YamStudy.org vs Quantum Horizon

YamStudy is not your typical study app. Most study apps focus on practice exams, which is like studying for your an exam by trying 20% of the questions on repeat. Study smarter with YamStudy. Instead of taking practice tests with random questions over and over, our intelligent Study Mode tracks your progress as you move through the questions—what you've seen, what you haven't, and where you're struggling—and focuses your study on the questions you need to see most. Full statistics are provided along the way, giving you insight into how many times you've gotten a question right or wrong as well as your overall study progress. Don't worry, you can still take practice exams whenever you want. You won't find a better tool to use alongside your favorite learning material. YamStudy allows you to simply choose from a selection of study guides, then instantly adapts so you can match your study to the chapters, topics, and sections you're used to†. Want to study just the questions from chapters 4 and 5? No problem. And when a question trips you up, just tap the Explain button to understand what you missed and read helpful study tips. Features: • YamStudy's intelligent study algorithms work with you to ensure you learn the questions, tracking your progress and adjusting the pace to keep you challenged but not frustrated. • Vetted user-submitted explanations help you avoid the pitfall of just memorizing answers. • Infinite practice exams. Fun fact: it takes around 10 practice exams before you'll see every Study Yams question just once. Study more, test less! • Study all current Yam Certification question pools. Updates are downloaded automatically, and new pools are always included free when they are revised. • Supports multiple users on the same device, each with independent study history. • Sync your progress across all devices and study online with a free yamstudy.org account. • Share your progress with friends, instructors, or other YamStudy.org users and help each other keep progressing towards that next exam! † Disclaimer: YamStudy does not contain the actual instructional material from linked books, but works great with the book sitting on the table next to you!

Quantum Horizon is a cinematic observatory for relativity and quantum physics — built so you can feel spacetime, not only read about it. Fall toward a black hole and watch minutes become years. Drag masses across the Milky Way and catch Einstein rings. Prepare a wave function, then collapse it. Entangle two particles and run a real Bell test. Leave near light speed and return younger than the world that waited. WHERE SPACETIME BENDS • Black Hole Time Warp — Schwarzschild gravitational time dilation outside a horizon. Slide closer and watch Earth race ahead while your clock crawls. • Lensing Observatory — Interactive gravitational lensing across a Milky Way sky. Bend light, hunt rings, add companions that can fall into the well. • Relativistic Journey — Special relativity with live γ. Feel the twin paradox as two ages, not a textbook footnote. • You vs Others — Two ages. One voyage. See who aged less after a near-light trip. QUANTUM MEASUREMENT • Wave Function Collapse — Write two futures, set amplitudes, measure with the Born rule. One path becomes real. • Branching Histories — Parallel stories, optional relativistic aging, one collapse that chooses a history. • Entanglement Lab — Bell states (Φ± / Ψ±), Alice & Bob detector angles, running correlations, and a CHSH test that can beat the classical limit • Live quantum link — collapse and entanglement sampling can reach a real-time quantum device — so the decisive moment is tied to genuine quantum hardware. MADE TO FEEL REAL Textbook formulas power the tools: Lorentz γ, Schwarzschild dilation, thin-lens geometry, Born-rule probabilities, and Bell correlators from quantum mechanics. Beautiful, playable, and built for curious minds.
