Matrix Calculus (For Machine Learning and Beyond) (arxiv.org)
This course, intended for undergraduates familiar with elementary calculus and linear algebra, introduces the extension of differential calculus to functions on more general vector spaces, such as functions that take as input a matrix and return a matrix inverse or factorization, derivatives of ODE solutions, and even stochastic derivatives of random functions.

Accessible open textbooks in math-heavy disciplines (richardzach.org)
The authoring platform of choice in many math-heavy disciplines is LaTeX. It produces typeset documents of excellent quality and handles formulas and mathematical diagrams extremely well. Practically every researcher or instructor in mathematics, physics, and computer science is adept at using it, and it has a wide user base outside these core disciplines as well (e.g., philosophy and economics).

The Matrix Calculus You Need for Deep Learning (explained.ai)
Most of us last saw calculus in school, but derivatives are a critical part of machine learning, particularly deep neural networks, which are trained by optimizing a loss function.

Escher's Art and Computer Science (replicated.wiki)
While on a small vacation in the Hague I had a blissful chance to visit the Escher’s museum. It is now hosted in an actual royal palace which many Europeans may find surprisingly modest. Maurits Cornelius Escher was a 1940x Dutch graphic artist known for his math-rich works.

Mathematicians uncover the logic behind how people walk in crowds (news.mit.edu)
Next time you cross a crowded plaza, crosswalk, or airport concourse, take note of the pedestrian flow. Are people walking in orderly lanes, single-file, to their respective destinations? Or is it a haphazard tangle of personal trajectories, as people dodge and weave through the crowd?

Peano's Axioms (principlesofcryptography.com)
Thinking of numbers intuitively brings to mind the simplest and most fundamental set of numbers, namely the set of natural numbers. These numbers are used to count objects like cars, books, pens, etc. If we associate natural numbers such as 1, 2, 3, etc. with counting, then with what corresponding concepts do we relate numbers like -4, \sqrt{3} \text{ and } \frac{22}{7}?
