About

CoursesHub.World — Free University-Level Science

CoursesHub.World is a free, open-access education platform for graduate-level courses in the natural sciences. The site offers rigorous treatments of physics, biology, chemistry, mathematics and earth sciences, built around derivations, interactive simulations, and links into the primary literature. Every course is free; nothing is gated, nothing is sold.

What makes the site different

  • Derivation-first. Course pages do not just state results — they derive them. Equations are typeset with MathJax, with full steps from first principles wherever possible.
  • Interactive widgets. Browser-side simulations (membrane potentials, signaling cascades, ODE integrators, 3D molecular structures via the RCSB Protein Data Bank) accompany the text where they help build intuition.
  • Cross-course coherence. Topics that appear across multiple disciplines (e.g., the TCA cycle in cell physiology / metabolism / cancer biology) cross-link consistently rather than re-explaining the same material.
  • Open and free. No accounts required to read; no advertising; no “premium” tier hidden behind a paywall.
