QM Simulator vs Cosmivoy

QM Simulator is a hands-on quantum physics atlas: 54 interactive simulation modules spanning the full arc from quantum foundations to quantum information, paired with 47 bilingual articles. Every computation and rendering happens on your device — no network, no sign-up. WHAT YOU CAN DO • Play with parameters: adjust slit spacing, raise a potential barrier, tune cavity coupling — every chart recomputes in real time. • Learn by level: Basics → Advanced (perturbation, degeneracy, radiation) → Topics (Bell inequalities, quantum error correction, Grover's algorithm), from high-school extension to university QM. • Read linked notes: each article is tied to its simulation, with formulas and figures side by side — switch between Chinese and English anytime. • Explore freely: Bloch sphere, hydrogen wavefunctions, blackbody radiation, Compton scattering, Kronig–Penney, BB84 quantum key distribution — from Planck's 1900 hypothesis to today's quantum computing. WHO IT'S FOR • Physics students: turn textbook formulas into images you can see and manipulate. • Educators & researchers: validate intuitions and demonstrate in class. • The curious: no derivation skills needed — dial the parameters and build quantum intuition. HIGHLIGHTS • 54 simulation modules, all driven by real physics computation (not pre-baked animations). • 47 in-depth articles, fully bilingual, with figures and code. • Fully offline: no ads, no purchases, no tracking, no account required. • Chinese & English UI, follows system language. Educational use: QM Simulator works as a lecture-demonstration companion for quantum mechanics courses.

Explore the sky above you. Fly to the worlds beyond it. Cosmivoy turns your iPhone or iPad into a spaceship window. Discover the Solar System in 3D, travel from Earth to distant galaxies, and choose your own view of the universe. • See the sky from your location and look around by turning your device. • Warp between planets, orbit a moon, or land and explore a rocky world's surface. • Follow satellites and deep-space missions, including Webb and Voyager. • Pause, rewind and fast-forward time to explore orbits, sunrises and eclipses. • Zoom from a close-up to a 360° panorama. Switch between natural light and fill light to reveal surface details. • Read an offline encyclopedia and explore a catalog of more than 100,000 stars, Solar System bodies, galaxies and spacecraft. Core exploration works offline, without an account. Satellite orbit updates use an internet connection. Interface and encyclopedia available in 14 language options. No ads, subscriptions or in-app purchases.
