Physical Tree Topology

Famous quotes containing the words physical and/or tree:

“I have no purpose to introduce political and social equality between the white and black races. There is a physical difference between the two, which, in my judgement, will probably for ever forbid their living together upon the footing of perfect equality; and inasmuch as it becomes a necessity that there must be a difference, I ... am in favour of the race to which I belong having the superior position.”
—Abraham Lincoln (1809–1865)

“The wind flapped loose, the wind was still,
Shaken out dead from tree and hill:
I had walked on at the wind’s will,—
I sat now, for the wind was still.”
—Dante Gabriel Rossetti (1828–1882)
