Talk:Instant

Instant
Shouldn't this be an article? an "instant" is different from the "present". Instantaneous velocity at t=+12seconds is not the present velocity, if t<>+12 seconds

 * Even though "instant" is not a synonym of "present", if it is adequately explained in the article on present, then this redirect is sufficient. So you could just enhance that article.


 * The present is an instant. And what was the present at some time in the past was an instant. Similarly for the future. JRSpriggs (talk) 16:05, 23 March 2011 (UTC)
 * The present is an instant, but not all instants are the present, or have been, or will be. Many usages are theoretical, such as an instant on a function graph for a theoretical construct. 65.93.12.101 (talk) 02:10, 26 March 2011 (UTC)
 * Would that not be called an "instance" rather than an "instant"? JRSpriggs (talk) 05:39, 26 March 2011 (UTC)
 * Not according to wiktionary instance / instant ; the entire function graph would be an instance of a function graph, a point on the time-axis would be an instant. 65.93.12.101 (talk) 08:35, 26 March 2011 (UTC)

source for definition?
Do you have a source for the definition "An instant is a infinitesimal moment in time" ? Tkuvho (talk) 13:45, 31 March 2011 (UTC)

Mutually exclusive with what?
The usual phrasing would "A and B are mutually exclusive". "Instantaneous is, with respect to the measurement of time, mutually exclusive" doesn't make sense. Should that say "instantaneous and the measurement of time are mutually exclusive."? John G Hasler (talk) 00:14, 31 March 2024 (UTC)
