Gravity probe falters

Newtonian Gravity Predictions For Gravity Probe B

Newtonian gravity and special relativity combine to produce a gravitomagnetic precession of an orbiting gyroscope that is one fourth as large as predicted by General Relativity. The geodetic effect is the same in both cases.

Where the Tagger Falters

Statistical n-gram taggers like that of [Church 1988] or [Foster 1991] assign a part-ofspeech label to each word in a text on the basis of probability estimates that are automatically derived from a large, already tagged training corpus. This paper examines the grammatical constructions which cause such taggers to falter most frequently. As one would expect, certain of these errors are due to l...

Viewpoint Finally , results from Gravity Probe B

The great blues singer Etta James’ signature song begins, “At laaasst, my love has come along . . . .” This may have been the feeling on May 4th when NASA announced the long-awaited results of Gravity Probe B [1], which are appearing now in Physical Review Letters[2]. Over 47 years and 750 million dollars in the making, Gravity Probe B was an orbiting physics experiment, designed to test two fu...

Reisenberger, et al., “A Possible Rescue of General Relativity in Di Herculis,” Astronomical Journal 97, pp. 216-221, 1989. Abstract: The binary DI Her has attracted attention because its low observed rate of apsidal advance, dw/dt = 1.0° ± 0.3°/100yr, appears to contradict general relativity, which see...
