Before you go

Some of the posts above are for paid members only. But I have good news for you in case you have been considering joining our paid tier.

We are running a holiday campaign offering a 30% discount on the annual plan for our paid tier.

It will not only unlock all our exclusive perks for you, but also fund more math and machine learning for everyone in this community, as I plan to reinvest all the money into the newsletter.

Right now, we are at 585 paid members, and these are the tiers of perks I have in store for this community in 2026:

• 600 paid subscribers → Exclusive mini-course (Q2 2026)

  A focused, paid-members-only mini-course on a core math/ML topic (think: a deep dive you can follow step-by-step, not just a single article). The topic of the first mini-course will be “Mathematics of Machine Learning”.

• 700 paid subscribers → Another exclusive mini-course (Q4 2026)

  A second mini-course with a different expert/angle. The idea is to build an extensive course library for members.

• 800 paid subscribers → Dedicated Manim animator

  We’ll bring on a Manimator so more articles come with clean, high-quality animations that make the concepts instantly click.

• 1,000 paid subscribers → Full-time writer

  This is the big one. With a full-time writer on the team, we can ship more deep dives, more courses, and more structured learning tracks throughout 2026.

If you’re serious about your math and machine learning education, you can stay ahead of the curve in 2026:

Happy holidays,
