These mathematics and theory videos come from HackerTube, Andrej Karpathy’s index of YouTube links found in Hacker News comments. This independent hub groups the material into clearer entry points without presenting the directory as a formal syllabus.
Start with the idea you want to see
Visual explanations are especially useful when symbols hide the shape of an argument. Begin with vectors or calculus for broad foundations, then branch into probability, information theory, algorithms, logic or computability according to the question you are trying to answer.
Connect intuition to applications
The featured route moves from geometric foundations to curves, signals, Bayesian reasoning and error correction. Those transitions show how mathematical ideas reappear in graphics, data, communications and computer science rather than leaving each topic in isolation.
Use the directory alongside a structured course
Hacker News discussion can surface unusually clear explanations, but a recommended video may cover one insight rather than a full subject. Use this hub to find an explanation that unlocks a concept, then return to a textbook, course or problem set when you need systematic practice.
The visual path starts with vectors and calculus, then builds toward curves, Fourier analysis, probability and information.
