Margalit Fox, "The Riddle of the Labyrinth" | Talks At Google
 
56:26
THE RIDDLE OF THE LABYRINTH, by New York Times writer Margalit Fox, tells one of the most intriguing stories in the history of language—the race to decipher the Bronze Age script known as Linear B, first dug up on clay tablets in Crete in 1900. Fox masterfully blends history, linguistics, and cryptology into a mesmerizing account that reads like an intellectual detective story. At the center of this narrative is an American linguist, Alice Kober, whose major contribution to the decoding of the script is unknown to history because she died before she was able to make the final leap. In many respects, Alice Kober is to the story of Linear B what Rosalind Franklin, the great unsung heroine of the mapping of molecular structure of DNA, is to that canonical Margalit Fox holds graduate degrees in linguists and currently has been writing obits for the NYT, many of which have been front page.

07:36
20+ Great Inventions and Innovations by Muslim Scientists Here is list of 20 greatest inventions and innovations of Muslim scientists. From vaccination to surgery and from parachute to windmill, the Muslims have given the world many innovations that we take for granted in daily life. Here is list of 20 great inventions of Muslim scientists. PINHOLE CAMERA Muslim mathematician, astronomer and physicist Ibn al-Haitham invented the first pinhole camera in 10th century. ALGEBRA, TRIGONOMETRY AND NUMBERING SYSTEM Algebra was named after al-Khwarizmi's book, Al-Jabr wa-al-Muqabilah, much of whose contents are still in use. The work of Muslim mathematicians was imported into Europe 300 years later. Algorithms, trigonometry, cryptology and writing style of numerals also came from the Muslim world. SURGICAL INSTRUMENTS Many modern surgical instruments are of exactly the same design as those devised in the 10th century by a Muslim surgeon called Al-Zahrawi. In the 13th century, a Muslim medic named Ibn Nafis described the circulation of the blood, 300 years before William Harvey discovered it. Muslims doctors also invented anesthetics. PARACHUTE A thousand years before the Wright brothers a Muslim astronomer and engineer named Abbas ibn Firnas made several attempts to construct a flying machine. Though he was not fully successful in flying but had given the concept of airplane and parachute. SHAMPOO AND SOAP Soap and shampoo was invented by Arab Muslims. MINERAL WATER AND PERFUME Jabir ibn Hayyan was a great Muslim chemist in 8th century. He invented many basic processes and apparatuses of chemistry which are still in use. He invented the perfume and pure water through distillation, filtration, evaporation and purification process. CRANKSHAFT Crank-shaft was created by a Muslim engineer Al-Jazari to raise water for irrigation. He also invented or refined the use of valves and pistons, devised some of the first mechanical clocks driven by water and weights, combination lock, and was the father of robotics. ARCHITECTURAL INVENTIONS Pointed arch, castle building, dome building technique and watch towers was made by Muslim architects. Architect of Henry V's castle was a Muslim. WINDMILL The windmill was invented in 634 for a Persian caliph and was used to grind corn and draw up water for irrigation. It was 500 years before the first windmill was seen in Europe. VACCINATION Children in Turkey were vaccinated at least 50 years before the West discovered it. FOUNTAIN PEN The fountain pen was invented for the Sultan of Egypt in 953 after he demanded a pen which would not stain his hands or clothes. COFFEE Coffee was originated from Kaffa, Ethiopia. By the late 15th century it had arrived in Mecca and Turkey from where it made its way to Venice in 1645. It was brought to England in 1650 by a Turk who opened the first coffee house in London. The Arabic qahwa became the Turkish kahve then the Italian caffé and then English coffee. THREE-COURSE MEAL Ali ibn Nafi Ziryab came from Iraq to Cordoba in the 9th century and brought with him the concept of the three-course meal - soup, followed by fish or meat, then fruit and nuts. GLASSWARE Ali ibn Nafi Ziryab also introduced crystal glasses which had been invented after experiments with rock crystal by Abbas ibn Firnas. DEGREE AWARDING UNIVERSITIES The first formal university was Al-Karaouine, founded in 859 by Fatima al-Fihri in Fes, Morocco. Upon the successful completion of course, this university granted them a certificate known as an “Ijaza”. Al-Azhar University was founded in Cairo (Egypt) in 970, and in the 1000s, dozens of universities were established throughout the Middle East. The concept of institutes that grant certificates of completion (degrees) spread into Europe through Muslim Spain, where European students would travel to study. The Universities of Bologna in Italy and Oxford in England were founded in the 11th and 12th centuries and continued the Muslim tradition of granting degrees to students. CARPETS Origin of carpets is Iran and nearby Muslim countries. CHEQUE The modern cheque comes from the Arabic saqq. In the 9th century, a Muslim businessman could cash a cheque in China drawn on his bank in Baghdad. SHAPE OF EARTH 500 years before Galileo, Muslim scholars revealed the truth that earth is spherical. They also calculated the circumference of the earth. ROCKET AND TORPEDO By the 15th century Muslims had invented both a rocket and a torpedo, and were being used by their militaries. CHESS Chess, into the form we know it today, was developed in Persia. From there it spread to Europe. Click here to read complete interesting story of Chess. GARDENS Muslims developed the idea of the garden as a place of beauty and meditation. The first royal pleasure gardens in Europe were opened in 11th-century Muslim Spain.
