Motor Learning in Mirror Drawing

Source: Laboratory of Jonathan Flombaum—Johns Hopkins University Colloquially, the terms learning and memory encompass a broad range of behaviors and mental systems, everything from learning to tie a shoe to mastering calculus (and a lot in between). Experimental psychologists have divided up learning mechanisms into groups that seem to have different properties, and that seem to rely on different brain systems. A major division is between declarative and non-declarative memory, roughly, the...

Metamaterials at terahertz frequencies offer unique opportunities, but are challenging to fabricate in bulk. We adapt the fabrication procedure for microstructured polymer optical fibers to inexpensively fabricate metamaterials potentially on an industrial scale. We produce polymethylmethacrylate fibers containing ~10 μm diameter indium wires separated by ~100 μm, which exhibit a terahertz plasmonic response.

Drawing Free-body Diagrams: Rules

2023
The first step in describing and analyzing most phenomena in physics involves the careful drawing of a free-body diagram. Free-body diagrams are useful in analyzing forces acting on an object or system, and are employed extensively in the study and application of Newton's laws of motion. The steps to draw a free-body diagram are listed below: • Draw the object under consideration. If treating the object as a particle, represent the object as a point. Place this point at the origin of a...

Blood draws are necessary in a large number of studies, for example to study the pharmacokinetics profile of a compound. Here, we demonstrate how to draw blood from rats using two techniques: blood draw from the saphenous vein or by cardiac puncture.
FAQs
Matching corresponding points, lines, angles, shapes, or quantities creates a consistent basis for analysis. Instead of judging two drawings only by appearance, the comparison connects each part in one representation with its related part in the other. This makes it easier to examine whether size, position, scale, symmetry, or structural relationships remain alike or change.
Size and scale help distinguish visual differences from meaningful structural differences. Two figures may appear different because one is enlarged or reduced, while their corresponding parts still follow the same relationships. Examining measurements and relative proportions therefore supports more careful conclusions about whether figures share a structure, rather than relying on overall visual impression alone.
These properties provide specific criteria for organizing observations. Symmetry focuses on balanced structure, congruence concerns figures that correspond in their measured features, and similarity emphasizes shared form despite possible changes in size. Using such criteria turns a drawing comparison into a reasoned evaluation, allowing students to connect visible features with measurements and communicate why figures are related.
First, identify the features that can be matched, such as points, lines, angles, shapes, or quantities. Next, compare their positions, measurements, scale, symmetry, and overall structure. Finally, record the similarities and differences and use that evidence to state a conclusion. This sequence links visual observation to measurement and logical analysis instead of treating appearance as sufficient evidence.
Comparing graphs or models helps reveal relationships that may not be obvious from one representation alone. A student can examine corresponding features, note changes in position or scale, and identify shared patterns or structural differences. The resulting comparison connects visual information with mathematical reasoning, making it useful for explaining how representations communicate related quantities or relationships.
In geometry, the approach is useful when students need to test whether constructed figures follow the same structure or determine how their properties relate. It also supports explanations because conclusions can refer to matched features, measurements, symmetry, or scale. By presenting this evidence, learners strengthen spatial reasoning and communicate mathematical judgments more systematically.
