Preface

Some time ago I retired, yes, retired from any tenure, curriculum, examination, and other everyday obligations, by so became free for thinking, reading, researching to my delight using as many forces from my remaining as I like. Truly speaking only as many as my wife let me put to such superfluous matter like thinking. She believes that this is only a needless pulling the mouse, pressing buttons, but mainly stretching in the pampering chair, living a live of ease. From a certain point of view she has some truth as I decided to make effort to my delight as a technique of a retired. Still it is a kind of job, a research for which I had no time in my earlier life or for the sake of God I forgot.

Anyhow I do make this work hoping there will other people being interest about.

Did you dear Reader tried anytime to gather people, friends and family together to listen you, your newest discovery in your science? If yes, than you know already what a tremendous success to have one. This is how I feel now as I have, I found even more than one such community to listen to me speaking and projecting about networks, all their meaning, working, effecting to our life, and all these coming from my sitting before a computer, pulling mouse, living my ease of life and than writing all about. The other result is this little book, a kind of collected knowledge, science about the different kind of networks. It is not at all full and of course not a curriculum, but a certain way it is a guide trough the network science, understanding this new world, these new knowledge.

Now some hints how to use this book. The simplest way just read through the table of contents and the one page long first chapter. Other people could choose the more interest from the chapters. The even deeper inquirer could read trough all of them and using the reach references also.

I have to tell you again, this is a collection work, researching for the good enough and understandable texts for each topic.

I hope you will use this either obtain knowledge or use as a breviary at work.

I wish all readers turn the leaves of this book successfully.
