Oh that's cool to hear, I was under the impression in research that whilst a lot of the processing actually happens in FORTRAN-written code, it was nearly always reusing already-written functions and primitives in a higher level language (such as python, via the aforementioned SciPy). And then those libraries being maintained by a handful of wizards on the internet somewhere.
Can you elaborate on the kind of research where people are still actively writing directly in FORTRAN? Did people typically arrive with the skills already or was there training for learning how to write it well?
I think I saw a thing once where someone with ARFID would literally only eat undercooked looking french fries.
I can understand if the restriction is something unhealthy, and nothing stopping quantity, I can see this scenario happening
