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.

Lunar Eclipse 2022

This photograph is a time-lapse of the total lunar eclipse on May 15, 2022, taken in the Paradise Valley of the Yellowstone River in southwestern Montana just north of Yellowstone National Park. The moon rises in near-totality in the East, ascending like a firework above the Absaroka Range.

Antiqua Vesicae

This photograph depicts the union of sun and earth in life through photosynthesis. Facilitated by solar energy, algae build silica frustules which eventually sink to the seafloor, becoming diatomaceous earth, the chalky substance which traces out the vesica piscis shape found in this image.

Now available for purchase.

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 learned about how electrochemistry works, the definitions have evolved somewhat. The following is a brief summary of their etymology and their meaning as it stands today in electrochemical circuits. In the course of my own study of electrochemistry, I thought other students may find this information helpful in keeping everything straight.

Cooking chicken with a powerful slap

A question has been going around the social networks: If kinetic energy is converted to thermal energy upon impact, how hard to you need to slap a chicken to cook it? One response suggested raising the chicken’s temperature to 400 °F, which is far too hot, and it used an “average slap energy” that was not explained. Here then, is my analysis.

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 a quake.

Awareness cannot of itself crash waves;
By heat and light, the box became a grave.
