The Duchess of Cambridge has delivered her first public address, giving a brief, confident speech at a children’s hospice in eastern England. The former Kate Middleton spoke clearly and deliberately as she addressed staff and volunteers at East Anglia’s Children’s Hospice in the English port town of Ipswich. She glanced frequently at her notes at first but seemed to make a good impression Monday, drawing chuckles when she said she was sorry that her husband, Prince William, could not join her. He is on military assignment in the Falkland Islands. … Albert Einstein’s complete archives — from personal correspondence with half a dozen lovers to notebooks scribbled with his groundbreaking scientific research — are going online for the first time. The Hebrew University of Jerusalem, which owns the German Jewish physicist’s papers, is pulling never-before seen items from its climate-controlled safe, photographing them in high resolution and posting them on the Internet. Only 900 manuscript images, and an incomplete catalog listing just half of the archive’s contents, had been posted online since 2003. Now, with a grant from the Polonsky Foundation UK, which previously helped digitize Isaac Newton’s papers, all 80,000 items from the Einstein collection have been cataloged and enhanced with cross referencing technology. … A judge declared a mistrial Monday in Nicollette Sheridan’s wrongful termination trial after the jury deadlocked, leaving an unresolved finale to a two-week trial that focused behind-the-scenes of TV’s “Desperate Housewives.” Superior Court Judge Elizabeth Allen White excused the panel after it deadlocked 8-4 in favor of Sheridan’s claim. Sheridan had been seeking roughly $6 million from her former employers. She claimed her role as Edie Britt was eliminated because she complained that series creator Marc Cherry struck her in the head during a September 2008 on-set dispute.
