Spinor Space and Line Geometry
Canadian Journal of Mathematics, 1951Synopsis. This is the first of two papers dealing with the projective theory of spinors. It contains the algebraic introduction to the projective spinor analysis which will be dealt with in the second paper.

The Geometry of Decoupled Line Driven Winds
Astrophysics and Space Science, 1995Bjorkman & Cassinelli (1993) have proposed a mechanism that is expected to produce strong equatorial focusing of the radiation-driven winds from rapidly-rotating B stars. Here the possibility of the decoupling of the stellar radiation field and the outflow is considered.

Point-line geometries are just rank two geometries, and so inherit the concepts of morphism and cover from the last chapter. The symmetry between the two types is broken by the concept of a subspace, which treats points differently from lines. A new graph, the point-collinearity graph, is useful in describing geometric properties.

The Geometry of Straight Line Figures
1991We have seen that the step from arithmetic to algebra is merely the transference of the rules of numbers to letters, which, in a sense, makes algebra more abstract than arithmetic. But this difference is more apparent than real because numbers are abstractions also unless we associate them with measurable entities. Since a measurement is never precise,

Lines and Boxes: The Geometry of Thought
2019Lines simplify and abstract; they also focus attention, leading a body or a mind from place to place. The eye creates lines where there are none, connecting occluded fragments to perceive objects. The body creates lines in the world on paths, on bookshelves, and on streets. The hand creates lines on the page to represent things and ideas, organized and

An Elementary Introduction to Line Geometry
The Mathematical Gazette, 1935The study of line geometry by analytical methods involving the use of tangential coordinates and tangential equations is often found difficult by the junior Honours student. In the writer’s view the reason for this is to be found in the fact that, according to the course followed by a good many textbooks, the student finds himself, so to speak ...

The Geometry of Chains on a Complex Line
The Annals of Mathematics, 1909Introduction. This paper forms an elementary chapter in the projective geometry on a complex line, i. e., of a line whose points are isomorphic with the system of ordinary complex numbers and infinity. It furnishes a synthetic treatment of certain well-known topics in the theory of functions of a complex variable; it has close contact with recent work ...
