THE HEISENBERG PRINCIPLE:

• CLOSE ENCOUNTERS approach to the Heisenberg Principle. Listening to the musical theme of the Steven Spielberg's movie "Close Encounters" we can discover the Uncertainty Principle.

(Under Construction) QUANTIZATION OF THE ELECTROMAGNETIC RADIATION:

• We can count photons! Taking pictures can be a relaxing activity, but also a scientific starting point to discover the quantization of electromagnetic radiation.

(Under Construction) QUANTIZATION OF THE ENERGY LEVELS

• Energy Levels quantization. Take a straw and a bit of mathematics and investigate the energy level quantization of quantum systems.

(Under Construction) THE ACTION

• Action in Quantum Systems. Action in classical systems and in quantum systems: when h-bar becomes important.

(Under Construction) QUANTUM INTERACTIONS

• Transferred 4-momentum and quantum mechanics: scales of interactions. Particle physicist investigate the structure of matter with collisions between quantum systems. The transferred momentum plays a strong role in determining the spatial scales of the interaction.
