Bone surgeons joined the radius (larger of the two forearm bones) with a narrow metal plate held in place by two screws driven through each end into the bone. The smaller bone was left to rejoin itself. Vascular surgeons joined the major blood vessels, not by stitching, which even the traditionally patient Chinese admit is difficult, but by turning one end up into a cuff over a tiny plastic ring and pulling the other end over the slight bulge...
...doom that Ortega y Gasset felt when he shuddered about "mass man." Yet, sheer numbers are an overwhelming factor in the individual's existence. Demographers calculate that, given a U.S. population density of ten people per square mile in the mid-19th century, each American inside a ten-mile radius could "interact" with about 3,000 others. But the density in the U.S. today is 60 people per square mile, making possible interaction with nearly 20,000 (in cities the figure rises into the millions...
Lemon Shape. The sphere itself must be machined with incredible accuracy: no more than five millionths of an inch of error can be tolerated. When it is not spinning, the sphere is not exactly spherical; it is slightly prolate (lemon-shaped), with its equatorial radius (where the metal is thickest) .000226 in. shorter than the polar radius. When it is spinning at 30,000 r.p.m., though, centrifugal force makes the equator bulge just enough to form a perfect sphere...
...above chart indicates the radius (in miles) of the area of 100% mortality, with or without fallout shelters. For example, if a 10 megaton bomb burst over the Harvard Yard, Concord would be within the area completely destroyed...
Most graduates of seminars have felt their seminars effective in accomplishing the aims of general education as defined by the Red Book, only when the seminar explicitly undertook broad questions or had what the report calls "centrifugalness"--the seminar "begins in a small radius and as it accelerates encompasses an ever-expanding field. But there have been seminars, and seminars, and seminars, that have lacked both breadth and "centrifugalness." As the proportion of seminar leaders drawn from the junior faculty increases, there is little reason to suppose that the proportion of narrow seminars will decrease. To save the freshman...
