I like finding simple ways to explain complicated stuff. I list some of my outreach and teaching activities below.

#### Chunky exposition

*The Penrose singularity theorem*(2020). An introduction to general relativity and singularities for high school students. I also wrote some problems and a short lay summary to go with it.*Why is a soap bubble like a railway?*(2020). Who said you couldn’t minimise without calculus? A low-tech introduction to network planning and soap bubbles. Along the way, I also touch on complexity theory, physics, curvature, tessellations, time travel and climate change. (Ok, I’m sort of joking about the last two.)*A hacker’s guide to the Chandrasekhar limit*(2020, blog post). A rough guide to how big a white dwarf (or a box of electrons) can get before it turns into a black hole.*Hacking physics from the back of a napkin*(2020, blog post) and slides [1, 2, 3]. A paean to the processing power of the napkin. Applications include clouds, urban power usage, bacterial genomics, running in the rain, asteroids, and molecular motion.*The Scrubland Manifesto*(2019, blog post). A manifesto controversially asserting that high school math should be fun, useful and engaging. Examples included.*Dimensional analysis and black holes*(2019). An in-depth introduction to dimensional analysis, fundamental constants, and black hole thermodynamics.

#### Outreach

I presented at the inaugural Teen Nerd Nite, a spinoff of Nerd Nite North Vancouver, and am involved in the COVID-friendly online version. Presentations:

*A day in the life of a theoretical physicist*(2020). A brief video about my path to physics and what a day in the life of a theorist looks like.*Black holes and the information paradox*(2020). What happens if you drop your homework into a black hole? We experiment using bits and buckets.

The UBC Physics Circle is an outreach program for high school students in the Vancouver area. I was a volunteer in 2018 and coordinated from 2019–20. Here are a few of the things I got up to:

*Physics Circle: problems and solutions*(2018–19). A medley of problems on everything from string theory to Starbucks.*Assorted scrappy notes*(2019–20). Unpolished notes on various topics.**Fermi estimates: from Harry Potter to ET**. How to estimate just about anything!**Black hole mergers**. Colliding black holes and gravitational waves.**Searching for aliens**. Fast radio bursts and extraterrestrials.

#### Teaching and course development

*An introduction to quantum computing*(2020, University of British Columbia). Various assignments for a graduate course which is in the works.*Physical systems*(2016, University of Melbourne). I created tutorials on classical mechanics and Fourier analysis for a second-year honours course in physics, and wrote assignments on higher-dimensional donuts and surfing.
