Dominic Cook's personal site collects his explorations in mathematics, number theory, measure theory, and speculative metaphysics alongside creative web projects like 88x31 webpins, glitch art, and calculators. The mix of rigorous mathematical writing and old-web aesthetics makes it a quirky, intellectually curious corner of the indie web.
https://r-knott.surrey.ac.uk/Fibonacci/fib.html
Dr Ron Knott's comprehensive mathematics resource, hosted by Surrey University since 1996, covers Fibonacci numbers, the golden ratio, and their appearances in nature, art, geometry, architecture, and music. Packed with interactive calculators, puzzles, investigations, and dozens of linked pages exploring everything from Lucas sequences to phyllotaxis, this is one of the oldest and most thorough maths sites on the web.
https://hypertextbook.com/chaos
The Chaos Hypertextbook is a deep educational resource covering chaos theory, fractals, strange attractors, and fractal dimension with clear explanations aimed at making complex mathematics accessible to a broad audience. Organized into chapters covering iteration, bifurcation, Julia sets, Mandelbrot sets, and nonlinear dynamics, it reads like a beautifully structured online textbook that would captivate anyone curious about the mathematics underlying unpredictable systems.
http://mathres.kevius.com/art.html
Bruno Kevius has assembled an extensive link collection covering mathematical art, fractals, chaos theory, and geometry, featuring resources on M.C. Escher, polyhedra, cellular automata, and fractal software. With over 120 curated links spanning strange attractors, tessellations, origami, and geometric sculpture, this is a rich reference hub for anyone exploring the intersection of math and visual art.
https://cut-the-knot.org/
Created by Alexander Bogomolny starting in 1996, Cut the Knot is a massive encyclopedic collection of interactive mathematics covering geometry, algebra, probability, puzzles, proofs, and much more, built over decades until his passing in 2018. With thousands of pages, interactive Java applets, Olympiad problems, and articles spanning all levels of math, it stands as one of the most beloved and comprehensive math resources ever built on the early web.
http://euclid.psych.yorku.ca/SCS/Gallery
Hosted at York University, the Gallery of Data Visualization is a reference collection showcasing classic and contemporary examples of statistical graphics and chart design. It serves as an educational resource for students and researchers interested in how data can be effectively communicated through visual means.
https://jonathan-fraser.github.io/homepage
Jonathan Fraser, Professor of Mathematics at the University of St Andrews, maintains this academic homepage showcasing his research in fractal geometry, dimension theory, and geometric measure theory. Visitors will find links to his publications, research papers, talks, course notes, and resources related to his book on Assouad Dimension and Fractal Geometry.
https://www.andrews.edu/~burton/mathlinks/coolmathlinks.htm
A curated collection of mathematics education links compiled at Andrews University, organized into sections for teachers, parents, and students across K-12 grade levels. The directory covers lesson plans, interactive activities, problem-solving resources, and NCTM-aligned curriculum materials from across the early web.
https://idenified-flying-object.nekoweb.org/
Iden's personal corner of the web highlights their love of mathematics, featuring a playful 'Web Pi' page and a collection of 88x31 buttons alongside a blog and micro-log. The site has a charming lo-fi aesthetic with CC0-licensed content and participates in the No AI Webring.
https://hermetic.ch/cal_stud/jdn.htm
Peter Meyer's detailed reference article explains the Julian Day Number system, covering its origins, astronomical vs. chronological uses, and various related date formats like Modified Julian Day Numbers and Lilian Day Numbers. The page includes conversion algorithms and links to calendar software tools, making it a thorough technical reference for astronomers, historians, and calendricists.
