Famous quotes containing the words advanced and/or research:
“For such an advanced civilization as ours to be without images that are adequate to it is as serious a defect as being without memory.”
—Werner Herzog (b. 1942)
“The working woman may be quick to see any problems with children as her fault because she isn’t as available to them. However, the fact that she is employed is rarely central to the conflict. And overall, studies show, being employed doesn’t have negative effects on children; carefully done research consistently makes this clear.”
—Grace Baruch (20th century)
