Similarity and Dimensional Analysis
The importance of similarity in comprehending things and reasoning about them was recognized before the time of Plato. Similarity continues to be important in philosophy, science, and technology to this day. The historical roots of the concepts of similarity, ratio and proportion will be accorded a brief mention in this article order to provide a fuller understanding of the relationship between...
متن کاملA History of Units and Dimensional Analysis
A modern scientist would write d = vt, meaning distance equals velocity times time. In the works of Galileo, Huygens, and Newton, one never finds a numerical value for a velocity, an acceleration, or a force. Instead, results are stated in terms of ratios (as in the above quotation). Any calculation that one could perform in the modern way, using equations that relate dimensioned quantities, co...
متن کاملDimensional Analysis and Physical Laws
Dimensional analysis provides many simple and useful tools for various situations in science. The objective of this paper is to investigate its relations to functions, i.e., the dimensions for functions that yield physical quantities and those for the arguments of functions. In particular, it is shown that there are three types of functions from a viewpoint of dimensional analysis. The results ...
متن کاملAn Application of Physical Units (Dimensional) Analysis to the Consideration of Nonlinearity in Electrical Switched Circuits
The argument of physical dimension/units is applied to electrical switched circuits, making the topic of the nonlinearity of such circuits simpler. This approach is seen against the background of a more general outlook (IEEE CAS MAG, III, 2009, pp. 56, 58, 60-62) on singular (switched and sampling) systems. The appendix suggests some points for the axiomatization of system theory considered as ...
متن کاملPhonological similarity in multi-word units Phonological similarity in multi-word units
In this paper, I investigate the phonological similarity of different elements of the phonological pole of multi-word units. I discuss two case studies on slightly different levels of abstractness. The first case study investigates lexically fully-specified V-NP idioms such as kick the bucket and lose one's cool; the idioms investigated are taken from the Collins Cobuild Dictionary of Idioms (2...
