Linear Algebra: Step by Step
Kuldeep Singh
Oxford University Press, 2013
Vectors
Dot Product
Cross Product
Linear Algebra
Supplementary reference for the linear algebra section alongside 3Blue1Brown. Provides formal algebraic treatment alongside 3B1B's geometric approach.
Ordinary Differential Equations
V.I. Arnold, trans. Silverman
MIT Press, 1978
ODE Overview
Slope Fields
Pendulum
Phase Portraits
Source for the ODE overview and pendulum lessons. Arnold's geometric/qualitative approach — phase portraits, slope fields, separatrices — shapes how the visualizations are framed.
PHASE 4
Understanding Analysis
Stephen Abbott
Springer, Undergraduate Texts in Mathematics · 2nd ed.
Real Analysis
Sequences
Continuity
Riemann Integral
Real analysis foundation before Armstrong's topology. Abbott's §3 (topology of ℝ — open sets, compactness, connectedness) directly prepares for Armstrong's general treatment. Oct–Dec 2026.
PHASE 5
Basic Topology
M.A. Armstrong
Springer, Undergraduate Texts in Mathematics
Topology
Homeomorphisms
Fundamental Group
Surfaces
Planned source for the topology section. Covers point-set topology through to algebraic topology — connectedness, compactness, classification of surfaces, simplicial homology. Jan–Apr 2027.
PHASE 6
Introduction to Probability
Joseph K. Blitzstein & Jessica Hwang
CRC Press / Chapman & Hall, 2014
Probability
Random Variables
Distributions
Markov Chains
Primary probability source. Developed from Harvard Stat 110 lectures (free on YouTube). Covers counting, Bayes, distributions, expectation, limit theorems, and Markov chains. Apr 2027+.
