It used to take physics students two or three lab periods to complete a Fourier analysis the mathematical process that separates a sound into its components. Thanks to a computer program developed by Physics Professor Elisha R. Huggins students now do the job in seconds. Huggins's product, dubbed "MacScope," converts a Macintosh computer into a combination oscilloscope and data analysis tool. Mac Scope has been judged the best physics program in a national higher-education software competition.
