通过提出问题“F=ma 是谁写的?”，研究了1638 年到1960 年的部分物理学原著、人物传记、大学物理教材、中学物 理课本、国际会议记录等材料，对物理符号的历史演变进行梳理，归纳出其经历了从几何图形到数学符号，再到物理符号，并 最终建立国际单位制(SI)符号的发展历程.

By asking a question"who wrote F =ma?" the materials from 1638 to 1960 (including physics original works,biographies,physics textbooks in college and secondary school and reports of international conferences,etc) are discussed,the development of physics symbols is reviewed£® This history is summarized into four stages (geometry,mathematic symbol,physics symbol and SI symbol)
