Curve Quotes - page 9
Let us develop a kind of dangerous unselfishness. One day a man came to Jesus; and he wanted to raise some questions about some vital matters in life. At points, he wanted to trick Jesus, and show him that he knew a little more than Jesus knew, and through this, throw him off base. Now that question could have easily ended up in a philosophical and theological debate. But Jesus immediately pulled that question from mid-air, and placed it on a dangerous curve between Jerusalem and Jericho. And he talked about a certain man, who fell among thieves. You remember that a Levite and a priest passed by on the other side. They didn't stop to help him. And finally a man of another race came by. He got down from his beast, decided not to be compassionate by proxy. But with him, administered first aid, and helped the man in need. Jesus ended up saying, this was the good man, because he had the capacity to project the "I" into the "thou," and to be concerned about his brother.

In his curious tract on Stereometry, published in 1615, Kepler made some advances in the doctrine of infinitesimals. Prompted to the task by a dispute with the seller of some casks of wine, he studied the measurement of solids formed by the revolution of a curve round any line whatever. In solving some of the simplest of these problems, he conceived a circle to be formed of an infinite number of triangles having all their vertices in the centre, and their infinitely small bases in the circumference of the circle, and by thus rendering familiar the idea of quantities infinitely great and infinitely small, he gave an impulse to this branch of mathematics. The failure of Kepler, too, in solving some of the more difficult of the problems which he himself proposed roused the attention of geometers, and seems particularly to have attracted the notice of Cavaleri.
