The latest book in the travel kit is Simon Singh’s Fermat’s Enigma, which talks about the mathematical knowledge that was in the library at Alexandria. It seems that the modern MP3 craze has ancient roots: “Even tourists to Alexandria could not escape the voracious appetite of the Library. Upon entering the city, their books were confiscated and taken to the scribes. The books were copied so that while the original was donated to the Library, a duplicate could graciously be given to the original owner.”
[The need for a good backup strategy also is highlighted by the travails of the old Library. In 47 BC part of the collection caught fire accidentally because Julius Caesar was out in the adjacent harbor burning Cleopatra’s ships. In AD 389 more books were destroyed because they were housed in the Temple of Serapis, a building that fell victim to a Christian assault on pagan monuments. Singh writes about the final destruction, which occurred after the Arab conquest of Egypt: “Then in 642 a Moslem attack succeeded where the Christians had failed. When asked what should be done with the Library, the victorious Caliph Omar commanded that those books that were contrary to the Koran should be destroyed. Furthermore, those books that conformed to the Koran were superfluous and they too must be destroyed. The manuscripts were used to stoke the furnaces which heated the public baths and Greek mathematics went up in smoke.”]
As I noted in my entry:

The destruction via Omar is best considered “an allegation”:

“…and Greek mathematics went up in smoke.”
Why Greek mathematics? Alexandria is in Egypt (Norhtern Africa)and everybody knows that the basis of mathematics and science was developed (discovered) in Egypt. The Greeks were students to the Egyptians for many centuries.
Statemments that include “everybody knows” are immediately suspect.
Kamau: According to Singh it was Pythagoras who came up with the idea of proof. People before him knew how to calculate a lot of stuff (and “geometry” literally means “measuring the Earth”) but weren’t interested in proving theorems. So that would make modern mathematics a Greek invention.
As for science, the scientific method wasn’t in widespread use until the Enlightenment, i.e., the late 16th century. Francis Bacon gets credit for being the first to articulate the idea so perhaps we should think of modern science as an English invention.
Seeing as Muhammad’s flight to Medina was in 712, the dates are impossible. The title caliph was adopted by Muhammad’s successors, so Omar could not have used it.
Hasan, the generally accepted date for the flight is 622 CE. More chronology here. The spread of Islam was pretty fast. Here is another page that puts the conquest of Egypt at 642 CE.
Also, Caliph Omar or Umar was extremely famous in Islamic history as the 2nd caliph and the conqueror of Jerusalem, one of the holy cities. (Especially celebrated by the Sunni, considering that the Shia did not acknowledge his legitimacy.) Islamic rules on how to treat Christians and Jews were pseudepigraphically attributed to him, via this document, The Pact of Umar, believed by many scholars to have been written at least two centuries later.
I know nothing about this library story, but the dates and people fit the ballpark pretty closely.
