Famous quotes containing the words probe and/or effect:
“Y’know scientists are funny. We probe and measure and dissect. Invent lights without heat, weigh a caterpillar’s eyebrow. But when it comes to really important things we’re as stupid as the caveman.... Like love. Makes the world go ‘round, but what do we know about it? Is it a fact? Is it chemistry? Electricity?”
—Martin Berkeley, and Jack Arnold. Helen Dobson (Lori Nelson)
“I would define the poetic effect as the capacity that a text displays for continuing to generate different readings, without ever being completely consumed.”
—Umberto Eco (b. 1932)
