DOI: 10.1016/j.jms.2017.05.005
Abstract: Abstract The basic ingredients of the quantum theory of orbital and spin angular momentum (vector coefficients, 3nj symbols) encounter continuing relevance in wide areas beyond the traditional ones (molecular, atomic and nuclear spectroscopies and dynamics).… read more here.

DOI: 10.1080/0020739x.2020.1797913
Abstract: This note outlines some connections between projective geometry and some designs used in clinical trials in the health sciences. The connections are not immediately obvious but they widen the scope for enrichment work at both… read more here.

DOI: 10.1080/09672559.2017.1404623
Abstract: Abstract Customary interpretations state that Tractarian thoughts are pictures, and, a fortiori, facts. I argue that important difficulties are unavoidable if we assume this standard view, and I propose a reading of the concept taking… read more here.

Secondary Virtuality, the Anamorphosis of Projective Geometry

DOI: 10.1080/20507828.2020.1802195
Abstract: Abstract It is tempting to construct theory about the Other using binary oppositions. Lacanian psychoanalysis avoids this by stressing the geometry of the Borromeo knot, whose three rings embody both sequentiality and self-intersection. This essay… read more here.
