The Mathematical Inventions of Muhammad ibn Musa al-Khwarizmi

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

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
