137: Light My Fire

The History of Chemistry

Aerogels, those feather-weight materials, have a century-old history. We begin with Samuel Kistler, the inventor of the first aerogels, and move forward through time with loss of interest in them, then revival of interest in the 1970s. We learn about gradual improvements in their fabrication over time. Then we talk of their fascinating properties, and then their uses.
