I know of Matt Parker mostly through his podcast and YouTube channel, and I picked up his latest book LOVE TRIANGLE because I generally like his work. This book is, if you can guess from the title, about triangles and trigonometry, starting with basics like Pythagoras and moving through measuring the sizes of planets and galaxies to end up at circles. Overall, I liked it, though like many nonfiction books it wasn't what I'd call a page-turner. Not that that's a problem---I just read it over many settings and don't have a complete picture of it in my mind, like I do of many novels (at least soon after I finish them).
I like Parker's amiable, fun-teacher style of writing, and the illustrative diagrams are amusing and informative. But there was something about this book that just ... it didn't feel totally finished. Maybe partly because the last chapter is a big list of things that he wasn't able to get to in the space alloted (spoiler alert!). Maybe I'm saying that I wish I had more of his writing on triangles to read, which is a good thing really.
At any rate, Parker is a good science and math communicator who is firmly in the popular milieu. You know, maybe that's the thing---I'd like a text with a bit more *techne*, one that trusts that I can follow a more advanced argument. If any readers of this know of any books on trigonometry that fit this bill, feel free to drop me a line.
