Biophysics Problems [antikvár]

prefaceThe authors have for some decades been engaged providing in biophysics lectures and laboratory practical for students majoring in physics, biology or medicine in the Departments of Biophysics at the University of Szeged and at Semmelweis University of Medicine in Budapest. Biophysics courses generally involve the teaching of considerable number of quantitative theoretical and practical concepts, and the time available is strictly limited. The presentation of a crucial equation or application to the class is often prefaced by a remark such as "it may be shown that ". The student is then left either to accept it without any deeper insight and a sense of the limitations, or to digest the concept by seeking out the derivation or the solution of a biophysics problem, often from educationally unsatisfactory research papers which abound in phrases such as "it follows that ". In many cases, such points are obvious only to the authors and the referees.In our biophysics courses, we prefer to use (homework) problems throughout the semester as a study guide. Many students are pleased to have a greater opportunity to apply the concepts of biophysics. This book will help them because it presents more than 250 biophysics problems with answers that have accumulated during many years of education. It is aimed at improving the student's problem-solving ability.The book is written for undergraduate and graduate students, i.e. readers with a general knowledge of physics, who have received introductory lectures in physical chemistry, biochemistry and biology and have some experience in practical methods of mathematical analysis. The natural sciences, including primarily physics, chemistry and biology, have made substantial contributions to the identification and analysis of biophysical problems. The boundary between the disciplines is diffuse and therefore the methods used to solve biophysics problems are widely used by other disciplines as well.The chapters are subdivided into severijJ sections, each of which starts in a rather elementary way, and progressively becomes more difficult. The introductory problems may be answered routinely in advanced courses, but can also be helpful to refresh the memory. The number of cross-references to earlier chapters is limited and therefore the reader may choose the sequence of the chapters.A textbook is not an encyclopedia. Several interesting topics in biophysics and medical physics have been omitted while others are covered. The choices reflect the authors' subjective opinion of what subjects can be discussed in the
