'''Roger Bacon''' 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.

Bacon urged the reform of theological study, emphasizing the study of the [[Bible]] in its original source languages and decrying the corruption of scriptural texts and the works of [[Greek philosophers]] by mistranslations and misunderstandings. 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.
