Rhombille tiling Rhombille tiling In geometry, the rhombille tiling, also known as tumbling blocks, reversible cubes, or the dice lattice, is a tessellation of identical 60° rhombi on the Euclidean plane. Each rhombus has two 60° and two 120° angles; rhombi with this shape are sometimes also called diamonds. Sets of three rhombi meet at their 120° angles and sets of six rhombi meet at their 60° angles. The rhombille tiling can be seen as a subdivision of a hexagonal tiling with each hexagon divided into three rhombi meeting at the center point of the hexagon. This subdivision represents a regular compound
A Plane Is Born on the Europa's wings and Mark puts his composite skills to the test. In part 2, he continues his flight training as he learns about climbing and descending. Nigel Marshall and Rob Cooper talk about the Pitenphol Air-camper they built at work in their lunch-hours. - You Have Control! Work on the plane continues with the Cockpit module and control yokes. Mark also receives a visit from Neville Eyre, his PFA inspector who checks to see that his work so far is air worthy. Over at Staverton Airport, it's pass the sick bag when he is introduced to "stalling". Finally,
