Therefore you can expect that this book will come to your immediate help when you need. I have kept this book deliberately very simple for two main The readers don’t have time and neither do I to make it verbose. Therefore please look for text books, reference books, technical publications, Wikipedia, etc. This book is aimed at solving newer problems in technical field. Keep the key concepts that you learn here in your mind all the time – memorize them - and you will see that you will invent many solutions to the various problems not yet uncovered.
