Eletrical power? Weight-loss and the secret to preventing aging? Can we get a biologist to fact-check this?

First sentence wording

The end of the first sentence makes no sense, what's it mean? "...part or process." Dougher 19:19, 17 June 2007 (UTC)

Log form

Firstly, this is totally superfluous. It does not elucidate the article in any way; a log form is just something used in practical application, and diminishingly rarely with modern calculators.

Secondly, it is wrong. The formula given is not even a good approximation.

For this reason I am going to remove it again, and next time, before reverting justified edits with no explanation, discuss it here. --81.157.72.68 (talk) 04:31, 16 September 2011 (UTC)

The log form is both correct and is frequently used in the field of biomechanics.  Any further removal wthout exceptional justification here will be considered vandalism. Mokele 17:06, 17 September 2011 (UTC)

I don't care what you 'consider' it, your threatening demeanor is totally inappropriate. :/

The correct log form of y = kx^a is logy = alogx + logk. This is an objective fact and a basic mathematical deduction. You will also find this form in the relevant Wikipedia article (but not yours). Additionally the current notation is ambiguous; ~ can either mean approximately equal to or asymptotic to. The first is completely incorrect, and the second is not relevant; the law is only relevant for a finite range and logk can be arbitrarily important for this range. If you can cite some source that explains why asymptotes are the only thing of relevance for allometry, then you can change it. Until then, as you are so averse to its removal, I will write it in a form that is both accurate, and also more generally applicable (trivially encompassing the asymptotic form). --81.157.72.68 (talk) 21:51, 18 September 2011 (UTC)

This is another user - and mathematician. The axes labels of the figure of vol vs length are absolutely incorrect. They should be logs on both axes. Too bad, I was going to use this page as a reference for my course. This, and the fuzzyness in text about log or no log (and clearly the lack of agrement on something that should be very basic) makes my using it as a reference impossible. The first time I see such an obvious mistake in Wikipedia! — Preceding unsigned comment added by 71.232.148.29 (talk) 20:26, 20 April 2012 (UTC)

So go fix it, then. HCA (talk) 14:29, 21 April 2012 (UTC)

Allometry in characteristics of a city

I read somewhere that city infrastuctures (like transportation) follow a power law with an exponent greater than one. So a city double the size needs more than double transportation budget, etc...

Urban Scaling properties? Allometric scaling in networks? What is the exponent? Any reference?

the volume of roads in a city which happen to grow in the opposite fashion (sublinearly).
