〰 Double-Slit — Slide the Observe control from 0 to 1 and watch the interference pattern vanish, replaced by a classical particle distribution. See for yourself how the act of measurement changes the outcome. ⟨ψ⟩ Superposition — The rotating arrow on the Bloch sphere represents the superposed state. Click it to collapse the wave function — the qubit will randomly resolve to either |0⟩ or |1⟩ according to its probability amplitudes. Δ Uncertainty Principle — Narrow the position spread Δx with the slider and the momentum spread Δp widens in response. The product Δx·Δp ≥ ħ/2 is enforced at all times, shown live. 🚧 Quantum Tunnelling — Even when a particle's energy E is lower than the barrier height V, some particles pass straight through. The theoretical tunnel probability and the observed pass rate are displayed side by side. 🔗 Entanglement — Set different measurement angles for Alice and Bob, then click to measure both particles simultaneously. The quantum correlation between their outcomes is visualised in real time as the angle difference changes.

🌌 Gravity Well — Hold the mouse button to spawn a second gravity source and watch particles shift their orbits. A real-time visualisation of Newton's Law of Universal Gravitation. 🔵 Double Pendulum — Two pendulums starting from nearly identical conditions trace completely different paths over time. An intuitive demonstration of the Butterfly Effect at the heart of chaos theory. 〰️ Wave Interference — Renders constructive and destructive interference patterns from two wave sources in real time. Drag either source to reposition it. 🪨 Sand Pile — Click and drag to pour sand and watch the Angle of Repose form naturally as grains settle into a self-organised slope. ✨ Lissajous Curve — Adjust the X/Y frequency ratio and phase to draw circles, figure-eights, pretzels, and more. The same principle behind oscilloscope waveform analysis. 🧲 Magnetic Field — Drag the N/S poles to new positions and watch the field lines instantly reform around them.

The periodic table, also known as the periodic table of the elements, is an ordered arrangement of the chemical elements into rows ("periods") and columns ("groups"). https://en.wikipedia.org/wiki/Periodic_table

주기율표(週期律表, 영어: periodic table) 또는 원소 주기율표는 화학 원소를 가로줄("주기")과 세로줄("족")로 정렬한 표이다.[1] 화학의 상징이자 물리학 및 기타 과학 분야에서도 널리 사용된다. https://ko.wikipedia.org/wiki/주기율표
