Three Years in Micrographs

August 11, 2016

For the past three years as a biology student, I spent every Tuesday and/or Thursday in the coldest labs for three hours or so. Some of them pass by more easily than others, but I always love one with some microscopy involved. I started taking photos through the microscope in freshman year out of curiosity and laziness (surprise!) so my teary eyes wouldn’t have to strain so much to sketch these. I thought I’d share the best in my collection so far as I enter my senior year! If any of you are interested in my methods to take these photos, I just used my iPhone with a really steady hand to the eyepiece.

I believe this is the cross section of a frog cilia, but it’s been four years and I probably remembered incorrectly.
