As others have already mentioned, this book is pretty funny. It's also (at the moment) accessible, even with the math thrown in there (which I rarely understand).
I like how this author takes big ideas, issues, or groups and focuses it into a person, a conversation, or just into one paragraph.
Like others, the description of humanity as a bunch of badasses was amusing, so I won't go on abot that.
I loved how he summed up academics (I'm currently writing a research paper on the problems within academic writing) by having the "tech guy" interact with Charlene and her friends. It sounded JUST like CORE class! Instead of explaining the "silliness" of academics, the author just shows it. A lot of authors have actually gone about explaining their view or point, but this is a more entertaining (in my view) way of doing it.
When Lawrence, Alan, and Rudy are talking, they cover some of the biggest debates concerning math and the world. The way he presents the classic "can everything be reduced to math" was really nicely done. I actually have this discussion with my mathematically inclined friends all the time, so I found it interesting. I am looking forward to the rest of the book.
I agree with your point about the accessibility of the novel. Even though I'm definitely not a math person. the math in this novel (so far) hasn't been intimidating--like, say, in Gravity's Rainbow. Actually, to generalize, the novel overall hasn't been intimidating so far. I feel like I can actually understand what's going on, and it's not too clouded by jargon or other things that I might not get. Definitely refreshing, as your title says.
