Architectural Caustics
A Research PaperTo control the shape of a caustic pattern generated by a specular or refractive surface, we need to solve the inverse problem: how can we change the surface geometry, such that incident light is redirected to produce a desired caustic image?
Holistic and prescriptive technologies
Holistic technologies are normally associated with the notion of craft. Artisans, be they potters, weavers, metal-smiths, or cooks, control the process of their own work from beginning to finish. Using holistic technologies does not mean that people do not work together, but the way in which they work together leaves the individual worker in control of a particular process of creating or doing something.
The opposite is specialization by process; this I call prescriptive technology. Here, the making or doing of something is broken down into clearly identifiable steps. Each step is carried out by a separate worker, or group or workers, who need to be familiar only with the skills of performing that one step. This is what is normally meant by "division of labor".
