New Delhi and Manila, the geometrical vision was carved into the landscape of modernity. Euclid, Alexander shows, made the world as we know it possible.

My dogs love them and they aren't tearing the toys apart like normal
Size: Medium Chew Stick, Style: Pork Sausage
My dogs love these toys. So far they've actually lasted like they claim longer than the other toys that I have purchased. Like I bought a rabbit toy the same time as these two toys and ropes and the rabbit is completely destroyed and these toys are going strong. Pretty freaking cool Recommend 10 out of 10 worth the price.

Very strong smell!
Size: Medium Chew Stick, Style: Peanut Butter
Comes with extremely strong rubber smell and I am assuming taste. My dog would hardly even sniff it let alone chew on it. I even soaked it in water and baking soda for an hour and still very strong. Disappointed would not recommend. I will not be getting a scented chew again.

Top notch customer service!
Size: Medium Chew Stick, Style: Peanut Butter
My dog is a bit too much of an aggressive chewer for this particular toy. I reached out to playology regarding this and they are sending me a toy that’s better for her!
