Famous quotes containing the words chemistry, biological and/or activities:
“The chemistry of dissatisfaction is as the chemistry of some marvelously potent tar. In it are the building stones of explosives, stimulants, poisons, opiates, perfumes and stenches.”
—Eric Hoffer (1902–1983)
“In America every woman has her set of girl-friends; some are cousins, the rest are gained at school. These form a permanent committee who sit on each other’s affairs, who “come out” together, marry and divorce together, and who end as those groups of bustling, heartless well-informed club-women who govern society. Against them the Couple of Ehepaar is helpless and Man in their eyes but a biological interlude.”
—Cyril Connolly (1903–1974)
“I am admonished in many ways that time is pushing me inexorably along. I am approaching the threshold of age; in 1977 I shall be 142. This is no time to be flitting about the earth. I must cease from the activities proper to youth and begin to take on the dignities and gravities and inertia proper to that season of honorable senility which is on its way.”
—Mark Twain [Samuel Langhorne Clemens] (1835–1910)
