How Five AI Personas Explain Newton’s Gravity in Five Distinct Ways

Tao Zhexuan and collaborators built five LLM‑driven chatbots with different fictional personalities, asked each to describe Newton’s law of universal gravitation, and found wildly varied explanations that illustrate both the novelty and the potential teaching value of persona‑based AI assistants.
