I'm Geo Wang, a Mathematics student at NYU. I love building tools that solve real-world problems, and I develop, maintain and publish open-source Android apps for the F-Droid ecosystem.
Beyond coding, I have a strong inclination towards traditional Chinese poetry (see my poems) and I'm a disciple of Friedrich Hayek and the Austrian school of economics (see my blog).

Kinematic Analysis of Elytra Flight as a Discrete Dynamical System: Energy Injection and Perpetual Motion in Minecraft Physics
Modeled Minecraft's Elytra flight as a 20 Hz discrete dynamical system and derived closed-form fixed points for both gliding and climbing. Proved analytically that θ = 0° is the globally optimal pitch, with an exact asymptotic glide ratio of 495/49 ≈ 10.102 : 1, and showed global linear convergence (ρ = 0.99) via the Jacobian's eigenvalues. Asymmetric momentum-transfer coefficients reveal a net energy-injection mechanism worth +3.66 blocks of height per cycle.
