A Testament of Devotion
Since its first publication in 1941, A Testament of Devotion, by the renowned Quaker teacher Thomas Kelly, has been universally embraced as a truly enduring spiritual classic. Plainspoken and deeply inspirational, it gathers together five compelling essays that urge us to center our lives on God's presence, to find quiet and stillness within modern life, and to discover the deeply satisfying and lasting peace of the inner spiritual journey. As relevant today as it was a half-century ago, A Testament of Devotion is the ideal companion to that highest of all human arts-the lifelong conversation between God and his creatures. I have in mind something deeper than the simplification of our external programs, our absurdly crowded calendars of appointments through which so many pantingly and frantically gasp. These do become simplified in holy obedience, and the poise and peace we have been missing can really be found. But there is a deeper, an internal simplification of the whole of one's personality, stilled, tranquil, in childlike trust listening ever to Eternity's whisper, walking with a smile into the dark."
Memorial Tributes
This is the 11th Volume in the series Memorial Tributes compiled by the National Academy of Engineering as a personal remembrance of the lives and outstanding achievements of its members and foreign associates. These volumes are intended to stand as an enduring record of the many contributions of engineers and engineering to the benefit of humankind. In most cases, the authors of the tributes are contemporaries or colleagues who had personal knowledge of the interests and the engineering accomplishments of the deceased. Through its members and foreign associates, the Academy carries out the responsibilities for which it was established in 1964. Under the charter of the National Academy of Sc...
Too Soon, Too Late
On a winter's night in July 2012, Kathy and Ralph Kelly received a phone call no parent should ever have to answer. It was the Emergency department of a Sydney hospital, telling them that their eldest son Thomas had been in an altercation and that they were to come at once. Thomas had been coward punched by a total stranger within two minutes of getting out of a taxi in Kings Cross, on his way to a private 18th birthday party of a friend. Two days after that first phone call Kathy and Ralph were told that their son had suffered catastrophic head injuries resulting in brain death. They were advised that there was no other option but to switch off his life support. He was 18 years old. In the ...
Design by the Book
Today, China's classical antiquity is often studied through recovered artifacts, but before this practice became widespread, scholars instead reconstructed the distant past through classical texts and transmitted illustrations. Among the most important illustrated commentaries was the Sanli tu, or Illustrations to the Ritual Classics, whose origins are said to date back to the great commentator Zheng Xuan. Design by the Book, which accompanies an exhibition at Bard Graduate Center Gallery, discusses the history and cultural significance of the Sanli tu in medieval China. The Sanli tu survives in a version produced around 960 by Nie Chongyi, a professor at the court of the Later Zhou (951-960...
Moon Lander
Chief engineer Thomas J. Kelly gives a firsthand account of designing, building, testing, and flying the Apollo lunar module. It was, he writes, “an aerospace engineer’s dream job of the century.” Kelly’s account begins with the imaginative process of sketching solutions to a host of technical challenges with an emphasis on safety, reliability, and maintainability. He catalogs numerous test failures, including propulsion-system leaks, ascent-engine instability, stress corrosion of the aluminum alloy parts, and battery problems, as well as their fixes under the ever-present constraints of budget and schedule. He also recaptures the exhilaration of hearing Apollo 11’s Neil Armstrong report that “The Eagle has landed,” and the pride of having inadvertently provided a vital “lifeboat” for the crew of the disabled Apollo 13.
Capturing Music
An accessible history of how musicians learned to record music discusses the work of five centuries of religious scholars while demonstrating how people developed methods for measuring rhythm, melody and precise pitch, leading to the technological systems of notation in today's world.
