Alienation, belonging, and a woman's 1,000-mile journey across the Andes to visit her dying uncle in Argentina.

This text combines a practical, hands-on approach to programming with the introduction of sound theoretical support focused on teaching the construction of high-quality software. A major feature of the book is the use of Design by Contract.

A behavioral scientist explores love, belongingness, and fulfillment, focusing on how modern technology can both help and hinder our need to connect. A Next Big Idea Club nominee. Millions of people around the world are not getting the physical, emotional, and intellectual intimacy they crave. Through the wonders of modern technology, we are connecting with more people more often than ever before, but are these connections what we long for? Pandemic isolation has made us even more alone. In Out of Touch, Professor of Psychology Michelle Drouin investigates what she calls our intimacy famine, exploring love, belongingness, and fulfillment and considering why relationships carried out on technological platforms may leave us starving for physical connection. Drouin puts it this way: when most of our interactions are through social media, we are taking tiny hits of dopamine rather than the huge shots of oxytocin that an intimate in-person relationship would provide. Drouin explains that intimacy is not just sex—although of course sex is an important part of intimacy. But how important? Drouin reports on surveys that millennials (perhaps distracted by constant Tinder-swiping) have less sex than previous generations. She discusses pandemic puppies, professional cuddlers, the importance of touch, “desire discrepancy” in marriage, and the value of friendships. Online dating, she suggests, might give users too many options; and the internet facilitates “infidelity-related behaviors.” Some technological advances will help us develop and maintain intimate relationships—our phones, for example, can be bridges to emotional support. Some, on the other hand, might leave us out of touch. Drouin explores both of these possibilities.

Why we need a daily dose of touch: an investigation of the effects of touch on our physical and mental well-being. Although the therapeutic benefits of touch have become increasingly clear, American society, claims Tiffany Field, is dangerously touch-deprived. Many schools have “no touch” policies; the isolating effects of Internet-driven work and life can leave us hungry for tactile experience. In this book Field explains why we may need a daily dose of touch. The first sensory input in life comes from the sense of touch while a baby is still in the womb, and touch continues to be the primary means of learning about the world throughout infancy and well into childhood. Touch is critical, too, for adults' physical and mental health. Field describes studies showing that touch therapy can benefit everyone, from premature infants to children with asthma to patients with conditions that range from cancer to eating disorders. This second edition of Touch, revised and updated with the latest research, reports on new studies that show the role of touch in early development, in communication (including the reading of others' emotions), in personal relationships, and even in sports. It describes the physiological and biological effects of touch, including areas of the brain affected by touch, and the effects of massage therapy on prematurity, attentiveness, depression, pain, and immune functions. Touch has been shown to have positive effects on growth, brain waves, breathing, and heart rate, and to decrease stress and anxiety. As Field makes clear, we enforce our society's touch taboo at our peril.

A groundbreaking book by one of the most important thinkers of our time shows how technology is warping our social lives and our inner ones Technology has become the architect of our intimacies. Online, we fall prey to the illusion of companionship, gathering thousands of Twitter and Facebook friends, and confusing tweets and wall posts with authentic communication. But this relentless connection leads to a deep solitude. MIT professor Sherry Turkle argues that as technology ramps up, our emotional lives ramp down. Based on hundreds of interviews and with a new introduction taking us to the present day, Alone Together describes changing, unsettling relationships between friends, lovers, and families.
