Physics of the invisible Sun: Instrumentation, Observations, and Inferences provides a new updated perspectives of the dramatic developments in solar physics mainly after the advent of the space era. It focusses on the instrumentation exploiting the invisible windows of the electromagnetic spectrum for observing the outer, fainter layers of the Sun. It emphasizes on the several technical and observational challenges and proceeds to discuss the discoveries related to energetic phenomena occurring in the transition region and corona. The book begins with giving a brief glimpse of the historical developments during the pre-, and post-telescopic periods of visible and spectroscopic techniques, ground-based optical and radio observing sites. Various types of telescopes and back-end instrumentation are presented based on photometry, spectroscopy, and polarimetry using the Zeeman and Hanle effects for measurement of magnetic fields, and Doppler effect for radial velocity measurements. The book discusses theoretical and observational inferences based on detection of solar neutrinos, and helioseismology as the probes of the hidden solar interior, and tests of solar standard models. The characteristic properties and observational signatures of global solar p- and g-oscillations modes, developments in local helioseismology and asteroseismology are discussed. The role of the solar magnetic field and differential rotation in the activity and magnetic cycles, prediction methodologies, and dynamo models are described. Observing the Sun in IR at the longer, and the UV, EUV, XUV, X-rays, and gamma-rays at the shorter wavelengths are covered in detail. Observational challenges at each of these wavelengths are presented followed by the instrumentation for detection and imaging that have resulted in enhancing the understanding of various solar transient phenomena, such as, flares and CMEs. The outer most corona is described as a dynamic, expanding component of the Sun from the theoretical and observational perspectives of the solar wind. It then discusses the topics of the Interplanetary magnetic field, slow and fast solar wind, interaction with magnetised and non-magnetised objects of the solar system, the space weather and the physics of the heliosphere. The chapter on the future directions in solar physics presents a brief overview of the new major facilities in various observing windows, and the future possibilities of observing the Sun from ground and vantage locations in space. Features: Systematic overview of the developments in instrumentation, observational challenges and inferences derived from ground-based and space-borne solar projects. Advances in the understanding about the solar interior from neutrinos and helioseismology. Recent research results and future directions from ground- and space-based observations. This book may serve as a reference book for scientific researchers interested in multi-wavelength instrumentation and observational aspects of solar physics. It may also be used as a textbook for a graduate-level course.

When we think of astronomy, we often associate the word implicitly with observing astronomical bodies with our own eyes, or from a signal collected in the visible light range. However, there is more information we can collect from these bodies when observing them using other kinds of light, unseen to the naked eye. Radio astronomy is an important tool in an astronomer's toolkit, and can help us image hidden parts of the universe. Recently, radio astronomy was used to directly image a black hole in the center of a nearby galaxy for the first time! This projects aims to further explore the ways in which radio interferometry can broaden and enhance our understanding of distant astronomical bodies, approaching it both physically and conceptually. Specifically, I worked on the design and construction of a radio telescope here at Bard, that will be able to detect radio waves coming from the Sun. Concurrently, I worked to understand the theoretical implications of radio interferometry and how the signal would be processed and used to determine the diameter of the Sun.

The ability is see is fundamental to our very existence. How true our perceptions really are depends upon many factors, and not least is our understanding of what light is and how it interacts with matter. It was said that the camera, the icon of light recording instruments, never lies, and in the day of the glass plate and celluloid roll-film this might well have been true. But in this modern era, with electronic cameras and computer software, it is often safe to assume that the camera always lies. The advertising images that bombard our every waking moment are manipulated in shape, profile, color, and form. In this new era, light can be manipulated with metamaterials to make one object look like another or even cause that objects to vanish, literally before our eyes; not only can the image we see be manipulated, but so can the light itself.

Biosynthesis means "integration of life". It is a holistic form of body psychotherapy, which was founded over forty-five years ago. The concept of life-streams is one of its major foundations, which has since been supported by research in neurobiology. How can we integrate the three most important domains of being human: our bodily existence, our psychological experience and our spiritual essence? Biosynthesis Therapy has developed a broad spectrum of reliable methods to make this possible and to free our life energy. It is resource-oriented and is practised worldwide. David Boadella brings his many years of experience to provide in this book a trend-setting model for the understanding both of the origin of illness and of therapy. First published in 1987, this book has appeared in ten languages. It provides numerous case examples and is fascinating and enriching for the normal reader as well as for therapists from many different schools. In this book, the word "bioenergetic" is used to refer to the study of life energy, which is a major foundation of the therapy method "Biosynthesis". This is not to be confused with the term "Bioenergetic Analysis", an other and different form of body psychotherapy. Since 1985, together with David Boadella, Biosynthesis has been developed further by Dr. Silvia Specht Boadella, particularly in its philosophical and transpersonal aspects. In 1990, Biosynthesis was the first form of body psychotherapy to be scientifically accredited by the European Association of Psychotherapy. Biosynthesis therapists can therefore receive the European Certificate of Psychotherapy ECP. In 2001, the International Foundation of Biosynthesis IFB was formed, to coordinate trainings and research in twenty countries in Europe, Asia, North and South America.

He studied education, psychology and literature and wrote numerous articles and several books. Since 1985, he is the Director of the International Institute for Biosynthesis in Switzerland. In 1989, he was elected as the first President of the European Association for Body Psychotherapy EABP. In 1995, he was awarded an honorary doctorate from the "Open International University of Complementary Medicine". Author of "Wilhelm Reich: The evolution of his work" (Arkana).
