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.

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.

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.

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.

Mathematrix, created by Lee Stemkoski at Adelphi University, explores the playful and lesser-known side of mathematics through topics like polyominoes, Rubik's Cube, fractals, Conway's Game of Life, and higher dimensions. Accessible to curious minds at any level, the site blends mathematical art, humor, poetry, and hands-on puzzles to make recreational math genuinely entertaining.

Jeff Miller's meticulously researched reference page tracks the earliest known uses of mathematical terminology, tracing when and where specific math words first appeared in historical texts. This is a unique etymological resource for mathematicians, historians, and anyone curious about the origins of the language of mathematics.

MacTutor is a vast free archive maintained by mathematicians Edmund Robertson and John O'Connor of the University of St Andrews, featuring biographies of over 3000 mathematicians and more than 2000 historical essays. A true labor of love recognized with the Hirst Prize of the London Mathematical Society, it includes specialized indexes covering female mathematicians, mathematical societies, historical curves, and even postage stamps honoring math figures.

The Mathematics Genealogy Project is a massive academic database tracking the doctoral advisor lineages of mathematicians worldwide, with over 337,000 records linking students to their advisors across generations. Hosted by NDSU in association with the American Mathematical Society, it lets you trace the intellectual ancestry of virtually any mathematician back through history.

Pinference is an R package by PierGianLuca Porta Mana that implements probability inference for propositional logic, calculating lower and upper probability bounds for logical expressions using Hailperin's procedure. The documentation site covers the theoretical foundations connecting probability calculus to sequent calculus, with worked examples and an API reference for the inferP() function.

Alex Rutar is a mathematics postdoctoral researcher specializing in fractal geometry, dynamical systems, and dimension theory, with affiliations at the University of Jyväskylä and a PhD from the University of St Andrews. His site serves as an academic hub linking to his publications, expository writing, CV, and open-source developer tools built around LaTeX and terminal utilities.
