The subject of the book is helium, the element, and its use in myriad applications including MRI machines, particle accelerators, space telescopes, and of course balloons and blimps. It was at the birth of our Universe, or the Big Bang, where the majority of cosmic helium was created; and stellar helium production continues. Although helium is the second most abundant element in the Universe, it is actually quite rare here on Earth and only exists because of radioactive elements deep within the Earth. This book includes a detailed history of the discovery of helium, of the commercial industry built around it, how the helium we actually encounter is produced within the Earth, and the state of the helium industry today. The gas that most people associate with birthday party balloons is running out. “Who cares?” you might ask. Well, without helium, MRI machines could not function, rockets could not go into space, particle accelerators such as those used by CERN could not operate, fiber optic cables would not exist, and semiconductor chips could not be made...the list goes on and on.

At least 10 years have elapsed since a comprehensive monograph concer ned with the broad subject of cryogenics has been published. During this time a considerable quantity of research and development has been carried out in the field of cryogenics. Furthermore, there has been a certain degree of redirection of effort within the field, mostly driven by the variety of new applications, ranging from superconductive magnet systems to micro electronics. Greater emphasis is now being placed on low-temperature cryogenics, particularly that of liquid helium. Until now cryogenic books have provided a broad survey of materials and fluid properties over the entire cryogenic regime, T ::5 150 K. This approach does not allow sufficient detail in any particular area to bring the reader to the current level of understanding in the subject. In addition, the behavior of helium has been lumped with that of other cryogenic fluids, although the properties of helium are quite unique. As a result, a clear relationship has not been established between the fundamental understanding of helium fluids and their potential applications. The present book has been written to fill this void. The approach is to survey the field of cryogenics, specifically as it pertains to helium fluids. This approach is more specialized than that contained in previous cryogenics books. Furthermore, the level of treatment is more advanced and a certain knowledge of fundamental engineering and physics principles has been assumed.

There are fundamental relations between three vast areas of physics: particle physics, cosmology and condensed matter physics. The fundamental links between the first two areas, in other words, between micro- and macro-worlds, have been well established. There is a unified system of laws governing the scales from subatomic particles to the Cosmos and this principle is widely exploited in the description of the physics of the early Universe. The main goal of this book is to establish and define the connection of these two fields with condensed matter physics. According to the modern view, elementary particles (electrons, neutrinos, quarks, etc.) are excitations of a more fundamental medium called the quantum vacuum. This is the new 'aether' of the 21st Century. Electromagnetism, gravity, and the fields transferring weak and strong interactions all represent different types of the collective motion of the quantum vacuum. Among the existing condensed matter systems, a quantum liquid called superfluid 3He-A most closely represents the quantum vacuum. Its quasiparticles are very similar to the elementary particles, while the collective modes of the liquid are very similar to electromagnetic and gravitational fields, and the quanta of these collective modes are analogues of photons and gravitons. The fundamental laws of physics, such as the laws of relativity (Lorentz invariance) and gauge invariance, arise when the temperature of the quantum liquid decreases. This book is written for graduate students and researchers in all areas of physics.

The condensed phases of helium three provide an exciting laboratory for many fundamental questions in condensed matter physics. Due to its light mass and weak interatomic potential, the condensed phases of helium display quantum effects more dramatically than any other atomic system. Intuition based on classical experience is often misleading in these phases: the solid phase for instance is less ordered at low temperature than the liquid phase. The present book is unique in covering all the low temperature properties of helium three as liquid, superfluid, and solid. It provides an introduction to the extensive literature on helium three from the point of view of an experimentalist, and includes the analogy of its properties with the cosmological 'big bang'. Graduate students, researchers, and professionals in condensed matter physics and low temperature physics will find this the standard reference work for the decade to come.

Helium is the debut poetry collection by internet phenom Rudy Francisco, whose work has defined poetry for a generation of new readers. Rudy's poems and quotes have been viewed and shared millions of times as he has traveled the country and the world performing for sell-out crowds. Helium is filled with work that is simultaneously personal and political, blending love poems, self-reflection, and biting cultural critique on class, race and gender into an unforgettable whole. Ultimately, Rudy's work rises above the chaos to offer a fresh and positive perspective of shared humanity and beauty.

Once Gary had been 'Gary Wilder and the Hi-Tones - live on stage tonight'. But that was before he let everything drift away: his folks, his wife, the band, the shower curtains... And this is now - a bizarre bad hair day made worse by the reappearance of Kent Treacy, acid casualty guitarist from the days when the old surf band mutated into The High in a chemical haze. Kent's warped perspective on the gravity of Gary's situation proves unexpectedly influential as the lightness in Gary's step becomes of great interest to NASA.
