For given triangles T = (A,B,C) and D = (X, Y, Z), the D-Napoleon and D-Torricelli triangles ND(T ) and TD(T ) of a triangle T = (A,B,C) are the triangles A′B′C ′ and A∗B∗C∗, where ABC ′, BCA′, CAB′, A∗BC, AB∗C, ABC∗ are similar to D. In this paper it is shown that the iteration N n D(T ) either terminates or converges (in shape) to an equilateral triangle, and that the iteration T n D (T ) eit...

The first time I sounded off in this lecture theatre was on the Great Highland Bagpipe, when I played 'The Lament for the Children' to the Scottish naturalist Seton Gordon, but have no fear I'm past all that now accordingly, at my age, I felt particularly flattered by the honour of being invited to give this Memorial Lecture.

For decades, there have been three primary anthropological perspectives on why people make war: materialist, cultural, and biological. Each has a long history of application to the Yanomami. This paper considers these three alternatives. First, it summarizes the author’s materialist models and what they are purported to explain. Second, it discusses more cultural explanations offered by several...

Since the time Napoleon “when adv...
