Editorial policy and review
How we develop learning content and what our checks cover.
Responsibility
Amos Matzke is the founder and managing director of AM Creative Tech UG (haftungsbeschränkt) in Dresden. His background includes advanced school study of mathematics, physics, chemistry and computer science at a school in the MINT-EC network, and private tutoring in mathematics and physics.
Formula reference review scope
Formula reference explanations and original exercises are developed with AI assistance. Specialist references support the models and statements used. Our example numbers are our own calculation inputs, rather than measurements published by those sources.
For developed formula reference articles, automated checks cover structure, source references and mathematical notation. A separate AI review checks calculations, model assumptions and the German and English versions. On 1 October 2026, Amos Matzke confirmed his own subject review of the version of 84 formula articles and ten reference tables published at that time. This internal editorial review does not apply automatically to later revised explanations and new exercises. An independent external subject review has not been documented.
The review information on each item defines its scope. These procedures do not constitute a subject review of the entire formula catalogue. For generated study cards, a reference identifies where information comes from; that alone does not establish its factual accuracy.
Changes and corrections
An item’s date is updated when its content actually changes. When making changes, we distinguish subject corrections, reference changes and presentation changes. A new date alone does not indicate a fresh subject review.
For a correction, please include the page address, the relevant section and a supporting reference where possible. Contact details are in the legal notice.
