2430 A.D.

2430 A.D. is a science fiction short story by Isaac Asimov. It first appeared in the October 1970 issue of Think, the IBM house magazine, and was reprinted in Asimov's 1975 collection Buy Jupiter and Other Stories.

Early in 1970 the author was commissioned by Think to write a story based on a quotation by writer and social commentator J. B. Priestley:

Asimov, assuming that Think wanted a story that illustrated Priestley's quotation, crafted 2430 A.D. He selected the date because he calculated that at the then-current rate of human population growth, doubling every thirty-five years, that would be the year when the world's animal biomass would consist entirely of human beings. Asimov wrote the story on April 26, 1970 but it was rejected as Think had actually wanted a story that refuted the quotation. ("Well, they never said so," Asimov remarked later.) After Asimov wrote a second story that did refute the quotation, Think took the first story after all and published it in their October 1970 issue. The second story was later published in Analog magazine as The Greatest Asset. Both stories inspired by the Priestley quote were included in the 1975 collection Buy Jupiter and Other Stories.

0 (year)

Year zero does not exist in the Anno Domini (or Common Era) system usually used to number years in the Gregorian calendar and in its predecessor, the Julian calendar. In this system, the year 1 BC is followed by AD 1. However, there is a year zero in astronomical year numbering (where it coincides with the Julian year 1 BC) and in ISO 8601:2004 (where it coincides with the Gregorian year 1 BC) as well as in all Buddhist and Hindu calendars.

Historians

The Anno Domini era was introduced in 525 by Scythian monk Dionysius Exiguus (c. 470–c. 544), who used it to identify the years on his Easter table. He introduced the new era to avoid using the Diocletian era, based on the accession of Roman Emperor Diocletian, as he did not wish to continue the memory of a persecutor of Christians. In the preface to his Easter table, Dionysius stated that the "present year" was "the consulship of Probus Junior [Flavius Anicius Probus Iunior]" which was also 525 years "since the incarnation of our Lord Jesus Christ". How he arrived at that number is unknown.

1988

1988 (MCMLXXXVIII) was a leap year starting on Friday (dominical letter CB) of the Gregorian calendar, the 1988th year of the Common Era (CE) and Anno Domini (AD) designations, the 988th year of the 2nd millennium, the 88th year of the 20th century, and the 9th year of the 1980s decade.

In the 20th century, the year 1988 has the most Roman numeral digits (11).

1988 was a crucial year in the early history of the Internet—it was the year of the first well-known computer virus, the 1988 Internet worm. The first permanent intercontinental Internet link was made between the United States (NSFNET) and Europe (Nordunet) as well as the first Internet-based chat protocol, Internet Relay Chat. The concept of the World Wide Web was first discussed at CERN in 1988.

The Soviet Union began its major restructuring towards a mixed economy at the beginning of 1988 and began its gradual collapse. The first extrasolar planet, Gamma Cephei Ab (confirmed in 2002) was detected this year and the World Health Organization began its mission to eradicate polio, a feat that is nearly complete as of 2015.

Forfeda

The Forfeda are the "additional" letters of the Ogham alphabet, beyond the basic inventory of twenty signs. The most important of these are five forfeda which were arranged in their own aicme or class, and were invented in the Old Irish period, several centuries after the peak of Ogham usage. They appear to have represented sounds felt to be missing from the original alphabet, maybe é(o), ó(i), ú(i), p and ch.

The aicme forfeda

The five aicme forfeda are glossed in the manuscripts Auraicept na n-Éces ('The Scholars' Primer), De dúilib feda ('Elements of the Letters') and In Lebor Ogaim ('The Book of Ogam'), by several Bríatharogaim ("word oghams" ), or two word kennings, which explain the meanings of the names of the letters of the Ogham alphabet. Three variant lists of bríatharogaim or 'word-oghams' have been preserved, dating to the Old Irish period. They are as follows:

Later Medieval scholars believed that all of the letter names of the ogham alphabet were those of trees, and attempted to explain the bríatharogaim in that light. However, modern scholarship has shown that only eight at most of the original twenty letter names are those of trees, and that the word-oghams or kennings themselves support this. Of the forfeda letter names, only one may be that of a tree or shrub (pín) and their kennings as edited (in normalized Old Irish) and translated by McManus (1988) are as follows:
