Tracing a planet's orbit with a straight hedge and a compass with the help of the hodograph and the Hamilton vector
E. Guillaumín-España, H. N. Núñez-Yépez, A. L. Salas-Brito
We describe a geometrical method for tracing a planet's orbit using its velocity hodograph, that is, the path of the planet's velocity. The method requires only a straight edge, a…

Simple quantum systems in the momentum representation
H. N. Núñez-Yépez, E. Guillaumín-España, R. P. Martínez-y-Romero +1
The momentum representation is seldom used in quantum mechanics courses. Some students are thence surprised by the change in viewpoint when, in doing advanced work, they have to us…

From circular paths to elliptic orbits: A geometric approach to Kepler's motion
A. González-Villanueva, E. Guillaumín-España, R. P. Martínez-y-Romero +2
The hodograph, i.e. the path traced by a body in velocity space, was introduced by Hamilton in 1846 as an alternative for studying certain dynamical problems. The hodograph of the…
