The Physics of Information Technology [Hardcover]

A companion volume to the best-selling The Nature of Mathematical Modeling from the same author.In this companion volume to his highly-successful The Nature of Mathematical Modeling, Gershenfeld explores the devices we use to collect, transform, transmit, and interact with electronic information. He looks at devices including hard disk drives, GPS receivers and VLSI circuits. Attention is drawn throughout to the opportunities associated with closely integrating physical and logical descriptions of classical and quantum information. This self-contained volume will be ideal for both physical scientists, engineers and computer scientists.In this companion volume to his highly-successful The Nature of Mathematical Modeling, Gershenfeld explores the devices we use to collect, transform, transmit, and interact with electronic information.

This self-contained volume will be ideal for both physical scientists, engineers and computer scientists.The Physics of Information Technology explores the familiar devices that we use to collect, transform, transmit, and interact with electronic information. Many such devices operate surprisingly close to very many fundamental physical limits. Understanding how such devices work, and how they can (and cannot) be improved, requires deep insight into the character of physical law as well as engineering practice. The book starts with an introduction to units, forces, and the probabilistic foundations of noise and signaling, then progresses through the electromagnetics of wired and wireless communications, and the quantum mechanics of electronic, optical, and magnetic materials, to discussions of mechanisms for computation, storage, sensing, and display.
