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

A TikTok video on anholonomy, Foucault’s pendulum, and falling cats!
I’ve been spending more time making videos lately on TikTok, and I saw a video from a young woman inadvertently demonstrating the concept of anholonomy, which is related to everything from Foucault’s pendulum to light polarization to falling cats! I … Continue reading
