Ten ideas that break classical intuition.
A hands-on walk through quantum mechanics — from a single particle in superposition to the edge of what physics currently knows. Ten topics, each with its own interactive demo and the real physics underneath it, checked against the primary literature rather than restated from memory.
This site runs on one idea: real science — the actual math, not a simplified cartoon of it — should be something anyone curious enough to show up can understand, not only people who already have the coursework behind them. Translate a real result accurately, keep the parts that are still genuinely open honestly open, and make all of it something a stranger can walk up to and understand in thirty seconds — that's the standard every topic on here is held to.
In practice that's three different doors into the same subject, depending on how you want in. Quantum Playground is the fun one: ten interactive topics, each built to press and watch respond, no equations required to get the point. Quantum Lab is the deep end: the same ten topics as real, runnable math — build your own circuit, run the actual famous quantum protocols, tune the real equations behind each topic with sliders instead of trusting a canned animation. Pop Culture is the easy on-ramp: where quantum mechanics shows up (and gets mangled) in film, TV, and music, written for anyone who's never opened a physics textbook and isn't planning to.
None of that is dumbing anything down — it's the same physics at three different depths, so wherever you're starting from, there's a door that fits.
What's here
Five destinations, depending on what you're looking for.
Quantum Playground
The interactive build itself. Ten topics, each with its own hands-on demo and the physics underneath it — from a single particle in superposition to the unsolved clash between relativity and quantum mechanics.
Enter the playground → §Quantum Lab
Three hands-on labs: build your own circuit, run five famous quantum protocols, or explore any of the ten topics' equations live with sliders — all real computation, no canned animations.
Build an experiment → ≡Resources
The method, stated plainly, a technical appendix deriving the equations behind each topic, and every primary source this site's physics is checked against.
Read the method → ★Pop Culture
Twenty places quantum mechanics shows up (or gets mangled) in film and TV, plus a smaller, honestly-sized set of quantum-adjacent music.
Browse the list → @Contact
Found something inaccurate, want to talk about a collaboration, or just want to say hello.
Get in touch →Ten topics, three acts
The interactive build moves from the microscopic to the cosmic in three groups.
The Core Four
Four ideas that break classical intuition, and the foundation everything after them is built on.
Superposition · Measurement · Duality · Entanglement Group IIThe Weirdness Layer
What makes quantum mechanics genuinely strange, and where computer-science instincts start to help.
Uncertainty · Tunneling · Qubits · Cryptography Group IIIThe Big Questions
Where quantum mechanics meets the largest scales in the universe, and where physics runs out of answers.
Quantum Vacuum · Quantum GravityBuilt to a scientific standard, not a pop-science one.
Every claim on this site was checked against the primary literature, and every place the popular picture oversimplifies — Hawking radiation's "virtual particle pairs," "quantum foam" presented as settled physics — is called out explicitly rather than smoothed over. The full list of sources, and a note on method, is on the Resources page.
