The world of physics is often divided into the classical and the quantum. While Newtonian mechanics governs the macroscopic world we experience daily, it falters when we delve into the subatomic realm. This is where quantum mechanics, a truly revolutionary intellectual paradigm, takes center stage. Coursera’s ‘Mécanique quantique’ course offers a rigorous and historical exploration of this fascinating field.
The course begins by confronting the limitations of classical physics at the turn of the 20th century, introducing the concept of quanta and the wave-particle duality. Early on, you’ll grapple with the probabilistic nature of quantum phenomena, a theme that underpins much of the course. The syllabus then meticulously guides you through the fundamental concept of the wave function and Schrödinger’s equation, providing practical exercises to manipulate these ideas in scenarios like wave interference.
A significant portion of the course is dedicated to the Fourier Transform, a powerful mathematical tool with broad applications in physics, including optics. Through targeted exercises, you’ll not only understand its utility in quantum mechanics but also derive Heisenberg’s uncertainty principle. The course progresses to explore operators for position and momentum, leading to the generalized Schrödinger equation that incorporates potential energy. This section delves into the stability of matter, a concept inexplicable within classical physics.
Further modules tackle the intricacies of quantum measurement, observables, and the significance of eigenstates. You’ll learn how to solve the Schrödinger equation for confined particles, with practical applications like the infinite potential well explored in detail. The course also dedicates time to individual quantum measurements and the strong form of the measurement postulate, including a deep dive into the tunnel effect through various examples like alpha radioactivity and the double potential well, which sheds light on chemical bonding and MASER technology.
Overall, ‘Mécanique quantique’ is an exceptionally well-structured course. It balances historical context with rigorous mathematical formalism, making complex concepts accessible. The inclusion of practical exercises and problem sets is invaluable for solidifying understanding. For anyone seeking to comprehend the fundamental laws governing the universe at its smallest scales, this course is a highly recommended starting point.
