One of the most fundamental questions asked throughout human history is, How did the universe come into existence? Throughout the ages spirituality has provided answers to that question through various mystical cosmologies. Today, science has an answer-the Big Bang theory. But can scientific and spiritual explanations, which are normally considered to be incompatible, co-exist? Is it possible to construct a single comprehensive vision that unites these seemingly divergent approaches to knowledge? The Architecture of the Universe attempts to do just that by extending a contemporary mystical cosmology and merging it with modern-day physics. The result is a new theory of physics, which proposes something more fundamental to the universe than time and space: existence. Emerging out of nothingness, existence serves as the basic component of time and space. Time and space are viewed not just as containers for everything in the universe, but rather as the substance out of which energy and mass arise. This radical viewpoint opens new realms of understanding, shedding light on mysterious aspects of quantum mechanics and Einstein's theory of relativity. At the same time the theory creates a vision unifying science and spirituality by linking the infinite transcendent reality with the finite physical universe. Simple explanations along with illustrations make this book easily accessible and an interesting and inspiring read for a wide audience.

The Linux world is constantly changing, requiring new knowledge and skills to work as a Linux system administrator. Linux Fundamentals, Second Edition not only updates the first edition with new material, but also changes the book's focus a bit, from a basic approach to Linux to a more advanced server-oriented look at using Linux. While the first edition tracked the skills needed to meet the LPI Linux Fundamentals exam requirements, this edition tracks the more advanced CompTIA Linux+ exam requirements.The Second Edition provides a soft, accessible, and practical introduction to Linux environments and command line basics. This edition dives deeper into the Linux server environment, covering the commands you are expected to know for the Linux+ exam. The updated chapters provide expanded coverage on how to manage users, files, devices, and filesystems in a multi-user networked server environment.

LSD belongs to the class of drugs that, taken orally, can produce dramatic psychological experiences. There appears to be a wide range of response to LSD. Commonly there are reports of sensory changes, extreme variations in strong emotions, new perspectives about oneself, changed views of-and feelings toward-other people, changes from prior chronic situations, shifts in interest, and new integrative experiences which may be delusional or mystically religious.

The contributors to this volume, which was first published in 1965, accent the culture that embraces LSD. They marshal evidence that the effects of any drug tend to be in keeping with the values of the culture or subculture in which it is used, or if the user's wish is to express rebellion or dissidence, the effect will stand in opposition to prevailing values. The same substance has different effects in different cultures; and the same effects may be achieved with different substances. In the past, alcohol was hailed in much the same way as LSD. There was even a time when coffee was brought under the same kind of proscription that today holds for opiates.

Such conflicts in values and morals continue with a new generation of drugs, which makes this volume especially relevant. What could be done was an open issue at the time this book was first published. The contributors encourage citizens, scientists, physicians, mystics, ministers, lawmakers and lawmen, drug users and abstainers, to learn and to think more about the phenomena of drug use and to develop plans for social action. This volume stresses the need to develop a policy regarding the handling of classes of drugs and drug users. Although LSD has fallen in favor as a drug of choice for those interested in experimentation, the issues raised in this volume remain with us.
