Bookish collections of physics and math writing
On this blog (or my old blog) are many article sized bits of writing that were eventually incorporated into “bookish” compilations (a total of about 5800 pages of pdfs):

 Geometric Algebra for Electrical Engineers. This was the product of an ECE2500 project course, and is structured much more like an actual book than many of the more exploratory works below. It still needs lots of work and polish, but has the fundamentals in place.
 Exploring physics with Geometric Algebra, Book I. This part of my Geometric Algebra collection includes introductory Geometric Algebra content with the following topics:
 Basics and Geometry
 Projection
 Rotation
 Calculus
 General Physics
 Exploring physics with Geometric Algebra, Book II. This second part of my Geometric Algebra collection includes touches topics that requires more advanced physics:
 Relativity
 Electrodynamics
 Lorentz Force
 Electrodynamics Stress Energy
 Quantum Mechanics
 Fourier treatments
 Misc Physics and Math Play. This is a collection of odds and ends that were not associated with a specific topic or course.
 Classical mechanics. This includes a fair amount of selfstudy material related to the theory of Lagrangians, Hamiltonians, and Noether’s theorem that were originally in the Geometric Algebra compilation above. Also includes notes and a couple problems from occasional Wednesday audits of 2012 University of Toronto PHY354H1S, Advanced Classical Mechanics,taught by Prof. Erich Poppitz.
 Quantum Physics I (PHY356H1F), taught by Prof. Vatche Deyirmenjian, fall 2010.
 Relativistic Electrodynamics (PHY450H1S), taught by Prof. Erich Poppitz, spring 2011.
 Quantum Physics II (PHY456H1F), taught 2011 by Prof. John E. Sipe, fall 2011.
 Continuum Mechanics (PHY454H1S), taught by Prof. Kausik S. Das, spring 2012.
 Advanced Classical Optics (PHY485H1F), taught by Prof. Joseph H. Thywissen, fall 2012.
 Basic Statistical Mechanics (PHY452H1S), taught by Prof. Arun Paramekanti, spring 2013.
 Condensed Matter Physics (PHY487H1F), taught by Prof. Stephen Julian, fall 2013.
 Advanced Antenna Theory (ECE1229H1S), taught by Prof. G.V. Eleftheriades, spring 2015.
 Winter 2016: ECE1236H “Microwave and MillimeterWave Techniques”, taught by Prof. G.V. Eleftheriades.
 These microwave notes are incomplet as I dropped the course, to concentrate on phy1610, Scientific Computing for Physicists which I was taking concurrently. Two simultaneous courses was difficult on a part time schedule.
Some of these courses were undergrad physics courses taken part time in 20102013 as a nondegree student at the University of Toronto, and others were taken as part of a part time UofT M.Eng degree program taken throughout 20142018.
See physicsplaygit for the latex sources of all these notes.
Redacted course notes.
The following course notes have problem set solutions, project related content if applicable, and links to some associated computer algebra notebooks (Matlab, Mathematica, Julia, …) all redacted. For each of the courses below problem set solutions are replaced by CIAstyle blackout marks;)
Feel free to contact me for the complete version (i.e. including my problem set solutions) of any of these notes, provided you are not asking because you are taking or planning to take this course.

 Modeling of Multiphysics Systems (ECE1254H1F), taught by Prof. Piero Triverio, fall 2014. (redacted: 196 pages, full version 300 pages.)
 Graduate Quantum Mechanics (PHY1520H), taught by Prof. Arun Paramekanti, fall 2015. (redacted: 358 pages, full version: 434 pages).
 Electromagnetic Theory (ECE1228H), taught by Prof. M. Mojahedi, fall 2016. (redacted: 183 pages, full version 256 pages).
 Convex Optimization (ECE1505H), taught by Prof. S. Draper, winter 2017. (redacted: 131 pages, full version 149 pages).These convex optimization notes are incomplet, covering only the first 9 lectures. The unredacted notes include my solution to problem set 1.
 Quantum Field Theory I (PHY2403F), taught this year by Prof. Erich Poppitz. Course home page: Quantum Field Theory I. (redacted: 316 pages, full version 409 pages). This course covered a subset of the first ~125 pages of Peskin and Schroeder’s Introduction to Quantum Field Theory (an 800 page introduction!)
On Geometric Algebra
A couple of references that I feel cover this material much better than my ‘exploring physics with geometric algebra’ books are:
 Geometric Algebra for Computer Science: An ObjectOriented Approach to Geometry, by Leo Dorst, Daniel Fontijne, and Stephen Mann.
 Linear and Geometric Algebra, by Alan MacDonald
 Vector and Geometric Calculus, by Alan MacDonald
A lot of my earlier GA notes were exploring papers that I found scattered around the web at the time. There’s now much more available, including a number of tutorials. A lot of my later GA notes where notes from reading Geometric Algebra for Physicists, by Chris Doran, and Anthony Lasenby. That is a book that was too advanced for me at the time I tried to read it, so my attempt to read it required a lot of additional rumination.
Blurbs on atomics, memory ordering and barriers
 An attempt to illustrate differences between memory ordering and atomic access
 A nice simple example of a memory barrier requirement

Other misc bits of writing that I liked (at least when I wrote them) :
 Change of basis and GramSchmidt orthonormalization in special relativity (an arxiv posting just for fun … never tried to publish it formally)
 Relativistic origins of the Schrodinger equation (following Pauli’s treatment which I liked, but found too dense for my taste)
 Spherical polar pendulum for one and multiple masses (Geometric algebra used for the multiple spherical pendulum problem)
 Lagrangian and EulerLagrange equation evaluation for the spherical Npendulum problem (same as above, but using plain old rotation matrices instead of geometric algebra)
