Excel is often mistakenly perceived simply as a business tool. This website provides an insight on how Excel software can be effectively utilised in a wide range of engineering applications. Engineering students typically use software like MATLAB or MATHEMATICA during their tertiary studies, and though in industry most engineers have access to Excel, utilization is generally limited to crunching out numbers and data storage.   

As this site illustrates, Excel is a powerful and versatile tool that can be broadly adapted to supporting a wide variety of engineering functionality and complex numerical analysis applications. A secondary objective of this site is to convey to the readers an appreciation for the understated beauty of mathematics in general, and numerical analysis in particular.  Mathematics is like art - it challenges the mind and showcases the hidden capacity and beauty of the human imagination.  

Most of the Apps on this site have been built using Microsoft Excel 2003. They will also work in Excel 2007 and Excel 2010. All Apps are provided as free downloads.
