The angle of inclination of the principal axis was found to have probable error of plus or minus 0.17 degrees both from analysis of the error of inertia measurement of the full-scale airplane and from tests with a model having a simple configuration. Analysis showed the probable error of the inertia measurements for the test airplane to be plus or minus1.00, plus or minus 0.49, and plus or minus 0.35 percent of the true moment of inertia about the X, Y, and Z body reference axes, respectively.
Alternate Worlds was first published in 1975 and became an instant classic, winning a Hugo award. This third edition brings the history of science fiction up to date, covering developments over the past forty years--a period that has seen the advent of technologies only imagined in the genre's Golden Age.
