Summary: Quantum physics, often considered complex, is a well-understood scientific theory crucial for modern technologies like computers and nuclear power. At its core, particles are described as waves through mathematical constructs called wave functions, which give probability distributions for their properties like position or momentum. Key concepts include the measurement problem, where the wave function collapses upon measurement, particle-wave duality, where particles exhibit both w...

The notes from lecture 1 of the course From quantum to molecule. The document contains clear images. Furthermore, it is organized and clearly marked. It is written in English with a few Dutch notes.

Quantum mechanics is a fundamental theory in physics that provides a description of the physical properties of nature at the scale of atoms and subatomic particles. It departs from classical physics in many ways, including: Quantization: energy, momentum, angular momentum, and other quantities are often restricted to discrete values. Wave-particle duality: objects have characteristics of both particles and waves. The uncertainty principle: it is impossible to simultaneously know...

Class 12 physics notes chapter 1 provides a comprehensive introduction to the fundamental concepts of electric charges and electric fields. The chapter begins with a discussion on electric charges and their properties, including the quantization of charge and the concept of Coulomb's law. Coulomb's law states that the force between two point charges is directly proportional to the product of their magnitudes and inversely proportional to the square of the distance between them. The chapter ...
