Episode notes
Capturing Snowflakes In An SEM
- Michael Benson built a cryopod workflow to transport snowflakes into a scanning electron microscope without melting them.
- He used liquid nitrogen and had only about three minutes to capture high-quality SEM images before sublimation ruined the sample.
Microscopes As A Different Kind Of Space
- Michael Benson frames his SEM work as exploring 'space' at a different scale, connecting cosmic and microscopic imaging.
- He wanted to examine natural design at sub-millimeter scales, smaller than a grain of salt.
SEM Reveals Surface Worlds
- A scanning electron microscope uses electrons instead of photons, enabling much higher magnifications and surface detail than optical microscopes.
- Benson learned SEM operation at the Canadian Museum of Nature and treats the outputs as micography in the history of photography.
