Analogous and Digital


Book Description

Otl Aicher (1922-1991) was an outstanding personality in modern design, he was a co-founder of the legendary Hochschule fur Gestaltung (HfG), the Ulm School of Design, Germany. His works since the fifties of the last century in the field of corporate design and his pictograms for the 1972 Summer Olympics in Munich are major achievements in the visual communication of our times. "An integral component of Aicher's work is that it is anchored in a "philosophy of making" inspired by such thinkers as Ockham, Kant or Wittgenstein, a philosophy concerned with the prerequisites and aims, the objects and claims, of design. Aicher's complete theoretical and practical writings on design (which include all other aspects of visual creativity, such as architecture) are available with this new edition of the classic work. If Aicher prefers the analogous and concrete to the digital and abstract he does it with a philosophical intention. He relativizes the role of pure reason. He criticizes the rationality of Modernism as a result of the dominance of purely abstract thinking. Anyone who prefers the abstract to the concrete does not only misunderstand the mutual dependence of concept and view. In Aicher's judgement he is also creating a false hierarchy, a rank order that is culturally fatal. Things that are digital and abstract are not greater, higher and more important than things that are analogous and concrete." Wilhelm Vossenkuhl




The World as Design


Book Description

Otl Aicher's writings are explorations of the world, a substantive part of his work. In moving through the history of thought and design, building and construction, he assures us of the possibilities of arranging existence in a humane fashion. As ever he is concerned with the question of the conditions needed to produce a civilised culture. These conditions have to be fought for against apparent factual or material constraints and spiritual and intellectual substitutes on offer. Otl Aicher likes a dispute. For this reason, the volume contains polemical statements on cultural and political subjects as well as practical reports and historical exposition. He fights with productive obstinacy, above all for the renewal of Modernism, which he claims has largely exhausted itself in aesthetic visions; he insists the ordinary working day is still more important than the "cultural Sunday". Wolfgang Jean Stock




Foundations of Analog and Digital Electronic Circuits


Book Description

Unlike books currently on the market, this book attempts to satisfy two goals: combine circuits and electronics into a single, unified treatment, and establish a strong connection with the contemporary world of digital systems. It will introduce a new way of looking not only at the treatment of circuits, but also at the treatment of introductory coursework in engineering in general. Using the concept of ''abstraction,'' the book attempts to form a bridge between the world of physics and the world of large computer systems. In particular, it attempts to unify electrical engineering and computer science as the art of creating and exploiting successive abstractions to manage the complexity of building useful electrical systems. Computer systems are simply one type of electrical systems.+Balances circuits theory with practical digital electronics applications.+Illustrates concepts with real devices.+Supports the popular circuits and electronics course on the MIT OpenCourse Ware from which professionals worldwide study this new approach.+Written by two educators well known for their innovative teaching and research and their collaboration with industry.+Focuses on contemporary MOS technology.

The Spike


Book Description

The story of a neural impulse and what it reveals about how our brains work We see the last cookie in the box and think, can I take that? We reach a hand out. In the 2.1 seconds that this impulse travels through our brain, billions of neurons communicate with one another, sending blips of voltage through our sensory and motor regions. Neuroscientists call these blips “spikes.” Spikes enable us to do everything: talk, eat, run, see, plan, and decide. In The Spike, Mark Humphries takes readers on the epic journey of a spike through a single, brief reaction. In vivid language, Humphries tells the story of what happens in our brain, what we know about spikes, and what we still have left to understand about them. Drawing on decades of research in neuroscience, Humphries explores how spikes are born, how they are transmitted, and how they lead us to action. He dives into previously unanswered mysteries: Why are most neurons silent? What causes neurons to fire spikes spontaneously, without input from other neurons or the outside world? Why do most spikes fail to reach any destination? Humphries presents a new vision of the brain, one where fundamental computations are carried out by spontaneous spikes that predict what will happen in the world, helping us to perceive, decide, and react quickly enough for our survival. Traversing neuroscience’s expansive terrain, The Spike follows a single electrical response to illuminate how our extraordinary brains work.
