Countdown

A countdown is a sequence of backward counting to indicate the time remaining before an event is scheduled to occur. NASA commonly employs the term "T-minus" during the preparation for and anticipation of a rocket launch, and even "E-minus" for events that involve spacecraft that are already in space, where the "T" could stand for "Test" or "Time", and the "E" stands for "Encounter", as with a comet or some other space object. Other events for which countdowns are commonly used include the detonation of an explosive, the start of a race, the start of the New Year, or any anxiously anticipated event. An early use of a countdown once signaled the start of a Cambridge University rowing race. The first known association with rockets was in the 1929 German science fiction movie Die Frau im Mond (English: Woman in the Moon) written by Thea von Harbou and directed by Fritz Lang in an attempt to increase the drama of the launch sequence of the story's lunar-bound rocket.

Rocketry

A countdown is a carefully devised set of procedures ending with the ignition of a rocket's engine. Depending on the type of vehicle used, countdowns can start from 72 to 96 hours before launch time.

Macron

A macron (/ˈmækrɒn, ˈmeɪ-/) is a diacritical mark, a straight bar (¯) placed above a letter, usually a vowel. Its name derives from the Greek μακρόν (makrón), meaning "long", and was originally used to mark long or heavy syllables in Greco-Roman metrics. It now more often marks a long vowel. In the International Phonetic Alphabet, the macron is used to indicate a mid-tone; the sign for a long vowel is instead a modified triangular colon ⟨ː⟩.

The opposite is the breve ⟨˘⟩, which marks a short or light syllable or a short vowel.

Uses

Syllable weight

In Greco-Roman metrics and in the description of the metrics of other literatures, the macron was introduced and is still widely used to mark a long (heavy) syllable. Even relatively recent classical Greek and Latin dictionaries are still concerned with indicating only the length (weight) of syllables; that is why most still do not indicate the length of vowels in syllables that are otherwise metrically determined. Many textbooks about Ancient Rome and Greece use the macron even if it was not actually used at that time.

Bilabial trill

The bilabial trill is a type of consonantal sound, used in some spoken languages. The symbol in the International Phonetic Alphabet that represents this sound is ⟨ʙ⟩, and the equivalent X-SAMPA symbol is B\.

In many of the languages where the bilabial trill occurs, it only occurs as part of a prenasalized bilabial stop with trilled release, [mbʙ]. This developed historically from a prenasalized stop before a relatively high back vowel, such as [mbu]. In such instances, these sounds are usually still limited to the environment of a following [u]. However, the trills in Mangbetu may precede any vowel and are only sometimes preceded by a nasal.

A few languages, such as Mangbetu of Congo and Ninde of Vanuatu, have both a voiced and a voiceless bilabial trill.

There is also a very rare voiceless alveolar bilabially trilled affricate, [t̪͡ʙ̥] (written ⟨tᵖ̃⟩ in Everett & Kern) reported from Pirahã and from a few words in the Chapacuran languages Wari’ and Oro Win. The sound also appears as an allophone of the labialized voiceless alveolar stop /tʷ/ of Abkhaz and Ubykh, but in those languages it is more often realised by a doubly articulated stop [t͡p]. In the Chapacuran languages, [tʙ̥] is reported almost exclusively before rounded vowels such as [o] and [y].

Tau Sigma

Tau Sigma (ΤΣ) is an honor society for university transfer students.

Tau Sigma was established in 1999 at Auburn University. Part of the impetus for the creation of the organization was to provide a social support network to transfer students.

Specific membership criteria are established by individual chapters, however, in general a student must have transferred from one university to another university with one year worth of academic credits already earned and receive a 3.5 or better grade point average during the first term of enrollment at their new institution.

In addition to chapter-specific activities, the Tau Sigma national organization awards academic scholarships to Tau Sigma members. In 2013 it provided 105 scholarships totaling $36,500 in value. According to the organization, it had approximately 100 chapters in the United States as of 2014.
