From the Solway Firth in the south to Shetland in the north, from remote St Kilda to the west to St Abbs in the east, Tom Weir explores Scotland as a walker and climber, and along the way introduces his readers to the range of wildlife and people living in the countryside, and historical aspects of various places. To his vivid descriptive writing he adds memories of some absent friends, and also retraces the path of Bonnie Prince Charlie on the run after Culloden. Tom Weir became a household name in Scotland as a result of the television series in which he explored his native country, but the book 'Weir's Way' is, to quote the author, 'not about every "e;Weir's Way"e; programme ... it is a broader vision of Scotland using the medium of written words'.

#1 NEW YORK TIMES BESTSELLER • From the author of The Martian, a lone astronaut must save the earth from disaster in this “propulsive” (Entertainment Weekly), cinematic thriller full of suspense, humor, and fascinating science—in development as a major motion picture starring Ryan Gosling. HUGO AWARD FINALIST • ONE OF THE YEAR’S BEST BOOKS: Bill Gates, GatesNotes, New York Public Library, Parade, Newsweek, Polygon, Shelf Awareness, She Reads, Kirkus Reviews, Library Journal • “An epic story of redemption, discovery and cool speculative sci-fi.”—USA Today “If you loved The Martian, you’ll go crazy for Weir’s latest.”—The Washington Post Ryland Grace is the sole survivor on a desperate, last-chance mission—and if he fails, humanity and the earth itself will perish. Except that right now, he doesn’t know that. He can’t even remember his own name, let alone the nature of his assignment or how to complete it. All he knows is that he’s been asleep for a very, very long time. And he’s just been awakened to find himself millions of miles from home, with nothing but two corpses for company. His crewmates dead, his memories fuzzily returning, Ryland realizes that an impossible task now confronts him. Hurtling through space on this tiny ship, it’s up to him to puzzle out an impossible scientific mystery—and conquer an extinction-level threat to our species. And with the clock ticking down and the nearest human being light-years away, he’s got to do it all alone. Or does he? An irresistible interstellar adventure as only Andy Weir could deliver, Project Hail Mary is a tale of discovery, speculation, and survival to rival The Martian—while taking us to places it never dreamed of going.

Nominated as one of America’s best-loved novels by PBS’s The Great American Read Six days ago, astronaut Mark Watney became one of the first people to walk on Mars. Now, he's sure he'll be the first person to die there. After a dust storm nearly kills him and forces his crew to evacuate while thinking him dead, Mark finds himself stranded and completely alone with no way to even signal Earth that he’s alive—and even if he could get word out, his supplies would be gone long before a rescue could arrive. Chances are, though, he won't have time to starve to death. The damaged machinery, unforgiving environment, or plain-old "human error" are much more likely to kill him first. But Mark isn't ready to give up yet. Drawing on his ingenuity, his engineering skills—and a relentless, dogged refusal to quit—he steadfastly confronts one seemingly insurmountable obstacle after the next. Will his resourcefulness be enough to overcome the impossible odds against him?

In 1871 two brothers, George and James Weir, founded the engineering firm of G. & J. Weir, one of a booming range of industry on the west coast of Scotland. At their Cathcart works in Glasgow the Weirs produced their own groundbreaking inventions, all crucial to the development of steam ships at that time. Today, 130 turbulent years later, the Weir Group is almost the last of those once-flourishing companies still to retain its independence and its Scottish base. Over the intervening century, Weirs manufactured pumps and valves for ships' engines around the world, oil pipelines and desalination plants, armaments (in the two world wars), and heavy equipment for power stations. Along the way it was briefly involved in autogiros (the precursor of the helicopter). Rooted in the inventiveness and determination of the Victorian manufacturing age, Weirs adapted to the changing world of the twentieth century, determined always to diversify, win overseas contracts, build partnerships and above all survive. This fascinating story is told by William Weir, a past chairman and chief executive of the company. Combining reminiscence and colourful anecdote with cool analysis of the company's triumphs and failures, this is an unusual company history and an invaluable record of a Scottish engineering legend.

Side weirs are widely used to divert or discharge flows from reservoirs, rivers, artificial channels and sewers. The hydraulic behaviour of this type of weir is complex and difficult to predict accurately using simple methods and the diversity of applictions of side weirs has the potential to complicate guidance. This manual covers the fundamental hydraulic principles and discusses the practical design issues separately for each main strcuture type.

The bestselling author of The Martian returns with an irresistible new near-future thriller—a heist story set on the moon. Jasmine Bashara never signed up to be a hero. She just wanted to get rich. Not crazy, eccentric-billionaire rich, like many of the visitors to her hometown of Artemis, humanity’s first and only lunar colony. Just rich enough to move out of her coffin-sized apartment and eat something better than flavored algae. Rich enough to pay off a debt she’s owed for a long time. So when a chance at a huge score finally comes her way, Jazz can’t say no. Sure, it requires her to graduate from small-time smuggler to full-on criminal mastermind. And it calls for a particular combination of cunning, technical skills, and large explosions—not to mention sheer brazen swagger. But Jazz has never run into a challenge her intellect can’t handle, and she figures she’s got the ‘swagger’ part down. The trouble is, engineering the perfect crime is just the start of Jazz’s problems. Because her little heist is about to land her in the middle of a conspiracy for control of Artemis itself. Trapped between competing forces, pursued by a killer and the law alike, even Jazz has to admit she’s in way over her head. She’ll have to hatch a truly spectacular scheme to have a chance at staying alive and saving her city. Jazz is no hero, but she is a very good criminal. That’ll have to do. Propelled by its heroine’s wisecracking voice, set in a city that’s at once stunningly imagined and intimately familiar, and brimming over with clever problem-solving and heist-y fun, Artemis is another irresistible brew of science, suspense, and humor from #1 bestselling author Andy Weir.

Labyrinth spillways are almost as old as dam engineering. In spite of the fact that they appear as a very good technical-economical compromise, only 0.1% of large dams are equipped with such weirs. The main reason for this is that traditional labyrinth weirs usually cannot be installed on top of concrete gravity dams as they require a large foundat
