What did Galileo say were the letters of Mathematical languagey
Galileo Galilei, an Italian astronomer and mathematician, did not explicitly mention the "letters of Mathematical language" in his works. However, he did emphasize the importance of mathematics as the language of nature and the universe. He famously stated that the book of nature is written in mathematical language.
To gain a more comprehensive understanding of Galileo's views on mathematics and its role in explaining natural phenomena, I would recommend exploring his various works, particularly his two influential books: "Dialogues Concerning Two New Sciences" and "The Assayer." These texts delve into Galileo's discoveries, scientific methodology, and ideas related to mathematical reasoning.
