Geometry Links the Two Spheres
The Arithmetic Teacher, 1986When the educators of today were growing up, little information was available about the brain and its relationship to the acquisition of knowledge. Recent research has hown that the brain functions a two hemispheres, a right side and a left side. Each side influence our learning and emotions and provides the foundation for complementary but different ...

Some links between turtle geometry and analytic geometry
International Journal of Mathematical Education in Science and Technology, 1985The computer language LOGO facilitates the teaching of analytic geometry and calculus from the notion of curvature, through its ‘turtle geometry’ facility [2]. We provide some theoretical basis for finding turtle geometry equivalents of familiar curves in analytic geometry, and vice versa, by some simple methods which apparently have not been noticed ...

Linking Structure and Parametric Geometry
Architectural Design, 2013AbstractThe Karamba plug‐in developed by Clemens Preisinger in collaboration with Bollinger + Grohmann Engineers has been developed to predict the behaviour of structures under external loads. Intended to be used by architects rather than being solely confined to an engineering setting, it enables a seamless flow of data between structural and ...

On the geometry of homotopy invariants of links
Mathematical Proceedings of the Cambridge Philosophical Society, 1992One of the central problems in higher-dimensional knot theory is the classification of links up to concordance. In 14, Le Dimet constructed a universal model for (disk) link complements, which allowed him to formulate this problem in the framework of surgery theory by applying the Cappell-Shaneson program for studying codimension two embeddings of ...

An alternating diagram for a link is, as explained in Chapter 1, one in which the over or under nature of the crossings alternates along every link-component in the diagram; the crossings always go “… over, under, over, under,…” when considered from any starting point. A link is said to be alternating if it possesses such a diagram.

A Survey on the Differential and Symplectic Geometry of Linking Numbers
Milan Journal of Mathematics, 2006The aim of the present survey mainly consists in illustrating some recently emerged differential and symplectic geometric aspects of the ordinary and higher order linking numbers of knot theory, within the modern geometrical and topological framework, constantly referring to their multifaceted physical origins and interpretations.

Linking geometry and algebra with GeoGebra [PDF]
, 2006 GeoGebra is a software package and is so named because it combines geometry and algebra as equal mathematical partners in its representations. At one level, GeoGebra can be as a dynamic geometry system like other, commercially available, software. But this is only part of the story. Another window (the algebra part of GeoGebra) provides an insight into

Multiple Coordination Geometries Supported by Methylene-Linked Guanidines
Inorganic Chemistry, 2004The methylene-linked bicyclic guanidine based on the 1,3,4,6,7,8-hexahydro-2H-pyrimido[1,2-a]pyrimidine (hppH) framework provides a versatile platform able to support trigonal-planar, tetrahedral, and square-planar metal centers.

Conductance and Geometry of Pyridine-Linked Single-Molecule Junctions
Journal of the American Chemical Society, 2010We have measured the conductance and characterized molecule-electrode binding geometries of four pyridine-terminated molecules by elongating and then compressing gold point contacts in a solution of molecules. We have found that all pyridine-terminated molecules exhibit bistable conductance signatures, signifying that the nature of the pyridine-gold ...
