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.

Richard Fitzpatrick is a Professor of Physics at the University of Texas at Austin, specializing in fusion studies, with this page serving as a hub for his research, teaching materials, academic papers, talks, and books. Visitors interested in plasma physics or fusion energy will find a gateway to substantial scholarly resources from an active academic researcher.

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.

The official site for NASA's Gravity Probe B mission, a Stanford University experiment designed to test two key predictions of Einstein's general theory of relativity using ultra-precise gyroscopes orbiting Earth. Visitors can explore the mission's history dating back to 1959, the groundbreaking engineering advances required to make it possible, technical papers, image galleries, and video overviews of spacetime concepts.

A physics professor at SUNY Stony Brook takes aim at pseudoscience and scientific quackery, exploring the psychological and personality traits that lead people to reject well-established science like evolution, vaccination, and modern physics. The page is a sharp, witty critique of fringe theorists who show up insisting their ideas will overturn all known physics, drawing a careful distinction between bold legitimate scientists and true cranks.

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.

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.

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.

PhysicsPages is a detailed self-study companion covering classical mechanics, quantum mechanics, electrodynamics, relativity, string theory, and more, written with honest, jargon-free explanations that avoid the dreaded 'obviously' of typical textbooks. The creator presents rigorous, math-heavy notes designed for university students or independent learners working through structured physics topics.
