And Marilyn Emerson Holtzer, a chemist at the University of Washington who specializes in studying protein folding, is also an internationally recognized weaver, and the winner of several awards for her weaving innovations. Her science and her weaving intersect because, in each, she explores the patterns that she works with in the other field. Another practical application of pure art comes from the Jet Propulsion Laboratory of the National Aeronautics and Space Administration. Milton Halem, who is in charge of analyzing data from the Landsat satellite, has collaborated with the artist Sarah Tweedy, of the Corcoran School of Art in Washington, to determine how to display the important points in the data without losing their nuances. How to make data intelligible calls on the art of design, and it is an art that every scientist needs to master.
Music can also produce insights useful to science and technology.
In 1942, the composer George Antheil and the actress Hedy Lamarr suggested using the melody of a song as a way of sending signals in Morse code. The person receiving the message would already know what song was being used and would constantly retune his receiver to the frequency of the next note in the song to hear the Morsecode version of the next letter in the message. Someone who didn't know which song was being used would have no idea what frequency to listen to. The concept has spawned hundreds of patents and is the basis of many of the secure communications systems now used by the U. S. military. Another important invention with a musical component is the heart pacemaker.
