Discovery
The issue of the activity of nuclei of galaxies (AGN) was first raised by Soviet-Armenian physicist Prof. Victor Ambartsumian in the early 1950s. Although the idea concerning the activity of galactic nuclei for the first time was accepted very skeptically, after many years, as a result of the pressure of observations (the discovery of quasars, radio outbursts of galaxies, consequences of explosions in nuclei, ejection from nuclei, etc.) it did gain recognition. The concept of AGN now is widely accepted.

Famous quotes containing the word discovery:
“He is not a true man of science who does not bring some sympathy to his studies, and expect to learn something by behavior as well as by application. It is childish to rest in the discovery of mere coincidences, or of partial and extraneous laws. The study of geometry is a petty and idle exercise of the mind, if it is applied to no larger system than the starry one.”
—Henry David Thoreau (18171862)
“As the mother of a son, I do not accept that alienation from me is necessary for his discovery of himself. As a woman, I will not cooperate in demeaning womanly things so that he can be proud to be a man. I like to think the women in my sons future are counting on me.”
—Letty Cottin Pogrebin (20th century)
“The new supplants the old. Yet mens minds are stuffed with outworn bunk. Educating the young in the latest findings of authorities and scholars in the social sciences is important. It is equally important to devise ways and means for aiding the middle-aged and old to reexamine hang-over unscientific doctrines and ideas in the light of recent discovery and research.”
—Mary Barnett Gilson (1877?)
