MATEMAX is a bilingual schoolbook of mathematical problems written with the premise that one of the fundamental ways of learning mathematics, in addition to being one of the goals of the subject, is to solve problems. The book is designed for children and young teens and aims to teach mathematics in an entertaining way. Problems are based on familiar everyday situations, and helpful hints guide students to develop strategies before diving into calculations, leading to practice in abstract thinking, an essential feature of mathematics. Presented in both English and Spanish it also provides equal access to students, parents and teachers with facility in either or both languages. An online supplement is available upon request at [email protected]. This companion book provides complete solutions, alternative methods and additional suggestions to complement the short answers contained in the book. In addition, while problems are arranged in the book as they appear naturally in life, the companion text connects the mathematical tools with standard curricula. Here is a sampling of those pages.

Aspiring and Inspiring is a collection of essays from successful women and gender minority mathematicians on what it takes to build a career in mathematics. The individual essays are intended to advise, encourage, and inspire mathematicians throughout different stages of their careers. Themes emerge as these prominent individuals describe how they managed to persist and rise to positions of leadership in a field which can still be forbidding to many. We read, repeatedly, that individual mentorship matters, that networks of support can be critical, and that finding fulfillment can mean formulating one's own definition of success. Those who aspire to leadership in the field will find much useful advice here. The cumulative power of the collection carries a strong impact. The glass ceiling is very real in mathematics and is the result of cultural and sociological factors at work in our community. The book makes clear that we won't achieve equality of opportunity merely by exhorting those who are often excluded to change their behaviors and their goals. The need for systemic cultural change is vividly, at times painfully, evident in these stories. As Dr. Erica Graham says in her powerful and moving essay, we need “a different kind of academy”, and we'll only get it by working for it. We can start by reading this book and recognizing the kind of academy we currently have.

The applications of topological techniques for understanding molecular structures have become increasingly important over the past thirty years. In this topology text, the reader will learn about knot theory, 3-dimensional manifolds, and the topology of embedded graphs, while learning the role these play in understanding molecular structures. Most of the results that are described in the text are motivated by questions asked by chemists or molecular biologists, though the results themselves often go beyond answering the original question asked. There is no specific mathematical or chemical prerequisite; all the relevant background is provided. The text is enhanced by nearly 200 illustrations and more than 100 exercises. Reading this fascinating book, undergraduate mathematics students can escape the world of pure abstract theory and enter that of real molecules, while chemists and biologists will find simple, clear but rigorous definitions of mathematical concepts they handle intuitively in their work.

In his sixth book for Thinkers Publishing, Milos Pavlovic has taken a serious look at the recent developments within the Scotch Game. Drawing upon his considerable opening experience, he investigates the most interesting and dynamic lines for White and Black, making this book a complete repertoire one. He found many novelties and highlights the most important positional and tactical themes this opening provides. We are quite convinced this 'complete repertoire book' will give you an extra boost to play this fascinating opening being one of the old-time favorites of Garry Kasparov.

Over the last 30 years, hydrographical marine surveys in the English Channel helped uncover the potential wreck sites of German submarines, or U-boats, sunk during the conflicts of World War I and World War II. Through a series of systemic dives, nautical archaeologist and historian Innes McCartney surveyed and recorded these wrecks, discovering that the distribution and number of wrecks conflicted with the published histories of U-boat losses. Of all the U-boat war losses in the Channel, McCartney found that some 41% were heretofore unaccounted for in the historical literature of World War I and World War II. This book reconciles these inaccuracies with the archaeological record by presenting case studies of a number of dives conducted in the English Channel. Using empirical evidence, this book investigates possible reasons historical inconsistencies persist and what Allied operational and intelligence-based processes caused them to occur in the first place. This book will be of interest to scholars and researchers in the fields of nautical archaeology and naval history, as well as wreck explorers.

Lars Schandorff's two volumes on 1.d4 were celebrated by reviewers and grandmasters. GM Simen Agdestein said: "I have recently been reading Lars Schandorff's Playing 1.d4 books, thinking that it cannot possibly get more instructive than this." Meanwhile, GM Boris Avrukh's verdict was simple: "Lars, I want to play your book." Now Schandorff switches sides and offers a top-class Semi-Slav repertoire against 1.d4. The Semi-Slav strikes the perfect balance of ambition and soundness, which has made it popular at every level up to and including the world championship. Black needs to know his stuff, but Schandorff is the ideal guide to make the learning process a pleasure.

Happily-ever-after is never quite what you expect in this hot and gritty romance.

More opening outrage and mayhem! The author of the 2017 groundbreaking study The Elshad System once again defies the principles of opening play - this time from White's side of the board with 1.c3, 2.Qa4, and a quick advance of the kingside pawns. In The Elshad System for White, FM Igor Nemtsev surveys Black's most common responses to this creative opening, including the King's Indian, Dutch, and big-center setups. Conventional approaches are hazardous for Black: unexpected tactics abound, and White is not afraid to sacrifice material for a sudden attack. Not even grandmasters tread safely in the Elshad minefield. Break free from the shackles of memorized variations and stereotyped book lines. Challenge your opponent on the first move with The Elshad System for White!

Knots are familiar objects. Yet the mathematical theory of knots quickly leads to deep results in topology and geometry. This work offers an introduction to this theory, starting with our understanding of knots. It presents the applications of knot theory to modern chemistry, biology and physics.
