How to use this website

The website is structured in two parts: The learning path and the laboratory. Both have different scopes. The learning path provides the information and guides you through the topics. At several points you are assigned to accomplish an experimental challenges in the virtual laboratory where you can apply your knowledge.

The learning path

The learning path consists of two sections:

  • The basics learning path: targets high school students and the public. It covers simple grating diffraction that is known from many school text books, but in the context of a modern research experiment. You will need 1 hour to go through the topics and experimental tasks.
  • The advanced learning path: targets university students and people that have mastered the basics learning path. It goes deeper into the topics of high mass quantum interference and the scientific challenges. You will need 3-4 hours to go through all of the topics and experimental tasks.

Both parts of the learning path show mostly qualitative information, but encompasses also detailed quantitative information in optional subsections like this.
