Physics of the Space Elevator with an Introduction to MATLAB — A Self-Study Textbook for New Members (in Japanese; PDF and MATLAB codes available here, English version is avaliable here

A 52-page self-contained textbook that takes complete beginners from MATLAB basics (up to ode45/ode15s) to space elevator physics — geostationary orbit, tether tension and taper design, payload release orbits, and tether dynamics — with a two-week self-study roadmap.
The capstone exercise builds a lumped-mass tether simulator reproducing the fundamental libration mode (±190 km tip oscillation, ~4.6-day period).
Prepared as an educational resource for SELECT (Space Elevator Challenge Tohoku); prerequisites are high-school mechanics and basic calculus only.
