Beta or k
editAll of the fluvial geomorphologists I know use "k" instead of "/beta". I'm going to change this in the article; anyone who uses /beta please stop me. Awickert (talk) 23:49, 15 February 2009 (UTC)
- Also, incision rate is typically epsilon dot (with epsilon being erosion) instead of IR, changing this as well. Awickert (talk) 23:50, 15 February 2009 (UTC)
Playfair
editI just heard Playfair's Law mentioned on a TV quiz, and came here to find out what it was. Slightly surprised that the article as it stands doesn't say who Playfair was or when he propounded the 'law'. From further searching it seems that it was John Playfair, in his book 'Illustrations of the Huttonian Theory of the Earth', in 1802. Maybe someone more familiar with the subject can give a more precise reference?86.171.217.1 (talk) 18:24, 26 November 2014 (UTC)
This Deletion of an Unreliable Source Will Restore Your Faith in Humanity!
editI'm deleting the reference that linked to http://www.answers.com/topic/playfair-apos-s-law, as it doesn't appear to be a reliable source. It looks like a combination of Yahoo Answers (users answering each others questions then voting each other up or down) and spammy clickbait articles (20 Things That Look Like Donald Trump's Hair...), also, whatever was there in 2009 about Playfair's law, if anything, is long gone now. 76.91.100.132 (talk) 10:24, 15 August 2015 (UTC)
