The project is based on an educational and museum tool designed in order to visualize the difference between the reflection in a circular mirror with that in a parabolic mirror. In the first case, a beam of parallel rays is reflected converging in an area, but not at a point; in the second, however, the same beam of rays, if parallel to the axis of the parabola, converges at a point which is exactly the focus of the parabola. The parabolic arc reproduces exactly that considered by Diocles (third century BC) to demonstrate the dioptric properties of this curve. The object consists of three essential parts: an empty niche intended to display the physical principle; an electrical device that drives the operation of two bilateral laser projectors batteries; a support frame.
