Problem: CHAPTER XXVII

Philippa and Helen looked at one another a little dolefully across the luncheon table.

"I supposes one misses the child," Helen said.

"I feel too depressed for words," Philippa admitted.

"A few days ago," Helen reminded her companion, "we were getting all the excitement that was good for any one."

"And a little more," Philippa agreed. "I don't know why things seem so flat now. We really ought to be glad that nothing terrible has happened."

"What with Henry and Mr. Lessingham both away," Helen continued, "and Captain Griffiths not coming near the place, we really have reverted to the normal, haven't we? I wonder--if Mr. Lessingham has gone back."

"I do not think so," Philippa murmured.

Helen frowned slightly.

"Personally," she said, with some emphasis, "I hope that he has."

"If we are considering the personal point of view only," Philippa retorted, "I hope that he has not."

Helen looked her disapproval.

"I should have thought that you had had enough playing with fire," she observed.

"One never has until one has burned one's fingers," Philippa sighed. "I know perfectly well what is the matter with you," she continued severely. "You are fretting because curried chicken is Dick's favourite dish."

"I am not such a baby," Helen protested. "All the same, it does make one think. I wonder--"

"I know exactly what you were going to say," Philippa interrupted. "You were going to say that you wondered whether Mr. Lessingham would keep his promise."

"Whether he would be able to," Helen corrected. "It does seem so impossible, doesn't it?"

Problem: The Z notation is a formal specification language used for describing and modelling computing systems. It is targeted at the clear specification of computer programs and computer-based systems in general.

In 1974, Jean-Raymond Abrial published "Data Semantics". He used a notation that would later be taught in the University of Grenoble until the end of the 1980s. While at EDF (Electricite de France), Abrial wrote internal notes on Z. The Z notation is used in the 1980 book "Methodes de programmation".

Z was originally proposed by Abrial in 1977 with the help of Steve Schuman and Bertrand Meyer. It was developed further at the Programming Research Group at Oxford University, where Abrial worked in the early 1980s, having arrived at Oxford in September 1979.

Abrial has said that Z is so named "Because it is the ultimate language!" although the name "Zermelo" is also associated with the Z notation through its use of ZermeloFraenkel set theory.

Z is based on the standard mathematical notation used in axiomatic set theory, lambda calculus, and first-order predicate logic. All expressions in Z notation are typed, thereby avoiding some of the paradoxes of naive set theory. Z contains a standardized catalogue (called the "mathematical toolkit") of commonly used mathematical functions and predicates, defined using Z itself.

Problem: Billy had a pet turtle that he took good care of, everyday. His turtle's name was Tumble. Tumble liked to walk around outside in the garden and dig small holes to sleep in. Billy loved Tumble and would visit him outside when he got home from school. Tumble's favorite food was oatmeal. So, every day after school, Billy would make Tumble a big bowl of oatmeal and take it outside for Tumble to enjoy. Tumble would see Billy and walk up to him as fast as a turtle can go. Billy would put the bowl down and wait for Tumble to come up to the bowl to eat from it. When Tumble reached the bowl, he put his nose on it. But, the oatmeal was too hot to eat. Billy reached down and blew on the hot oatmeal, to cool it down for Tumble to eat. Once the oatmeal was cool enough, Tumble could dig in and eat his big bowl of oatmeal. Billy loved to watch as Tumble ate his bowl of oatmeal, because Billy took good care of Tumble, everyday.

Problem: Washington, D.C., formally the District of Columbia and commonly referred to as "Washington", "the District", or simply "D.C.", is the capital of the United States.

The signing of the Residence Act on July 16, 1790, approved the creation of a capital district located along the Potomac River on the country's East Coast. The U.S. Constitution provided for a federal district under the exclusive jurisdiction of the Congress and the District is therefore not a part of any state. The states of Maryland and Virginia each donated land to form the federal district, which included the pre-existing settlements of Georgetown and Alexandria. Named in honor of President George Washington, the City of Washington was founded in 1791 to serve as the new national capital. In 1846, Congress returned the land originally ceded by Virginia; in 1871, it created a single municipal government for the remaining portion of the District.

Washington had an estimated population of 681,170 as of July 2016. Commuters from the surrounding Maryland and Virginia suburbs raise the city's population to more than onemillion during the workweek. The Washington metropolitan area, of which the District is the principal city, has a population of over 6million, the sixth-largest metropolitan statistical area in the country.
