Elements of arithmetic

Augustus De Morgan

Sinossi

Imagine a multitude of objects of the same kind assembled together; for example, a company of horsemen. One of the first things that must strike a spectator, although unused to counting, is, that to each man there is a horse. Now, though men and horses are things perfectly unlike, yet, because there is one of the first kind to every one of the second, one man to every horse, a new notion will be formed in the mind of the observer, which we express in words by saying that there is the same number of men as of horses. A savage, who had no other way of counting, might remember this number by taking a pebble for each man. Out of a method as rude as this has sprung our system of calculation, by the steps which are pointed out in the following articles. Suppose that there are two companies of horsemen, and a person wishes to know in which of them is the greater number, and also to be able to recollect how many there are in each.

In the Name of Sharks - 1st Edition

François Sarano

Twenty meters below water, the oceanographer François Sarano came face to face with a five-and-a-half-meter great white shark. Seduced by the gentle elegance of this majestic creature, Sarano experienced a profound sense of affinity with her as they swam side by side, shoulder to shoulder, eye to eye, cutting a single figure through the ocean depths. It was an experience which made him realize the depth of our ignorance of the lives of sharks, leading him to become a passionate advocate for their protection. 
 
 
 
Drawing on the latest scientific research on the biology and ethology of sharks and their exceptional characteristics, this book aims to break through the barrier of prejudice and to pay homage to their true nature. Representing a last vestige of wildness, their populations are nevertheless under threat—like so many species, they have been hunted and exploited by humans. Sarano argues for a change of mindset in which we lose ourselves in the world of the other, so that each living entity, human and non-human, can take their rightful place in the broader global ecosystem.

Eavesdropping on Animals - What...

George Bumann, John Young

Humans once relied on the calls of wild animals to understand the natural world and their place within it. Now, this remarkable guide reveals what our ancestors knew long ago—that tuning in to the owl in the tree, the deer in the gully, can tell us important information and help us feel connected to our wild community. 
 
 
 
In Eavesdropping on Animals, George Bumann shares the fascinating stories and insights he has gained from studying wildlife around the world for more than forty years, the last twenty of which have been spent leading popular programs on animal language and intelligence in Yellowstone National Park. Bumann shares tips, tricks, and advice for listeners living in urban, suburban, and rural areas and clearly shows us that you don't need an exotic vacation or a biology degree to have transformative wildlife encounters. Listening to and observing creatures in your own backyard, on nearby trails, and in local parks, seashores, fields, and forests can lead to extraordinary experiences and a profound sense of belonging. 
 
 
 
Are you ready to eavesdrop on your wild neighbors? Are you ready to learn how to tell a warning call from a mating call, a purr of satisfaction from idle chatter? Then this book is for you!

The Two-Headed Whale - Life Loss...

Sandy Winterbottom

An elegant blend of "polemic, industrial history, nautical writing, elegy, and ecology" (The Scotsman), The Two-Headed Whale charts the tragic history of the post-war whaling industry alongside the author's thrilling memoir of sailing the Antarctic. 
 
 
 
In 2016, Sandy Winterbottom embarked on an epic six-week tall-ship voyage from Uruguay to Antarctica. At the mid-way stop in South Georgia, her pristine image of the Antarctic was shattered when she discovered the dark legacy of twentieth century industrial-scale whaling. Enraged by what she found, she was quick to blame the men who undertook this whole scale slaughter, but then she stumbled upon the grave of an eighteen-year-old whaler from Edinburgh who she could not allow to bear the brunt of blame. There are two sides to every story. 
 
 
 
The Two-Headed Whale vividly brings to life the spectacular scenery and wildlife of the vast Southern Oceans, set alongside the true-life story of Anthony Ford, the boy in the grave, as he sailed the same seas and toiled in an industry where profits outranked human life. Drawing together threads of nature and travel writing with an unflinching narrative of life aboard a whaling factory ship and the legacy it left behind, The Two-Headed Whale leaves us questioning our troubled relationship with the extraordinary abundance of this planet.

The New Age of Sexism - How AI...

Laura Bates

We like to believe we're moving closer to equality, riding the wave of technological progress into a brighter, fairer future. But beneath the glossy surface of innovation lies a chilling truth: new technologies are not just failing to solve age-old inequalities—they're deepening them. 
 
 
 
In The New Age of Sexism, acclaimed author and activist Laura Bates exposes how misogyny is being coded into the very fabric of our future. From the biases embedded in artificial intelligence to the alarming rise of sex robots and the toxic dynamics of the metaverse, Bates takes listeners on a shocking journey into a world where technology is weaponized against women. 
 
 
 
This isn't a dystopian warning about what might happen. It's a harrowing account of what's happening now and the dangers we face if we don't act. With clarity and urgency, Bates reveals how these advancements are dragging society backward, reinforcing harmful stereotypes, and jeopardizing decades of progress in the fight for gender equality. 
 
 
 
Eye-opening and empowering, The New Age of Sexism is a rallying cry for awareness and action in a world where the battle for equality has entered a dangerous new frontier.
