{ "item_title" : "Failure At N=80", "item_author" : [" Jason Earls "], "item_description" : "Failure At N = 80: Recreational Number Theory for the Reckless is an unusual, playful, and quietly serious book about what it feels like to live inside numerical ideas for too long. Half legitimate math articles, half short story anthology, it moves back and forth between real recreational number theory-proofs, computations, patterns, failed conjectures-and fictional stories where mathematics shows up in police cars, dish pits, campsites, operating rooms, and cold nights under bridges. The math is genuine throughout: primes, iteration problems, brilliant numbers, growth rates, Fermat-style factorizations. Nothing here is decorative. Even when wrapped in narrative, the mathematics could stand on its own if stripped bare. The nonfiction articles read like records of obsession rather than textbook lectures. They begin with curiosity, wander through computation, sometimes succeed, sometimes end in a short proof or two, and occasionally stop simply because the author ran out of patience or sanity. Proofs are careful but not precious. Chapter titles like Number of Iterations in Fermat's Factorization Method, Representations of Integers as Fibonaccis Plus Primes, and Primes in Short Intervals Above Powers of Ten signal the tone: serious ideas approached recklessly. These pieces are honest accounts of fascination, complete with computational experiments and dead ends that still feel worth the detour. Between these essays are stories that lean lighter on exposition and heavier on atmosphere. They follow people who think mathematically even when they shouldn't, who carry numbers into places where numbers don't belong, and who discover-sometimes accidentally-that mathematics has emotional weight. There's humor throughout, and a quiet, unplanned theme slowly reveals itself beneath the surface. The author has spent years chasing strange patterns in numbers-sometimes with a computer, sometimes with nothing but pencil and curiosity-and here he lets you tag along for the ride. This is not a polished survey of number theory, and it is not written to convince anyone that math is respectable. It's written for readers who enjoy poking at ideas, following strange computations, and watching mathematics behave like something alive. Earls admits upfront that he wrote it mostly for himself, assuming almost nobody would care. If you're holding this book, you're already proving him wrong.", "item_img_path" : "https://covers4.booksamillion.com/covers/bam/1/29/181/933/1291819339_b.jpg", "price_data" : { "retail_price" : "24.00", "online_price" : "24.00", "our_price" : "24.00", "club_price" : "24.00", "savings_pct" : "0", "savings_amt" : "0.00", "club_savings_pct" : "0", "club_savings_amt" : "0.00", "discount_pct" : "10", "store_price" : "" } }
