Try this physics paper[1] explaining how pretty much every model we have of physics is broken in fundamental ways. Things you take for granted because of what you've read in popular media (eg., heat death of the universe) are simply sp

There is a large, emerging body of research in which one proves the impossibility of solving problem A by finding an algorithm for solving a different problem B. For Mulmuley et al. (it's been a while since I was in the thick of this)

I think the first chapter definitely has no prerequisites (it introduces sets and categories), but it's also a core mathematics textbook intended for upper-level undergraduate and early graduate students in pure mathematics. So it re-t

The linked article explains how a single human brain neuron is a lot more complex than previously thought. Obvious is also a word we should avoid using in discussions about brain biology.

I read somewhere[1] that because we know far more now about human neurons than we did five years ago, modern CNN's are better compared to a _single_ neuron (but are probably still simpler than them). I'm far from an expert in brai

Go read the first few chapters of Algebra Chapter 0, and do the exercises. There's a free copy online somewhere... This is the book that really demystifies it from the ground up.

I think the GP's point is that just because something is possible in principle, complexity is still a barrier in practice, probably a much more serious barrier than accepting an idea on principle

Yup! My goal was more to explain the math than anything else. I was planning to extend this for 25519 and discuss the alternate standard forms, but instead I'm trying to finish up that darned book.

This may only be sort of relevant, but I write a math/programming blog on which I implemented a (very inefficient) elliptic curve crypto library from first principles. This includes all the math background, and implementations of a few

Thanks! I'll be looking into these. From a first glance, Coding the Matrix looks to be excellent and exhaustively complete, but also very verbose. From Mathematics to Generic Programming appears to be the kind of book I want to avoid.

I should also mention that I don't expect every programmer to find career value out of the book. I like math, I hear from a lot of programmers who want to like math more (for fun or side projects or work), and I feel like I'm in a

In anticipating a book like this, would you ideally want to learn the math context and notation (provided one goal of the book is to teach that), or skip that entirely in favor of the underlying ideas (as in your example with Newton's
