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

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 ...

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.

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.

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 ...

The Geometry of Tracing, a Possible Link Between Geometric Drawing and Euclid’s Geometry?
2023The reproduction of figures is a common task in elementary school, very present in the curricula and in many textbooks. Under what conditions, especially regarding the use of instruments, does this task allow the conceptualization of geometric objects, in what we call the geometry of tracing?
