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.

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.

A lecture page from a University of Houston astronomy course (ASTR 3131) explaining Einstein's theory of general relativity and the concept of curved spacetime. It covers how mass and energy deform the fabric of spacetime, using accessible analogies like a ball on a bedsheet to illustrate four-dimensional curvature.

Created by Norman Hugh Redington at MIT, The Net Advance of Physics is an encyclopedic collection of review articles and tutorials covering the full breadth of physics, organized alphabetically and continuously updated since 1995. Special features include a 19th century physics retro archive, history of science resources, a science poetry collection, and curated links to recent controversies in the field.

HEPData is an open repository for publication-related High-Energy Physics data, hosting experimental datasets from major LHC collaborations including ATLAS, ALICE, CMS, and LHCb. Researchers can search and submit data using advanced query syntax, making it an essential reference tool for particle physics scientists worldwide.

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 official homepage of Gerard 't Hooft, Nobel Prize-winning theoretical physicist at Utrecht University, covering his research into quantum mechanics, quantum field theory, and black hole physics. Visitors can access his lecture notes, publication list, curriculum vitae, and his ongoing work on deterministic quantum mechanics and the origins of quantum behavior.

James Ziegler's authoritative site hosts SRIM and TRIM, widely used scientific software packages that calculate the stopping and range of ions in matter for research and engineering applications. The site includes downloadable software, textbooks, tutorials, a historical review spanning 100 years of ion stopping research, and resources covering topics from cosmic ray soft errors to neutron damage.

Founded in 1995 by physicist Anton Skorucak, PhysLink.com is a comprehensive online portal covering physics and astronomy through reference materials, expert Q&A, physical constants, calculators, and educational articles. Visitors can explore everything from quantum mechanics and general relativity to astronomy news, Nobel Prize info, and even physics humor and cartoons.

Mike Daub is a physics and mathematics educator with a master's from UC Berkeley who spent five seasons at the South Pole researching experimental cosmology on the ACBAR project. His personal site covers his academic background, libertarian politics, photography, and a no-nonsense hand-coded HTML philosophy with no frameworks or tracking.
