Galileo's Quantization

In the context of physics didactics, alternative instructional approaches have often been employed to facilitate conceptual understanding of various topics. In this article, an alternative formulation for analyzing the motion of bodies on inclined planes is presented, based on Galileo's experimental rule involving multiples of odd numbers. According to this, bodies traverse distances that increase in odd multiples of an initial amount during successive equal time intervals. In the proposed formulation, a function is established between distance, whether ascending or descending, and time, omitting the use of Newtonian concepts such as velocity, acceleration, or force. The theoretical exploration of this formulation may provide significant didactical benefits, offering scenarios for discussion and reflection in physics didactics.

Theoretical photon origin, a didactic introduction to the wave particle duality

In modern physics courses the idea of photon has been teaching through from the einsteinian formulation based on the photoelectric effect. Einstein's photon concept allow the quantization of the electromagnetic field, but does not dwell on the idea of photon as particle. The objective of this paper was to demonstrate that the photon has its origin essentially in the special relativity, the electromagnetic theory and in the symmetry between the Lorentz's transformations associated flat monochromatic electromagnetic waves and particles with zero rest mass. This approach allows to understand the wave-particle duality of photon and allows to propose an alternative teaching focused on this duality to develop the course of modern physics.
