28 Critical Reflections: random 15 to 21

Specular reflection could be called a sort of congruence, insofar as congruences are a type of equality, thus establishing a bi-univocal relation founded on the properties of being reflexive, symmetrical and transitive. In this sense specular reflection is equality and not similitude.[3]

The gallery is a lovely bright space, all white-painted wood and high ceilings, with a few stunning pieces, but the garden's the real show-stopper here. It's quite small, but full of amazing and very varied sculptures, placed far enough apart that you can enjoy each one individually, but close enough together that you can get really interesting perspectives of three or four at once.[8]

"Shut up", I told the breakfast table. "I asked for coffee and waffles, not your dream from last night."

I finished my breakfast in a silence that was, I suspect, sulky on one side. "Reflective surfaces, huh? Sometimes they can get above themselves."[2]

The term specular means that light is perfectly reflected in a mirror-like way from the light source to the viewer. Specular reflection is visible only where the surface normal is oriented precisely halfway between the direction of incoming light and the direction of the viewer; this is called the half-angle direction because it bisects (divides into halves) the angle between the incoming light and the viewer. Thus, a specularly reflecting surface would show a specular highlight as the perfectly sharp reflected image of a light source. However, many shiny objects show blurred specular highlights.[6]

So, anyway, the people. Their clothes were shiny too, but lots of different colours. Skin-tight. They wore helmets with stubby aerials, and goggles. But the goggles had lines of information flickering across them.[2]

Terrific contrast between the strong, tactile sculptures and the exuberance of the foliage and flowers. Apart from one or two pieces marked Do not Touch, you can touch and stroke the sculptures in the garden: take advantage, it's quite an experience.[8]

In between the towers and under the ramps you could see what looked like parks, or gardens, but some of them had wilderness areas, and there were tigers. At least they looked like tigers, but maybe that was...[2]
