A professional psychologist spent his entire life believing he had no ability or interest in sport. Then, in his forties, he became a champion ultradistance athlete before breaking the world record for the fastest bicycle crossing of Europe. This journey - made entirely alone and without any support crew - went from the northernmost point in the Arctic down to the very southernmost point in Spain. Averaging 377 kilometres each day and with up to 18 hours in the saddle at a time, the total distance of 6367 km was covered in well under 17 days, knocking more than two days off the previous record. It was a journey of ultimate self-reliance. Endless Perfect Circles is not just a tale of sleep deprivation and eating terrible food in supermarket car parks, it is also a celebration of how tough sporting challenges offer ordinary people a path to self-improvement. Weaving his own experiences together with psychological insights, Ian Walker demonstrates the rewards we can all find from setting ourselves difficult personal goals and working out how we will rise to meet these. "When I ride, my mind is both crowded and empty. The practical part of me churns, thinking all the time about navigation, shops, food, weather and lodging, seeking information about those raw essentials of life and planning dozens of contingencies. But when I look back on any given ride, even one lasting many days, I would struggle to tell you a single thought that passed through my head, because the rest of my mind has been liberated. All of life’s needs have been simplified by the pure act of riding." About the author Ian Walker splits his time across two related worlds. By day, he is an environmental psychologist at the University of Bath, specialising in transport choices, traffic safety, energy consumption and water use. As you will see from his textbooks, he also teaches research methods and statistics at a whole range of levels from entry-level introductions up to doctoral level. Ian's professional interest in clean transport and traffic safety also extends into his personal life, where he takes part in ultradistance bicycle racing - an activity explored in his new book Endless Perfect Circles. This introduces readers to the extraordinary world of nonstop bicycle races that last for weeks at a time. It goes on to describe how Ian won a tough 4300-kilometre cycle race before breaking the Guinness World Record for the fastest ever bicycle crossing of Europe.

The debut picture book from the creator of the viral sensation Kid President is a moving take on how we can create bigger and bigger circles of community and connections as we grow—now a New York Times bestseller! In the circles all around us, everywhere that we all go, there's a difference we can make and a love we can all show. This is the story of a circle. When we're first born, our circle is very small, but as we grow and build relationships, our circle keeps getting bigger and bigger to include family, friends, neighbors, community, and beyond. Brad Montague originally created Circles as an Instagram video adorably narrated by his kids, and now this picture book adaptation is the perfect way to start a conversation about how to expand our worlds with kindness and inclusivity—even if it seems scary or uncomfortable. This book makes an ideal new-baby, first-day-of-school, or graduation gift, or any milestone that celebrates someone's world getting bigger.

For the past two millennia, no significant progress has been made to improve methods used in the calculations of circles. Due to the transcendence of pi, the inner and outer dimensions of the circle were never calculated with precision, only approximately. The numeric facts were never reconciled with the geometric facts. But a breakthrough comes forth as author Lionel Fabius presents his thoroughly researched work on circles, Pi, Monads, and the Quasi-circle Theory. After some intensive and extensive study, he provides a brilliant tool that centers on circles from a numerical point of view. His concept on monad conjecture, which represents the backbone of his quasi-circle theory, allows us to compute the dimensions of a circle with unprecedented methods of calculations. His work on the circle may affect some of the fundamental concepts found in basic mathematics and may even change your view of Pi as an irrational number.

No matter how hard she tries, Triangle doesn't roll like the circles, or stack like the squares. She sets off to find friends that look exactly like her. But when she finds other triangles, playtime isn't as fun. She misses shapes that roll and stack; she misses being different. So she starts a new quest.

Diamonds, cubes, rings, and cylinders—shapes are all around us. How many shapes can you find pictured in this book?
