Timely and profound philosophical meditations on how great figures in history, literature, music, and art searched for solace while facing tragedies and crises, from the internationally renowned historian of ideas and Booker Prize finalist Michael Ignatieff When we lose someone we love, when we suffer loss or defeat, when catastrophe strikes―war, famine, pandemic―we go in search of consolation. Once the province of priests and philosophers, the language of consolation has largely vanished from our modern vocabulary, and the places where it was offered, houses of religion, are often empty. Rejecting the solace of ancient religious texts, humanity since the sixteenth century has increasingly placed its faith in science, ideology, and the therapeutic. How do we console each other and ourselves in an age of unbelief? In a series of lapidary meditations on writers, artists, musicians, and their works―from the books of Job and Psalms to Albert Camus, Anna Akhmatova, and Primo Levi―esteemed writer and historian Michael Ignatieff shows how men and women in extremity have looked to each other across time to recover hope and resilience. Recreating the moments when great figures found the courage to confront their fate and the determination to continue unafraid, On Consolation takes those stories into the present, movingly contending that we can revive these traditions of consolation to meet the anguish and uncertainties of our precarious twenty-first century.

Network science is the field dedicated to the investigation and analysis of complex systems via their representations as networks. We normally model such networks as graphs: sets of nodes connected by sets of edges and a number of node and edge attributes. This deceptively simple object is the starting point of never-ending complexity, due to its ability to represent almost every facet of reality: chemical interactions, protein pathways inside cells, neural connections inside the brain, scientific collaborations, financial relations, citations in art history, just to name a few examples. If we hope to make sense of complex networks, we need to master a large analytic toolbox: graph and probability theory, linear algebra, statistical physics, machine learning, combinatorics, and more. This book aims at providing the first access to all these tools. It is intended as an "Atlas", because its interest is not in making you a specialist in using any of these techniques. Rather, after reading this book, you will have a general understanding about the existence and the mechanics of all these approaches. You can use such an understanding as the starting point of your own career in the field of network science. This has been, so far, an interdisciplinary endeavor. The founding fathers of this field come from many different backgrounds: mathematics, sociology, computer science, physics, history, digital humanities, and more. This Atlas is charting your path to be something different from all of that: a pure network scientist.

Why people are not as gullible as we think Not Born Yesterday explains how we decide who we can trust and what we should believe―and argues that we're pretty good at making these decisions. In this lively and provocative book, Hugo Mercier demonstrates how virtually all attempts at mass persuasion―whether by religious leaders, politicians, or advertisers―fail miserably. Drawing on recent findings from political science and other fields ranging from history to anthropology, Mercier shows that the narrative of widespread gullibility, in which a credulous public is easily misled by demagogues and charlatans, is simply wrong. Why is mass persuasion so difficult? Mercier uses the latest findings from experimental psychology to show how each of us is endowed with sophisticated cognitive mechanisms of open vigilance. Computing a variety of cues, these mechanisms enable us to be on guard against harmful beliefs, while being open enough to change our minds when presented with the right evidence. Even failures―when we accept false confessions, spread wild rumors, or fall for quack medicine―are better explained as bugs in otherwise well-functioning cognitive mechanisms than as symptoms of general gullibility. Not Born Yesterday shows how we filter the flow of information that surrounds us, argues that we do it well, and explains how we can do it better still.

In early 2020, because of COVID-19, many colleges and schools around the world closed, and many teachers, instructors, and faculty members had to learn how to teach online in a hurry. This book takes a step back, and focuses on helping educators teach effective live online sessions with Zoom. Dan Levy offers practical pedagogical advice for educators on questions such as:•Why and how to use breakout rooms?•Should you use chat, and if so, how?•How do you build community in a virtual classroom?The book is based on the author’s experience teaching online, observations of several colleagues teaching online at Harvard University, research-based principles of effective teaching and learning, and, perhaps just as importantly, interviews with dozens of students who recently experienced online learning for the first time and also had to adapt to this way of learning in a hurry.

From a Harvard scholar and former Obama official, a powerful proposal for curtailing violent crime in America Urban violence is one of the most divisive and allegedly intractable issues of our time. But as Harvard scholar Thomas Abt shows in Bleeding Out, we actually possess all the tools necessary to stem violence in our cities. Coupling the latest social science with firsthand experience as a crime-fighter, Abt proposes a relentless focus on violence itself -- not drugs, gangs, or guns. Because violence is "sticky," clustering among small groups of people and places, it can be predicted and prevented using a series of smart-on-crime strategies that do not require new laws or big budgets. Bringing these strategies together, Abt offers a concrete, cost-effective plan to reduce homicides by over 50 percent in eight years, saving more than 12,000 lives nationally. Violence acts as a linchpin for urban poverty, so curbing such crime can unlock the untapped potential of our cities' most disadvantaged communities and help us to bridge the nation's larger economic and social divides. Urgent yet hopeful, Bleeding Out offers practical solutions to the national emergency of urban violence -- and challenges readers to demand action.
