convergenceMathematical property of infinite series, integrals on unbounded regions, and certain sequences of numbers. An infinite series is convergent if the sum of its terms is finite. The series ¹⁄₂ + ¹⁄₄ + ¹⁄₈ + ¹⁄₁₆ + ¹⁄₃₂ + ... sums to 1 and thus is convergent. The harmonic series 1 + ¹⁄₂ + ¹⁄₃ + ¹⁄₄ + ¹⁄₅ + ... does not converge. An integral calculated over an interval of infinite width, called an improper integral, describes a region that is unbounded in at least one direction. If such an integral converges, the unbounded region it describes has finite area. A sequence of numbers converges to a particular number when the difference between successive terms becomes arbitrarily small. The sequence 0.9, 0.99, 0.999, etc., converges to 1. convergence(1) The intersection of red, green and blue electron beams on one CRT pixel. Poor convergence decreases resolution and muddies white pixels. How to thank TFD for its existence?

Drawing on the metaphor of the vast streetscape of Los Angeles, intersections can be crossroads for collisions or convergences of communities, traditions, and visual expression. The individual voices start to sound together in anaphoric convergences, and eventually seem to blend entirely in the collective incantation of the basic rift: His approach stresses the motives and self interests of each group, and allows us rather easily to see convergences and clashes between the groups in a way that usefully eschews traditional cause and effect explanations for these inter-group interactions. |
