Conjectures and Refutations is one of Karl Popper's most wide-ranging and popular works, notable not only for its acute insight into the way scientific knowledge grows, but also for applying those insights to politics and to history. It provides one of the clearest and most accessible statements of the fundamental idea that guided his work: not only our knowledge, but our aims and our standards, grow through an unending process of trial and error.

Described by the philosopher A.J. Ayer as a work of 'great originality and power', this book revolutionized contemporary thinking on science and knowledge. Ideas such as the now legendary doctrine of 'falsificationism' electrified the scientific community, influencing even working scientists, as well as post-war philosophy. This astonishing work ranks alongside The Open Society and Its Enemies as one of Popper's most enduring books and contains insights and arguments that demand to be read to this day.

'Never before has there been so many and such dreadful weapons in so many irresponsible hands.' - Karl Popper, from the Preface All Life is Problem Solving is a stimulating and provocative selection of Popper's writings on his main preoccupations during the last twenty-five years of his life. This collection illuminates Popper's process of working out key formulations in his theory of science, and indicates his view of the state of the world at the end of the Cold War and after the collapse of communism.

Hailed by many as the world's greatest harmonica player, John Popper has redefined the instrument. As the lead singer and principal songwriter of Blues Traveler, Popper has performed for more than 30 million people over 2,000 live dates and composed such radio staples as "Hook," "But Anyway," and "Run-Around," the longest-charting single in Billboard history. He has appeared with Eric Clapton and B. B. King at the White House, welcomed the Hungarian ambassador to the stage, and inducted Carlos Santana into the Rock and Roll Hall of Fame. In Suck and Blow, Popper shares a candid, spirited account of his life and career. A straight-F student at Princeton High School, Popper's life changed with one serendipitous harmonica solo that captured the attention of his mercurial band teacher (the same teacher whose life was later fictionalized in the Academy Award-winning film Whiplash). After befriending three fellow musicians with whom he would form Blues Traveler, Popper's academic career nearly ended in twelfth grade, until a meeting with the Dean of the New School for Social Research in which Popper pulled out his trusty harp and played his way into college. Popper and Blues Traveler soon became enmeshed in the lower Manhattan music scene of the late 1980s, eventually becoming the house band at the fabled Wetlands Preserve and embarking on a journey that would one day land the group at Madison Square Garden on New Year's Eve. Along the way, Popper and his cohorts commanded the attention of fans and bands alike, through inspired performances and riotous debauchery. Popper's unique perspective on the music business began under the tutelage of Blues Traveler's mentor and manager Bill Graham. After the rock impresario's untimely passing, Popper applied many of Graham's lessons to the formation of the H.O.R.D.E. tour, which John co-owned and hosted over eight years, welcoming such artists as Neil Young, the Allman Brothers Band, Phish, Dave Matthews Band, Ziggy Marley, and his longtime friends the Spin Doctors. Popper also shares a forthright assessment of his longstanding battle with obesity. Plagued by weight problems since childhood, a motorcycle accident a few years into his career confined him to a wheelchair for two years while his weight ballooned to 436 pounds. Angioplasty, gastric bypass surgery, and a tattoo on his chest that reads "I Want to Be Brave" when viewed in the mirror are products of Popper's struggle, compounded by codependency issues and the untimely death of founding Blues Traveler bassist Bobby Sheehan. Popper's personal identity is entwined with his political passions. A staunch supporter of gun rights, he has performed at the National Republican Convention, yet he also maintains liberal positions on social issues. He will reconcile these views and share his encounters with the Bush family, the Clintons, the Gores, and other politicos. The iconoclastic, self-described Johnny Appleharp also dishes on cutting contests, Twitter trolls, party fouls, and prostitutes. In Suck and Blow, John Popper does it all with his signature honesty, humility, and humor. /DIV

From two-time National Book Award finalist Eliot Schrefer comes an original penguin-tastic adventure inspired by the beloved classic Mr. Popper's Penguins. It's been years and years since the Popper family lived in Stillwater, but the town is still riding high on its former penguin residents.

There's a lot to do: unpacking, scrubbing the floors, investigating the basement -- wait, what's this? Two penguin eggs are tucked snugly near the furnace! It's up to Nina and Joe to find their newly hatched penguin chicks a home. Setting off on the adventure of a lifetime, they endure perilous storms, a long journey to the Arctic, and of course, penguins. Lots and lots of Popper penguins!

This classic reissue of a Finnish fairy tale first published in 1964 tells the story of twin pixie brothers who find their family a new home. Button and Popper tells the story of a family of pixies—mother, father, and twelve children—who live in an apple tree. They enjoy its warmth and shelter, eating apple pie all spring and summer long. But when fall comes, the leaves begin to drop and the apple tree becomes a cold and wet place to live. Twin brothers Button and Popper decide to find their family a new home, but when they trek into the city and start inquiring about an apartment with room for twelve children and their parents, people laugh in their faces or politely excuse themselves. Luck strikes when, through a most fortunate mix-up at the market, the pixies find themselves in the home of Professor Pilli. When he hears their story, he invites them to look after his house while he’s away at the South Pole. When the rest of their pixie family finds out the good news, everyone is relieved and happy again. First published in 1964, Button and Popper was written and illustrated by Oili Tanninen, one of Finland’s most celebrated illustrators and authors. Bold, on-trend, midcentury illustrations support this new translation of a classic Finnish story that’s quirky and charming in equal measure.
