+Scientific Applications
+=======================
+
+Context
+:::::::
+
+Python is frequently used for high-performance scientific applications. Python is widely used in academia 
+and scientific projects because it is easy to write, and it performs really well. 
+
+Due to its high performance nature, scientific computing in python often refers to external libraries, typically 
+written in faster languages (like C, or FORTRAN for matrix operations). The main libraries used are NumPy and SciPy 
+
+Libraries
+:::::::::
+
+Numpy
+-----
+`NumPy <http://numpy.scipy.org/>`_ is a low level library written in C (and FORTRAN) for high level mathematical functions.
+NumPy cleverly overcomes the problem of running slower algorithms on Python by using multidimensional arrays and functions that operate on arrays.
+Any algorithm can then be expressed as a function on arrays, allowing the algorithms to be run quickly. 
+
+
+NumPy is part of the SciPy project, and is released as a separate library so people who only need the basic requirements can just use NumPy.
+
+NumPy is compatible with Python versions 2.4 through to 2.7.2 and 3.1+. 
+
+SciPy
+-----
+`SciPy <http://scipy.org/>`_ is a library that uses Numpy for more mathematical function. SciPy uses NumPy arrays as its basic data structure.
+SciPy comes with modules for various commonly used tasks in scientific programing like linear algebra, integration (calculus), 
+ordinary differential equation solvers and signal processing. 
+
+Enthought
+---------
+
+Installing NumPy and SciPy can be a daunting task. Which is why the `Enthought Python distribution <http://enthought.com/>`_ was created. With Enthought,
+scientific python has never been easier (one click to install about 100 scientific python packages). User beware: Enthought is not free. 
+
+Matplotlib
+----------
+
+.. todo:: write about matplotlib.
+
+Resources
+:::::::::
+
+Many people who do scientific computing are on Windows. And yet many of the scientific computing packages are notoriously difficult to build and install.
+`Christoph Gohlke <http://www.lfd.uci.edu/~gohlke/pythonlibs/>`_ however, has compiled a list of Windows binaries for many useful Python packages. 
+The list of packages has grown from a mainly scientific python resource to a more general list. It might be a good idea to check it out if you're on Windows.

+Web.py
+------
+
+`web.py <http://webpy.org>`_ is a minimalist web framework that is somewhere between Django and Flask. 
+The premise of web.py is that it is flexible - code your webapp any way you want it, in just python and python alone.
