On February 17, 1864, in the waning years of the Civil War, the Confederate submarine H.L. Hunley pressed a black powder explosive against the side of the Union ship USS Housatonic and sank it, becoming the first submarine ever to be successful in combat. Even though the submarine was raised in the year 2000, efforts to conserve her only deepened the mystery of why she sank, as the remains of the crew were all found seated peacefully at their battle stations with no signs of trauma or attempts to escape the doomed vessel. Dr. Rachel Lance, an expert in biomedical engineering from Duke University, will present an illustrated lecture on her research, and findings as to the fate of the Hunley and her crew.

Michael Krasny visits Google’s San Francisco office to present his book “Spiritual Envy: An Agnostic’s Quest”. This event took place on January 26, 2011, as part of the Authors@Google series.
Books by agnostics about their agnosticism (unlike the prolific atheists) are anything but a dime a dozen. In fact, Krasny’s latest is one of only a dozen or so published this century. Krasny may be a university professor, but he doesn’t address his questions as an academic. He explores agnosticism the way he explores topics on his daily NPR show—in a thoughtful, informed, and almost conversational tone. The main difference is this isnt just any issue; it’s Krasny’s own story. The author’s honesty begins with the book’s title. He obviously envies the feelings of peace and comfort that people of faith experience. Keeping him from it, though, are innumerable questions. The book presents these ruminations with only hints to the answers. The questions involve issues like the Ten Commandments, God’s existence, evil, and tolerance. Along the way, Krasny brings many people into the conversation—fellow agnostics like Thomas Huxley, atheists like Richard Dawkins, and even biblical characters like Job. The author’s nondogmatic stance will please virtually all readers.
