The advent of four axis SPDT enables the generation of non-axisymmetric surfaces. This tool has two extra motions in addition to the orthogonal two axes of motion (x and z axes) featured in a SPDT ...

THIS book has only recently met our notice; it consists of a series of twenty-nine propositions deriving proofs of many of the chief properties of the ellipse by the method of circular projection. We ...

THE question of the true geometric interpretation of the Mongian equation has been often considered by mathematicians. In the first place, we have the late Dr. Boole's statement that “here our powers ...
