Three Musketeers: Sherlock Holmes, Mathematics and Python
summary
Shows concrete forensic computations: shoeprint pressure computed with P = m g / A from measured depth and contact area, fall-distance angle thresholds that separate accident suicide and murder (examples near 0°, small launch angles, or ~28–38°), diagonal fit via Pythagoras (briefcase diagonal ≈ 25.6" vs 24" artifact), visual resolution limit 0.0003 radians that invalidates a 200 m / 4 cm witness claim, statistical anomaly detection using Benford's law (leading digit 1 ≈ 30%), and Python tooling (NumPy SciPy Matplotlib pandas benford package hashing and logging) to make analyses reproducible.
