About :

This website is a culmination of notes made over years on experiments, numerical tests, and data analysis. The purpose is to document technical details including complications encountered in various projects. Software and hardware tools, such as those listed below (but not all) are acknowledged. Python, matplotlib, and associated modules (sphinx and more) have been used to prepare content for this site. IgorPro product of Wavemetrics Inc. has been used for some analysis, and LabVIEW from National Instruments for a part of the data-acquisition work.
