The quest for understanding the Earth’s geologic past has puzzled scientists for decades, slowly advancing based on the shreds of evidence left behind. There are clues everywhere – from fossils and remnant minerals to pollen spores of extinct plants, our planet's history can be preserved the most unlikely of places. In this episode hosts Rhys Paterson and Yousuf Hasan talk to Stephen Pilar, a grad student in the Earth Science department discussing a fairly new area of research. By studying microscopic bubbles within rocks and minerals using nuclear magnetic resonance spectroscopy (NMR), he is working on developing new ways to uncover valuable information about Earth’s ancient geology and add another piece to puzzle we call home.To find out more from Stephen, follow him on Twitter @stephenpilar or email him at [email protected]
