Most Alestrius Lord Father, please send me back the next chapter of your draft. Here's the first one I am sending back, ready for you. I have made comments here and there, less those who know nothing of mathematics be confused. Ignorance of mathematics is a form of blindness. When reading, I feel as if I were hearing your voice. I miss your conversation and long to see you in person. Do you still believe that his holiness will be pleased if you write it as a dialogue? As the plague has returned, I pray that printing may not be delayed. From San Mateo, your most affectionate daughter, Sister Maria Celeste Galilei. The life of a nun offered many opportunities to advance a woman's education, making Sister Maria Celeste more educated than many of her contemporaries. Sister Maria Celeste acted as an editor for much of Galileo's writing. As the controversy of the comments was beginning to subside, Galileo began working on his dialogue on the two chief systems of the world. This text was written informally as a dialogue to make it more accessible to a wider audience. It outlines the different prevailing theories on astronomy, mechanics, including the signs of motion, and the physics of ocean tides.
