Despite its simple molecular structure, β-alanine can make crystals that look breathtaking under the right conditions. After drying an ethanol-water solution of β-alanine on a microscope slide, Gregory Suryn, a lecturer at Gettysburg College, took this photo as he developed group activities to do with his students. By using a macro lens for his camera and two circular polarizers, Suryn was able to zoom in on this area that’s just a few centimeters wide, and he observed this spectrum of colors, which results from the way the crystals are aligned with and interact with polarized light.
