Peter Woit's 'Not Even Wrong' is a long-running physics blog hosted at Columbia University, covering cutting-edge topics in theoretical physics including twistor theory, quantum field theory, and the mathematics of unification. Woit writes with deep technical expertise and a critical perspective, making this a destination for mathematically sophisticated readers interested in the foundations of modern physics.

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.

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.

Created by a University of Toronto physicist, this collection features 99 Flash animations covering topics from Quantum Mechanics and Relativity to Chaos and Fluid Mechanics, making abstract physics concepts visually intuitive. A bonus tutorial teaches how to build your own physics animations in Flash, and the animations are available in multiple languages under a Creative Commons license.

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.

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.

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.

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.

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.
