Par Gregory Royal Pratt. 2024
"Gregory Pratt had a rare front-row seat to the passions, problems, peculiarities, hopes, disappointments, shenanigans, and pettiness in the drama…
and farce that was Lori Lightfoot's uneasy tenure on the fifth floor at City Hall. What he delivers on these pages takes us backstage to give us a powerful, incisive portrait of the woman, the details of her mayoralty, and the many players who shared the stage." —Rick Kogan, Chicago Tribune reporter and author of A Chicago Tavern Chicago is a world-class city, but it is also a city in crisis. Crime is up, schools have repeatedly shut down due to conflict between City Hall and the powerful teachers' union, and COVID-19 only deepened the entrenched poverty, institutional racism, and endless tug of war between the city's haves and have nots. For four years, the person at the center of this storm was Lori Lightfoot. A groundbreaking figure—the first Black, gay woman to be elected mayor of a major city and only the second female mayor of Chicago—she knew the city was at a critical turning point when she took office in 2019. But the once-in-a-lifetime challenges she ended up facing were beyond anything she or anyone else saw coming. Chicago Tribune reporter Gregory Royal Pratt offers the first comprehensive behind-the-scenes look at the tumultuous single term of Mayor Lightfoot and the chaos that roiled the city and City Hall as she fought to live up to her promises to change the city's culture of corruption and villainy, reform its long-troubled police department, and make Chicago the safest big city in America. Some of Chicago's problems can be explained by forces greater than the mayor: national polarization, long-standing cultural and racial tensions, our plague years. But some are the result of Lightfoot's poor leadership at City Hall, a story that hasn't been told in full—until now.Sontag: Her Life and Work

the Best Books of the Year by: O Magazine, Milwaukee Journal Sentinel, Seattle TimesThe definitive portrait of one of the American Century’s most towering intellectuals: her writing and her radical thought, her public activism and her hidden private faceNo writer is as emblematic of the American twentieth century as Susan Sontag. Mythologized and misunderstood, lauded and loathed, a girl from the suburbs who became a proud symbol of cosmopolitanism, Sontag left a legacy of writing on art and politics, feminism and homosexuality, celebrity and style, medicine and drugs, radicalism and Fascism and Freudianism and Communism and Americanism, that forms an indispensable key to modern culture. She was there when the Cuban Revolution began, and when the Berlin Wall came down; in Vietnam under American bombardment, in wartime Israel, in besieged Sarajevo. She was in New York when artists tried to resist the tug of money—and when many gave in. No writer negotiated as many worlds; no serious writer had as many glamorous lovers. Sontag tells these stories and examines the work upon which her reputation was based. It explores the agonizing insecurity behind the formidable public face: the broken relationships, the struggles with her sexuality, that animated—and undermined—her writing. And it shows her attempts to respond to the cruelties and absurdities of a country that had lost its way, and her conviction that fidelity to high culture was an activism of its own. Utilizing hundreds of interviews conducted from Maui to Stockholm and from London to Sarajevo—and featuring nearly one hundred images—Sontag is the first book based on the writer’s restricted archives, and on access to many people who have never before spoken about Sontag, including Annie Leibovitz. It is a definitive portrait—a great American novel in the form of a biography.Fourteen: My year of darkness, and the light that followed
Par Shannon Molloy. 2020
Optioned for a major film and adapted to the stage, Fourteen is this generation&’s Holding the Man – a moving coming-of-age…
memoir about a young man&’s search for identity and acceptance in the most unforgiving and hostile of places: high school. This is a story about my fourteenth year of life as a gay kid at an all-boys rugby-mad Catholic school in regional Queensland. It was a year in which I started to discover who I was, and deeply hated what was revealed. It was a year in which I had my first crush and first devastating heartbreak. It was a year of torment, bullying and betrayal – not just at the hands of my peers, but by adults who were meant to protect me. And it was a year that almost ended tragically. I found solace in writing and my budding journalism; in a close-knit group of friends, all growing up too quickly together; and in the fierce protection of family and a mother&’s unconditional love. These were moments of light and hilarity that kept me going. As much as Fourteen is a chronicle of the enormous struggle and adversity I endured, and the shocking consequences of it all, it&’s also a tale of survival. Because I did survive.Longlisted for the 2021 ABIA Biography Book of the Year &‘Teenagers should read this book, parents should read this book.

Par Neil Comins. 2017
If you have ever wondered about space travel, now you have the opportunity to understand it more fully than ever…
before. Traveling into space and even emigrating to nearby worlds may soon become part of the human experience. Scientists, engineers, and investors are working hard to make space tourism and colonization a reality. As astronauts can attest, extraterrestrial travel is incomparably thrilling. To make the most of the experience requires serious physical and mental adaptations in virtually every aspect of life, from eating to intimacy. Everyone who goes into space sees Earth and life on it from a profoundly different perspective than they had before liftoff.Astronomer and former NASA/ASEE scientist Neil F. Comins has written the go-to book for anyone interested in space exploration. He describes the wonders that travelers will encounter—weightlessness, unparalleled views of Earth and the cosmos, and the opportunity to walk on another world—as well as the dangers: radiation, projectiles, unbreathable atmospheres, and potential equipment failures. He also provides insights into specific trips to destinations including suborbital flights, space stations, the Moon, asteroids, comets, and Mars—the top candidate for colonization. Although many challenges are technical, Comins outlines them in clear language for all readers. He synthesizes key issues and cutting-edge research in astronomy, physics, biology, psychology, and sociology to create a complete manual for the ultimate voyage.We Can Do Better Than This: An urgent manifesto for how we can shape a better world for LGBTQ+ people

not be a philosopher or a botanist, and certainly not a mathematician, to enjoy the bounty of the world around us. But is there some sort of order, a pattern, to the things that we see in the sky, on the ground, at the beach? In A Beginner's Guide to Constructing the Universe, Michael Schneider, an education writer and computer consultant, combines science, philosophy, art, and common sense to reaffirm what the ancients observed: that a consistent language of geometric design underpins every level of the universe, from atoms to galaxies, cucumbers to cathedrals. Schneider also discusses numerical and geometric symbolism through the ages, and concepts such as periodic renewal and resonance. This book is an education in the world and everything we can't see within it.Contains numerous b&w photos and illustrations.In My Skin: My Life On and Off the Basketball Court

But “the sport’s most transformative figure” (Sports Illustrated) is equally famous for making headlines off the court, for speaking out on issues of gender, sexuality, body image and self-esteem.At 6’8”, with an 88-inch wingspan and a size 17 shoe (men’s), the Phoenix Mercury star has heard every vicious insult in the book, enduring years of taunting that began in middle school and continues to this day. Through the highs and lows, Griner has learned to remain true to herself, rising above the haters trying to take her down.In her heartfelt memoir, she reflects on painful episodes in her life and describes how she came to celebrate what makes her unique—inspiring lessons she now shares. Filled with all the humor and personality Griner has become known for, In My Skin is more than a glimpse into one of the most original personalities in sports; it’s also a powerful call to readers to be true to themselves, to love who they are on the inside and out.With a 8 pages of photos.BRST Symmetry and de Rham Cohomology
Par Soon-Tae Hong. 2024
This book provides an advanced introduction to extended theories of quantum field theory and algebraic topology, including Hamiltonian quantization associated…
with some geometrical constraints, symplectic embedding and Hamilton-Jacobi quantization and Becchi-Rouet-Stora-Tyutin (BRST) symmetry, as well as de Rham cohomology. This extended new edition offers a multifaced insight into phenomenology of particles such as baryons and photons, in terms of extended objects. In particular, in the second edition, the baryons are described in hypersphere soliton model, and the photon properties are additionally included in stringy photon model and in Dirac type relativistic quantum mechanics for a photon.It offers a critical overview of the research in this area and unifies the existing literatures, employing a consistent notation. Although the results presented apply in principle to all alternative quantization schemes, special emphasis is placed on the BRST quantization and its de Rham cohomology group which contribute to a deep understanding of constrained physical theories. The book describes how solitons and other models subject to constraints include rigorous treatments of the geometrical constraints which affect the predictions themselves. The book is intended for use by any graduate-level student with quantum field and relativity theories, and it also serves as a useful reference for those working in the field. An extensive bibliography guides the reader toward the source literature on particular topics.This book offers a comprehensive collection of introductory experiments in nuclear and cosmic ray physics utilizing Geiger counters.

Passages and Knocking on Heaven’s Door uses her research into dark matter to illuminate the startling connections between the furthest reaches of space and life here on Earth.Sixty-six million years ago, an object the size of a city descended from space to crash into Earth, creating a devastating cataclysm that killed off the dinosaurs, along with three-quarters of the other species on the planet. What was its origin? In Dark Matter and the Dinosaurs, Lisa Randall proposes it was a comet that was dislodged from its orbit as the Solar System passed through a disk of dark matter embedded in the Milky Way. In a sense, it might have been dark matter that killed the dinosaurs.Working through the background and consequences of this proposal, Randall shares with us the latest findings—established and speculative—regarding the nature and role of dark matter and the origin of the Universe, our galaxy, our Solar System, and life, along with the process by which scientists explore new concepts. In Dark Matter and the Dinosaurs, Randall tells a breathtaking story that weaves together the cosmos’ history and our own, illuminating the deep relationships that are critical to our world and the astonishing beauty inherent in the most familiar things.“Science has a battle for hearts and minds on its hands….How good it feels to have Lisa Randall’s unusual blend…

Committee during the Civil Rights Movement, and raising her own children in the coalfields of West Virginia, Faith S. Holsaert has been defined by the intertwined forces of race, activism, and family. As a young woman on the front line of the Civil Rights Movement, she learned the power of contested narratives and came to understand her whiteness, her queer identity, and her stakes in overturning racism. Later in life, she confronted sexual abuse and mental illness across three generations of women in her family to find that these painful histories have played a significant role in the development of her identity as a woman, activist, and mother. Through a lifetime laid bare in prose and poetry, Holsaert beautifully quilts memoir, social history, and historic events into a gripping and inspirational narrative. This powerful and structurally innovative work lends new categories of meaning to those who would strive to find their place, hope, and sense of belonging in efforts to fight against systemic racism and lead lives characterized by openness and love.Crystallography and Crystal Chemistry

This book highlights a comprehensive introduction to the principles and calculation methods of computational optical imaging. Integrating optical imaging and…
computing technology to achieve significant performance improvements, computational optical imaging has become an active research field in optics. It has given rise to the emerging of new concepts such as computational imaging, computational measurement and computational photography. As high-performance image detectors make image measurements discrete and digital, images are mostly recorded in the form of discrete data, almost replacing the continuous medium used for pattern recording. Computational optical imaging technology has become an effective way for people to study microscopic imaging. At present, different imaging systems are composed of continuous optical elements such as lenses and prisms or discrete optical elements such as spatial light modulators or digital micro-mirror devices. The current computing technology has permeated all aspects of imaging systems and gradually promotes the digitization of optical imaging systems. This book summarizes the representative work done in this field and introduces the latest results. Computing technology plays an important bridging role between theories of optics and experimental systems, which inspires more comprehensive and in-depth research. It has the advantages of high repeatability, flexibility, strong computing power and low cost. In this multidisciplinary field, researchers in computer science, optics and information science have joined together to extend its depth and breadth. Targeting cutting-edge issues to be solved in computational optics, this book introduces a variety of methods that involve theoretical innovations and technical breakthroughs in imaging resolution, the field of view, imaging speed, and computing speed. It intends to provide a handy reference and technical support for graduate students, researchers and professionals engaged in the study and practice of computational optical imaging.Raman Spectroscopy: Advances and Applications (Springer Series in Optical Sciences #248)
Par Dheeraj Kumar Singh, Ashish Kumar Mishra, Arnulf Materny. 2024
This book highlights recent advances of spectroscopic techniques based on Raman scattering. Different applications are introduced that serve as examples…
for the versatile use of Raman techniques. Raman spectroscopy is a marker free technique, which is capable of yielding detailed information about molecular systems in a non-destructive way. This makes it a valuable tool for, e.g., material science or medical research. The access to vibrational energy and dynamics yields fundamental insights into static and dynamical structural properties of molecules being influenced by and influencing their material science or medical research environment. The better understanding of the basic building blocks of materials helps to improve the functionality in various applications. Raman spectroscopy has become a truly interdisciplinary research tool, and the ongoing development of techniques makes it attractive for growing variety of scientific and industrial applications, which will be demonstrated in the book. While the “classical” linear spontaneous Raman spectroscopy is restricted in its applicability due to low signal intensities or the excitation of strong fluorescence background, new techniques have helped to overcome such problems. Examples, presented in the book, are surface-enhanced Raman scattering (SERS), and various associated techniques are used to drastically increase signal intensity, confocal, and tip-enhanced Raman scattering (TERS) allowing for high and even sub-diffraction limited spatial resolutions, coherent anti-Stokes Raman scattering (CARS) avoiding fluorescence background and allowing for time-resolved observations of vibrational dynamics, or hyper- and resonance Raman scattering influencing the scattering based on electronic resonances, etc.
