In these Messenger Lectures, originally delivered at Cornell University and recorded for television by the BBC, Richard Feynman offers an overview of selected physical laws and gathers their common features into one broad principle of invariance. He maintains at the outset that the importance of a physical law is not "how clever we are to have foundit out but…how clever nature is to pay attention to it" and steers his discussions toward a final exposition of the elegance and simplicity of all scientific laws.

Over the past few years, Brianna Wiest has gained renown for her deeply moving, philosophical writing. This new compilation of her published work features pieces on why you should pursue purpose over passion, embrace negative thinking, see the wisdom in daily routine, and become aware of the cognitive biases that are creating the way you see your life. Some of these pieces have never been seen; others have been read by millions of people around the world. Regardless, each will leave you thinking: This idea changed my life.

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.

In this collection of lectures that Richard Feynman originally gave in 1963, unpublished during his lifetime, the Nobel Prize-winning physicist discusses several of the ultimate questions of science. What is the nature of the tension between science and religious faith? Why does uncertainty play such a crucial role in the scientific imagination? Is this really a scientific age?

"Correlation does not imply causation". This mantra has been invoked by scientists for decades and has led to a virtual prohibition on causal talk. But today, that taboo is dead. The causal revolution, sparked by Judea Pearl and his colleagues, has cut through a century of confusion and placed causality - the study of cause and effect - on a firm scientific basis.

US psychologist Abraham Maslow’s A Theory of Human Motivation is a classic of psychological research that helped change the field for good. Like many field-changing thinkers, Maslow was not just a talented researcher, he was also a creative thinker - able to see things from a new perspective and show them in a different light. He studied what he called exemplary people such as Albert Einstein, Jane Addams, Eleanor Roosevelt, and Frederick Douglass rather than mentally ill or neurotic people.

Most of us believe that our happiness depends on the outside world - and that by solving our problems, improving our relationships, or achieving success, we will find contentment. In You Can Be Happy No Matter What, Dr. Richard Carlson shows that happiness has nothing to do with forces beyond our control. His simple and practical guide teaches 5 principles for discovering a new mode of living that doesn't repress natural emotions, yet where feelings and thoughts don't overwhelm us.

After the loss of her mother and her own battle with breast cancer, Joanna Teale returns to her graduate research on nesting birds in rural Illinois, determined to prove that her recent hardships have not broken her.

Both have reputations for complexity. But the basic ideas behind them are, in fact, simple and comprehensible by anyone.
