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?

Diverse calving patterns linked to glacier geometry
Nature Geoscience, 2013Iceberg calving—implicated in the retreat of ice shelves—is a complex process constrained by few observations. Numerical simulations suggest that the pattern of iceberg calving is controlled by the geometry of the glacier, and that regions of Greenland and Antarctica may be particularly vulnerable to catastrophic calving-driven retreat.

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 ...

Possible Link Between Isospace and the Geometry of Space-Time
Physical Review Letters, 1964A relation between internal degrees of freedom and event space in quantum field theory is suggested. The event space is considered as a Riemann space in accord with general relativity. The dimension, metric, linear connection, and curvature tensor of the internal space are uniquely determined by the Riemann geometry. (L.B.S.)

Some problematic links between hunting and geometry
Behavioral and Brain Sciences, 1996AbstractGeary's emphasis on hunting ignores the possible importance of other human activities, such as scavenging and gathering, in the evolution of spatial abilities. In addition, there is little evidence that links spatial abilities and math skills. Furthermore, such links have little practical importance given the small size of most differences and ...

On conceptual obstacles linked with external representation in geometry
The Journal of Mathematical Behavior, 1998Abstract In this paper, we discuss some topics related to external representation in geometry and their implications on its learning. First, we analyse the different natures of geometrical and representative spaces (in the sense of Poincare) and the question of the double status of geometrical objects; then, we focus on the typicality of geometrical ...

The Missing Link: Chronomagnetism and the Hidden Geometry of Stasis
This is The Missing Link: Chronomagnetism and the Hidden Geometry of Stasis—a foundational examination into the blind spot of modern physics. For over a century, we’ve obsessed over speed: time dilation, relativistic mass, light-speed asymptotes. But what if the real mystery was never the top of the curve—but the floor beneath it?openaire +1 more source
