Notably, it is also believed that rockets were brought to Europe during the 13th century and heavily improved by various intelligent scientists and inventors (“The History of Rocket Science”). With this in mind, Roger Bacon improved the ideas of rockets by developing a more powerful gunpowder which consisted of 75% saltpetre, 15% carbon, and 10% sulfur (“The History of Rocket Science”). In Addition, Jean Froissant added a launch pad for most efficient and accurate results when launching results and aiming them (“The History of Rocket Science”). Also, in Poland there was many experimentations with rockets and staging: multi stage rockets have different parts which have their own engine and propellant (“The History of Rocket Science”). With different parts, the rocket can empty it's fuel out as it accelerates or ascends and decreases the amount of mass on the remaining body of the rocket in total (“The History of Rocket
