1 – Nature v446, 26 April 2007, p992, Bernard Chazelle, ‘The security of Knowing Nothing’

discusses the work of Boaz Barak & Amit Sahai. They use complicated cyptographic techniques to do ‘zero-knowledge proofs’ to resolve NP-complete problems enhancing online security [with an example]

2 – An arxive paper by Zur Izhakian, ‘Duality of Tropical Curves’ has figures 1-4 illustrating how to project a corner locus, subdivisions, conic duals and find a compatible Newton polytype.

Some 2D plots resemble the hexagon diagrams previously dicussed then relate them to 3D projections.

Tropical Algebra is an extension of Max-Plus Algebra that I have only recently learned of and do not yet understand
