墨子和他的墨家学派是一个科学家团体,他们在数学、物理学、医学、逻辑学等方面都有杰出的贡献。墨子还精通手工技艺,可与当时的巧匠公输般(即鲁班)相媲美。墨子很擅长防守城池,据说他制作守城器械的本领比公输般还要高明。墨子非常反对为了争城夺地而使百姓遭受灾难的混战。一次他听到楚国要利用公输般发明的云梯去侵略宋国,就急急忙忙地亲自跑到楚国的都城郢(Ying)都,劝公输般不要帮助楚惠王攻打宋国。 Mozi and his Mohist School are a group of scientists who have made outstanding contributions in mathematics, physics, medicine and logic. Mozi also proficient in manual techniques, comparable with the then craftsman public transport (that is, Luban). Mozi is good at defending the city, and he is said to be more adept at defending the defensive equipment than the public transport. Mozi very much opposed melee to win the battle for the city. Once he heard that the State of Chu wanted to use the public transport-like ladder to invade the Song State, he hurriedly went to the capital of the capital of Chu to persuade the public to lose the war against Chu Hui Wang.
