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.

This book is an introduction to learning to do basic arithmetic mentally. The book covers elementary problems up to moderate difficulty and is written to be helpful to both students and adults in everyday situations where fast and accurate mental calculations are needed without the need for a computer or pencil and paper.

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.

According to David Hume (1743), for an event series to be a causal series is simply for that series to instantiate a regularity. According to Carl Hempel (1945), to explain an event is simply to identify a regularity of which that event is the final component. Both analyses are wrong but philosophers have failed in their attempts to identify the flaws in those arguments and, more importantly, in their attempts to produce viable alternative analyses. Here, the flaws in those arguments are identified and viable analyses of causation and explanation are put forth.

En 1637, Descartes révolutionne la manière que l'on a de faire de la géométrie : il pose les bases de ce que l'on appelle la "géométrie algébrique", qui associe, à chaque point de l'espace, 3 coordonnées. Cela permet de résoudre des problèmes géométriques avec des outils algébriques. Cette géométrie est dite "commutative", c'est-à-dire que le produit de deux quantités ne dépend pas de l'ordre des termes : A × B = B × A. Cette propriété est fondamentale, et l'ensemble de l'édifice mathématique en dépend.
