A porkchop plot (also pork-chop plot) is a chart that shows contours of equal characteristic energy (C₃) against combinations of launch date and arrival date for a particular interplanetary flight.

By examining the results of the porkchop plot, engineers can determine when launch opportunities exist (a launch window) that is compatible with the capabilities of a particular spacecraft. A given contour, called a porkchop curve, represents constant C₃, and the center of the porkchop the optimal minimum C₃. The orbital elements of the solution, where the fixed values are the departure date, the arrival date, and the length of the flight, were first solved mathematically in 1761 by Johann Heinrich Lambert, and the equation is generally known as Lambert's problem (or theorem).

"Justice delayed is justice denied" is a legal maxim. It means that if legal redress or equitable relief to an injured party is available, but is not forthcoming in a timely fashion, it is effectively the same as having no remedy at all.

This principle is the basis for the right to a speedy trial and similar rights which are meant to expedite the legal system, because of the unfairness for the injured party who sustained the injury having little hope for timely and effective remedy and resolution. The phrase has become a rallying cry for legal reformers who view courts, tribunals, judges, arbitrators, administrative law judges, commissions or governments as acting too slowly in resolving legal issues — either because the case is too complex, the existing system is too complex or overburdened, or because the issue or party in question lacks political favour. Individual cases may be affected by judicial hesitancy to make a decision. Statutes and court rules have tried to control the tendency; and judges may be subject to oversight and even discipline for persistent failures to decide matters timely, or accurately report their backlog. When a court takes a matter "under advisement" – awaiting the issue of a judicial opinion, order or judgement and forestalls final adjudication of a lawsuit or resolution of a motion – the issue of timeliness of the decision(s) comes into play.

Nicaraguan Sign Language (ISN; Spanish: Idioma de Señas de Nicaragua) is a sign language that was largely spontaneously developed by deaf children in a number of schools in western Nicaragua in the 1970s and 1980s. It is of particular interest to the linguists who study it because it offers a unique opportunity to study what they believe to be the birth of a new language.

Sprouts is a paper-and-pencil game that can be enjoyed simply by both adults and children. Yet it also can be analyzed for its significant mathematical properties. It was invented by mathematicians John Horton Conway and Michael S. Paterson at Cambridge University in the early 1960s. Setup is even simpler than the popular Dots and Boxes game, but game-play develops much more artistically and organically.

The bus service from London, England to Calcutta, India (now Kolkata) was considered to be the longest bus route in the world. The bus service, which started in 1957, was routed to India via Belgium, Yugoslavia and North Western India. This route is also known as the Hippie Route. According to reports, it took about 50 days for the bus to reach Calcutta from London. The voyage was over 10,000 miles (16,000 km) one way and 20,300 miles (32,700 km) for the round trip. It was in service until 1976. The cost of the trip one-way was £85 in 1957 and £145 in 1973. This amount included food, travel and accommodation.
