Famous quotes containing the words compound and/or leaf:
“Give a scientist a problem and he will probably provide a solution; historians and sociologists, by contrast, can offer only opinions. Ask a dozen chemists the composition of an organic compound such as methane, and within a short time all twelve will have come up with the same solution of CH4. Ask, however, a dozen economists or sociologists to provide policies to reduce unemployment or the level of crime and twelve widely differing opinions are likely to be offered.”
—Derek Gjertsen, British scientist, author. Science and Philosophy: Past and Present, ch. 3, Penguin (1989)
“A leaf that is supposed to grow is full of wrinkles and creases before it develops; if one doesn’t have the patience and wants the leaf to be as smooth as a willow leaf from the start, then there is a problem.”
—Johann Wolfgang Von Goethe (1749–1832)
