Hedy's Folly by Richard Rhodes

Hedwig Kiesler was a headstrong Austrian girl with visions of becoming a Hollywood star. She was so determined that she dropped out of school to star working at a Berlin film studio, and by 16 she was acting professionally. She eventually achieved Hollywood stardom as Hedy Lamarr.

Lamarr had another, lesser known life, as an inventor. She, along with avant-garde composer George Antheil, invented a technology that makes much of modern communication possible. Richard Rhodes focuses on this part of Lamarr’s life in Hedy’s Folly.

The woman known for her beauty was interested in technology from youth. She enjoyed walking with her father, a banker, who explained how things worked. Her first marriage was to munitions manufacturer Fritz Mandl. Though she was mostly a trophy to be shown off to his friends, she paid close attention as he and the people he entertained discussed weapons and other technology. When she moved to Hollywood, she sat up a little shop in her home and took up inventing as a hobby.

When Lamarr learned of the sinking by U-boats that were intended to carry children from Britain to safer locations in Canada, she put her head to the idea of improved torpedoes to combat the underwater threat. The torpedo would be remote controlled. To avoid attempts to jam the signal, the torpedo receiver and controller transmitter would can radio frequencies rapidly in a synchronized manner.  She enlisted the assistance of Antheil, who had experience trying to control and synchronize multiple player pianos, to work out a practical implementation of the concept.

The idea was received well by the National Inventors Council, apparently even receiving the endorsement of automotive engineer Charles Kettering. The Navy did not think the idea was practical, but it did by the patent that was awarded to the Hollywood pair in 1941. Eventually, the frequency-hopping technology invented by Lamarr was developed by the U.S. military for many communication applications.

Spread spectrum, a somewhat broader category of radio communication of which frequency-hopping was the original type, was unveiled from the military secrecy in 1976 with the publication of a textbook on the subject by Robert C. Dixon. The Federal Communications Commission (FCC) moved fairly quickly to make room in the radio spectrum for applications of spread spectrum. These were mostly junk frequencies that had been set aside for non-communication uses. Because it broadcast on multiple frequencies, spread spectrum is less likely to be disrupted by interference by other transmissions, like a microwave (Lamarr invented frequency hopping to avoid jamming). Another important aspect of the FCC rule was that these frequencies could be used without a license.

This technology is widely used today. Wi-fi, Bluetooth, GPS, and RFID all use spread spectrum communication. It is the basis of the wireless communication between computers that has shaped the way we live, work, and behave in coffeehouses.

Lamarr and Antheil didn’t receive much recognition for their groundbreaking invention until after it started making its way into American households and pockets. In 1997, Lamarr (and posthumously Antheil) received the Electronic Frontier Foundation’s Pioneer Award when she was 82 years old. By then she had retired to a very private life in Florida, where she live until January 2000.

A Wrinkle in Time by Madeleine L’Engle

L’Engle, Madeleine.  A Wrinkle in Time.  1962.  New York: Laurel-Leaf, 1976.

Though I review all the nonfiction books I read, I write about only a little about fiction.  Sometimes a fiction book hits so many areas of interest to me that I want to write about it.  A Wrinkle in Time is one.  It’s a classic, award-winning novel.  It’s a children’s or young adult book, and one is never too old for a good kid’s book.  It’s science fiction.  It’s informed by author Madeleine L’Engle’s Christian faith.

Margaret (Meg) Murphy is an awkward girl who doesn’t fit in.  Her family is unusual, too.  Her father is missing, though Meg stubbornly clings to hope that he will come home.  Her mother is a scientists, caring but somewhat unconventional.  Two of her brothers, twins, are pretty normal, if a little rough, and the third, the youngest, is a genius and most people find him unpleasantly odd.

Meg, her genius baby brother Charles Wallace and Calvin O’Keefe (an older, popular boy who keeps his oddness better wrapped) are pulled into an adventure in space by three creatures, seeming witches, aliens and more.  On another planet, they rescue Meg’s father and almost succumb to the powerful mind that rules the planet.  It is the things Meg dislikes most about herself that allows her to prevail.

A Wrinkle in Time is an adventure.  It is also a parable.  Part of the message is Christian.  The universe is God’s creation for His glory, and good creatures acknowledge and worship Him.  Yet there is evil, and Earth is infected with it.  Love overcomes evil.

It is tempting to see a political message.  On the world Meg visits, Camazotz, a single being rules all, taking responsibility for every decision, instilling uniformity so that everybody has the same things.  It is not hard to see this as a parallel to a communist state, where the government controls and distributes all resources.  It sounds like the nanny state as well, where people are relieved of the responsibilities of caring for themselves and making their own decisions.

It is this last point that I think is important to L’Engle whether or not is has political implications.  We are made to be individuals, unique and special, and we cannot be separated from responsibility for ourselves and our decisions and still have real joy, even if we have everything we seem to need.  When the “aunts” give gifts to the adventurers to prepare them for their trial, they give Meg her faults.  As Christians, we believe that everyone is uniquely made by God.  Our faults, shortcomings, imperfections make us needy of God’s grace, and His grace abounds in us to His glory.

In addition, IT, the mind-lord of Camazotz, is a finite being with finite imagination, thus the uniformity of the planet IT rules.  God is infinite, and His creation has enormous variety, abundance, scope and beauty beyond your imagination.  We can love, serve, and worship one God, we can all be imitators of Christ, and still each be a unique individual.

Before closing, I’d like to mention another Christian sci-fi classic, The Space Trilogy by C. S. Lewis.  There are some parallels between the works.  For instance, both L’Engle and Lewis, in Out of the Silent Planet, depict Earth as darkened and separated from communion with the larger universe because of the influence of human sin and the dominion of Satan.  IT, a big brain, reminds me of the Head from Lewis’ That Hideous Strength.
