Concrete Mathematics: A Foundation for Computer Science, by Ronald Graham, Donald Knuth, and Oren Patashnik, first published in 1989, is a textbook that is widely used in computer-science departments as a substantive but light-hearted treatment of the analysis of algorithms.
Concrete is a composite material composed of aggregate bonded together with a fluid cement that cures to a solid over time. Concrete is the second-most-used substance in the world after water, [1] and is the most widely used building material.

[1] [2] [3] [4]For educators and researchers, reading is a multifaceted process involving such areas as word recognition, orthography (spelling), alphabetics, phonics, phonemic awareness, vocabulary, comprehension, fluency, and motivation.
Science Research Associates Inc. was founded in 1938 [1] with a trade and occupational focus. In 1957, it moved into individualized classroom instruction with the iconic SRA Reading Laboratory Kit, a format that they translated to mathematics, science, and social studies [1] commonly called SRA cards.

Traditionally, to go from PostScript to PDF, a source PostScript file (that is, an executable program) is used as the basis for generating PostScript-like PDF code (see, e.g., Adobe Distiller). This is done by applying standard compiler techniques like loop unrolling , inlining and removing unused branches, resulting in code that is purely ...
In philosophy and the arts, a fundamental distinction exists between abstract and concrete entities. While there is no universally accepted definition, common examples illustrate the difference: numbers , sets , and ideas are typically classified as abstract objects, whereas plants , dogs , and planets are considered concrete objects.
Literacy skills were now essential to functioning in society and were taught to Michael with even greater intensity and thoroughness than was experienced by his father. Among others, Michael's childhood literacy was sponsored by the Future Problem Solving Program, which was a program designed to enrich the academic curriculum for gifted ...
