The physics of the very small — from the first quantum ideas to the machines that will compute with them. Free, beginner-friendly, and available in English and Arabic.
Photons, wave–particle duality, the double-slit experiment, and why atoms don't collapse — the strangest theory in physics explained from zero. Real equations like E = hf with worked numeric examples, but no calculus anywhere.
Qubits, quantum gates, and the algorithms that could change computing forever. The natural next step after the Quantum Physics course — in preparation.
