Help out with the To-do lists

Be consistent

Use a "standard" layout for transhumanism related articles (see: The perfect article, and Featured articles)
Add Transhumanism navigation template on the bottom of all transhumanism articles; (use {{Transhumanism}} or see navigation template)
Add Transhumanism info box to all transhumanism related talk pages (use {{Wpa}} or see info box)
Add [[Category:transhumanism]] to the bottom of all transhumanism related articles, so it shows up on the list of transhumanism articles

Maintenance / Etc

Find/cite sources for all positions of an article (see citing sources.
Try to expand stubs, however, some "new" articles may be neologisms, as this is common with positions on theories on life and may be suitable for deletion (see deletion process)
Watch the list of transhumanism related articles and add to accordingly (see transhumanism articles)
And always write for an encyclopedia.

This image is mathematically trivial, therefore cannot illustrate a "technological singularity" or anything of significance

This image caught my attention for its place in Transhumanism articles, namely for its axes titles. On the vertical axis is "time to next event" and the horizontal is "time to present". As a physicist, plotting two of the same variables against each other is a clear indication that something has gone wrong, and without suitable analysis can indicate that the graph could literally express any relationship one wants. This seems to be the case here.

It doesn't matter how we define an "event", or how far apart we space them in history. Given this assumption, the time between events can be expressed as $dt$ , but this can also be expressed as $dy$ since the "difference in time between events" is also the "time between events", so $dy=dt$ which can be solved as (ignoring integration constants) $y=t$ .

Now the trick is that the author plotted this on a log scale with $t=0$ representing the present. This effectively turns the new vertical axis $z=\log(y)=\log(t)$ , which is a singularity at $t=0$ . Therefore, if we plotted the graph simply linearly, it would be a trivially-obvious linear graph where the time between events becomes 0 at present. This graph therefore proves nothing except that the "time between events" is equal to the time between events.

I ask, given this information, that this graph be removed from all articles unless used as an example of triviality. SamuelRiv (talk) 21:58, 14 December 2008 (UTC)[reply]
