EDIT: Here’s a July 19 draft that fixes some of the glaring issues that were pointed out.

This morning I finally uploaded the first drafts of my Napkin project, which I’ve been working on since December 2014. See the Napkin tab above for a listing of all drafts.

Napkin is my personal exposition project, which unifies together a lot of my blog posts and even more that I haven’t written on yet into a single coherent narrative. It’s written for students who don’t know much higher math, but are curious and already are comfortable with proofs. It’s especially suited for e.g. students who did contests like USAMO and IMO.

There are still a lot of rough edges in the draft, but I haven’t been able to find much time to work on it this whole calendar year, and so I’ve finally decided the perfect is the enemy of the good and it’s about time I brought this project out of the garage.

**I’d much appreciate any comments, corrections, or suggestions, however minor**. Please let me know! I do plan to keep updating this draft as I get comments, though I can’t promise that I’ll be very fast in doing so.

Here’s a table of contents, in brief:

I. Basic Algebra and Topology

II. Linear Algebra and Multivariable Calculus

III. Groups, Rings, and More

IV. Complex Analysis

V. Quantum Algorithms

VI. Algebraic Topology I: Homotopy

VII. Category Theory

VIII. Differential Geometry

IX. Algebraic Topology II: Homology

X. Algebraic NT I: Rings of Integers

XI. Algebraic NT II: Galois and Ramification Theory

XII. Representation Theory

XIII. Algebraic Geometry I: Varieties

XIV. Algebraic Geometry II: Schemes

XV. Set Theory I: ZFC, Ordinals, and Cardinals

XVI. Set Theory II: Model Theory and Forcing

(I’ve also posted this on Reddit to try and grab a larger audience. We’ll see how that goes.)

Wait, so are you writing another book?

Guess you could call it that. Main difference is I have no plans to publish this formally.

As a mathematics amateur I would very much like it if you eventually did publish it as a printed book. I learned about it on Reddit, and I think it’s great for getting an idea of what modern mathematics is about.

Awesome! Let me know if you’d like further signal-boosting (my signal-boosting would probably mostly reach grad students in math-related fields and Bay Area techies, not sure if that’s your target audience but I suspect some of them would be interested).

hmm there is a missing figure on page 222

also page 554

Yep, some of the figures still need to be made. Will get to them one day…

On page 29, did you mean to switch from D12 to D10?

Irrelevant but when will you publish your handouts on FE, polynomials and Hall’s theorem?
