The Mathematical Inventions of Muhammad ibn Musa al-Khwarizmi


The mathematical concept of algorithms were developed by and subsequently named after Muhammad ibn Musa al-Khwarizmi (pronounced “moo-ham-mad ih-bin moo-sah al kwar-iz-me”), an Islamic scholar who lived during the 8th century. The concept of algorithms arrived in Europe in the 12th century and al-Khwarizmi’s name was translated to Latin which is where the term “algorithm” is derived. al-Khwarizmi also introduced the western world to the decimal system and introduced reduction and balancing methods (e.g. like and unlike terms) causing al-Khwarizmi to become referred to as the ”father and founder of algebra”. The term “algebra” is derived from the Arabic term “al-jabr” which means “reunion of broken parts”. al-Khwarizmi invented and used algebra to solve quadratic equations and it has been stated throughout history that the ideas that al-Khwarizmi developed, helped usher in the European Renaissance during the 14th, 15th, and 16th centuries

Robert Goddard’s Liquid Fueled Rocket Concept


Robert Goddard devised the idea of liquid kerosene and liquid oxygen being mixed together to create a fierce, but most importantly, a controllable flame for propulsion. When kerosine reacts with oxygen, the result is an incredibly hot, rapidly expanding gas which when channeled through a nozzle, creates enormous thrust. On March 16, 1926, Goddard launched the world’s first liquid fuel rocket bearing this concept. This rocket did not travel fast nor far but it did demonstrate a proof of concept making space flight theoretically possible for the first time in human history
