Providing a fascinating look at the science of sex and what makes people male or female, this book explains dozens of intersex conditions—such as hermaphroditism, Klinefelter syndrome, and androgen insensitivity syndrome—and includes personal interviews with people living with these conditions telling their surprising and often heart-wrenching stories. Even doctors and scientists are not entirely sure if external genitalia, internal sex organs, chromosomes, DNA, environment, or some combination define a person's sex, but this examination shows that sex is not an either-or proposition: not girl/boy, XX/XY—there are babies born XYY, XXX, or with any dozen or more known variations in the X or Y chromosomes. The history and the current treatment for intersex conditions as well as the options that are available today for the ambiguous child are covered in this captivating account that truly shows what it means to be human.

Welcome to the Matriarchy. Sixty years after a virus has wiped out almost all the men on the planet, things are pretty much just as you would imagine a world run by women might be: war has ended; greed is not tolerated; the ecological needs of the planet are always put first. In two generations, the female population has grieved, pulled together and moved on, and life really is pretty good - if you're a girl. It's not so great if you're a boy, but fourteen-year-old River wouldn't know that. Until she met Mason, she thought they were extinct.

From imaginary numbers to the fourth dimension and beyond, mathematics has always been about imagining things that seem impossible at first glance. In x+y, Eugenia Cheng draws on the insights of higher-dimensional mathematics to reveal a transformative new way of talking about the patriarchy, mansplaining and sexism: a way that empowers all of us to make the world a better place. Using precise mathematical reasoning to uncover everything from the sexist assumptions that make society a harder place for women to live to the limitations of science and statistics in helping us understand the link between gender and society, Cheng's analysis replaces confusion with clarity, brings original thinking to well worn arguments - and provides a radical, illuminating and liberating new way of thinking about the world and women's place in it.

.27 is a number Ruby hates. It's a number that marks the percentage of the population that has survived. It's a number that means she's one of the "lucky" few still standing. And it's a number that says her father is probably dead. Against all odds, Ruby has survived the catastrophic onset of the killer rain. Two weeks after the radio started broadcasting the warning, "It's in the rain. It's fatal and there's no cure," the drinkable water is running out. Ruby's left with two options: persevere on her own, or embark on a treacherous journey across the country to find her father-if he's even still alive.

Examining changing role models for masculine identity--from cowboy in the 1950s to Terminator in the 1990s, from flesh-and-blood man to machine--this book suggests that men need new role models and that sufficient room needs to be left for the expression of male vulnerability, a psychic space that would accept attitudes and behaviors traditionally labeled as "feminine." This new model, Badinter argues, may reduce the profound effects of homophobia and misogyny.

This book explains key concepts in theoretical chemistry and explores practical applications in structural chemistry. For experimentalists, it highlights concepts that explain the underlying mechanisms of observed phenomena, and at the same time provides theoreticians with explanations of the principles and techniques that are important in property design. Themes covered include conceptual and applied wave functions and density functional theory (DFT) methods, electronegativity and hard and soft (Lewis) acid and base (HSAB) concepts, hybridization and aromaticity, molecular magnetism, spin transition and thermochromism. Offering insights into designing new properties in advanced functional materials, it is a valuable resource for undergraduates of physical chemistry, cluster chemistry and structure/reactivity courses as well as graduates and researchers in the fields of physical chemistry, chemical modeling and functional materials.
