Your best bet at this point would be https://mathacademy.com/. Their CS course will be launched between okt and dec. In the meantime I would recommend levelling up your math using the same website.

I noticed this line at the end of the article about the things you would like to build: “Education apps that leverage learning theories, community learning and game design to make learning more inspiring and accessible for students”

That’s a perfect description of mathacademy.

For a moment there I thought it was talking about this high school project, https://www.eurisko.us/
admsmz··on Show HN: Visualize rotating objects from the 4th, 5th, nth dimensions
Nice, there is a guy here live coding a tesseract on a string in javascript using geometric algebra. The code is general enough that you just have to adjust the dimension n=2,3 or 4. The rest of the code is identical.

The theory is nice but does this actually happen?

My mental model is that money in the pocket of companies is "low entropy money" and money returned to shareholders is "high entropy money".

It's the same amount, but much less effective.

admsmz··on Is parallel programming hard, and, if so, what can you do about it?
“Interaction nets” might be what you are looking for. I believe there were a couple of hackernews threads about it.
admsmz··on Everything you always wanted to know about mathematics (2013) [pdf]
What can I say. It simply wasn’t taught at our university. Instead the advanced linear algebra course focused more on abstract function spaces to prepare us for quantum mechanics. This was before the machine learning revolution.

I’ve been a paying customer since October last year. I discovered it after someone recommended it in a hackernews comment.

I’m guessing you’re mentally comparing this to all the possible books you could buy instead for that price. But how many of those books would you actually read, let alone finish? A better comparison is, having an MIT educated math tutor on call for $50 a month.

I have a bachelors in physics but it still feels great to learn new things that my education skipped. For example, we skipped singular value decomposition at my university in the interest of time. Mathacademy says, screw it, we’re teaching everything!

I'm glad the western media talked about this situation extensively before during and after the Brasilian election that ousted Bolsanero.

Everyone here is asking the right questions. How fine grained are the assessments? What is the tempo? Etc. However, I don’t see any objections that haven’t already been addressed.

This graph traversal based learning is obviously an idea whose time has come and we will probably see many similar companies spring up in the coming years.

Can you explain your objections? I don’t really understand this comment.

I am a customer of mathacademy.com, an intelligent tutoring system with a focus on math. Right now they are putting the finishing touches on their courses like abstract algebra and discrete mathematics. They already have linear algebra and calculus.

It absolutely works as advertised and I highly recommend it.

This sounds very similar to the system behind http://mathacademy.com . You follow a graph of skills and dependencies and because you always have the necessary prerequisites it is always doable.

Their team of mathematicians have created a curriculum from k-12 to a bachelors in mathematics.

Maybe a long shot but is there a course on “Geometric Algebra” offered by ASU by any chance? The founder of GA, David Hestenes is a former professor there (emeritus).

My experience has been that I never fail to make progress whenever I encounter something I didn’t know or was weak in. The system offers you plenty of practice problems, at just the right level, to make sure you master the material before moving on to material that builds on the previous lesson.

Aggressively positive? Maybe. I have been a paying customer since october and very happy with the results.

You should definitely check out mathacademy.com. They teach university level math using an AI system that is basically space-repetition on steroids.

One hour a day should be enough to make steady progress.

If people want to replicate the same feats as this kid you should check out http://mathacademy.com

People are constantly talking about chatGPT and reinforcement learning but mathacademy is using AI to teach humans. And from my experience very effectively.
