读完这本书让我深深地感受到了中国科学家的无私奉献和不屈不挠的精神。许多中国科学家们为了追求科学真理，不断地去探索，他们在面对各种挑战时所表现出的勇气和毅力让我很敬佩，值得我们学习。
After reading this book, I deeply felt the selfless dedication and indomitable spirit of Chinese scientists. Many Chinese scientists constantly explore in pursuit of scientific truth. Their courage and perseverance in facing various challenges are admirable and worthy of our learning.
王泽山爷爷发明了很多火炸药，20世纪60年代，王泽山爷爷发现了火炸药的组成、结构性能的规律，建立了大炮、弹药、弹道学科融为一体，自此，他少年时的兴国强国梦正一步步实现，因此，王泽山爷爷被很多人称为“火炸药王”。
Grandpa Wang Zeshan invented many explosives. In the 1960s, Grandpa Wang Zeshan discovered the rules of composition and structural performance of explosives, and established the integration of artillery, ammunition, and ballistics. Since then, his dream of rejuvenating the country and building a strong nation in his youth has been gradually realized. Therefore, Grandpa Wang Zeshan is known as the "king of explosives" by many people.
吴明珠奶奶1949年考上了西南农学院果蔬专业，毕业后不久被调到了北京的中央农村工作部。从20世纪60年代开始，选育省级甜瓜、西瓜品种19个，推广面积达全疆80%。她是第一批献身中国边疆园艺事业的女科学家之一。
Grandma Wu Mingzhu was admitted to the Fruit and Vegetable major at Southwest Agricultural University in 1949, and shortly after graduation, she was transferred to the Central Rural Work Department in Beijing. Since the 1960s, 19 provincial-level melon and watermelon varieties have been selected and bred, with a promotion area of 80% in Xinjiang. She was one of the first female scientists to dedicate herself to the field of horticulture in China's border areas.
在疫情期间，也有像那些科学家们一样高尚品质的人。钟南山、李兰娟等院士他们始终坚守在抗疫的第一线。疫情高发期间，在如何做到安全复工复产时，钟南山爷爷建议：在电梯、餐厅、办公室等处，应该进行科学的消毒，外出或公共场所要佩戴口罩、保持距离，更主要勤洗手，室内要保持通风。在他们的努力下，疫情得到了有效控制，他们是我们值得敬重的“人民英雄”。
During the pandemic, there were also people with noble qualities like those scientists. Academicians such as Zhong Nanshan and Li Lanjuan have always been at the forefront of the fight against the epidemic. During the high incidence of the epidemic, Grandpa Zhong Nanshan suggested that scientific disinfection should be carried out in elevators, restaurants, offices, and other places to ensure safe resumption of work and production. Masks should be worn when going out or in public places, and distance should be maintained. It is important to wash hands frequently and maintain ventilation indoors. With their efforts, the epidemic has been effectively controlled, and they are our respected 'people's heroes'.
从这本里我学到了：遇到事情要坚持不懈、勇于探索。成功要靠自己的努力和付出，不能半途而废。
I learned from this book that when encountering things, one should persevere and be brave enough to explore. Success depends on one's own efforts and sacrifices, and cannot be given up halfway.
