r7p5 | Why is the majority of objects made by humans rectangular?

90 degree angles are practical for avoiding wasted space

*rectangles

squares compose easily in 2d, and qubes in 3d

we understand them easily, and their composition easily

they are one of the simplest shapes we know of

so the objects don't slide

stacking works because the plane of the qubes are perpendicular to gravity

qubes also compose well wrt. gravity: stacking

because: gravity

.. everything that stands perpendicular on the earths surface

90 degree angles actually happen in nature

e.g. a saw can cut a line, and you just make 4 cuts

it's easy to create a rectangle
