 Hi Victor,

Here is a new discovery that may be of interest to your readers at Daily Speculations, and which may serve as introduction to my Junto presentation on 3 September:

"Why humans build fires shaped the same way"

It has generated a wave of interest on the web during the past few days.

Here is an excerpt from the Abstract:

Here we see why humans unwittingly build fires that look the same: edifices of fuel, as tall as they are wide. I show that the hottest pile of burning fuel occurs when the height of the pile is roughly the same as its base diameter. Key is why humans of all eras have been relying on this design of fire "unwittingly". The reason is that the heat flow from fire facilitates the movement, spreading, and survival of humans on the globe.

With best wishes,

Adrian

Gary Phillips adds: 

I wonder if there are corollaries from the abelian sandpile model that are relevant to the ways fires are built and subsequently burn.
