History of science in the 13th century
13th century: The spinning wheel is brought to Europe (probably from India). "Mathematical Renaissance" in China.
1202: Leonardo of Pisa introduces Hindu-Arabic numerals to Europe with his book Liber Abaci.
1204, December 13th: Maimonides / RAMBAM dies.
1210: Roger Bacon born.
1238: Yang Hui born (invents his version of Pascal's triangle - later important for statistics)
1240: Bartholomeus de Glanvilla concludes De proprietatibus rerum. The most widely read and quoted encyclopedia in the late-medieval period.
1250: Fibonacci dies.
1253: Robert Grosseteste dies. He introduced a kind of scientific thought.
1260: Vincent of Beauvais concludes Speculum Majus. The most ambitious encyclopedia in the late-medieval period over 3 million words.
1261: Qin Jiushao, who introduced the 0 to China, dies.
~1270: Paper manufacture begins in Italy.
1274: Nasir al-Din Tusi (said to be most eminent astronomer between Ptolemy and Copernicus; also established trigonometry as independent science) dies.
1277: A treaty between the crusader Bohemond VII, titular prince of Antioch and the Doge of Venice for the transfer of glassmaking technology isn't signed, so the transfer of Syrian glassworkers and their trade secrets doesn't happen. The famous Venetian glass industry isn't born.
late 1280s: Eyeglasses are invented in Italy.
1285: William of Ockham born.
General state of the art:
Western Europe: The "12th century Renaissance" has already started, with men like Albertus Magnus, Thomas Aquinas, Roger Bacon. Scholastics. The nominalists (those who believe that Plato's "ideal entities" are just names, but not the real things) slowly win over the "realists" (those who support Plato).
Islamic World: Algebra, Non-Euclidean geometry. Lots of knowledge about Optics, f.e. refraction. Also good in mechanics.
India: Also many ideas in mathematics and physics - including ideas for an atomic theory, law of gravity, and a heliocentric system. Geometry, trigonometry, binary system, floating point operations, even calculus.
China: Lots of mathematics, f.e. about solving of equations of higher grades, the Rule of Three and matrix methods for linear equations. First law of motion.

General summary of the 13th century:
Mongols:
Temujin (who isn't called Genghiz yet) dies early in 1200. The Mongols and other steppe people fall apart, fight among themselves instead. Temujin's son Ogadai manages to unite them for a second time, fights the Kara-Kitai, the Tangutes / Hsi-Hsia and even challenges the Choresmians, who still are victorious under their Shah Jalal-ad-Din. After Ogadai's death, the steppe people fall apart again.
East Asia:
Hsi-Hsia are eventually conquered by the Jin. Song China has to struggle with internal problems and loses a border war against Pagan. Khilji dynasty comes to power in Delhi.
Muslim world:
Choresm conquers Baghdad, makes the Caliph its puppet, extends its influence down to the Mediterranean. The Shiites stay stronger. Assassins survive. Rum-Seljuks kick out Byzantium / Nikaia from Asia Minor. Mamluks come to power in Egypt, conquer crusader states in Palestine.
Eastern Europe:
Hungary controls Bosnia, Serbia and OTL Romania. Volga Hungarians go to Hungary proper, convert to Christianity. Bulgaria stays more stable. Nikaia can reconquer Constantinople eventually, but has to agree on a union of the churches, and is dangerously weakened. Teutonic Order subjugates Prussians earlier, conquers Lithuania. Vladimir-Suzdal expands at the expense of Volga Bulgarians. Kara-Kitai attack the Kumans, but the latter under Baibars can defend successfully.
Western Europe:
Poland is (mostly) reunited, a new king is crowned. Hungary expands into Austria for short time, but is beaten back by Otakar Przemysl, who doesn't inherit Bohemia ITTL, but can keep Austria in the family and is elected king of the HRE. The Przemyslid lands are split between two lines of succession. Other than that, no changes.
America, Oceania, sub-Saharan Africa:
No changes.
