Xiaohe stood before her classmates, eager to share stories of two genius scientists.She began with Tu Youyou, whose work in physiology saved millions of lives.In the 1970s, Tu aimed to defeat malaria.After encountering ancient texts, she insisted on studying wormwood.Through persistent experiments, she obtained a crucial extract using a low­temperature method to preserve its properties.This substance, later named artemisinin, became a vital treatment.“Her objective was clear，” Xiaohe said, “and she proved traditional medicine's power.”Next, Xiaohe talked about Albert Einstein.Though best known for relativity, Einstein once worked at a patent office, analysing devices.He earned his doctorate in 1905, the same year he drafted revolutionary

papers.Xiaohe explained how his theory redefined physics, inferring that energy and mass are linked.Despite difficult circumstances, his passion for science never faded.“He held a patent for a fridge design too！”Xiaohe added, highlighting his versatility.Both scientists, Xiaohe concluded, showed that curiosity and determination could change the world.
