This book examines the huge scope of mathematical areas explored and developed by Euler, which includes number theory, combinatorics, geometry, complex variables and many more. The information known to Euler over 300 years ago is discussed, and many of his advances are reconstructed. Readers will be left in no doubt about the brilliance and pervasive influence of Euler's work.

    This book can be cut, drawn in, folded into shapes and will even take you to the fourth dimension. So join stand-up mathematician Matt Parker on a journey through narcissistic numbers, optimal dating algorithms, at least two different kinds of infinity and more.

    I’m definitely having a midlife crisis…I didn’t expect to be single at forty-five, but I’ve always prided myself on facing up to a challenge. A new town, a better job, and a cozy cottage of my own are all at the top of my To Do list. A new man? Right at the bottom. I’m far too busy for love.Returning to the Devon village of Crows Tor on Dartmoor brings a new lease of life for me – in more ways than one. It turns out my old school friend, Fiona, makes a secret moonshine at her whisky distillery using spring water collected under the full moon. Apparently it enhances your psychic powers, and she tempts me to have a shot… or three.I’m thrilled at the prospect of developing my psychic abilities. And then I look into a crystal ball at the May Day fair and have a vision of a murder. Suddenly it’s not such a fun idea after all, especially when my prediction comes true. Consumed by guilt because I didn’t warn the victim, I’m determined to find the killer, even if it puts me in the very path of danger…*The Midlife Moonshine stories are set on Dartmoor in Devon, England, and contain British English spelling and usage. They are clean reads with no graphic violence, strong language, or sex, but they’re packed with magic, mystery, romance, and history – all starring women in the prime of midlife!

    Richard Coles, led a pilgrimage to all the major historic sites of the Holy Land: from Nazareth and the Sea of Galilee in the North, via Jericho and the Jordan River, to Bethlehem and, finally, Jerusalem. All of the pilgrims in his care were practising Christians, except one: the writer Kevin Jackson, a diffident and sympathetic atheist intrigued by the chance to take part in this modern-day version of an ancient act of piety, and to learn some more about his old friend, the media clergyman.Coles to Jerusalem is Kevin Jackson’s light-hearted diary of that pilgrimage, and a close-up portrait of Richard Coles both as priest and as man. As the journey proceeds, Coles reminisces at length about his past life as a rock star and radical gay agitator, his new life as a spiritual leader and a popular broadcaster on BBC radio and television, and the strange, unpredictable path that led him from self-destructive debauchery to faith and vocation.With a lively supporting cast of fellow pilgrims, Coles to Jerusalem ranges among the magnificence of ancient monuments and the banalities of the guided tour, the grim political background of contemporary Israel and the comedy of a group of idiosyncratic English folk abroad, the intensity of worship and the lightness of banter. It will be irresistible to all admirers of Richard Coles, who has contributed a foreword; and a revelation to those who have never encountered his wisdom and warmth.

    The presentation is never awkward or dry, as it sometimes is in other "modern" textbooks; it is as unconventional as one has come to expect from the author. The book contains about 350 well placed and instructive problems, which cover a considerable part of the subject. All in all, this is an excellent work, of equally high value for both student and teacher." Zentralblatt f�r Mathematik

    As the zombie virus spreads and civilization crumbles, Williams uses calculus to help his small band of survivors defeat the hordes of the undead. Along the way, readers learn how to avoid being eaten by taking advantage of the fact that zombies always point their tangent vector toward their target, and how to use exponential growth to determine the rate at which the virus is spreading. Williams also covers topics such as logistic growth, gravitational acceleration, predator-prey models, pursuit problems, the physics of combat, and more. With the aid of his story, you too can survive the zombie onslaught.Featuring easy-to-use appendixes that explain the mathematics necessary to enjoy the book, "Zombies and Calculus" is suitable for recent converts to calculus as well as more advanced readers familiar with multivariable calculus.

Let the bidding begin! REVIEWS FOR THE TOTLANDIA SERIES “I love a good mommy send-up as much as the next gal, and this peek into the ridiculousness of the San Francisco uppercrust is delightful. Whether or not you’ve ever had the pleasure (or pain) of joining a playgroup, Brown’s tale is as charming as it is cringeworthy. I laughed, I winced, I kept scrolling.” —Romantic Times “With affairs, pending divorces, secret jobs and unsavory pasts, each wannabe member hides something that could blow her chances for good.Like the characters in reality shows such as “Dance Moms,” the women in Pacific Heights might be over-the-top, but in the end the best interests of their kids are (almost) always at heart. Laugh-out-loud funny and sometimes touching, the “Totlandia” novellas serve as the perfect quick read for busy moms or anyone looking to escape with some gossipy fun.” —Examiner.com “Josie Brown writes Totlandia with her usual storytelling flair. The dialogue is smooth and flowing. The characters are easy to side with or become angry with, depending on each situation. The scenery is easy to visualize. And we mustn’t forget all the sex (blushworthy, at that) and scandal that is a staple of a true Josie Brown novel. Totlandia: The Onesies (book one) kept me entertained and on my toes the entire time. It showed that there are mothers who are human and sometimes screw up even with the best intentions at hand. It’s like a soap opera for mommies. Guilty pleasure, anyone?!? I look forward to reading book two next and will share my thoughts on that one, as well!”—Melissa Amster, ChickLitCentral.com “This book is wonderfully written and has more than just drama. There are touching moments, parts that made me laugh out loud, and as I read the story I felt like I was reading a television show!”—Divine Secrets of a Domestic Goddess

    A "legit fan base" as my fellow "influencer" Katya Vlahos describes it, and even better, they're not made up of women who only clicked Follow to hate on me.And yes, I do know I've used more "air quotes" than what's appropriate for a single paragraph, but the thing is, that whole air quote thing also perfectly sums up my feelings about the past five years.Everything that's happened since the post is like one long air quote: I'm a nobody the whole world has mistaken for somebody, and I feel like it's only a matter of time before everyone wises up to the truth.If my life were a romance novel, I'd never be the girl who would end up with Prince Charming, and I don't think you'd even see my name pop up until Chapter Three. If my life were a romance novel, I'd just be the hero's token best friend. The kind of girl guys hang out with until they fall in love with someone else. If my life were a romance novel, someone as gorgeous as Aidan Blackwood shouldn't even know I exist...so why have I caught him checking me out like I'm his next meal?
