Courage is sometimes frail as hope is frail: a fragile shoot between two stones that grows brave toward the sun though warmth and brightness fail, striving and faith the only strength it knows.
Frances Rodman

For both reasons, owing to the thermal motion and to the working together of various wavelengths, factors arise which, in a similar manner to the structural factor, exert some influence upon the brightness of the interference points but not upon their location.
Max von Laue

Happiness is a sunbeam which may pass through a thousand bosoms without losing a particle of its original ray; nay, when it strikes on a kindred heart, like the converged light on a mirror, it reflects itself with redoubled brightness. It is not perfected till it is shared.
Jane Porter

He that will enjoy the brightness of sunshine, must quit the coolness of the shade.
Samuel Johnson

My amateur interest in astronomy brought out the term 'magnitude,' which is used for the brightness of a star.
Charles Francis Richter

Sunshine is a welcome thing. It brings a lot of brightness.
Jimmie Davis

The world is full of poetry. The air is living with its spirit; and the waves dance to the music of its melodies, and sparkle in its brightness.
James Gates Percival

They who grasp the world, The Kingdom, and the power, and the glory, Must pay with deepest misery of spirit, Atoning unto God for a brief brightness.
Stephen Phillips

This dark brightness that falls from the stars.
Pierre Corneille

This is very similar to astronomy where different magnitudes are assigned to the brightness of an astronomical object, depending on the range of wavelengths being measured.
Charles Francis Richter

Well, again working strictly to the film, where you had this lovely, lovely land of brightness and color. And everybody is smiling and happy and butterflies flitting around and it was that kind of image that, it was like a dream world, really.
George Martin
