. Historical and current data indicate that the need for science and engineering careers isincreasing, yet the number of students choosing and completing traditional science degrees isdecreasing. The decrease in students choosing and/or being qualified to enter science andengineering fields is continuing even with the programs geared towards increasing awarenessand preparedness. The gap between students entering science and engineering (S&E) fields andgraduating to meet the S&E employment needs was first noted in the early 1990’s. Manyresearchers suggested that recruitment and retention into the qualitative science fields shouldinclude women and minorities to assist in filling in the employment gap.

Many women assistantprofessors are cognizant of this additional disadvantage and are choosing to postpone havingchildren. Almost half of them say the decision was made because of their careers.

Beginning in the late 1910's and into the 1920's, Julia11and Fatou12 led the study of these self-similar structures. At that time, there were no computersto produce the images that we see today.
