Book Reviews
We review two recently published books: One tracks the relationship between the practice of medicine and architecture from ancient times to the present, while the other discusses the urgent need to reinvent medical facilities so they are better for patients and the environment.

Behind SANAA’s illusion of weightlessness
Now that the New Museum on Manhattan’s Lower East Side is complete, and its structure enclosed, there is little evidence of the system that supports the seven-story building that seems to be made up of nothing heavier than precariously stacked cardboard boxes.

Chuck Hoberman wants buildings to change
Chuck Hoberman has a vision of Buckminster Fuller. As the New York–based artist, mechanical engineer, and product designer expands his projects to large-scale architecture, he is integrating his mechanized elements to develop a new strain of sustainable and flexible structures that conceptually relate to what the late Fuller had imagined, but never realized, decades before.
