{ "item_title" : "The Physical Life of AI", "item_author" : [" Adrian Keller "], "item_description" : "AI can feel weightless. A prompt goes in. Words, images, or decisions come out. But underneath that smooth experience is a physical world of silicon, memory, wiring, packaging, power, cooling, and data movement. In The Physical Life of AI, Adrian Keller gives readers a clear, approachable guide to the hardware reality behind modern AI. The book follows how information is represented, moved, transformed, and preserved across transistors, memory systems, GPUs, data centers, and edge devices. Along the way, readers learn why distance is expensive, why precision can be negotiable, why power becomes heat, and why the whole system matters more than any single chip. The book connects semiconductor physics, memory hierarchy, AI accelerators, high-bandwidth memory, packaging, networking, cooling, edge AI, photonics, analog computing, and emerging hardware without assuming an engineering background. Whether you are a student, educator, scientist, engineer, founder, or simply a curious reader, The Physical Life of AI helps you see AI not as magic, but as a physical process with real costs, real constraints, and real design trade-offs.", "item_img_path" : "https://covers3.booksamillion.com/covers/bam/9/79/817/874/9798178745830_b.jpg", "price_data" : { "retail_price" : "14.99", "online_price" : "14.99", "our_price" : "14.99", "club_price" : "14.99", "savings_pct" : "0", "savings_amt" : "0.00", "club_savings_pct" : "0", "club_savings_amt" : "0.00", "discount_pct" : "10", "store_price" : "" } }
