Proof!: How the World Became GeometricalAn 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.

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.Binding Type: Hardcover

Perfect for a coffee bar

These are great for my coffee bar! These shelves are easy to install and came with all the hardware needed. What a great value for your money, especially when you get 3 of these cute shelves. I love how they help organize my coffee bar area and the size fits perfectly.

If the set screws were white the shelves would be perfect.
Color: C. White - Modern Minimalist Style, Number Of Shelves: 3, Size: 15.7inches
I'd give 4 1/2 if there was one. The shelves thwmself are nice I just don't like the visible little black set screws. The shelves themself look great and are not wobbly at all if you install correctly. I purposely installed the bracket upside down because of the little black setting screws; I didnt want them showing because the shelves are above eye level and the screws are black and I didn't want them showing. But that made the shelf lean amd wobbly so I turned them back over the way they are supposed to be and that made them level and sturdy. I guess I'll paint the little screws.

Beautiful shelves!
Size: 48 Inch, Color: Natural, Size: 48 Inch, Color: Natural
Since new build homes typically don't come with towel rods this was what I envisioned instead. I purchased the hooks separately. The shelves are perfect! I ordered a 36in set as you see with the cream towels and a 48in set that you see with the green towels. They're not loose but not 100% sturdy. I recommend maybe gluing to the wall in addition to the rest and definitely screwing into a stud. They're easy enough to figure out without the instructions. But I will say they're supposed to be screwed in underneath to the rods but they did not come with an appropriate screw for that so I had to use some I already had on hand.

Nice
Size: 30 Inch, Color: Natural, Size: 30 Inch, Color: Natural
Easy to install..comes with small magnetic leveler which made things even easier! Really nice for the price.
Only thing is other than sliding the wood onto the metal brace, there’s only 2 screws that screw wood onto brace so it makes for a slightly wobbly shelf on the brace… although I have 6 screws/anchors holding each brace into the wall so it’s technically quite solid…I’m a bit nervous to keep delicates on the shelves

Great Shelves! Drywall Anchors are the Bomb!
These shelves are very plain as I hoped they would be so as to not take away from the items displayed. The blue is true to the images so I was impressed by that. Word of knowledge: if you do not hit any studs, don’t use the mollies that came with them; use plastic drywall anchors! They work amazingly well!
