A cool idea that I will never check out due to a subscription model. Cool thinking though!

Thank you for your feedback! We are pretty straightforward about the subscription model — we don't sell ads or user data. And also it keeps the environment safe and the community culture friendly and respectful.

That exaggerated oppression claim only reinforces the heuristic. In reality, approximately 99% of the time people use the correct pronouns based on name and appearance. The remaining rare cases consist of honest mistakes (that can be politely corrected) or bullies (who the rest of us already denounce).

How's the emerald mining curriculum?

Stillwell's _Mathematics and its History_ is, imo, excellent.

Stillwell is a fantastic historian, +1 to the recommendation.

It is a fantastic book, but unfortunately (as far as I can tell) seems to be out of print in paperback, which is a shame.

If you have an American Amazon account, you can get most of Greg Egan's books on Kindle for $2 a pop.

The book that got me back into mathematics and computers, and led me into CS. Can't recommend it enough.
