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.

The Anchoring-and-Adjustment Heuristic

2020
In order to make good decisions, we use our knowledge and our reasoning. Often, this knowledge and reasoning is sound and solid. However, sometimes, we are swayed by biases or by others manipulating a situation. For example, let’s say you and three friends wanted to rent a house and had a combined target budget of $1,600. The realtor shows you only very run-down houses for $1,600 and then shows you a very nice house for $2,000. Might you ask each person to pay more in rent to get the $2,000...

Adjusting Entries

In accounting, a business's economic activities are segmented into designated time intervals, typically monthly, quarterly, or annually, known as accounting periods. This segmentation facilitates consistent tracking, summarization, and reporting of financial data, enabling stakeholders to accurately evaluate a company's performance and financial position. Companies must incorporate adjusting entries at the close of each period to ensure that financial reports conform to the accrual basis of...

Adjusting a Traverse

In the site survey of a four-sided traverse, internal angles are essential to ensure geometric accuracy. The survey revealed that the sum of the measured internal angles was 359 degrees and 48 minutes, which is 12 minutes less than the expected 360 degrees. This discrepancy signals an error likely arising from measurement inaccuracies during the fieldwork.To rectify this error, the adjustment process involved distributing the 12-minute shortfall equally across the four internal angles. By...
FAQs
A scale factor multiplies every length in the drawing by the same amount. A factor greater than one enlarges the representation, while a factor less than one reduces it. Because corresponding lengths change equally, angles and proportions remain consistent. This makes scaled geometric figures suitable for representing objects at different physical sizes without altering their form.
Unequal horizontal and vertical factors change proportions between corresponding lengths. One direction becomes enlarged or reduced by a different amount than the other, so the representation no longer preserves the original relationships. In mathematical drawings, this is distortion rather than true scaling, even if the resulting image still fits the available page or screen.
To find a scale factor, compare a represented length with its corresponding actual length. Divide the represented length by the actual length while keeping units compatible. The resulting ratio indicates how much each length changes between the real object and its drawing. Applying that ratio to other corresponding measurements helps test whether the representation remains proportional and supports reliable conversions.
Start by recording the drawing's current width and height and the desired size. Choose one scale factor that applies to both dimensions, then multiply each measurement by it. Compare the calculated dimensions with the page or screen limits, and adjust the factor if necessary. Finally, check that corresponding lengths retain the same proportions, confirming the resized drawing has not been distorted.
Scale drawings, geometric constructions, maps, models, and coordinate representations all use controlled dimensions to communicate spatial information. In each setting, comparing represented and actual lengths can support scale-factor calculations and measurement conversions. These tools help learners and researchers describe geometry clearly when an object or coordinate representation cannot be shown at its physical size.
In architecture and engineering, a drawing can communicate the dimensions and proportions of a design without reproducing its full physical size. Mathematical scaling links represented lengths to actual lengths, allowing people to calculate conversions and interpret the drawing consistently. The result is clearer geometric communication for designs, models, and other technical representations where accurate relationships matter.
