Once upon a time there was a shepherd looking after his sheep on the edge of a desert road. Suddenly a brand new Jeep Cherokee screeches to a halt next to him. The driver a young, a man dressed in a Brioni suit, Ceruti shoes, Ray-Ban sunglasses and a YSL tie, gets out and asks the shepherd, "If I guess how many sheep you have, would you give me one of them?"
The shepherd looks at the young man, then looks at the sheep, "All right."
The young man parks the car, connects his notebook to his cell phone, enters a NASA site, scans the ground using his GPS, opens a database and 60 Excel tables filled with algorithms, then prints out a 150-page report on his high-tech mini-printer.
"You have exactly 1,586 sheep," he declares.
"That's correct," says the shepherd. "You may take the sheep."
The young man takes the sheep and puts it in the back of his car.
The shepherd asks, "If I guess your profession, will you return my sheep?"
"Why not?" answers the young man.
"You're a Consultant," declares the shepherd confidently.
"That's amazing! How did you guess so quickly and easily?" asks the man.
"Very simple," replies the shepherd. "First you came here without being called. Secondly, you charge me to tell me something I already knew. And thirdly, you do not understand anything about what I do. And lastly you took my sheepdog..."

First dated printed arithmetic book

In 1478, the anonymous Arte dell'Abbaco(“The Art of the Abacus”), printed in Treviso, Italy had this publication date. It is the first dated printed book on arithmetic. The unknown author was likely a priest, and it was dedicated to some of his young friends who kept asking for it. The printer was probably Geradus de Lisa, dé Flandria. The 124-page text dealt with commercial applications of arithmetic, so the language was the local vernacular Venetian dialect, not the scholarly Latin used for the abstract studies of universities. The book teaches the four main operations, with numerous examples, and the concept of fractions (but not the as yet unknown decimals). He shows how to calculate the date of the new Moon. Although some pamphlets on Algorithmus are possibly older than this book, they are undated.«[Image: detail of a calculation shown in the book.]
