Guest Video: The Diatomist


I came across diatoms and radiolarians–tiny little sea creatures–while looking up the history of climate change over the span of geologic time that cats and cat-like creatures evolved.

I’d never heard of either one before but noticed that the images in various scientific papers were beautiful. What a surprise to learn that Victorians knew this, too, and actually made microscopic art of diatoms!

And someone is still doing it today.

Guest Video: Microphotographs of Gemstones

Microphotgraphy using polarized light yields beautiful art.  It also is very helpful in learning more about a gem.

 

 

Tomorrow we’ll check out a couple other ways that microscopy reveals information about places we can’t reach: the deep Earth and the past.
