I think notation is completely misunderstood by some fields, and that physics in particular really shows the benefits of it (i.e. With tensors and feynman diagrams we can nearly stop ourselves from writing down the wrong answer through notation), but academics are just as idiosyncratic as everyone else so I'd guess something more human.

I've got terrible mathematical education, but Feynman diagrams are something even a clown like myself can easily wrap his head around. They're really an exceedingly clever device, end "clever" doesn't do it justice.

  They don't even have to be Feynman diagrams - theoretical (rather than mathematical) physicists are usually pretty lazy. We make up notation for us rather than the reader. Mathematicians, I find, are a lot worse but still bearable. Engineers though, oh boy, seem to actively enjoy using notation to obscure the material in the books I have read.

I bought ~5 different kindle books on logic as a prerequisite for understanding another book I originally bought on Probability Theory (E. T. Jaynes). Every logic book I bought used a different notation and none of them matched the notation used in the book I wanted to read either, which is how I ended up with 5 of them. You'd think something as straight forward as (boolean) logic would converge on a standard notation. But I'm not familiar with the mathematics field to really criticize this. Regardless I found it to be a large barrier-to-entry which over complicated something when I was hoping to find direct analogies not needing constant 'translation'.

  I agree. What I saw with the mathematics students during our Bachelors (I did CS, so adjacent, but still far away) was that they would have a really hard time in the beginning coming from school, but after a few semesters they would transcend notations and it would then become mostly a thing of preference. The thing is that all of these guys were already really talented and engaged in mathematics, and it was still quite hard combined with the fundamental difference of how we do mathematics in university compared to school.

    That gives me some motivation to power through them until I get used to the notation. Thanks.

  In programming language theory there is a unified notation for operational semantics, but most papers use nonstandard and/or incorrect interpretations of the notation. It’s a glorious minefield when you go to try to implement the papers — you inevitably end up talking to the authors & helping them debug issues, even years later.
