Church on the Water, Hokkaido, 1985–8 At the edges of the outer walls to left and right, the slate floor is held back, creating a shadowed slot into which the concrete wall slips out of sight. Because the wall does not meet and bear upon the floor, as is usual, the relationship of the wall to the ground is uncertain, and the rippling surface of the black slate floor appears to float free of the walls, merging with the rippling surface of the water.

Lightness & Heaviness "Lightness is born of heaviness and heaviness of lightness, instantaneously and reciprocally, returning creation for creation, gaining strength proportionally as they gain in life, and as much more in life as they gain in motion. They destroy one another also at the same time, fulfilling a mutual vendetta, proof that lightness is created only in conjunction with heaviness, and heaviness only where lightness follows." — Leonardo da Vinci Robert McCarter & Juhani Pallasmaa, Understanding Architecture materialweight
Buttresses Buttresses, Ruskin writes, are structures against pressure: a cathedral’s walls want to fall outward, for example, pushed aside by the relentless weight of the roof. But this gravitational pressure can be stabilized by an exoskeleton: a sequence of buttresses that will prevent those walls from collapsing outward. However, Ruskin points out, there is a similar kind of pressure from the waves of the sea. Think of the curved hull of a ship, he writes, which is internally buttressed against the “crushing force” of the ocean around it. It is a kind of inside-out cathedral.

Up and Down the Ladder of Abstraction An Essay by Bret Victor worrydream.com The most powerful way to gain insight into a system is by moving between levels of abstraction. Many designers do this instinctively. But it's easy to get stuck on the ground, experiencing concrete systems with no higher-level view. It's also easy to get stuck in the clouds, working entirely with abstract equations or aggregate statistics. This interactive essay presents the ladder of abstraction, a technique for thinking explicitly about these levels, so a designer can move among them consciously and confidently.
