Scientific method is a body of techniques for investigating phenomena, acquiring new knowledge, or correcting and integrating previous knowledge. To be termed scientific, a method of inquiry must be based on empirical and measurable evidence subject to specific principles of reasoning. In 1021 CE, Ibn al-Haytham introduces the experimental method and combines observations, experiments and rational arguments in his Book of Optics. There are five major steps in the scientific method: Observe, Hypothesize, Predict, Experiment and Reproduce.
