In science, as in art, there are a number of questions, eternal questions, over which generations of scientists struggle. They call them damn questions. Do we know the world? Can the mind master the secrets of nature? What is truth? Is it possible to schedule openings? How to stimulate creativity in a person? What enhances creative output? In Irina Radunskaya’s book “Cursed Questions” the reader will encounter a variety of scientific problems. Finds out how many new sciences arose and how much the framework of the old ones deepened and expanded; how aspects and tasks of nuclear physics and cosmology, particle physics and laser technology, nonlinear optics and spectral analysis are changing; what changes will high-temperature superconductors bring to our lives; what secrets are hidden in the depths of supernovae; how the achievements of nuclear magnetic resonance physics influence the progress of medicine. And most importantly, the reader will learn how scientists come to discoveries, at what price insights into the secrets of nature are obtained. In this book, as in his previous books “Crazy Ideas”, “Transformations of the Hyperboloid of Engineer Garin” , “The Collapse of Paradoxes”, “Quantums and Muses”, “Axel Berg - a Man of the 20th Century”, the trilogy “Premonitions and Accomplishments” - (“Great Mistakes”, “Ghosts”, “Unity”) and “Quintessence”, the author talks about the development of ideas, the vicissitudes of individual and collective creativity of scientists. Whatever field of science we are talking about, the main attention is focused on the heroic, intense work of physicists, mathematicians, astronomers, cosmologists, astrophysicists, work that at all times served as the foundation of human progress, the basis of civilization, the source of our knowledge about the world around us, a tool for further improvement of the human mind.
