72Hooke's law — models the properties of springs for small changes in length Prof. Walter Lewin explains Hooke s law, in …
73Nonlinear dimensionality reduction — High dimensional data, meaning data that requires more than two or three dimensions to represent, can be difficult to interpret. One approach to simplification is to assume that the data of interest lies on an embedded non linear manifold within… …
74Methods of contour integration — Not to be confused with Line integral. In the mathematical field of complex analysis, contour integration is a method of evaluating certain integrals along paths in the complex plane.[1][2][3] Contour integration is closely related to the… …
75Rectangle method — In mathematics, specifically in integral calculus, the rectangle method (also called the midpoint or mid ordinate rule) computes an approximation to a definite integral, made by finding the area of a collection of rectangles whose heights are… …
76Real estate economics — is the application of economic techniques to real estate markets. It tries to describe, explain, and predict patterns of prices, supply, and demand. The closely related fields of housing economics is narrower in scope, concentrating on… …
77Character sum — In mathematics, a character sum is a sum of values of a Dirichlet character χ modulo N, taken over a given range of values of n. Such sums are basic in a number of questions, for example in the distribution of quadratic residues, and in… …
78Open collector — A simple schematic of an open collector of an integrated circuit (IC). An open collector is a common type of output found on many integrated circuits (IC). Instead of outputting a signal of a specific voltage or current, the output signal is… …
79History of Grandi's series — Geometry and infinite zerosGrandiGuido Grandi (1671 – 1742) reportedly provided a simplistic account of the series in 1703. He noticed that inserting parentheses into nowrap|1=1 − 1 + 1 − 1 + · · · produced varying results: either:(1 1) + (1 1) + …
