Penrose Tessellation Cookie Cutters

Over the holiday break, I took a little time for a side quest that engaged my creativity while involving mathematics, 3D modeling, and baking. I designed a pattern based on Penrose tiles and made it into cookies.

The Etymology and Meaning of Anode and Cathode

The terms “anode” and “cathode” were first published by Michael Faraday, F.R.S. in 1834. A delightful (and highly recommended) historical account of how these words were conceived by Faraday and his associates can be found in Faraday Consults the Scholars: The Origins of the Terms of Electrochemistry by Sydney Ross [1]. As scientists have learnedContinue reading “The Etymology and Meaning of Anode and Cathode”

Schrödinger’s Cat, a sonnet

Should quantum physics e’er be standardized, when taken in a thought experiment, its terms of meaning judged and analyzed, absurdity prevails, not merriment. A cat both dead and living cannot be. That was the point old Erwin tried to make. To measure is to interfere, you see, some photon must be thrown to cause aContinue reading “Schrödinger’s Cat, a sonnet”

Conference Paper in TechConnect Briefs

I’m a co-author of a newly published conference paper entitled “Diatom Frustules as Substrates for Photocatalysts” in TechConnect Briefs 2018 vol. 2: Materials for Energy, Efficiency and Sustainability.

Photo published in Astrobiology Magazine

One of my photographs was featured in this April 12, 2018 article in NASA’s Astrobiology Magazine: “Are viruses the new frontier for astrobiology?” The photo originally appeared in the Portland State Vanguard, in this short article and interview with accompanying photos and video about the research of Prof. Ken Stedman.

Green chemistry seminar videos

Join the Portland, Oregon section of the American Chemical Society for a couple of wonderful talks on Green Chemistry. First, Dr. David Stuart, Assistant Professor of Chemistry at Portland State University, offers a brief introduction to Green Chemistry and an example from his lab. Next, Dr. Tom Wilson, retired Director of Materials Technology at Nike,Continue reading “Green chemistry seminar videos”

Portland ACS interview

The Portland section of the American Chemical Society interviewed me about my internship at NASA Glenn Research Center in Cleveland, Ohio in summer, 2015, where I worked on lithium-sulfur battery research.
