This course is for everyone who wants to learn about atomic, nuclear & particle physics: Beginners to experts!

A bit of high school mathematics is all you need to know to get started!

One of the most fundamental questions of mankind is: 'What does matter consist of?'.

Today, we know it consists of atoms which consist of electrons and the nucleus. The nucleus can be subdivided into protons and neutrons which consist of quarks and other elementary particles. In this course we will follow the same history route from atomic physics to nuclear physics to particle physics.

We will discuss different models and the experiments that proved them wrong and motivated new models. Furthermore, we learn how nuclear reactions affect our everyday life and may satisfy our electricity demand in the future.

I can guarantee that you will learn a lot no matter what your current skill level is. The first sections are phenomenological and can be well understood by high school students. The last few section really go into the theoretical details and are on a university level.

You are kindly invited to join this carefully prepared course in which we derive the following concepts from scratch. I will present examples and have prepared quizzes and exercises for all topics.


Atomic physics (4.5 hours)

  • Classical atomic models: Dalton, Thomson and Rutherford models

  • Quantum atomic models: Bohr and Schrödinger models

  • Fundamental quantities & Interactions: Mass, charge, spin & Gravity, electromagnetic interaction

Nuclear physics (5.5 hours)

  • Models of the nucleus: Liquid-drop and nuclear-shell models

  • Fundamental interactions: Strong and weak interaction

  • Radioactivity & Nuclear decay reactions

  • Nuclear fusion & Nuclear fission

Particle physics (1.5 hours)

  • Standard model of particle physics

  • Quarks, Leptons, Gauge bosons, Higgs particle & Antimatter

  • Limits of the standard model & New approaches like quantum gravity or string theory

Theoretical background (4.5 hours)

  • Quantum mechanics: Schrödinger equation, Quantized energy spectrum, atomic orbitals

  • Relativity and quantum mechanics: Spin and spin-orbit interaction

Outlook: Molecular and Condensed-matter physics (1 hour)



Why me?

My name is Börge Göbel  and I am a postdoc working as a scientist in theoretical physics. Therefore, I use presented concepts very often but I have not forgotten the time when I learned about it and still remember the problems that I and other students had.
I have refined my advisor skills as a tutor of Bachelor, Master and PhD students in theoretical physics and have other successful courses here on Udemy.

I hope you are excited and I kindly welcome you to our course!
