The brightness of every room made his sensitive eyes squint.
The emerging brightness of the new day, while inviting, did nothing to sort out the tangle of thoughts crowding his brain like the line of a snarled fishing reel.
Stars whose brightness fluctuates are called variable stars.
I hope your Christmas Day will be a very happy one and that the New Year will be full of brightness and joy for you and every one.
He returned to the glaring brightness of the condo.
She blinked back the flood of brightness and covered her eyes as she slumped back on the sofa.
353), with which he measured the relative brightness of 2784 stars between the North Pole and about - so declination.
Such a brightness on the face like the light of heaven, and from the blessed Mother's cheek it drops and drops....
There, standing silhouetted in the brightness behind him stood the pride of the FBI, Jonathan Winston.
" Thus the magnitude of the central spot is diminished, and the brightness of the rings increased, by covering the central parts of the object-glass."
Of course, he soon noticed the brightness of the leaves, and discovered the cause, too, when he caught sight of the broken jars and vases from which the melted treasure was still dropping.
He cast his eyes downward, away from the brightness, and saw little except the ground in front of him.
The sun knows that you like to see the world covered with beautiful white snow and so he kept back all his brightness, and let the little crystals form in the sky.
Perhaps the best data for a comparison are those afforded by the varying brightness of stars at different altitudes.
Of course, he had not gone far when he noticed the brightness of the leaves, and he quickly guessed the cause when he saw the broken jars from which the treasure was still dropping.
His fine eyes lit up with a thoughtful, kindly, and unaccustomed brightness, but he was looking not at his sister but over her head toward the darkness of the open doorway.
Vii., where wisdom, the brightness of the everlasting light, is the source of all that is noblest in human life.
Red lead or triplumbic tetroxide, Pb304, is a scarlet crystalline powder of specific gravity 8.6-9.1, obtained by roasting very finely divided pure massicot or lead carbonate; the brightness of the colour depends in a great measure on the roasting.
" As the little water-drop poured into a large measure of wine seems to lose its own nature entirely and to take on both the taste and the colour of the wine; or as iron heated red-hot loses its own appearance and glows like fire; or as air filled with sunlight is transformed into the same brightness so that it does not so much appear to be illuminated as to be itself light - so must all human feeling towards the Holy One be self-dissolved in unspeakable wise, and wholly transfused into the will of God.
In the Avesta, after the separation of the Iranian stock from the Hindu and the rise of Zoroastrianism, which elevated Ormazd to the summit of the Persian theological system, his role was more distinct, though less important; between Ormazd, who reigned in eternal brightness, and Ahriman, whose realm was eternal darkness, he occupied an intermediate position as the greatest of the yazatas, beings created by Ormazd to aid in the destruction of evil and the administration of the world.
When light proceeding from a small source falls upon an opaque object, a shadow is cast upon a screen situated behind the obstacle, and this shadow is found to be bordered by alternations of brightness and darkness, known as " diffraction bands."
An interesting exception to the general rule that full brightness requires the existence of the first zone occurs when the obstacle assumes the form of a small circular disk parallel to the plane of the incident waves.
Within the rectangle formed by pairs of consecutive dark lines, and not far from its centre, the brightness rises to a maximum; but these subsequent maxima are in all cases much inferior to the brightness at the centre of the entire pattern (=o, n =o).
If the aperture be increased, not only is the total brightness over the focal plane increased with it, but there is also a concentration of the diffraction pattern.
So long as there is no sensible discrepancy of phase there can be no sensible diminution of brightness as compared with that to be found at the focal point itself.
We may compare the brightness with that in the direction 0=0.
Or -2/37r:1; so that the brightness in this direction is 4/91r 2 of the maximum at 0=0.
Let us now consider the distribution of brightness in the image of a double line whose components are of equal strength, and at such an angular interval that the central line in the image of one coincides with the first zero of brightness in the image of the other.
3 the curve of brightness for one component is ABC, and for the other OA'C'; and the curve representing half the combined brightnesses is E'BE.
The brightness (corresponding to B) midway between the two central points AA' is 8106 of the brightness at the central points themselves.
If the angular interval between the components of a double line be half as great again as that supposed in the figure, the brightness midway between is 1802 as against 1.0450 at the central lines of each image.
Notwithstanding this difference in the brightness of the objects, we were able with this reflecting telescope to see whatever we have hitherto discovered with the Huygenian, particularly the transits of Jupiter's satellites and their shadows over his disk, the black list in Saturn's ring, and the edge of his shadow cast on his ring.
This scene has all the happy brightness of the early Galilean ministry which St Mark records.
The halo diminishes in brightness from the centre outwards, and is probably due to the diffraction of light.
The extent to which it renders aurora invisible depends, however, so much on the natural brightness of the aurora - which depends on the time and the place - and on the sharpness of the outlook kept, that it is difficult to gauge it.
In auroral displays the brightness often varies greatly over the illuminated area and changes rapidly.
At Jan Mayen (8) in 1882-1883 a scale was employed running from 1, taken as corresponding to the brightness of the milky way, to 4, corresponding to full moonlight.
When dressed and dyed they should have regular, close and bright curl, varying from a small to a very large one, and if of equal size, regularity, tightness and brightness, the value is comparatively a matter of fancy.
It is much shorter than the typical instruments described, so that the maximum brightness of image is obtained.
But its brightness was far from comparing with the glorious accounts of its former apparitions.
That this should have been due to the process of dissipation does not seem possible in so short a period; we must therefore consider either that the earlier accounts are greatly exaggerated, or that the brightness of the comet is subject to changes from some unknown cause.
With the first instrument of this kind, having objectives of 1 5 inch aperture, he measured the brightness of 4260 stars, including all stars down to the 6th magnitude between the North Pole and - 30° declination.
