“Science is art,” said Regina Dugan, senior executive at Google and former director of DARPA. “It is the process of creating something that never exists before. ... It makes us ask new questions about ourselves, others; about ethics, the future.” This second volume of the Digital Da Vinci book series leads the discussions on the world’s first computer art in the 1950s and the actualization of Star Trek’s holodeck in the future with the help of artificial intelligence and cyborgs. In this book, Gavin Sade describes experimental creative practices that bring together arts, science and technology in imaginative ways; Mine Özkar expounds visual computation for good designs based on repetition and variation; Raffaella Folgieri, Claudio Lucchiari, Marco Granato and Daniele Grechi introduce BrainArt, a brain-computer interface that allows users to create drawings using their own cerebral rhythms; Nathan Cohen explores artificially created spaces that enhance spatial awareness and challenge our perception of what we encounter; Keith Armstrong discusses embodied experiences that affect the mind and body of participating audiences; Diomidis Spinellis uses Etoys and Squeak in a scientific experiment to teach the concept of physical computing; Benjamin Cowley explains the massively multiplayer online game “Green My Place” aimed at achieving behavior transformation in energy awareness; Robert Niewiadomski and Dennis Anderson portray 3-D manufacturing as the beginning of common creativity revolution; Stephen Barrass takes 3-D printing to another dimension by fabricating an object from a sound recording; Mari Velonaki examines the element of surprise and touch sensing in human-robot interaction; and Roman Danylak surveys the media machines in light of Marshall McLuhan’s dictum “the medium is the message.” Digital Da Vinci: Computers in the Arts and Sciences is dedicated to polymathic education and interdisciplinary studies in the digital age empowered by computer science. Educators and researchers ought to encourage the new generation of scholars to become as well rounded as a Renaissance man or woman.

A singular fatality has ruled the destiny of nearly all the most famous of Leonardo da Vinci's works. Two of the three most important were never completed, obstacles having arisen during his life-time, which obliged him to leave them unfinished; namely the Sforza Monument and the Wall-painting of the Battle of Anghiari, while the third—the picture of the Last Supper at Milan—has suffered irremediable injury from decay and the repeated restorations to which it was recklessly subjected during the XVIIth and XVIIIth centuries. Nevertheless, no other picture of the Renaissance has become so wellknown and popular through copies of every description. Vasari says, and rightly, in his Life of Leonardo, "that he laboured much more by his word than in fact or by deed", and the biographer evidently had in his mind the numerous works in Manuscript which have been preserved to this day. To us, now, it seems almost inexplicable that these valuable and interesting original texts should have remained so long unpublished, and indeed forgotten. It is certain that during the XVIth and XVIIth centuries their exceptional value was highly appreciated. This is proved not merely by the prices which they commanded, but also by the exceptional interest which has been attached to the change of ownership of merely a few pages of Manuscript. That, notwithstanding this eagerness to possess the Manuscripts, their contents remained a mystery, can only be accounted for by the many and great difficulties attending the task of deciphering them. The handwriting is so peculiar that it requires considerable practice to read even a few detached phrases, much more to solve with any certainty the numerous difficulties of alternative readings, and to master the sense as a connected whole. Vasari observes with reference to Leonardos writing: "he wrote backwards, in rude characters, and with the left hand, so that any one who is not practised in reading them, cannot understand them". The aid of a mirror in reading reversed handwriting appears to me available only for a first experimental reading. Speaking from my own experience, the persistent use of it is too fatiguing and inconvenient to be practically advisable, considering the enormous mass of Manuscripts to be deciphered. And as, after all, Leonardo's handwriting runs backwards just as all Oriental character runs backwards—that is to say from right to left—the difficulty of reading direct from the writing is not insuperable. This obvious peculiarity in the writing is not, however, by any means the only obstacle in the way of mastering the text. Leonardo made use of an orthography peculiar to himself; he had a fashion of amalgamating several short words into one long one, or, again, he would quite arbitrarily divide a long word into two separate halves; added to this there is no punctuation whatever to regulate the division and construction of the sentences, nor are there any accents—and the reader may imagine that such difficulties were almost sufficient to make the task seem a desperate one to a beginner. It is therefore not surprising that the good intentions of some of Leonardo s most reverent admirers should have failed.

The #1 New York Times bestseller from Walter Isaacson brings Leonardo da Vinci to life in this exciting new biography that is “a study in creativity: how to define it, how to achieve it…Most important, it is a powerful story of an exhilarating mind and life” (The New Yorker). Based on thousands of pages from Leonardo da Vinci’s astonishing notebooks and new discoveries about his life and work, Walter Isaacson “deftly reveals an intimate Leonardo” (San Francisco Chronicle) in a narrative that connects his art to his science. He shows how Leonardo’s genius was based on skills we can improve in ourselves, such as passionate curiosity, careful observation, and an imagination so playful that it flirted with fantasy. He produced the two most famous paintings in history, The Last Supper and the Mona Lisa. With a passion that sometimes became obsessive, he pursued innovative studies of anatomy, fossils, birds, the heart, flying machines, botany, geology, and weaponry. He explored the math of optics, showed how light rays strike the cornea, and produced illusions of changing perspectives in The Last Supper. His ability to stand at the crossroads of the humanities and the sciences, made iconic by his drawing of Vitruvian Man, made him history’s most creative genius. In the “luminous” (Daily Beast) Leonardo da Vinci, Isaacson describes how Leonardo’s delight at combining diverse passions remains the ultimate recipe for creativity. So, too, does his ease at being a bit of a misfit: illegitimate, gay, vegetarian, left-handed, easily distracted, and at times heretical. His life should remind us of the importance to be imaginative and, like talented rebels in any era, to think different. Here, da Vinci “comes to life in all his remarkable brilliance and oddity in Walter Isaacson’s ambitious new biography…a vigorous, insightful portrait” (The Washington Post).

"For lovers of art history, this lavishly illustrated and well-written book is an absolute gem." – Italia! Magazine Leonardo da Vinci was the epitome of the Renaissance humanist ideal, a logical polymath of epic proportions who excelled and had interests not just in art but in invention, anatomy, architecture, engineering, literature, mathematics, music, science, astronomy and more. His oeuvre is astounding and he is rightly famed for his masterpieces of painting such as the Mona Lisa and The Last Supper, and his astonishingly technical and graceful drawings. The phenomenon that was Leonardo would not of course have flourished to such an extent had it not been for the patronage and sponsorship of the Medici family, who commissioned a large proportion of the art and architecture of the era and fostered a fertile climate for creativity. This sumptuous new book offers a broader view of this master artist in the context of this environment, alongside the work of other key artists who benefited from the Medicis, from Brunelleschi through Donatello to Michelangelo and Raphael.

How our image of the Renaissance’s most famous artist is a modern myth Leonardo da Vinci (1452–1519) never signed a painting, and none of his supposed self-portraits can be securely ascribed to his hand. He revealed next to nothing about his life in his extensive writings, yet countless pages have been written about him that assign him an identity: genius, entrepreneur, celebrity artist, outsider. Addressing the ethical stakes involved in studying past lives, Stephen J. Campbell shows how this invented Leonardo has invited speculation from figures ranging from art dealers and curators to scholars, scientists, and biographers, many of whom have filled in the gaps of what can be known of Leonardo’s life with claims to decode secrets, reveal mysteries of a vanished past, or discover lost masterpieces of spectacular value. In this original and provocative book, Campbell examines the strangeness of Leonardo’s words and works, and the distinctive premodern world of artisans and thinkers from which he emerged. Far from being a solitary genius living ahead of his time, Leonardo inhabited a vibrant network of artistic, technological, and literary exchange. By investigating the politics and cultural tensions of the era as well as the most recent scholarship on Leonardo’s contemporaries, workshop, and writings, Campbell places Leonardo back into the milieu that shaped him and was shaped by him. He shows that it is in the gaps and contradictions of what we know of Leonardo’s life that a less familiar and far more historically significant figure appears.
