Green's Functions For Solving Inhomogeneous Boundary Value Problems
The primary use of Green's functions in mathematics is to solve non-homogeneous boundary value problems. In modern theoretical physics, Green's functions are also usually used as propagators in Feynman diagrams (and the phrase Green's function is often used for any correlation function).

“There was an old man lived out in the wood,
His trade was a-cutting of Broom, green Broom;
He had but one son without thrift, without good,
Who lay in his bed till ‘twas noon, bright noon.”
—Unknown. Broom, Green Broom (l. 1–4)
“One of the most highly valued functions of used parents these days is to be the villains of their children’s lives, the people the child blames for any shortcomings or disappointments. But if your identity comes from your parents’ failings, then you remain forever a member of the child generation, stuck and unable to move on to an adulthood in which you identify yourself in terms of what you do, not what has been done to you.”
—Frank Pittman (20th century)
“More than a decade after our fellow citizens began bedding down on the sidewalks, their problems continue to seem so intractable that we have begun to do psychologically what government has been incapable of doing programmatically. We bring the numbers down—not by solving the problem, but by deciding it’s their own damn fault.”
—Anna Quindlen (b. 1952)
“No man has a right to fix the boundary of the march of a nation; no man has a right to say to his country, “Thus far shalt thou go and no further.””
—Charles Stewart Parnell (1846–1891)
