"Discourses and Mathematical Demonstrations Relating to Two New Sciences" represents the summa of Galileo’s philosophical and physical theory, included by Stephen Hawking in the five most important books of all the history of science. This work led to Isaac Newton’s Principia and to experimental science. However, reading Galileo Galilei is not simple, but Alessandro De Angelis traslated the "Discourses and Mathematical Demonstrations Relating to Two New Science" for the common reader, and now Galileo’s legagy can be passed to future generations, helping them to understand one of the primary sources of scientific theory.
