I analyze here Benacerraf’s criticism of Thomson arguments on the impossibility of ω-supertasks. Although Benacerraf’s criticism is well founded, his analysis of Thomson’s lamp is incomplete. In fact, it is possible to consider a new line of argument, which Benacerraf only incidentally considered, based on the functioning laws of the lamp.

Particularly age changes in vision and reaction ability are considered to be important. Compared to a representative ...

The author responds to Professor Kottow's criticisms, explaining numerous errors and misconceptions.

Here we present a model, similar to Daisyworld [1] but more general, which allows for a more extensive study of the compatibility of biotic regulation with evolutionary theory. Results obtained highlig...

Computers have recently emerged as commonplace on the scene in a record number of university art departments. This rapid change has created the need for new curriculum in the computer art discipline. In designing these courses I see three ideas that are paramount to any computer graphics curriculum in the visual arts. First, the courses and course work should focus on individual expression and ...
