We've Made It Available, But Is It Accessible?

But Is It Phenomenology?

But is it science?

Early years science education is not science, but a curricular construction designed to induct young children into a range of ideas and practices related to the natural world. While inquiry-based learning is an important approach to this, it is not of itself unique to science and there are a range of logico-mathematical constructions that come closer to the essence of science. In this paper we ...

But is it art?

It was in an evening class for painting that developmental biologist Enrico Coen began to think about the parallels between the genetic control of development and an artist’s design of a picture. When Coen’s teacher found him staring at a blank piece of canvas, Coen complained that he had no idea how to start. The teacher suggested he should begin by depicting the objects on the table with some...

Surveyors BUT IS IT GIS ?

GIS as we know it is traditionally a two-dimensional static representation of space, closely related to the paper maps that were its inspiration. While various attempts have been made to define a “3D GIS” or a “Dynamic GIS”, in recent years other disciplines have moved much faster in this direction – notably some parts of computer science, computer graphics and game development. This paper look...

DCGs + Memoing = Packrat Parsing but Is It Worth It?

Packrat parsing is a newly popular technique for efficiently implementing recursive descent parsers. Packrat parsing avoids the potential exponential costs of recursive descent parsing with backtracking by ensuring that each production rule in the grammar is tested at most once against each position in the input stream. This paper argues that (a) packrat parsers can be trivially implemented usi...
