The discovery of the aberration of light in 1725, due to James Bradley, is one of the most important in the whole domain of astronomy.
She is normally calm and level headed, so this outburst is an aberration.
We considered our defeat to be an aberration, since we'd easily beaten this team last season.
The residents considered the recent surge in burglaries to be an aberration, since their neighborhood was known for its safety.
The chromatic aberration of the object-glass of one of these telescopes is corrected for photographic rays, and the image formed by it is received on a highly sensitive photographic plate.
The swing to the right in the voter survey were considered to be a short-term aberration and of no consequence to the election.
The aberration is here unsymmetrical, the wave being in advance of its proper place in one half of the aperture, but behind in the other half.
When parallel rays fall directly upon a spherical mirror the longitudinal aberration is only about one-eighth as great as for the most favourably shaped single lens of equal focal length and aperture.
Both the aberration of axis points, and the deviation from the sine condition, rapidly increase in most (uncorrected) systems with the aperture.
The indirect method is based upon the observed constant of aberration or the displacement of the stars due to the earth's motion.
It has been in the past a source of much perplexity to observers of transits, but is now understood to be a result of irradiation, produced by the atmosphere or by the aberration of the telescope.
Hence for the rain to centrally traverse the tube, this must be inclined at an angle BAD to the vertical; this angle is conveniently termed the aberration due to these two motions.
Bradley recognized the fact that the experimental determination of the aberration constant gave the ratio of the velocities of light and of the earth; hence, if the velocity of the earth be known, the velocity of light is determined.
Assured that his explanation was true, Bradley corrected his observations for aberration, but he found that there still remained a residuum which was evidently not a parallax, for it did not exhibit an annual cycle.
