Written in Stone by Polo Bourieau is an extraordinary exploration of how monumental sculpture transforms urban spaces into places of meaning and connection. From the ancient marble quarries of Carrara to the skyscrapers of Hong Kong or the bustling lanes of Chengdu, this richly illustrated book charts Polo’s creative journey, offering profound insights into the dialogue between sculpture, architecture, and community.Structured as an epic narrative inspired by Joseph Campbell’s monomyth theory, Polo’s sculptures become the protagonists of our common narrative of adventure, transformation, and identity. With reflections on the creative process and a conversation with urban planner and design writer Catherine Shaw, the book delves into the challenges and realities of creating public art in the dynamic landscapes of 21st-century China.Written in Stone offers a philosophical meditation on the power of art to shape our cities and ourselves.

A love letter to books, showing how many elements and people contribute to making something beautiful, from Caldecott honoree Elisha Cooper In this poetic and beautifully illustrated ode to creativity and the process of making books, Caldecott honoree Elisha Cooper takes readers on a journey showing how words and art move from one person to another. From writer to reader, and everyone who contributes in between: Here is a book, made with love. An artist's studio overflows with sketches, drafts, a wastebasket, and wonder. A publisher's office hums with computers, layouts, coffee, and teamwork. A printer makes a layout into a book using presses, ink, paper, and time. And that book travels to a school, to a library, to a student, to a home.

‘We must have a procedure – if we are going to hang anyone – that is just,’ said Chief Justice Sir Francis Piggott in 1909, on discovering that Chinese accused of murder were being denied interpretation in Hong Kong’s courts. Due process, no matter how costly or inconvenient, was ‘one of the penalties of empire,’ he declared.Penalties of Empire explores how judges, juries, and lawyers strove to deliver justice during the 150 years when the death penalty was in force in Hong Kong. Nine main chapters focus on key capital trials in the first century of British rule. Among the cases are piracies, assassinations, and crimes of passion and desperation. These chapters describe the proceedings in court and the participants involved. They also explore the debates surrounding each case and the exercise or denial of mercy by governors. Two final chapters discuss the decline of the death penalty after World War II, its suspension after 1966, and the controversies leading to its formal abolition in

The riveting investigative account of Nvidia, the tech company that has exploded in value for its artificial intelligence computing hardware, and Jensen Huang, Nvidia’s charismatic, uncompromising CEO In March 2024, following the revelation that ChatGPT had trained on Nvidia’s microchips, and twenty-one years after its founding in a Denny’s restaurant, Nvidia became the third most-valuable corporation on Earth.

Essential to Nvidia’s meteoric success is its visionary CEO Jensen Huang, who more than a decade ago, on the basis of a few promising scientific results, bet his entire company on AI. Through unprecedented access to Huang, his friends, his investors, and his employees, Witt documents for the first time the company’s epic rise and its ic

In this open access book, Carlos Montemayor illuminates the development of artificial intelligence (AI) by examining our drive to live a dignified life. He uses the notions of agency and attention to consider our pursuit of what is important. His method shows how the best way to guarantee value alignment between humans and potentially intelligent machines is through attention routines that satisfy similar needs.Setting out a theoretical framework for AI Montemayor acknowledges its legal, moral, and political implications and takes into account how epistemic agency differs from moral agency. Through his insightful comparisons between human and animal intelligence, Montemayor makes it clear why adopting a need-based attention approach justifies a humanitarian framework. This is an urgent, timely argument for developing AI technologies based on international human rights agreements.The ebook editions of this book are available open access under a CC BY-NC-ND 4.0 licence on bloomsburycolle
