But why "t-minus"?  What is the signifigance of the "t"?  I can only assume "time minus"?67.184.135.180 01:46, 30 December 2006 (UTC)
thread_title:  Music 

message: Does anyone know why it is 'T minus'? does the T stand for 'time', and if so, what sense does that make? like say i am doing something in 5:00 minutes. one second passes, then I am doing it in T minus 5 minutes and 59 seconds. so i am doing it one second from now? i don't get it. please explain! —Preceding unsigned comment added by 69.181.198.10 (talk • contribs) 09:07, 7 August 2007
No, you are doing it at T.  Say the launch time is 5 minutes from now, then now is T minus 5 minutes; one second later is T minus 4 minutes 59 seconds. -- Smjg 10:15, 7 August 2007 (UTC)
thread_title:  Question 

message: We really need an authoritative explanation of the origin of the T in T-Minus:
*#Did it originally have to do with rocketry or something else?
*#Who came up with it and used it where & when?
*#Was T definitely Time or might it have been Takeoff, Terminus, Termination, Triumph, Teatime, or some foreign word or esoteric term?
*#And how do we know?
Also: Is there a Wiktionary definition of T-Minus?  NO!
Why not?  It's a WikiWide conspiracy it is!

thread_title:  Meaning & History of "T" in T-Minus 

message: Should countdown in this sense not be two words (With or without a hyphen)? I've just checked the OED which has it as one word but would count-down and count down be acceptable alternatives and if yes should it be mentioed in the opening?(Morcus (talk) 00:51, 20 May 2008 (UTC)

thread_title:  Controversy 

message: This is just a hypothesis of mine, but as a mathematics graduate, I've always suspected that the "T-minus" construct, or more specifically just the "minus" part of it (the "T" presumably standing for either "Test" or "Time" as indicated in the article's introduction) may have been derived from, or at least been influenced by the Heaviside step function. The Wikipedia page doesn't currently support the definition I seem to recall learning, but nonetheless I think it's just as valid a definition as any. Simply: H(t-x) = {0 where t<x and 1 where t>=x}. The function acts as a mathematical representation of a switch whose product with any other function zeroes out for premature time periods, and flips on to take the value of said function once adequate time has elapsed. I hope this helps, but alas, I have so source to back this up. :( 71.236.136.184 (talk) 06:24, 14 September 2013 (UTC)
thread_title:  Regarding The "Minus" 

message: The introduction to the article currently contains the sentence "When counting down for a holiday it is illegal to start before 10 weeks." I assume that was someone's attempt at humour? Perhaps someone could be so kind and delete that?
