ChemyLab vs Relativity Simulator

Step into the ultimate interactive chemistry playground! Chemy: The Visual Laboratory bridges the gap between abstract chemical symbols and tangible physical properties. Designed to build deep visual intuition, Chemy provides a state-of-the-art interactive periodic laboratory for students, educators, and science enthusiasts. Whether you want to visualize atomic structure, simulate thermodynamic states of matter, hear the sounds of light spectra, or build molecules in an interactive sandbox, Chemy brings the microscopic universe to life with premium visuals and responsive simulation mechanics. *** CORE INTERACTIVE MODULES & FEATURES *** INTERACTIVE PERIODIC TABLE (ATLAS) Explore the elements through an immersive, responsive catalog: • Dynamic Grid Layouts: Switch seamlessly between the Classic Periodic Table and the mathematically curved Curled-Ribbon Periodic Grid. • 3D Voxel Blocks: Toggle 3D voxel representations of elements, rendered with custom isometric projections. • Interactive Highlights: Color-code and filter the grid by Cosmic Nucleosynthesis Origin (Big Bang, massive stars, supernovae) or Chemical Families (Noble Gases, Alkali Metals, Halogens, etc.). • Deep Element Inspector: Dive into any element to inspect its scientific details: Bohr Card: Interactive Bohr model visualizer showing concentric electron shells and atomic properties. Electron Apartments: Maps complex quantum orbital configurations (s, p, d, f) to an intuitive apartment room layout filling dynamically based on Hund's Rule and the Aufbau principle. Quantum Forces: Visualize atomic grip forces (ionization energy and electronegativity) with dynamic vector lines. Spectral Signatures: View high-fidelity absorption and emission spectra. Auditory Spectra Synth: Synthesizes emission wavelengths into audible acoustic sine-wave frequencies. Listen to the unique sound of each element! REACTIONS CENTER & SANDBOX Experiment, balance, and build in an open-ended molecular lab: • Reaction Sandbox: A drag-and-drop chamber where atoms float freely. Collide elements to form covalent or ionic binary compounds (like H2O or NaCl) based on electronegativity delta, valency hook counts, and temperature. • Equation Balancer: Input chemical equations using a specialized Periodic Element Keyboard to calculate and balance stoichiometric coefficients instantly. • Molecular Structure Generator: Procedurally generate and inspect molecular stick-and-ball covalent bond structural diagrams. CHAMBER STATE SIMULATOR (SOLID, LIQUID, GAS) Understand how temperature affects atomic motion: • Global Thermal Controller: Simulate temperatures from absolute zero (0 K) up to 6000 K (the surface of the Sun) with key milestones like boiling and melting points. • Atomic Motion Physics Canvas: Watch a dynamic particle engine simulate atomic behavior. See solids locked in a crystalline lattice, cohesive liquids sliding at the base, and high-velocity gases colliding elastically. DENSITY COMPARER (MASS & VOLUME) Build physical intuition for how elements differ in weight and volume: • Isometric 3D Cube Comparison: Compare the density of two pure elements (e.g., 1 kg of Lead vs. 1 kg of Lithium) in dynamically scaling 3D cubes. • Buoyancy & Balance Simulator: Simulate water displacement and balance scales to visualize weight-to-volume relationships. MEMORIZATION TRAINER & PROGRESS • Gamified Quiz Loops: Master symbols, names, atomic numbers, and families with speed and accuracy feedback loops. • Element Sticker Book: Unlock elements in the sandbox to add glowing, starred stickers to your catalog. • Trophy Badges: Earn beautiful rewards (e.g., "Water Creator", "Metal Monarch").

Relativity Simulator is an interactive relativity toolkit built strictly on the axiomatic foundations of modern physics. There is no "hard sci-fi" here — every result traces back to the Lorentz transformation of special relativity or the Einstein field equations of general relativity, and is verified against numerical truth fixtures. 【Real physics, not imagination】 · 20 interactive modules covering core effects from special relativity to black holes, gravitational waves, and curved spacetime; · Each module ships with precise charts, adjustable parameters, and a "Theory Card" with a fully visible derivation chain; · All demo numbers are recomputed locally on your device from real CODATA constants — nothing is fabricated. 【Phenomena you can verify yourself】 · Gravitational time dilation: why clocks run faster up high — ~80 ns/day faster atop Everest, ~38 µs/day faster on GPS satellites; · Twin paradox: fly to 4.22 light-years at 0.8c and the Earth twin ages 10.5 years while the traveler ages only 6.3; · Tidal disruption: why you get stretched into "spaghetti" falling into a black hole — small holes tear you outside the horizon, supermassive ones only after you cross it; · Plus light bending, gravitational lensing, the Schwarzschild horizon, frame dragging, and mass–energy equivalence E=mc². 【Built for learning and teaching】 · Volume-based progression: kinematics → gravitational field → black holes → cosmology → applications; · Bilingual (zh/en) system notes ship with every effect: derivation, physical quantities, and references; · Chinese / English UI follows your system language. 【Privacy first】 The app collects, stores, and transmits no personal data, embeds no third-party SDKs, and runs every computation locally on your device. Whether you are studying, teaching, or simply curious, Relativity Simulator lets you actually run the "invisible spacetime" and watch it.
