In the Company of Scholars Lecture Series: "Circa 1000"


source: Yale University     2015年1月13日
Valerie Hansen, Mary Miller, and Anders Winroth discuss the world in the year 1000, when the different regions of the world participated in complex networks. Archaeological excavations reveal that the Vikings reached L'Anse aux Meadows, Canada, at roughly the same time that the Kitan people defeated China's Song dynasty and established a powerful empire stretching across the grasslands of Eurasia. Viking chieftains donned Chinese silks while Chinese princesses treasured
Baltic amber among their jewelry. In what is now the American Southwest, the people of Chaco Canyon feasted on tropical chocolate, while the lords of Chichen Itza wore New Mexican turquoise—yet never knew the Huari lords of the central Andes. Islamic armies conquered territory in western China (modern Xinjiang).

Patrick Vieira join us at Google's New York City campus to discuss his current role as head coach of New York City FC and share stories from his legendary football career.
Over the course of his glittering 17-year playing career Patrick Vieira represented Cannes, Milan, Arsenal, Juventus, Inter and Manchester City. Vieira’s illustrious time on the pitch as a player saw him lift five FA Cups, two Suppercoppas, and seven league titles. He was the legendary captain of Arsenal during its 2003-04 unbeaten season. In international play, his 107 caps for France include winning performances in the 1998 FIFA World Cup and 2000 UEFA European Championships. After retiring in 2011, Vieira spent time as Head of Manchester City’s Elite Development Squad before being named head coach of New York City FC ahead of the 2016 MLS season.

Nathalia Holt: "Rise of the Rocket Girls" | Talks at Google


source: Talks at Google     2016年5月20日
Nathalia Holt visited Google's office in Cambridge, MA to discuss her book "Rise of the Rocket Girls: The Women Who Propelled Us, from Missiles to the Moon to Mars".
In the 1940s and 50s, when the new Jet Propulsion Laboratory needed quick-thinking mathematicians to calculate velocities and plot trajectories, they recruited an elite group of young women who, with only pencil, paper, and mathematical prowess, transformed rocket design, helped bring about the first American satellites, and made the exploration of the solar system possible. The book (based on extensive research and interviews with all the living members of the team) tells the stories of these women--known as "human computers"--who broke the boundaries of both gender and science.
Nathalia Holt, Ph.D., is a science writer. Her first book was "Cured: The People who Defeated HIV". Her work has appeared in numerous publications including The New York Times, The Los Angeles Times, The Atlantic, Slate, Popular Science, and Time.
