Once you know how to see them, numbers are all around us - buried in the dimensions of buildings and encoding the data on our favourite gadgets. They’re a beautiful system of patterns and codes but also an essential tool that can guide our daily decisions, change our behaviour and even predict the future - if we can just learn how to use them right.

We've all heard that a picture is worth 1,000 words, but what if we don't understand what we're looking at? Social media has made charts, infographics, and diagrams ubiquitous - and easier to share than ever. However, they can also lead us astray. Charts lie in a variety of ways - displaying incomplete or inaccurate data, suggesting misleading patterns, and concealing uncertainty. In How Charts Lie, data visualization expert Alberto Cairo teaches us to not only spot the lies in deceptive visuals, but also to take advantage of good ones to understand complex stories.

The news media is replete with stories of corporate scandal, corruption, and misdeeds. The need for effective crisis management and corporate governance strategies has never been greater.

Leading for Organisational Change is an intelligent and practical guide to the human side of merger integration and other organizational change. Building a clear sense of common purpose and then reinforcing it through storytelling can underpin the success of an integration or significant change program. Pulling together the best thinking from neuroscience, psychology, business, and her rich personal experience in 20 years of leading change projects in professional services organizations and other people-centered businesses, author Jennifer Emery presents a framework for change.

A bite-sized mathematical sightseeing tour of the natural world from the author of The Magical Maze. Why do many flowers have five or eight petals, but very few six or seven? Why do snowflakes have sixfold symmetry? Why do tigers have stripes but leopards have spots? Mathematics is to nature as Sherlock Holmes is to evidence. Mathematics can look at a single snowflake and deduce the atomic geometry of its crystals; it can start with a violin string and uncover the existence of radio waves.

Uncertainty pervades the big decisions we all make in our lives. How much should we pay into our pensions each month? Should we take regular exercise? Expand the business? Change our strategy? Enter a trade agreement? Take an expensive holiday? We do not know what the future will hold. But we must make decisions anyway. So we crave certainties which cannot exist and invent knowledge we cannot have.

What if everything in life could be reduced to a simple formula? What if numbers were able to tell us which partners we were best matched with – not just in terms of attractiveness, but for a long-term committed marriage? Or if they could say which films would be the biggest hits at the box office, and what changes could be made to those films to make them even more successful? Or even who out of us is likely to commit certain crimes, and when?

Today, number crunching affects your life in ways you might never imagine. In this lively and groundbreaking new book, economist Ian Ayres shows how today's best and brightest organizations are analyzing massive databases at lightening speed to provide greater insights into human behavior. They are the Super Crunchers.

No number has captured the attention and imagination of people throughout the ages as much as the ratio of a circle's circumference to its diameter. Pi is infinite and, in The Joy of Pi it proves to be infinitely intriguing. With incisive historical insight and a refreshing sense of humor, David Blatner explores the many facets of pi and humankind's fascination with it - from the ancient Egyptians to the modern-day Chudnovsky brothers, who have calculated pi to eight billion digits.

Dark Data explores the many ways in which we can be blind to missing data and how that can lead us to conclusions and actions that are mistaken, dangerous, or even disastrous. Examining a wealth of real-life examples, from the Challenger shuttle explosion to complex financial frauds, Hand gives us a practical taxonomy of the types of dark data that exist and the situations in which they can arise, so that we can learn to recognize and control for them.

We solve countless problems - big and small - every day. With so much practice, why do we often have trouble making simple decisions - much less arriving at optimal solutions to important questions? Are we doomed to this muddle - or is there a practical way to learn to think more effectively and creatively? In this enlightening, entertaining, and inspiring book, Edward Burger tells us how we can become far better at solving real-world problems by learning creative puzzle-solving skills using simple, effective thinking techniques.

Can we scientifically predict our future? Scientists and pseudo scientists have been pursuing this mystery for hundreds and perhaps thousands of years. But now, astonishing new research is revealing patterns in human behavior previously thought to be purely random. Precise, orderly, predictable patterns.

The complexity of mathematics - its abstract rules and obscure symbols - can seem very distant from the everyday. There are those things that are real and present, it is supposed, and then there are mathematical concepts: creations of our mind, mysterious tools for those unengaged with the world. Yet, from its most remote history and deepest purpose, mathematics has served not just as a way to understand and order, but also as a foundation for the reality it describes.

In a rare attempt to understand the Indianness of Indians - among the most intelligent people in the world, but also, to a dispassionate eye, perhaps the most baffling - V. Raghunathan uses the props of game theory and behavioral economics to provide an insight into the difficult conundrum of why we are the way we are. He puts under the scanner our attitudes towards rationality and irrationality, selflessness and selfishness, competition and cooperation, and collaboration and deception.

For decades, statisticians, social scientists, psychologists, and economists (among them Nobel Prize winners) have spent massive amounts of precious time thinking about whether streaks actually exist. After all, a substantial number of decisions that we make in our everyday lives are quietly rooted in this one question: If something happened before, will it happen again? Is there such a thing as being in the zone? Can someone have a "hot hand"? Or is it simply a case of seeing patterns in randomness? Or, if streaks are possible, where can they be found?

Every time we download a song from iTunes, take a flight across the Atlantic or talk on our mobile phones, we are relying on great mathematical inventions. Maths may fail to provide answers to various of its own problems, but it can provide answers to problems that don't seem to be its own - how prime numbers are the key to Real Madrid's success, to secrets on the internet and to the survival of insects in the forests of North America.

Learn how to tackle tricky maths problems with nothing but the back of an envelope, a pencil and some good old-fashioned brain power. Join Rob Eastaway as he takes an entertaining look at how to figure without a calculator. Packed with amusing anecdotes, quizzes, and handy calculation tips for every situation, Maths on the Back of an Envelope is an invaluable introduction to the art of estimation and a welcome reminder that sometimes our own brain is the best tool we have to deal with numbers.

When we learn, we change what we believe and how we interact with the world. This changes who we are as people and what we can achieve. Many people grow up being told they are ‘not a maths person’ or perhaps ‘not smart’. They come to believe their potential is limited. Now, however, the latest science has revealed that our identities are constantly in flux; when we learn new things, we can change our identities, increase our potential and broaden our capacity to receive new information.

For decades, psychologists and economists have studied the science of streaks to determine whether the ‘hot hand’ exists. Is there such a thing as being in the zone? Or is it simply a case of seeing patterns in randomness? Genius scholars and Nobel Prize winners have dedicated years to answering this question. A substantial number of the decisions we make each day are rooted in two opposing beliefs: that if something happened before, it will happen again – or if it happened before, it probably won’t happen again.
