DynaPhysics vs Sapling Isle

DynaPhysics 是一款面向高中物理学习与课堂演示的交互式可视化应用。它将抽象的公式、规律和物理模型转换为可调参数、可实时反馈的动态演示，让学生更直观地理解物理本质，也让教师在讲解中更高效、更生动。应用目前涵盖光学、电磁学、热学、简谐振动等多个核心模块，支持实时交互、参数调节、图像观察与规律理解，适合课堂展示、课后复习和自主探索。

Sapling Isle is a multilingual interactive science lab that connects observable phenomena with advanced scientific concepts on iPhone and iPad. Change variables directly, observe how a system responds, read graphs and measurements, then explore the equations, assumptions, and limits behind the model. Explore nature and the universe • Control a 3D Solar System and observe planetary motion and astronomical time • Follow curved light, an accretion disk, and Einstein rings around a black hole Enter a hands-on physics lab • Explore forces, motion, heat, energy, magnetic fields, light, and atoms • Compare heating, compression, and diffusion in a 3D microscopic world • Investigate orbits, waves, entropy, Boltzmann distributions, quantum tunneling, and double-slit patterns Explore at your own depth • Start with direct manipulation and visual feedback • Continue with multivariable comparisons, measurements, and graphs • Go deeper into equations, approximations, and model boundaries • Choose from 10 interface languages • Adaptive layouts for both iPhone and iPad • No account, advertising, or cross-app tracking • Progress, camera frames, and experiment data are handled primarily on device Pick an island, begin with a phenomenon, and follow the evidence toward deeper models.
