@freemo Reading math as basically all I do at this point in my PhD and I still find myself going at a rate of about an hour a page for some work, sometimes due to its genuine density, and sometimes due to the quality of the exposition. It's exhausting. Math, by its very nature, is built out of definitions and theorems, including these necessary pieces in your work is hard enough, communicating the intuition and ideas on top of that is something very few people can do effectively.
