Data sonification |
|
Over the past several years, Yager and Margaret Schedel—an associate professor in the Department of Music at Stony Brook University (SBU), where she is also the co-director of the computer music program and an affiliate faculty member at the Institute for Advanced Computational Science—have been combining their expertise to convert x-ray scattering data of nanomaterial structures into sound. To capture these data, Yager uses the Complex Materials Scattering and Soft Matter Interfaces beamlines at the National Synchrotron Light Source II (NSLS-II), another DOE Office of Science User Facility at Brookhaven Lab. These two beamlines are partner instruments jointly operated by the CFN and NSLS-II. |
“I knew that Kevin shoots x-rays at nanoparticles to understand their structure but spends most of his day programming computers,” said Schedel. “One day, I asked him how it all works. He said that x-rays bounce off the atoms in a sample and are recorded by a detector. From that scattering pattern, he can compute the structure of the material with the fast Fourier transform (FFT) algorithm. He started explaining what FFT is, but I stopped him because it is the same algorithm that I use all the time in my computer music work.”
