Field notes
The homepage groups its ten entries into four subject areas, with lesson descriptions ranging from proton transfer and stoichiometry to prime numbers and public-key cryptography. It describes a hands-on format in which readers change values or drag figures, and says the models are checked against independent reference values. The site also states that its text and figures use a CC BY 4.0 license and its code uses MIT.
