'''Roger Bacon''' (Doctor Mirabilis) (Ilchester, ca. 1220 - Oxford, 1292) was a great English [[friar]] and [[philosopher]] who wrote an [[encyclopedia]], his ''Opus Majus''. He is hailed by many the father of modern [[science]]. His focus on [[empirical]] approaches to science was influential. Among other things, he wrote about [[mathematics]], [[alchemy]], the positions and sizes of celestial bodies, envisioned the possibility of spectacles, [[microscope]]s, [[telescope]]s, flying machines, steam ships and explosives, recognized the [[visible spectrum]] in a glass of water centuries before [[Isaac Newton]] worked on optics, and observed [[solar eclipse]]s through a camera obscura.

He urged [[theologians]] to study the sciences and add them to the [[university]] curriculum. He rejected the blind following of prior authorities, both in theological and scientific study.

''If we now examine Bacon's scientific systems and leading principles, his aims and his hobby, so to say, we find that the burden not only of the writings sent to the pope, but also of all his writings was: ecclesiastical study must be reformed.''
