What is time? What does it mean for time to pass? Is it possible to travel in time? What is the difference between the past and future? Until the work of Newton, these questions were purely topics of philosophical speculation. Since then we've learned a great deal about time, and its study has moved from a subject of philosophical reflection to instead became part of the subject matter of physics.

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 Very Short Introduction gives an overview of what CBT is, where it came from, what it does, and when it can be used. It explores how one of the driving forces behind CBT's success and continued adaptation has been its basis in empiricism, and analyses how it must continue to evolve to meet future challenges. Freda McManus also discusses how the scale of mental health problems and relative costs of traditional therapy formats have prompted investigations into alternative formats of CBT that have the potential to reach broader audiences, globally.

Quantum theory is the most revolutionary discovery in physics since Newton. This book gives a lucid, exciting, and accessible account of the surprising and counterintuitive ideas that shape our understanding of the sub-atomic world. It does not disguise the problems of interpretation that still remain unsettled 75 years after the initial discoveries. Uncertainty, probabilistic physics, complementarity, the problematic character of measurement, and decoherence are among the many topics discussed.

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.

Millions of people around the world are healing illnesses with cannabis. Nonetheless, many physicians remain reluctant to discuss cannabis medicine with their patients. And with so much conflicting misinformation from unreliable sources, finding out if cannabis could be an effective treatment for you or a loved one can feel nearly impossible.

Our understanding of cancer is slowly undergoing a revolution, allowing for the development of more effective treatments. For the first time ever, the death rate from cancer is showing a steady decline...but the “War on Cancer” has hardly been won. In The Cancer Code, Dr. Jason Fung offers a revolutionary new understanding of this invasive, often fatal disease - what it is, how it manifests, and why it is so challenging to treat.

In this revolutionary work - a landmark that signals the true beginning of feminist medicine - a doctor, a philosopher, and a scientist prove that by postponing marriage and motherhood, women have accelerated the aging process, resulting in earlier menopause and, ultimately for thousands, earlier death. In Sex, Lies, and Menopause, they offer strong evidence that the use of synthetic hormones leads to cancer and advise women to turn to natural hormone-replacement therapy to help them elevate their estrogen level for greater energy, libido, and intellectual capacity.
