Infinite singularities in an optical beam???
Working on the second edition of my Singular Optics textbook and thought I would blog about some of the fun developments in the field that I’ve come across while doing the book research! Light has wave properties, and as a … Continue reading
The most beautiful wrong equation in history (1841)
One of the topics of the history of science that has continued to fascinate me is the discovery of the principle of conservation of energy. As I discussed in my three-part series “Booms, Blood, and Beer” (part 1, part 2, … Continue reading
What is a Carnot engine?
I’ve recently been trying to “relearn” thermodynamics, a subject that I haven’t really looked at, or had to look at, for years. I put “relearn” in quotes because I never really learned it well in the first place! One of … Continue reading

Maxwell invents a demon, people get angry (1879)
Some time ago, I was browsing 150 year old popular science magazines as one does and I found an amusing editorial from 1879 in The Popular Science Monthly titled “Explanations that do not explain.” The unsigned editorial discussed a recent … Continue reading
What is a quantum eraser?
My training and background as a physicist is largely in the field of so-called classical optics: the study of the wave properties of light. Lately, however, I’ve been planning more investigations into quantum optics — the study of the quantum … Continue reading

A retrospective on my first published scientific paper
I’ve had a pretty long career in physics, optics in particular, at this point: I have published over 150 peer-reviewed papers and have written 5 books. Looking back to the start of my journey in science, I don’t think I … Continue reading
An introduction to quantum cryptography
I’ve been brushing up on my quantum physics and quantum information science lately, and thought it would be good practice for me to give a little introduction to the idea of quantum cryptography, and one of the first strategies proposed … Continue reading
Nicol invents a polarizing prism (1828)
I’ve talked a lot about polarization recently, including the story of how the best polarizing material was discovered on accident and how modern polarizers made from that material really changed science and technology in a major way. Along the way, … Continue reading
Polaroid: the game-changing optical technology (1938)!
Some technology is so pervasive and mundane in modern society that it is hard to comprehend what a seismic shift its introduction caused in civilization. Examples I can think of are refrigerators and air conditioning, but in science an example … Continue reading
