Instant edit

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)Reply
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)Reply
Would that not be called an "instance" rather than an "instant"? JRSpriggs (talk) 05:39, 26 March 2011 (UTC)Reply
Not according to wiktionary wikt:instance / wikt: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)Reply

source for definition? edit

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

Mutually exclusive with what? edit

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)Reply
