Protecting Sight #311: The world’s biggest battery looks nothing like a battery. Phaco access, spin, wedge, & palinopsia. A writer’s fear and confidence.

Welcome to my daily learning journal. Here is today’s list:

1. Ted Talk – TED-Ed: The world’s biggest battery looks nothing like a battery. “As of 2020, the world’s biggest lithium-ion battery is hooked up to the Southern California power grid and can provide enough power for about 250,000 homes. But it’s actually not the biggest battery in the world: a pair of lakes are. How can lakes be a battery? Explore how inventors are rethinking what a battery can be, and how these surprising solutions could help us achieve a sustainable future. [Written by Elizabeth Cox and George Zaidan, directed by Lisa LaBracio, narrated by Jack Cutmore-Scott, music by André Aires].” (

Ted-ED talks, often 5 minutes, are fast-paced and filled with insights.

2. Cataract Surgery – Dr. Neto Rosatelli – Phaco Clip #134 – Nasal Access SPIN & WEDGE. Dr. Rosatelli is a master surgeon. The on-screen vignettes enhance the surgical videos.

3. Andrew Lee MD – Palinopsia.

4. William Zinsser, On Writing Well: The Classic Guide to Writing Nonfiction. Chapter 21, “Enjoyment, Fear and Confidence.”

I regret not reading this book in high school.

Happy Tuesday!
