VSEPR Molecular Geometry
Explore 3D molecular geometries for common electron-domain configurations. Rotate and inspect tetrahedral, trigonal planar, linear, octahedral, and bent structures. Understand how lone pairs distort ideal bond angles.
Thin Lens Equation Simulator
Construct dynamic ray diagrams for converging and diverging lenses. Analyze real/virtual image formation using the thin lens equation and magnification formulas.
Quantum Bohr Model
Visualize electron orbital transitions in Hydrogen-like atoms. Calculate photon emission wavelengths and generate real-time spectral lines (Lyman, Balmer, Paschen).
Doppler Effect 2D
Simulate sound wave propagation from a moving source. Calculate perceived frequencies for front and rear observers, and explore the Mach Cone (sonic boom) during supersonic flight.
Entropy in Heat Engines
Visualize the 2nd Law of Thermodynamics. Build reversible Carnot engines and irreversible real engines to track the exact entropy changes in the hot reservoir, cold reservoir, and the universe.
Chi-Square Goodness of Fit
Calculate and visualize deviations from expected categorical frequencies. Generates the exact right-skewed Chi-Square distribution and P-Value tail.
t-Distribution vs Normal
Examine the heavy-tailed Student's t-distribution. Increase degrees of freedom (df) to watch it perfectly converge into the standard normal z-distribution.
Sampling Distributions (CLT)
Struggle with the Central Limit Theorem? Draw 10,000 samples from highly skewed or bimodal parent populations and watch the perfect normal bell curve emerge.
Residual Plots
Evaluate the appropriateness of Least Squares Regression Lines (LSRL). Detect curvilinear patterns, heteroscedasticity, and influential outliers.
Sorting Algorithms O(N^2) vs O(N log N)
Visualize Selection, Insertion, and Merge sort line-by-line. Track memory accesses, array swaps, and Big-O efficiency in real time.
Array vs ArrayList Memory Resizing
Witness the internal array backing an ArrayList dynamically resize. Compare fixed memory bounds against O(N) copy operations when capacity is exceeded.
2D Array Traversal
Deconstruct nested loops covering Row-Major, Column-Major, and boundary tracing across a 2D integer matrix.
