Harvard researcher Karen King today unveiled an ancient papyrus fragment with the phrase, “Jesus said to them, ‘My wife.’” The text also mentions “Mary,” arguably a reference to Mary Magdalene. The announcement at a religious studies conference in Rome is sure to send shock waves through the Christian world. The Smithsonian Channel will premiere a special documentary about the discovery on September 30 at 8 p.m. ET. And Smithsonian magazine reporter Ariel Sabar has been covering the story behind the scenes for weeks, tracing King’s steps from when a suspicious e-mail hit her in-box to the nerve-racking moment when she thought the entire presentation would fall apart.

There were many attempts to explore Mars using Space missions. As of July 2007 the success rate was 47%. Interestingly, Soviets were the first to attempt it, but Americans were the most successful ones. In coming centuries, the exploration will look different with China and India coming into play. The following infographics tells the whole story:

Of Hyperion we are told that he was the first to understand, by diligent attention and observation, the movement of both the sun and the moon and the other stars, and the seasons as well, in that they are caused by these bodies, and to make these facts known to others; and that for this reason he was called the father of these bodies, since he had begotten, so to speak, the speculation about them and their nature.—Diodorus Siculus (5.67.1)

The Topic:
On the Shoulders of Eastern Giants: The Forgotten Contributions of Medieval Physicists
Event Date: Thursday, October 20, 2011 at 4:00 PM BST
Summary:
We learn at school that Newton is the father of modern optics, Copernicus heralded the birth of astronomy, and Snell deduced the law of refraction. But what debt do these men owe to the physicists and astronomers of the medieval Islamic Empire? What about Ibn al-Haytham, the greatest physicist in the 2000-year span between Archimedes and Newton, whose Book of Optics was just as influential as Newton’s seven centuries later? Or Ibn Sahl, who came up with the correct law of refraction many centuries before Snell? What of the astronomers al-Tusi and Ibn al-Shatir, without whom Copernicus would not have been able to formulate his heliocentric model of the solar system? In this lecture, Jim Al-Khalili recounts the stories of these characters and more from his new book Pathfinders: The Golden Age of Arabic Science.
The webinar will run for approximately 45 minutes with time for a Q&A at the end.
Speaker: Jim Al-Khalili, Professor of Physics and Professor of the Public Engagement in Science at the University of Surrey, UK.
Jim Al-Khalili is a physicist, author and broadcaster. As well as his work on radio and television, he has written a number of popular-science books, the most recent of which is Pathfinders: The Golden Age of Arabic Science. His awards include the Royal Society Faraday Prize (2008), the IOP Kelvin Medal (2011), an OBE in 2008 and a Bafta nomination.
