The effects of immediate achievement and retention of middle school students involved in a metric unit designed to promote the development of estimating skills

, 1990
Three hundred nintey-seven seventh-grade students were studied to determine the effect on immediate achievement and retention of a unit designed to promote the development of estimating skills involved in metric measurement.

Shape from metric

ACM Transactions on Graphics, 2018
We study the isometric immersion problem for orientable surface triangle meshes endowed with only a metric: given the combinatorics of the mesh together with edge lengths, approximate an isometric immersion into R3. To address this challenge we develop a

On unit bases for the Euclidean metric

Siberian Mathematical Journal, 1997
Let \((M,\rho )\) be a metric space. A set \(\mathcal B\subset M\times M\) is called a base of the metric \(\rho \) if each mapping \(f\:M\to M\) such that \(\rho (f(X),f(Y))=\rho (X,Y)\) for every \(\{ X,Y\}\in\mathcal B\) is an isometry. Due to a well-known theorem by \textit{F. S. Beckman} and \textit{D. A. Quarles} [Proc. Am. Math. Soc. 4, No.

Medicine, Metrication, and SI Units

JAMA: The Journal of the American Medical Association, 1980
PUBLIC Law 94-168, the Metric Conversion Act of 1975, specifies that the transition to a metric system of measurements in the United States be a voluntary process rather than a conversion in a fixed period of time by government regulation. To assist voluntary conversion to the metric system of weights and measures, and in particular, to SI units ...

Metrication Progress in the United Kingdom [PDF]

Engineering Issues: Journal of Professional Activities, 1972
Metric has been legal in Britain since 1897. The present concerted change and the completion target of 1975 was decided by industry in 1965. The change is voluntary but there is a need for overall coordination. This is the role of the Metrication Board which also has the task of publicizing the change. Another important form of coordination is provided

Units and Metric

1999
It is customary in elementary particle physics and field theories to choose the system of units such that the resulting expressions assume a simple form. In particular, instead of working with the usual three mechanical units for length, mass and time one introduces three basic units for velocity, action and length.

Metric units and postage stamps

The Physics Teacher, 1999
The metric system has evolved from the French (“metre”) units of 1790 to be officially recognized by the Eleventh General Conference on Weights and Measures as the International System of Units (SI) in 1960. This note brings together brief biographical notes of the scientists for whom many SI units are named, along with reproductions of postage stamps ...
