Roger bacon's date of birth is uncertain. He wrote in 1267 that it has been 40 years since I first came into contact with the alphabet, and it is certain that I entered Oxford at the age of 13. So the researcher assumes that he didn't know the alphabet before he entered Oxford University, so it can be inferred that his date of birth is 12 14. Otherwise, his birth time should be around 1220. Bacon's American family was relatively rich, but in Henry III, many of his family members were robbed of American property and some were exiled.
There is no evidence that Bacon received a doctorate from Oxford University, but he worked as a teacher in Oxford and taught Aristotle's thoughts. 14 1 year, went to teach at the University of Paris, France. From 65438 to 0947, he returned to Oxford University, bought many books and instruments, declined social and academic activities and started his own research. He joined the Franciscans around 1253.
Bacon's scientific education in the United States and his own research made him see many defects in the academic debate at that time: no teachers knew Greek, which made them understand Aristotle's thoughts and could only be expressed through poor translation. Physics is not learned by experiments as Aristotle suggested, but by debating classics.
Bacon, who witnessed all this, opposed this empty argument and advocated the importance of experiment. Moreover, because of his straightforward personality, he preached what he thought was right and criticized what he disagreed with, which brought him a lot of trouble. 1256, Richard of Cornwall, whom Bacon had been attacking, became the leader of Franciscans in England. Soon, Bacon was transferred to a monastery in France. Ten years later, he can only communicate with his friends by writing letters.
Bacon wrote to Gifford Legro. Legro was interested in Bacon and hoped that he could provide a detailed paper. Bacon hesitated about this request, because it was stipulated that Franciscans were not allowed to spread their works outside the meeting without permission. After GuiFaucoile Gro taught the priest, he ignored the regulations and encouraged Bacon to secretly write a book for him.
Bacon wrote a masterpiece involving rhetoric, logic, mathematics, physics and philosophy, and gave it to the Pope on 1267. In the same year, he continued to write abstracts of big works and small works. 1268, in order to prevent the loss of the first two works, he wrote a short comprehensive version of the third one and sent it to Clemens IV.
This book covers all kinds of science and technology at that time and really expounds the methods of scientific research. But bacon did not elaborate on every topic, but wrote an outline, which was later expanded. Unfortunately, the Pope died in 1268 and didn't read this book.
Bacon, 1278, spread alchemy in the Arab world. He was placed under house arrest by Franciscans for more than ten years and died shortly after he was released from prison.
