Protecting Sight #161: Making sense of a visible quantum object. Nuclear pieces & arcus senilis. Chorioretinal lesions post HZV infection. Atomic habits vs. tiny habits.

Welcome to my daily learning journal. My daily goal is to watch one Ted Talk and one cataract surgery. I also plan to read one journal article and read/listen to a book chapter, short story or significant work.

Here’s today’s list:

1. Ted Talk – Aaron O’Connell: Making sense of a visible quantum object. “Physicists are used to the idea that subatomic particles behave according to the bizarre rules of quantum mechanics, completely different to human-scale objects. In a breakthrough experiment, Aaron O’Connell has blurred that distinction by creating an object that is visible to the unaided eye, but provably in two places at the same time. In this talk he suggests an intriguing way of thinking about the result.” (

Very cool.

2A. Cataract Surgery – Uday Devgan MD – Cataract Quiz: Where is the hidden piece? Dr. Devgan writes, “Time for another cataract quiz — look carefully at the photo above. Where is the nuclear fragment hiding? And how did it end up behind the IOL? This is a tough case because the patient is 96 years old and he waited until his cataract became very dense, his ocular structures became weak, and his corneal endothelial cell count dropped.”

2B. Dr. Telegin (Russia) – Dr. Telegin is a brilliant cataract surgeon who posts surgeries on Instagram.

3. Long CP, Bakhoum MF, Freeman WR. Depigmented Chorioretinal Lesions Following Varicella-Zoster Virus InfectionJAMA Ophthalmol. 2020;138(11):e201652. doi:10.1001/jamaophthalmol.2020.1652

4. The Knowledge Project (Shane Parrish) – “Episode 86: BJ Fogg: Create Lasting Change — Behavior scientist and author of Tiny Habits, BJ Fogg, discusses improving decision making, motivation trends, the role of emotion in sense of self and so much more.”

This blog was influenced by James Clear’s Atomic Habits, which shares similar concepts to BJ Fogg’s Tiny Habits.
