Created by physicist E. Butikov of IFMO, this collection presents interactive Java applets simulating remarkable three-body gravitational motion problems, including the famous figure-eight periodic orbit and restricted three-body scenarios. It bridges classical Newtonian mechanics and celestial mechanics with hands-on simulations suitable for students and advanced researchers exploring planetary system dynamics.

William J. Beaty, a Seattle electrical engineer, explores the fascinating physics of traffic jams, showing how waves propagate through congested highways much like fluid dynamics. The site features animations, experiments, and practical techniques for how a single driver can actually dissolve traffic slowdowns, making it a genuinely mind-expanding read for any commuter.

Maintained by Stony Brook University's physics department, this extensive link directory covers physics preprints, online journals, conferences, jobs, data sources, and institutions. Researchers and students will find hundreds of curated links spanning Physical Review, arXiv, SLAC SPIRES, astrophysics journals, and community resources like Fermilab and the Nobel Foundation.

The Chaos Group at the University of Maryland presents their research into chaotic dynamics, covering topics like fractal basin boundaries, chaotic scattering, strange attractors, and controlling chaos. Affiliated with multiple departments including Physics, Mathematics, and Electrical Engineering, this site offers a window into decades of groundbreaking nonlinear dynamics research dating back to the mid-1970s.

Julian Bunn is a computational scientist at Caltech with a background in particle physics at CERN, DESY, and the Rutherford Appleton Laboratory, now working on seismology and earthquake early warning systems like ShakeAlert. His sprawling homepage serves as a personal aide-memoire covering decades of scientific work, publications, ham radio, genetic algorithms, and even obscure retro computing projects from the DECUS era.

The Open Source Physics project, supported by NSF and the AAPT, provides free computational curriculum resources including simulations, modeling tools, and student worksheets designed to help learners explore physical phenomena through computer modeling. Highlights include the Tracker video analysis tool and Easy Java Simulations (EJS) framework, making it a comprehensive hub for physics educators and students at all levels.

David Tong, a professor at Cambridge University, offers a comprehensive collection of free lecture notes covering nearly every area of theoretical physics, from classical mechanics and electromagnetism to quantum field theory and string theory. The notes are aimed at undergraduates and graduate students and represent a genuinely deep academic resource, with dozens of individual courses each spanning multiple topics.

The Particle Adventure is an award-winning interactive guide to particle physics from the Particle Data Group at Lawrence Berkeley National Laboratory, covering quarks, neutrinos, the Higgs boson, dark matter, antimatter, and particle accelerators. Available in over a dozen languages and designed for students and curious minds alike, it offers classroom activities, particle history charts, and deep dives into the fundamental building blocks of the universe.

HyperPhysics is a sprawling educational reference site from Georgia State University covering virtually every topic in physics through an interconnected web of concept maps and concise explanations. Visitors can explore everything from classical mechanics and thermodynamics to quantum physics and relativity, with formulas, diagrams, and worked examples throughout.

John G. Cramer's subject index collects his long-running 'Alternate View' column from Analog Science Fiction & Fact Magazine, organizing hundreds of short essays on cutting-edge science into topics like quantum mechanics, cosmology, wormholes, and space drives. Running from 1984 to the present, this archive is a remarkable resource for hard SF readers and writers who want rigorous, accessible science writing from a working physicist.
