This crystal doubles images, meaning that if you look through it that anything on the other side whether that be text, a person, or a photo of a volcano will appear to be doubled. But, why does this unusual optical property occur when utilizing a crystal of calcite? The answer is a fascinating phenomenon known as birefringence, which this video will explain through the expertise and analysis of a geologist.

This is the about-page of which text continues past the posted image on the left side:

And as a further aside, the image was made with an F-Droid app that is new to me but popped up 3 months ago apparently and has a lot of great features for stitching images and creating content:

Forever Chemicals' Toxic Cousin: MCCPs Detected in U.S. Air for First Time (cires.colorado.edu)

In a surprising twist during an air quality study in Oklahoma, researchers detected MCCPs an industrial pollutant never before measured in the Western Hemisphere's atmosphere. The team suspects these toxic compounds are entering the air through biosolid fertilizers derived from sewage sludge. While these pollutants are not yet regulated like their SCCP cousins, their similarity to dangerous "forever chemicals" and unexpected presence raise red flags about how chemical substitutions and waste disposal may be silently contaminating rural air.
