Learning by Making

Sometimes the best form of education is synthetic. Reviewing precedents is one thing, but the best way to learn often involves taking a stab at something yourself. I often marveled, for example, at the way my former professor Michael Bell would not only study great architectural plans by the likes of Mies or Le Corbusier, but would actually redraw them many times himself. No doubt he gained more knowledge from this direct, haptic involvement with the works than by merely gazing at books or journals.

Harvard-based materials scientist Joanna Aizenberg is taking a similar approach to learning from nature. Fascinated with the marvels of engineering and beauty found in the delicate microstructures of sea sponges or sea urchins, Aizenberg seeks to gain clues related to how these organisms grow and respond to their local environment. Like Bell, Aizenberg is not content merely analyzing her subject matter visually (in this case, gazing through a microscope)—rather, she has actually assembled a variety of microstructures in an attempt to learn from her subject. Examples include “crystal blooms” comprised by the kind of bottom-up growth found in mollusk shells, “biological concrete” in a micro-grid of spongelike strands, and hydrophilic smart coatings that can change color with humidity. In the process, Aizenberg is not only building new materials, but also learning what makes biological building blocks tick.

His "Product of the Week" emails and three volumes of Transmaterial (2006, 2008, 2010) provide designers with a steady flow of inspiration—a 21st-century Grammar of Ornament. Blaine has practiced architecture in Japan and the U.S. and has been published in more than 40 design, business, and science publications. The recipient of a Fulbright fellowship for 2006–07, he researched contemporary Japanese material innovations at the Tokyo University of Science. He currently teaches architecture and co-directs the M.S. in Sustainable Design program at the University of Minnesota. His book Matter in the Floating World was published by Princeton Architectural Press in 2011.
