Volcanic Ash & Guitar Physics
On this week’s show, we discuss the possible human health risks caused by the Icelandic E15 Volcano with Dr. Tim Jones, Senior Lecturer at the Cardiff University School of Earth & Social Sciences. Our STEM Ambassador of the Week is David Dodd from Scottish Power. We also welcome guitar physicist Dr. Mark Lewney into the studio. He explains why the rock guitar has such a distinctive sound and how the whole world could be made of music! Finally, this week’s Subject of Science is Chinese engineer and pioneer of pre-stressed concrete, Tung-Yen Lin.
