Roger Bacon describes principles of a camera obscura that can project pictures. He bases his optics (and other ideas) on what he has learned from writings by the early 11th century Arab philosopher Abu Ali al-Hasan ibn al-Haytham, who said that no mathematical theory or conjecture was necessary to realize that light starts outside the eye and reflects into it and that looking directly at the sun or some other bright object will burn the eye (see Porta, 1553).
Nonfiction: Opus Majus by Roger Bacon, who describes the magnetic needle of a compass and reading glasses (see 1249). "Argument . . . does not remove doubt," he writes, "so that the mind may rest in the sure knowledge of the truth, unless it finds it by the method of experiment . . . For if any man who never saw fire proved by satisfactory arguments that fire burns . . . his hearer's mind would never be satisfied, nor would he avoid the fire until he put his hand in it . . . that he might learn by experiment what argument taught." The first truly modern scientist (he is known as "Dr. Mirabilis"), Bacon predicts radiology and predicts also the discovery of the Western Hemisphere, the steamship, the airplane, and television (see 1277; portolan chart, 1311).

Culture
- Roger Bacon completes his work Opus Majus and sends it to Pope Clement IV, who had requested it be written; the work contains wide-ranging discussion of mathematics, optics, alchemy, astronomy, astrology, and other topics, and includes what some believe to be the first description of a magnifying glass. Bacon also completes Opus Minus, a summary of Opus Majus, later in the same year. The only source for his date of birth is his statement in the Opus Tertium, written in 1267, that "forty years have passed since I first learned the alphabet". The 1214 birth date assumes he was not being literal, and meant 40 years had passed since he matriculated at Oxford at the age of 13. If he had been literal, his birth date was more likely to have been around 1220.
