This is pretty understandable because:

1. They explain all abbreviations at the top.

2. There is a lenghty text explaining the formula.

3. It's mathematically pretty easy if you know partial differentation.

Also scientists and engineers write pretty horrible code....

It’s not horrible, it’s different, has different goals and different audiences. Context is king, and the bulk of professional programmers criticizing scientist code is just lack of context and a different set of priorities.

From a more science based background i often think programmers write horrible code as i search in vain for where anything actually happens in a sea of abstractions.
