currently bootstrapping in toronto
- much lower cost of living than sf, nyc, miami
- talent pool is dense
- SR&ED credit (up to 40% of salary back on tax)
- waterloo grads spawn nearby
- sell in USD, spend in CAD

Unit 0: Preparing for Physics is now live on PhysicsGraph!

Placed at the beginning of our physics courses, this unit ensures you're familiar with some of the basic tools used to study physics.

as i say in this piece: there's absolutely no reason it should take this long. Canadian taxpayers deserve efficient and modern government services

the execution is just not there on this file ... and with the rest of the world moving as quickly as they are, we can't afford to go this slowly

Build Canada first published ideas on how AI adoption within government could transform Canada's public service in February 2025 ..... nearly 18 months ago...

Canada 🇨🇦. Trudeau and Carney wanted net zero, and they got it: zero growth, zero jobs, and zero productivity.

@ToKTeacher @AISafetyMemes Recently, AI models have solved decades-old open mathematical problems, including several of the famous Erdős conjectures. While the media often portrays this as AI "inventing new math," the reality is much more grounded in how these models actually function.

If you are interested in supporting foundational research, Paul deserves your support.

[Paul Raymond-Robichaud @PaulRRobichaud]

I solved a foundational problem for quantum mechanics and all future physics. I am seeking independent patronage to continue unhurried, foundational research.

@suekhim Cool!

The graph is beautiful, but the real value is in what it can do for you: maximize your learning and minimize your frustration

[Lucy Hargreaves @lucyhargreaves4]

every forecast had this quarter pegged as the rebound. ottawa projected +1.4%. rbc and td both said +1.7%. q4 was the dip, q1 was supposed to be the recovery.
we got roughly zero growth

yes, this is a technical recession but
the longer pattern is what really matters and what concerns me most

real gdp per person grew 0.6% in all of 2025. it fell in 2024. it fell in 2023.

we haven’t become richer per person in years, and it’s crazy to me that we keep acting surprised when our growth is stalled

we have fundamental productivity and investment problems that won’t fix themselves

I will sound like I’m beating a dead horse here, but worth repeating again… we know what we need to do to fix this:

1. make capital gains and corporate tax rates at least as good with the US, if not materially better. across all industries.

2. open up protected markets to competition (telecoms, finance, dairy, transportation etc)

3. rapidly reduce bureaucratic red tape and slow process across the board, not just for favoured projects or sectors

and finally, let’s all remind ourselves that we can just do things. every Canadian can be part of fixing this. we can collectively hustle - aim high

Canada can be the richest country in the world, if we choose to be

Our map of physics I grows ever more detailed

[Chris @sutherlandphys]

Do not try this at home. Or do, and then just come use PhysicsGraph :)

Obsessed with @physicsgraph's knowledge graph.

Each one of those hundreds of tiny nodes contains between 2-4 subtopics with their own explanations, examples, and practice, connected in a way that ensures you'll never encounter something you aren't ready for.

Newly updated unit: Work, Energy, and Power

Thank you @camarraluca for all your hard work in making this amazing!

One of the incredible things you learn at a small startup is: making anything actually work is ridiculously hard

When the company is small, you have no one to blame but yourself and the difficulty of the task at hand.

Without that learning, many people bounce from big company to big company with failed projects, constantly blaming the failure on other people (or, incorrectly attributing success to their own actions, and believing things were much easier than they actually were)

I need all universities to stop using textbooks immediately. Use PhysicsGraph
