Shapiro Delay
The Shapiro time delay effect, or gravitational time delay effect, is one of the four classic solar system tests of general relativity. Radar signals passing near a massive object take slightly longer to travel to a target and longer to return than they would if the mass of the object were not present.

“Lastly, his tomb
Shall list and founder in the troughs of grass
And none shall speak his name.”
—Karl Shapiro (b. 1913)
“To achieve the larger goal of teaching her children consideration of others, a mother can tolerate some frustration of her own wishes, she can delay having what she wants, she can be flexible enough to compromise. And this is exactly what her child must also learn: that it is possible to survive frustration, it is possible to wait for what he wants, it is possible to compromise without capitulating.”
—Elaine Heffner (20th century)
