Bøker av Owen O'Shea

Strange happenstances and chance encounters have puzzled us for centuries. This fun and fascinating book takes readers on a journey through the mathematics behind coincidences both famous and never-before-examined. From peculiar patterns in geometry and calculus to the famous Waring Problem, and other astonishing numerical curiosities, The Call of Coincidence begins by examining the mathematical properties that underpin everything there is. Next, author Owen O'Shea - along with fictional guides Charlie Chance and the enigmatic Dr. Moogle - reveals surprising connections and correlations throughout history, including numerical coincidences behind the reign of King Richard III, the sinking of the SS Edmund Fitzgerald, the 1996 FIFA World Cup, and much, much more. By investigating the properties, puzzles, and problems within, you will gain a newfound appreciation for the beautiful simplicity of mathematics in its many forms.Featuring surprising trivia gems alongside serious questions like why there is something rather than nothing, readers will be enriched by this exploration of remarkable number coincidences and the mathematics that make them possible - and probable.,

On 1 June 1921, at the height of Ireland's War of Independence, a cycling patrol of members of the RIC was ambushed by members of the IRA at Ballymacandy, County Kerry. After an hour of fighting, four police officers lay dead and another died a day later. Ballymacandy tells their story, and that of those who led the attack against them.

In the modern world the theory of probability is used extensively in mathematics, science, engineering, medicine and, of course, gambling. A proposition bet is one that involves the use of probability -both estimated and actual -where an individual makes an apparently attractive bet to someone who is easily deceived by the odds, which are at first glance in his favor.The Book of Proposition Bets gathers together, and reveals the true mathematics behind, over 50 classic and original proposition bets. From the famous Three Card Monty (really an exercise in the Monty Hall Paradox), to probabilities based on rolling dice and pulling playing cards, or whether or not a mark can guess 3 correct digits of a one dollar bill''s serial number (spoiler: the odds are against it), author Owen O''Shea here compiles a fascinating and engaging survey of prop bets. In addition, Part 2 of the book contains a brief history of the theory of probability and some examples of cons and scams perpetrated on the general public to this day around the world, (plus a few more mathematical proposition bets!).Whether to learn the intricacies used by hustlers, or borrow a couple of tricks for yourself, we wager that there is a high probability that readers will enjoy this entertaining and illuminating book!

Proves that math can be serious fun!If you like any kind of game at all, you''ll enjoy the amazing mathematical brainteasers in this entertaining book. No special mathematics training is needed. With an emphasis on puzzling word problems with surprising solutions, the author presents his mathematical hurdles in order of increasing difficulty. Many appear deceptively simple, such as: How many quarter-inch marks are on an unusual sixteen-inch ruler? Or: If the cost of a bottle and a cork is $1.10 and the bottle costs $1.00 more than the cork, how much did the bottle alone cost? Check the answers before you decide that these are too easy. You may be surprised.Novices may want to begin with some of the teasers in the first "easy" section. More experienced math-heads may want to test their wits with the "challenging" or even the "difficult" sections (some are fiendishly difficult). Including word problems by famed mathematical puzzle geniuses Sam Loyd (1841 - 1911) and Henry Ernest Dudeney (1857 - 1930), which have entertained recreational math aficionados for more than a century, this book has something for puzzle solvers at any level. And for the math phobic, it may whet your appetite to delve into a subject you thought could only be boring.
