#1 INTERNATIONAL BESTSELLER AN ADAM SAVAGE BOOK CLUB PICK The book-length answer to anyone who ever put their hand up in math class and asked, “When am I ever going to use this in the real world?” “Fun, informative, and relentlessly entertaining, Humble Pi is a charming and very readable guide to some of humanity's all-time greatest miscalculations—that also gives you permission to feel a little better about some of your own mistakes.” —Ryan North, author of How to Invent Everything Our whole world is built on math, from the code running a website to the equations enabling the design of skyscrapers and bridges. Most of the time this math works quietly behind the scenes . . . until it doesn’t. All sorts of seemingly innocuous mathematical mistakes can have significant consequences. Math is easy to ignore until a misplaced decimal point upends the stock market, a unit conversion error causes a plane to crash, or someone divides by zero and stalls a battleship in the middle of the ocean. Exploring and explaining a litany of glitches, near misses, and mathematical mishaps involving the internet, big data, elections, street signs, lotteries, the Roman Empire, and an Olympic team, Matt Parker uncovers the bizarre ways math trips us up, and what this reveals about its essential place in our world. Getting it wrong has never been more fun.

A book from the stand-up mathematician that makes math fun again! Math is boring, says the mathematician and comedian Matt Parker. Part of the problem may be the way the subject is taught, but it's also true that we all, to a greater or lesser extent, find math difficult and counterintuitive. This counterintuitiveness is actually part of the point, argues Parker: the extraordinary thing about math is that it allows us to access logic and ideas beyond what our brains can instinctively do—through its logical tools we are able to reach beyond our innate abilities and grasp more and more abstract concepts. In the absorbing and exhilarating Things to Make and Do in the Fourth Dimension, Parker sets out to convince his readers to revisit the very math that put them off the subject as fourteen-year-olds. Starting with the foundations of math familiar from school (numbers, geometry, and algebra), he reveals how it is possible to climb all the way up to the topology and to four-dimensional shapes, and from there to infinity—and slightly beyond. Both playful and sophisticated, Things to Make and Do in the Fourth Dimension is filled with captivating games and puzzles, a buffet of optional hands-on activities that entices us to take pleasure in math that is normally only available to those studying at a university level. Things to Make and Do in the Fourth Dimension invites us to re-learn much of what we missed in school and, this time, to be utterly enthralled by it.

We would all be better off if everyone saw mathematics as a practical ally. Sadly, most of us fear maths and seek to avoid it. This is because mathematics doesn't have good 'people skills' - it never hesitates to bluntly point out when we are wrong. But it is only trying to help! Mathematics is a friend which can fill the gaps in what our brains can do naturally. Luckily, even though we don't like sharing our own mistakes, we love to read about what happens when maths errors make the everyday go horribly wrong. Matt Parker explores and explains near misses and mishaps with planes, bridges, the internet and big data as a way of showing us not only how important maths is, but how we can use it to our advantage. This comedy of errors is a brilliantly told series of disaster stories with a happy ending.

“Anne Dimock is the Proust of pie and her remembrance of pies past is meant to inspire the pies to come. This is a lovely and elegant memoir.” —Garrison Keillor, bestselling author and host of A Prairie Home Companion In America, pie is a food—and a concept—that carries unusual resonance. In Humble Pie, Anne Dimock offers a delightful combination of memoir, pie quotes, inspiration, recipes, travel writing, and assorted philosophical, cultural, and culinary musings on this powerful yet humble dessert. Anne Dimock grew up in a household where, she notes, “A dearth of good pie was a hardship I never encountered, never knew must be borne up by most folk.” When she realized that the decline of the American pie civilization might be a harbinger of even deeper cultural problems, Anne became a woman on a mission to save pie from extinction. Dimock shares her thoughts on the Zen of making pie crust, the politics of pie, judging a man’s character according to his pie protocol, state fair pie competitions, the kinship between pie and baseball, and the search for edible pie at roadside diners. Folksy and full of humor, Humble Pie is more than just an evocative journey through a life lived in pie. It is a culinary manifesto for a pie renaissance, inviting readers to take up their rolling pins and revive an endangered slice of American culture. Dimock advises us all to “Roll back the apprehension, the doubt, and enter the childlike state of grace where all things are possible and anything lost can be found again. The pie you seek resides not only in memory and imagination—your next piece of pie begins right here.”

In his classic book, The Five Dysfunctions of a Team, Patrick Lencioni laid out a groundbreaking approach for tackling the perilous group behaviors that destroy teamwork. Here he turns his focus to the individual, revealing the three indispensable virtues of an ideal team player. In The Ideal Team Player, Lencioni tells the story of Jeff Shanley, a leader desperate to save his uncle’s company by restoring its cultural commitment to teamwork. Jeff must crack the code on the virtues that real team players possess, and then build a culture of hiring and development around those virtues. Beyond the fable, Lencioni presents a practical framework and actionable tools for identifying, hiring, and developing ideal team players. Whether you’re a leader trying to create a culture around teamwork, a staffing professional looking to hire real team players, or a team player wanting to improve yourself, this book will prove to be as useful as it is compelling.

2021 Mathical Honor Book Why aren’t left-handers extinct? What makes a rainbow round? How is a pancreas . . . like a pendulum? Publisher's note: It's a Numberful World was published in Australia under the title Woo's Wonderful World of Maths. These may not look like math questions, but they are—because they all have to do with patterns. And mathematics, at heart, is the study of patterns. That realization changed Eddie Woo’s life—by turning the “dry” subject he dreaded in high school into a boundless quest for discovery. Now an award-winning math teacher, Woo sees patterns everywhere: in the “branches” of blood vessels and lightning, in the growth of a savings account and a sunflower, even in his morning cup of tea! Here are twenty-six bite-size chapters on the hidden mathematical marvels that encrypt our email, enchant our senses, and even keep us alive—from the sine waves we hear as “music” to the mysterious golden ratio. This book will change your mind about what math can be. We are all born mathematicians—and It’s a Numberful World.

In this collection of stories, animal friends learn such virtues as thoughtfulness, forgiveness, thankfulness, and humility. Each story ends with a Bible verse.
