Not long ago, economic theories were generally based on a narrow set of principles. Then the continuing boom–bust cycle combined with the failure of the best economic minds to ensure that prosperity spreads down through the economy has left a series of very obvious question marks, and the orthodoxy has been challenged from inside and outside the profession. It now seems clear that human beings and the planet have to be brought into the analysis. The first chapter goes right back to the debate about the purposes for which money was originally invented.

The way humans think and behave is endlessly fascinating and often surprising. Professional psychologists spend their working lives analyzing individuals' mental processes and responses. Their subject is a science, but their practice and approach are governed by ethics and morality. We may all consider ourselves to be incidental psychologists in our daily interactions, confident of our ability to judge character, read body language, or to get to know someone, only to find ourselves confounded by seemingly unpredictable actions. Why do entirely good people sometimes do bad things? Is personality inherited or learned? Is there really such a thing as "being normal"?

Why do philosophers ask "why"? Because they want to know. Because they love knowledge. Taken literally, philosophy is nothing more (nor less) than the love (philo) of wisdom (sophia)—and who doesn't love wisdom? All human societies have developed systems of knowledge to help them understand our place in the universe and to satisfy our distinctively human curiosity. However, while standard histories of philosophy tend to focus on canonical figures and their "big ideas," ideas don't spontaneously come into existence in isolation from a context.

It's a sad truth that maths has the reputation of being "difficult." Part of the problem is that many of us simply don't speak the language. To a mathematician, an equation is a compact, efficient way to put across a relationship that would be far less comprehensible in words. But to many of us, the merest sign of an x, y, or symbol is an impenetrable mess that our eyes bounce off. This book provides an engaging overview of what maths is and what it can do, without having to solve simultaneous equations or prove geometric theorems, far more of us might get the point of it. It is divided into four chapters, each covering a major developmental route in the topic, from Arithmetic & Numbers to Geometry and from Algebra & Calculus to Applied Mathematics.

We have all heard the phrase “correlation does not equal causation.” What, then, does equal causation? This course aims to answer that question and more! Over a period of 5 weeks, you will learn how causal effects are defined, what assumptions about your data and models are necessary, and how to implement and interpret some popular statistical methods.
