Spherical cats would be a lot easier for many calculations due to simplified boundary conditions.

One of my favorite jokes ends with “let us assume a spherical cow.” My wife hates that one.

Seek is also a decent alternative if you want quick results with minimal steps. It’s a more casual experience. You basically scan your specimen with Seek on live video and it identifies it in real-time. You miss out on the iNaturalist community help, but you can link Seek to your iNaturalist account to share observations.

OP must follow Rox News.

Not to be picky, but It appears that whoever(whatever) wrote this can’t differentiate the country of Mexico and the state of New Mexico in the USA. Hmmmm

Calculations are simpler if ……… you assume a spherical cow!

It was based on good old fate and transport processes and plenty of scientific data (as opposed to made up hearsay?). It served us well for that sucky situation we were in. .
