Giacomo Domeniconi,Gianluca Moro,Andrea Pagliarani,Roberto Pasoliniancient Egyptians in order to construct right angles. Conversely, however, distances cannot be determined only from angles. But there is a geometry with the angle as its only basic notion, called . geometry; it is much less known than metric geometry. Its “isomorphisms” are the conformal (i.e. angle

Carmelo Spiccia,Agnese Augello,Giovanni Pilatoaccessible to our geometric intuition, making it possible to develop elementary geometry in a way very similar to that used to create the geometry we learned at school. However, since its basic notions can be interpreted in different ways, this geometry can be applied to objects other than the conve

Fabio Sartori,Riccardo Melen that oscillate. They move about at constant velocity unless there is a collision, either at an endpoint or in encountering each other. The conditions in case of collision are these: when the particle on the left encounters the wall on the left at 0, it rebounds with the same speed and of course in
