Vortices in beams of light and vortex coronagraphy video!
I while ago, I shared slides from a talk I gave at the Charlotte Amateur Astronomy Club on “Vortices in beams of light and vortex coronagraphy.” Now that I, like everyone else, am more or less homebound, I thought I … Continue reading

Visualizing the geometric phase of light!
Another post inspired by my book on Falling Felines and Fundamental Physics! I talk about geometric phases in the book in the context of falling cats, but here I focus on the polarization of light. I regularly argue that most … Continue reading
Vortices in beams of light and vortex coronagraphy
This past Friday, I was invited to give a talk at the monthly meeting of the Charlotte Amateur Astronomers Club, a lovely organization that has been around since 1954. As a theoretical physicist, I am not that well-versed on astronomy … Continue reading

Dr. SkySkull in Amsterdam: Optics in the Rijksmuseum
The lower level of the Rijksmuseum, an area relatively few time-strapped visitors manage to visit, is reserved for more practical forms of art: musical instruments, ceramics, ship figureheads, weapons, and the like. I explored this whole area on my recent … Continue reading

Optics basics: reflection
It’s been some 5 years since I wrote my last “Optics basics” post! The goal of that series of posts was to introduce some of the most fundamental concepts in optics in a non-technical way, in part so I wouldn’t … Continue reading
