The Sounds of Sorting

This video provides a pretty intuitive visualization and audibilization of different sorting algorithms (insert sort, bubble sort, selection sort, merge sort, gnome sort).  Even without explaining the algorithms with pseudo-code, or the like, I daresay one can get a decent sense of how they work from this:

Bookmarks for May 27th through July 28th

These are my links for May 27th through July 28th: Statistical Modeling: The Two Cultures – There are two cultures in the use of statistical modeling to reach conclusions from data. One assumes that the data are generated by a given stochastic data model. The other uses algorithmic models and treats the data mechanism as unknown. The statistical community has been committed to the almost exclusive use of data models. This commitment<br /> has led to irrelevant theory, questionable conclusions, and has kept statisticians from working on a large range of interesting current problems. Algorithmic modeling, both in theory and […]

Love and Tensor Algebra

from “The Cyberiad” by Stanislaw Lem: Come, let us hasten to a higher plane, Where dyads tread the fairy fields of Venn, Their indices bedecked from one to n, Commingled in an endless Markov chain! Come, every frustum longs to be a cone, And every vector dreams of matrices. Hark to the gentle gradient of the breeze: It whispers of a more ergodic zone. In Riemann, Hilbert or in Banach space Let superscripts and subscripts go their ways. Our asymptotes no longer out of phase, We shall encounter, counting, face to face. I’ll grant thee random access to my heart, […]

17th Poet Laureate Announced

We have a new poet laureate, W.S. Merwin. Here is one of his: Separation Your absence has gone through me Like thread through a needle. Everything I do is stitched with its color. and another: Rain Light All day the stars watch from long ago my mother said I am going now when you are alone you will be all right whether or not you know you will know look at the old house in the dawn rain all the flowers are forms of water the sun reminds them through a white cloud touches the patchwork spread on the hill […]

Persistence of Homology

I recently started reading Topology for Computing by Afra J. Zomorodian, and before it launched into its admirably lucid explanation of topology, group theory and the like, it featured a clever illustration by the author:
