Introduction AgroMaterial Science is based on many physical disciplines, among them a key role is played by applied physics under special conditions sometimes termed as Agrophysics. It contains some parts of Biophysics, Biomechanics and some parts of Biological Physics. It contains also some parts of Chemistry, especially of Physical Chemistry and parts of Material Science, especially developed for polymers and foods. Agromaterial Science has a lot of applications in Biology of the agricultural plants and animals, as well as in Agricultural and Food Engineering. The applications are based on the descriptive mathematics formed into theories and on numerical values of critical parameters. This is the basis of problem-solving. Agromaterials belongs really to the subjects that are connected with problem-solving. In real sense, however, problem solving means grappling with a new idea or a posed question or a problem and reaching a satisfactory solution, be it a numerical value or a verbal statement. It is also a problem of data, very variable in many cases, problem of dimensions, homogeneity, isotropy, arrangements. The purpose of this guide is to help students to improve their problem-solving skills through a variety of tasks designed to foster successful techniques and strategies. Every solution is based on terms, their definitions, simplifications and mathematical description. This is a very important part of every problem-solving attempt: to find a simple but most precise expression of the problem in terms that can be described in mathematical form. The next step is to measure and/or find data that can be used as values in the theory. Every solution of the problem has to be understood as some form of estimation of the real state. This estimation should contain also some calculation of the error accompanying the estimated value. Learning to solve problems is a very complicated process that needs long-time training. A big part of this book is connected with training of problem-solving in the sphere of Agromaterials. I hope that readers enjoy the challenge of learning Agromaterials and this guide will offer some assistance toward their goal. At the end of this "Introduction" or rather "Preface" I would like to thank to Dr. Stavros Yanniotis (Agricultural University of Athens, Greece) for his help in preparing of this book, reading the text and help in the final formulations of the problems. Some parts of this book were prepared with support of the Research Intention MSM 6046070905 (Czech Republic).
