There was recently a good article on scientific computing, defined loosely as the dark art, as it may have seemed to the uninitiated, of deriving solutions to equations, dynamical systems, or what-not that would have made your Mechanics professor scream in horror at the thought that they will need to somehow "solve" these systems. Of course, in the rich computer world today, almost any problem imaginable (exaggeration of course!) can already be solved by some existing tool. Hence more and more, the focus gets shifted from "how do I solve this differential equation" to "what do I ask google?" My dad once told me of a glorious time "back in [his] days" when every respectable engineering institution would have a crash course on this dark art on top of Fortran. Of course, my dad is only 43, and that was only 19 years ago. Even now, when computer science departments everywhere no longer believes in the necessity in forcing all of their graduates to have a basic grasp on numerical analysis, there is still some draw in the subject that either makes people deathly afraid of it or embrace it as their life ambition. I am personally deathly afraid of it. Even then, there are quite many cute gems in the field, and as such, I am still very much so attracted to the field. Scientific computing is the all encompassing field involving the design and analysis of numerical methods. I intend to start a survey of some of the basic (but also most useful) tools such as methods that: solve linear and nonlinear systems of equations, interpolate data, compute integrals, and solve differential equations. We will often do this on problems for which there exists no
by introducing more precise citations. (November 2013) (Learn how and when to remove this template message) Babylonian clay tablet YBC 7289 (c. 1800–1600 BC) with annotations. The approximation of the square root of 2 is four sexagesimal figures, which is about six decimal figures. 1 + 24/60 + 51/602 + 10/603 = 1.41421296...[1] Numerical analysis is the study of algorithms that use numerical approximation (as opposed to general symbolic manipulations) for the problems of mathematical analysis http://www.phailed.me/2013/05/introduction-to-scientific-computing-error-propagation/ (as distinguished from discrete mathematics). One of the earliest mathematical writings is a Babylonian tablet from the Yale Babylonian Collection (YBC 7289), which gives a sexagesimal numerical approximation of 2 {\displaystyle {\sqrt {2}}} , the length of the diagonal in a unit square. Being able to compute the sides of a triangle (and hence, being https://en.wikipedia.org/wiki/Numerical_analysis able to compute square roots) is extremely important, for instance, in astronomy, carpentry and construction.[2] Numerical analysis continues this long tradition of practical mathematical calculations. Much like the Babylonian approximation of 2 {\displaystyle {\sqrt {2}}} , modern numerical analysis does not seek exact answers, because exact answers are often impossible to obtain in practice. Instead, much of numerical analysis is concerned with obtaining approximate solutions while maintaining reasonable bounds on errors. Numerical analysis naturally finds applications in all fields of engineering and the physical sciences, but in the 21stcentury also the life sciences and even the arts have adopted elements of scientific computations. Ordinary differential equations appear in celestial mechanics (planets, stars and galaxies); numerical linear algebra is important for data analysis; stochastic differential equations and Markov chains are essential in simulating living cells for medicine and biology. Before the advent of modern computers numerical methods often depended on hand interpolation in large printed tables. Since the mid 20th century, computers calculate the requ
