After Galileo had completed work on the Discourses it was smuggled out of Italy, and taken to Leyden in Holland where it was published. It was his most rigorous mathematical work which treated problems on impetus, moments, and centres of gravity.
Pagkatapos ng Galileo ay natapos na trabaho sa Discourses ito ay kontrabando ng Italya, at dadalhin sa Leyden sa Holland kung saan ito ay nai-publish. Ito ay ang kanyang pinaka-mahigpit na matematiko trabaho na kung saan ginagamot problema sa puwersa, sandali, at mga sentro ng gravity.
