A K Mallik is a Professor of Mechanical Engineering at Indian Institute of Technology, Kanpur. His research interest includes kinematics, vibration engineering. He participates in physics and mathematics education at the high-school level.

In this second part of the article we discuss how simple growth models based on Fibbonachi numbers, golden section, logarithmic spirals, etc. can explain frequently occuring numbers and curves in living objects. Such mathematical modelling techniques are becoming quite popular in the study of pattern formation in nature.
