3. Illumination problem - Wikipedia

   en.wikipedia.org/wiki/Illumination_problem

   This problem was also solved for polygonal rooms by George Tokarsky in 1995 for 2 and 3 dimensions, which showed that there exists an unilluminable polygonal 26-sided room with a "dark spot" which is not illuminated from another point in the room, even allowing for repeated reflections. [1]

   Small's style of math instruction has been described as a "random abstract approach" by those favouring more traditional skills-based pedagogy. [7] Toronto's Globe and Mail stated: "in the latest—arguably fiercest—of the "math wars" to break out in Canada, she would be Public Enemy No. 1 for those who think kids are fast losing their number sense because of the "fuzzy-math, basic-skills ...

5. Inversive geometry - Wikipedia

   en.wikipedia.org/wiki/Inversive_geometry

   When two hyperplanes intersect in an (n–2)-flat, successive reflections produce a rotation where every point of the (n–2)-flat is a fixed point of each reflection and thus of the composition. Any combination of reflections, translations, and rotations is called an isometry .
