Acknowledgment of Inspiration

I would like to sincerely thank the following websites for their inspiration and influence in the development of the 3JCN Physics Simulation platform:

  • Threejs.org: For providing the powerful 3D graphics engine that makes interactive, browser-based simulations possible.
  • PhET Interactive Simulations – University of Colorado Boulder: For setting the gold standard in science education tools that are both engaging and effective.
  • Physics Simulation – Boston University: For its clean and thoughtful visualizations of core physics concepts.
  • Magnet Academy – National High Magnetic Field Laboratory: For their creative and accessible approach to explaining magnetic concepts.
  • oPhysics: For its clear, educational applets that have long supported physics learners.

Their work continues to inspire my own efforts in creating free and meaningful educational tools for students and teachers around the world.
