Fundamental Principles of Quantum Mechanics

An Introduction to the Fundamental Concepts and Principles of Quantum Mechanics

What is light—a wave or a particle? Is an electron a microscopic ball that orbits the nucleus? How is it possible for material particles to exhibit wave-like behavior? How can two mutually exclusive concepts—such as those of a wave and a particle—be reconciled? What, after all, is an electron? How did a glowing, incandescent metal—such as the tungsten filament of a light bulb—lead to the birth of quantum physics? How did Einstein prove that light has a particle nature? What is the spin of an electron? What does the double-slit experiment tell us about the nature of observation? What are entangled particles? Does quantum physics have applications in our daily lives?

The “Fundamentals of Quantum Mechanics” experiment demonstration for 12th-grade students is designed to introduce students to the basic principles of quantum theory. The main purpose of the experiment demonstration is to highlight how everyday phenomena—which could not be explained by classical physics— led scientists to introduce paradoxical ideas and ultimately led to the establishment of quantum physics. Finally, these experiments highlight the probabilistic nature of the theory, which stands in stark contrast to the deterministic view of reality that has become ingrained in students’ minds through classical physics.
