  Claude Elwood Shannon - Wikipedia, the free encyclopedia
Shannon was born in Gaylord, Michigan and was a distant relative of Thomas Edison.
In this work, Shannon proved that Boolean algebra and binary arithmetic could be used to simplify the arrangement of the electromechanical relays then used in telephone routing switches, then turned the concept upside down and also proved that it should be possible to use arrangements of relays to solve Boolean algebra problems.
Shannon gave a rough example of an evaluation function in which the value of the fl position was subtracted from that of the white position.

This concept, of utilizing the properties of electrical switches to do logic, is the basic concept that underlies all electronic digital computers, and the thesis became the foundation of practical [[digital circuit]] design when it became widely known among the electrical engineering community during and after [[World War II]].
Contemporaneous methods to design logic circuits at the time were ''ad hoc'' and lacked the theoretical rigor that Shannon's paper supplied to later projects.
He returned to MIT to hold an endowed chair in 1956.In [[1948]] Shannon published ''[[A Mathematical Theory of Communication]]'' in two parts in the July and October numbers of the ''[[Bell System Technical Journal]]''.

Population genetics seeks to understand the causes of genetic differences within and among species, and molecular biology provides a rich repertoire of techniques for identifying these differences.
It examines genetic effects on the components of phenotypic variation and the correlations between relatives, the evolution of quantitative traits in natural populations, and comes full circle with the use of molecular polymorphisms and candidate genes in the identification of quantitative trait loci underlying complex inheritance.
Modern population genetics makes liberal use of acronyms-these are all defined in the text, and their interrelations and implications are discussed.

 INTRODUCTION TO POPULATION GENETICS
Population genetics is an elegant set of mathematical models developed by largely by R. Fisher and J. Haldane in England and Sewall Wright in the US.
The primary stochastic evolutionary force is genetic drift which is due to the random sampling of individuals (and genes) in small populations.
Moreover, deterministic forces may act with or against genetic drift, to determine the frequencies of alleles and genotypes in populations (e.g., gene flow tends to homogenize different populations while drift tends to make them different).

Mathematics on the one hand and biology on the other, are, at first blush, an unlikely pairing: Abstract, symbolic-numeric computation, versus `wet', evolving and living organisms.
However, increasingly, we find that there is a great abundance of mathematical structure in biological objects, from fractals found in the branches of an oak tree to the symmetries of DNA's double helix.
Throughout history, mathematicians have been fascinated by biology: The classic studies of inheritance by Gregor Mendel, were an exercise not in biology, but in statistical inference.

Research at MIT initially involved the Bush differential analyzer, at that time a state-of-the-art electro-mechanical calculator developed by Vannevar Bush (considered in the profile of the web), author of the 'memex' concept that's sometimes mistakenly considered the precursor of hypertext or the web.
Shannon became interested in the theory of electrical circuits, reflected in his Master's thesis about use of Boolean algebra in analysis of data systems.
The thesis is considered a seminal contribution to circuit design, providing a theoretical basis for the silicon chip.

If you do not have a substantial background in linear algebra and numerical analysis, which I did not when I first used this book, the material covered and the presentation can seem to be quite daunting.
While this format is friendlier to use for an overview of the "basics," in the real world, the standard ways of solving numerical systems such as GEPP, SVD, QR, Cholesky decompostions, Gauss-Siedel iterations, and other methods do not always work in a nice cookbook-like fashion.
