PhysicsKG
An Atlas of Physics Knowledge
Explore the ideas of special and general relativity as a navigable knowledge graph. See the broad structure through teaching modules, then open individual concepts for equations, explanations, graphics, historical context and study questions.
See the wood—and the trees
PhysicsKG organises a large subject without turning it into either a rigid textbook sequence or an unreadable tangle of links.
Folded modules reveal the main intellectual landscape. Expand one to work with its concepts, or follow carefully typed relationships to see prerequisites, derivations and uses across the atlas.
Understand
Read mathematical exposition, view purpose-made graphics and connect equations to physical meaning.
Study
Answer questions, mark reading progress and keep notes alongside the relevant material.
Personal work remains personal
Local first, portable by choice
Notes, layouts, reading ticks and study-question records stay in your browser by default. You can download them as transparent CSV files in a ZIP archive, or optionally synchronise the same archive through your own Google Drive.
- No PhysicsKG account
No application server holds your study record. - Narrow Drive access
PhysicsKG requests only Google'sdrive.filescope. - User initiated
Connection and synchronisation happen only when you choose them.
