One of the world's great mathematicians shows why math is the ultimate timesaver—and how everyone can make their lives easier with a few simple shortcuts. We are often told that hard work is the key to success. But success isn’t about hard work – it’s about shortcuts. Shortcuts allow us to solve one problem quickly so that we can tackle an even bigger one. They make us capable of doing great things. And according to Marcus du Sautoy, math is the very art of the shortcut. Thinking Better is a celebration of how math lets us do more with less. Du Sautoy explores how diagramming revolutionized therapy, why calculus is the greatest shortcut ever invented, whether you must really practice for ten thousand hours to become a concert violinist, and why shortcuts give us an advantage over even the most powerful AI. Throughout, we meet artists, scientists, and entrepreneurs who use mathematical shortcuts to change the world. Delightful, illuminating, and above all practical, Thinking Better is for anyone who has wondered why you should waste time climbing the mountain when you could go around it much faster.

Cracking Health Costs reveals the best ways for companies and small businesses to fight back, right now, against rising health care costs. This book proposes multiple, practical steps that you can take to control costs and increase the effectiveness of the health benefit. The book is all about rolling back health care costs to save companies and employees money. Working hand-in-hand with their employees, businesses need to ensure that, whenever feasible, employees with the most expensive diagnoses get optimal treatment at hospitals not practicing “volume-driven” medicine for higher profits. Less than 10% of employees incur 80% of costs. About 20% of patients have been completely misdiagnosed, while many others are simply the victims of surgeons who are either practicing bad medicine or overtreating for profit. For example, some companies, such as Walmart and Lowe’s, are turning to the “Centers of Excellence” approach author Tom Emerick helped to pioneer while running benefits for Walmart. By determining which hospitals are adopting the highest standards of care, benefits managers can reduce the number of unnecessary high-cost surgeries and improve employees’ overall health. The solution-based approach offered by the book is unique, because it can be implemented by businesses today.

This book uses elementary versions of modern methods found in sophisticated mathematics to discuss portions of "advanced calculus" in which the subtlety of the concepts and methods makes rigor difficult to attain at an elementary level.

The fundamental mathematical tools needed to understand machine learning include linear algebra, analytic geometry, matrix decompositions, vector calculus, optimization, probability and statistics. These topics are traditionally taught in disparate courses, making it hard for data science or computer science students, or professionals, to efficiently learn the mathematics. This self-contained textbook bridges the gap between mathematical and machine learning texts, introducing the mathematical concepts with a minimum of prerequisites. It uses these concepts to derive four central machine learning methods: linear regression, principal component analysis, Gaussian mixture models and support vector machines. For students and others with a mathematical background, these derivations provide a starting point to machine learning texts. For those learning the mathematics for the first time, the methods help build intuition and practical experience with applying mathematical concepts. Every chapter includes worked examples and exercises to test understanding. Programming tutorials are offered on the book's web site.

The preeminent doctor and bioethicist Ezekiel Emanuel is repeatedly asked one question: Which country has the best healthcare? He set off to find an answer. The US spends more than any other nation, nearly $4 trillion, on healthcare. Yet, for all that expense, the US is not ranked #1 -- not even close. In Which Country Has the World's Best Healthcare? Ezekiel Emanuel profiles eleven of the world's healthcare systems in pursuit of the best or at least where excellence can be found. Using a unique comparative structure, the book allows healthcare professionals, patients, and policymakers alike to know which systems perform well, and why, and which face endemic problems. From Taiwan to Germany, Australia to Switzerland, the most inventive healthcare providers tackle a global set of challenges -- in pursuit of the best healthcare in the world.

Banish math anxiety and give students of all ages a clear roadmap to success Mathematical Mindsets provides practical strategies and activities to help teachers and parents show all children, even those who are convinced that they are bad at math, that they can enjoy and succeed in math. Jo Boaler—Stanford researcher, professor of math education, and expert on math learning—has studied why students don't like math and often fail in math classes. She's followed thousands of students through middle and high schools to study how they learn and to find the most effective ways to unleash the math potential in all students. There is a clear gap between what research has shown to work in teaching math and what happens in schools and at home. This book bridges that gap by turning research findings into practical activities and advice. Boaler translates Carol Dweck's concept of 'mindset' into math teaching and parenting strategies, showing how students can go from self-doubt to strong self-confidence, which is so important to math learning. Boaler reveals the steps that must be taken by schools and parents to improve math education for all. Mathematical Mindsets: Explains how the brain processes mathematics learning Reveals how to turn mistakes and struggles into valuable learning experiences Provides examples of rich mathematical activities to replace rote learning Explains ways to give students a positive math mindset Gives examples of how assessment and grading policies need to change to support real understanding Scores of students hate and fear math, so they end up leaving school without an understanding of basic mathematical concepts. Their evasion and departure hinders math-related pathways and STEM career opportunities. Research has shown very clear methods to change this phenomena, but the information has been confined to research journals—until now. Mathematical Mindsets provides a proven, practical roadmap to mathematics success for any student at any age.

Phillip Longman tells the amazing story of the turnaround of the Department of Veterans Affairs health-care system from a dysfunctional, scandal-prone bureaucracy into the benchmark for high-quality medicine in the United States. Best Care Anywhere shows that vast swaths of what we think we know about health, health care, and medical economics are just plain wrong. And the book demonstrates how this extraordinarily cost-effective model, which has proven to be highly popular with veterans, can be made available to everyone. New to this edition is an analysis of how the shortcomings of both so-called Obamacare and Republican plans to privatize Medicare reinforce the need for applying the lessons of the VA. Also included are completely updated statistics and research, as well as examples of how the private sector is already beginning to learn from the VA's example.
