RIT Microscopy class dedicates its spring semester to Michael Davidson

I first met Michael Davidson in 1989 when I was a judge at the Nikon Small World competition. I met him a second and last time in 2009, when I was again a judge of the Nikon Small World competition. I knew immediately, he might be the most passionate microscopist that I had ever met. He was truly in a league unto himself in productivity. He began the Molecular Expressions website  June 19, 1998. What a tremendous resource. As time passed, the website grew and grew and grew. Companies such as Nikon, Zeiss, Leica, and Olympus supported his work and enabled Michael to continue to share his knowledge, and build his lab and the Molecular Expressions website. He did so many great things.


While we were not close friends, we did collaborate a few times. Michael wrote a chapter for the Focal Encyclopedia of Photography -fourth edition.  I was the editor-in-chief of that book. His contribution to the book and so many other things were extraordinay.

As a personal tribute, I am dedicating this semester’s microscopy work to Michael and what he meant to this field

A virtual class notebook

Welcome to the Class Notes Blog. I created this Blog to share work from me or my students about things we are learning. At the time, I wanted to start the Blog ( January 2016) to provide 22 students studying microscopy an opportunity to explore the subject of Blogging and share their new knowledge and skills. I asked each student to publish three entries to this Blog by mid March when my role in the class was finished. Their first post was due February 5, 2016. The post featured a science image or maker that they found particularly interesting. I asked them to gain permission from the images’ creator before they could use it on the site.  I hope you enjoy reading this experiment sharing my classroom activities.

This photomicrograph features Merck® Foradil asthma medicine. It was photographed using a polarized light microscope. The solid pill of the medicine was dissolved in water and then plated onto microscopy slides to allow the formation of crystals. The colors shared above demonstrate the presence of birefringent properties of the chemicals contained in the medicine. Photograph: Professor Michael Peres.
