Neuro Sandbox vs Quantum Horizon

Neuro Sandbox is an interactive visual sandbox for exploring neural network dynamics. Build small networks by placing neurons, connecting synapses, and observing how activity flows through the system in real time. Neuro Sandbox is designed for students, researchers, and anyone interested in computational neuroscience who wants to see how network behavior emerges from simple rules. Rather than writing code, you interact directly with the network. Adjust parameters, introduce feedback loops, and watch how excitation, inhibition, and decay shape firing patterns over time. What you can do: • Build custom neural networks by adding and connecting neurons • Assign excitatory or inhibitory neuron types • Adjust basal firing rates and synaptic decay • Modify synaptic weights and observe their effects • Visualize spike propagation and firing dynamics • Monitor live firing rates and recent activity history • Explore simple Hebbian-style learning rules • Detect and pause runaway network behavior

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.
