The aim of this book is to explain, carefully but not technically, the differences between advanced, research-level mathematics and the sort of mathematics we learn at school. The most fundamental differences are philosophical, and listeners of this book will emerge with a clearer understanding of paradoxical-sounding concepts such as infinity, curved space, and imaginary numbers. The first few chapters are about general aspects of mathematical thought.

Psychology is part of everyone's experience: It influences the way we think about everything from education and intelligence, to relationships and emotions, advertising and criminality. People readily behave as amateur psychologists, offering explanations for what people think, feel, and do. But what exactly are psychologists trying to do? What scientific grounding do they have for their approach? This Very Short Introduction explores some of psychology's leading ideas and their practical relevance.

This lively and engaging book is the ideal introduction for anyone who has ever been puzzled by what philosophy is or what it is for. Edward Craig argues that philosophy is not an activity born from another planet; learning about it is just a matter of broadening and deepening what most of us do already. He shows that philosophy is no mere intellectual pastime.

This lively and accessible introduction to Plato focuses on the philosophy and argument of his writings, drawing the listener into Plato's way of doing philosophy, and the general themes of his thinking. It looks at Plato as a thinker grappling with philosophical problems in a variety of ways, rather than a philosopher with a fully worked-out system. It includes a brief account of Plato's life and the various interpretations that have been drawn from the sparse remains of information.

Mark Koyama and Jared Rubin dive into the many theories of why modern economic growth happened when and where it did. They discuss recently advanced theories rooted in geography, politics, culture, demography, and colonialism. Pieces of each of these theories help explain key events on the path to modern riches. Why did the Industrial Revolution begin in eighteenth-century Britain? Why did some European countries, the United States, and Japan catch up in the nineteenth century? Why did it take until the late twentieth and twenty-first centuries for other countries?
