With the aim to promote a deeper understading of ThetaHealing and QTR techniques, the course addresses the key concepts of classical physics - energy, power, potential difference and electric intensity, frequency, resonance, elettromagnetic fields, nature of light and optical phenomena - in a simple but effective way. Fundamentals of quantum physics, with particular attention to the birth and the evolution of the discipline and references to its different interpretations will also be discussed. Moreover, the class will cover topics such as the theories of relativity, astrophysics, Big Bang and black holes.
