Increase the donation

The crumbling, old church building needed remodeling, so the preacher made an impassioned appeal, looking directly at the richest may in town. At the end of the message, the rich man stood up and announced, "Pastor, I will contribute $1,000."

Just then, plaster fell from the ceiling and struck the rich man on the shoulder. He promptly stood again and shouted, "Pastor, I will increase my donation to $5,000."

Before he could sit back down, plaster fell on him again, and again he virtually screamed, "Pastor, I will double my last pledge."

He sat down, and an larger chunk of plaster fell hitting him on the head. He stood once more and hollered, "Pastor, I will give $20,000!"

This prompted a deacon to shout, "Hit him again, Lord! Hit him again!"

Argand diagram

In 1797, the concept of a geometrical interpretation of complex numbers was submitted by Caspar Wessel in a paper to a meeting of the Royal Danish Academy of Sciences.He represented complex numbers as points in a Cartesian plane, with the real portion of the number on the x axis and the imaginary part on the y axis. This was also independently devised a few years later, by Jean-Robert Argand, an amateur mathematician who self-published his ideas in an anomymous monograph(1806). Through publicity generated when Argand came forward and identified himself as the author, it was his name that has the lasting association with the Argand diagram.«
