Most books on fractals focus on deterministic fractals as the impact of incorporating randomness and time is almost absent. Further, most review fractals without explaining what scaling and self-similarity means. This book introduces the idea of scaling, self-similarity, scale-invariance and their role in the dimensional analysis. For the first time, fractals emphasizing mostly on stochastic fractal, and multifractals which evolves with time instead of scale-free self-similarity, are discussed. Moreover, it looks at power laws and dynamic scaling laws in some detail and provides an overview of modern statistical tools for calculating fractal dimension and multifractal spectrum.

He is a senior professor in the Department of Physics, Dhaka University, Bangladesh currently. His primary research interests consist of problems which are far from equilibrium. In particular, he is involved in the study of a number of non-equilibrium phenomena, including theory of percolation under phase transition and critical phenomena, complex network theory, worked rigorously on stochastic fractals and multifractals, complex network theory, kinetics of aggregation and fragmentation, monolayer growth by deposition, nucleation and growth processes. The concept of symmetry, order, scaling, similarity and self-similarity, dynamic and finite-size scaling, fractal, multifractal, power-law, data-collapse, etc. have been the key tools of his research.
