Reflector

Venus is referred to as the Evening Star because it is the brightest planet that can be viewed from Earth. Its thick cloud cover is an excellent reflector of the Sun's light.

That sticker is covering the reflector.

Apollo 11 astronauts set up the first reflector when they made the first manned flight to the moon nearly 40 years ago.

Then came a maid with hand-bag and shawls, and after her a tall young lady. She stood for a moment holding her skirt above the grimy steps,[…], and the light of the reflector fell full upon her.

Most reflectors on leadership are comfortable thinking of "ethical" and "unethical" as modifiers of leadership.

Nonreflectors simply thought through that which they already knew, reflectors evaluated experiences by interpreting these experiences, and critical reflectors re-evaluated their presuppositions to correct distortions in reasoning and attitudes.

The biography is an enormously powerful reflector of mainstream values: it is a statement that this person is someone, or did something, worth writing about. Similarly, because the biographer has access to myriads of details about her or his subject, what gets full exposure and what gets swept under the carpet can be more indicative of the biographer's values (and the society that instilled them) than of the actual subject's life.
