Quartz crystal— a technology that changed the tide of World War II

Some of the defining leaps in technology in the twentieth century occurred during the Second World War, from radar to nuclear energy. Often left out of historical discussions are quartz crystals, which proved to be just as pivotal to the Allied victory— and to post-war development— as other technologies. Quartz crystals provided the U.S. military, for the first time, with reliable communication on the front lines, and then went on to become the core of some of the most basic devices of the post-war era, from watches, clocks, and color televisions, to cell phones and computers.

In Crystal Clear, Richard Thompson relates the story of the quartz crystal in World War II, from its early days as a curiosity for amateur radio enthusiasts, to its use by the United States Armed Forces. It follows the intrepid group of scientists and engineers from the Office of the Chief Signal Officer of the U.S. Army as they raced to create an effective quartz crystal unit. They had to find a reliable supply of radio-quality quartz; devise methods to reach, mine, and transport the quartz; find a way to manufacture quartz crystal oscillators rapidly; and then solve the puzzling "aging problem" that plagued the early units. Ultimately, the development of quartz oscillators became the second largest scientific undertaking in World War II after the Manhattan Project.

Bringing to light a little-known aspect of World War II, Crystal Clear offers a glimpse inside one of the most significant efforts in the annals of engineering.


Jacqueline Du Pre by Elizabeth Wilson, ISBN 155970490X

She was beautiful. She was a musical genius. She was married to another prodigious musician, the conductor and pianist Daniel Barenboim. Their fairy-tale marriage turned them into a royal musical couple. In this definitive biography, Elizabeth Wilson, herself a cellist who knew Jacqueline du Pre in her playing days, charts du Pre's meteoric career from her early identification with the sound of the cello to the achievement of her stardom by her early twenties, when she became a legend virtually overnight. For over a decade Jacqueline du Pre performed the cello repertory with all the best symphonic orchestras to standing-room-only houses around the world, and during those years she also recorded the entire cello literature. At the age of twenty-seven, however, Jackie was felled at the height of her career by multiple sclerosis. She died in 1987, leaving behind a rich and extraordinary musical legacy, and renowned as one of the best-loved musicians of the century. The author details Jackie's...

In addition to providing a descriptive analytical overview, the book also chronicles the work's initial composition and subsequent revisions. It concludes with a discussion of the composer's own prescribed tempos, along with a comparison of several different recordings. Sibelius, Symphony No. 5 by James A. Hepokoski, ISBN 0521409586

Schubert: Die Winterreise (Widescreen)

Acclaimed Czech Filmmaker Petr Weigl directs this deeply affecting dramatization of Franz Schubert's masterwork "Die Winterreise" ("The Winter Journey") with a heart-rending vocal interpretation by mezzo soprano Brigitte Fassbaender. "Die Winterreise" is not an opera but a cycle of songs drawn from a series of poems and has been called Schubert's greatest legacy in a remarkably prolific career.
Completed on Schubert's deathbed, the songs tell a number of emotionally charged, interwoven stories liking the characters, who travel together by carriage on a bleak winter's day in the early 1800s. Weigl created his film with an eye toward conceptual expression of theme and mood ather than merely illustrating the events of the stories.
At times the visual imagery in the film literally follows the words and music.
At other times, the images are more abstract, serving as a counterpoint or even flow independently of the musical work.
The music, as well as the visuals,... Schubert: Die Winterreise (Widescreen)

Brahms: Symphony No. 1 by David Brodbeck, ISBN 0521479592

Brahms's First Symphony has been hailed as Beethoven's Tenth. Its controversial status and relationship in the Beethovenian tradition is considered alongside other important issues in the early reception history of this key work in the symphonic repertory. David Brodbeck begins with an account of the lengthy genesis and complicated background to the writing of the symphony, before providing a thorough critical reading of the work, movement by movement. In particular, Professor Brodbeck reveals a dense web of extra-compositional allusions--references in the music to works by J. S. Bach, Beethoven, Schubert, and Robert Schumann--in which, the author argues, much meaning resides. Brahms: Symphony No. 1 by David Brodbeck, ISBN 0521479592
