@anemofilia Neat! Although I think flipping the radical has a better shot at widespread use due to the amount of space the triangle notation takes up.

Why don't we write the logarithm like this? It feels like teaching students what logarithms are is way more painful than teaching roots, but this notation emphasizes that they are perfectly analogous.

I can provide my rough #TexLatex source for this if people are interested.

@oantolin For whatever it's worth, I'm American and I don't think you're overreacting. For similar reasons I'd only leave the US in the near future if I didn't intend to return. Flying here is a bit scary now, anyway.

This is a friendly reminder that
((1+𝑥)ʸ+(1+𝑥+𝑥²)ʸ)ˣ⋅((1+𝑥³)ˣ+(1+𝑥²+𝑥⁴)ˣ)ʸ=((1+𝑥)ˣ+(1+𝑥+𝑥²)ˣ)ʸ⋅((1+𝑥³)ʸ+(1+𝑥²+𝑥⁴)ʸ)ˣ for all natural numbers \(x\) and \(y\), but this formula is impossible to obtain by using only those arithmetic laws taught in high school. Credit for this goes to Alex Wilkie, who found this in the 1980s.

I updated my bio. I am still interested in machine learning, and I am continuing my own projects in this area, but this terminology has become synonymous with an ideology and culture to which I am diametrically opposed.

There is great value in tools like optical character recognition, speech recognition, and machine translation (when ethically applied). However, the current regime selling machine learning tools as products is completely disconnected from what I would view as a healthy and productive contribution to society.

I would still like to contribute to practical applications of mathematics in the world, and I hope that academia will continue to support my efforts to contribute in a way that supports everyone, not just a small cadre of plutocrats.
