Arabic is a Semitic language with a history spanning over 1,500 years, making it one of the world's oldest continuously spoken languages. It is the liturgical language of Islam and the official language of 26 countries across the Middle East and North Africa, spoken by approximately 400 million people as a native language and understood by hundreds of millions more. The Arabic script is written from right to left and consists of 28 consonants. Unlike Latin-based scripts, short vowels are not written as letters but as small diacritical marks placed above or below consonants — and in everyday writing, these marks are typically omitted entirely, leaving readers to infer pronunciation from context. Each consonant takes one of four different shapes depending on its position within a word: isolated, initial, medial, or final. Modern Standard Arabic (الفُصْحَى, al-fuṣḥā) is the formal written and broadcast standard used across the Arab world, derived directly from Classical Arabic — the language of the Quran. Alongside it exist dozens of regional dialects (العَامِّيَّة, al-ʿāmmiyya) that differ significantly in pronunciation and vocabulary, to the point where a Moroccan and an Iraqi speaker may struggle to understand each other in casual conversation. Arabic has had a profound influence on world languages. Spanish, Portuguese, Persian, Turkish, Urdu, Swahili, and many others have borrowed heavily from Arabic vocabulary — words like algebra (الجَبْر), algorithm (from al-Khwārizmī), cotton (قُطْن), coffee (قَهْوَة), and sugar (سُكَّر) all trace their origins to Arabic.

📐 Spacetime Diagram — A Minkowski diagram showing that time is the 4th dimension. Watch Alice (stationary) and Bob (moving at 0.5c) accumulate proper time τ at different rates in real time. 🔦 Light Cone — Drag the orange event point around the canvas. Hover anywhere to instantly classify that position as Future, Past, or Elsewhere. Nothing outside the cone can ever be reached without exceeding the speed of light. ⌚ Time Dilation — Push Bob's rocket speed up with the slider and watch the two clocks drift apart. The Lorentz factor γ updates live — and a reminder that GPS satellites correct for exactly this effect every single day. 🌀 Wormhole — Particles enter Mouth A in 2024 and exit Mouth B in 1924. A real-time visualisation of the Einstein–Rosen bridge and how curved spacetime can connect two different moments in time. 👴 Grandfather Paradox — What happens if you travel back and stop your grandfather? Click either choice and follow the logic to its conclusion — an infinite paradox loop versus the Novikov Self-Consistency Principle. 🌌 Many-Worlds — Every quantum decision splits the universe into parallel branches. Adjust the Split frequency slider to control how fast new timelines fork off, and watch the branching multiverse grow.

〰 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.

Derivative — The Slope tab Move the mouse along the curve to draw the tangent line (in red) at that point in real time A dashed secant line is shown alongside it, visually demonstrating the concept of a limit Shrink the gap between the two secant points using the Step h slider to watch it converge toward the tangent The slope angle and f′(x) value are displayed live Integral — The Area tab Drag the blue dot (a) to set the left boundary, then move the mouse to position the right boundary (b) The Riemann rectangles approximating the area are rendered step by step Increase the number of rectangles with the Rectangles slider to see the sum converge to the definite integral The ∫f(x)dx value is calculated in real time 6 available functions — sin(x), cos(x), x², x³, √x, and |x|. The absolute value function |x| is especially interesting: try hovering over x = 0 to experience a point where the derivative does not exist.
