Protecting Sight #57: The mathematician who cracked Wall Street. Huck Finn & Tom Sawyer reunite!

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 – Jim Simons – The mathematician who cracked Wall Street. “Jim Simons was a mathematician and cryptographer who realized: the complex math he used to break codes could help explain patterns in the world of finance. Billions later, he’s working to support the next generation of math teachers and scholars. TED’s Chris Anderson sits down with Simons to talk about his extraordinary life in numbers.” (

Legendary hedge fund pioneer. Nice discussion. Filled with life lessons. 23 minutes.

2A. Cataract Surgery – Uday Devgan MD Which resident will win this contest? Great examples. Love Uday’s pearl to strive for 1% improvement per week. (See also James Clear’s Atomic Habits.)

2B. Cataract Surgery – Richard Mackool MD – Episode 9: The Deformed Cornea. “Case Description: Here is a very unusual case! This 62 year old man has a cataract and severe keratoconus with a refraction of -20.00 D, -11.00 D of cylinder, and K readings in the 80s!” Awesome case.

3A. Journal article – Comparing the Management of Eye Injuries by Coalition Military Surgeons during the Iraq and Afghanistan Conflicts. John Breeze, Richard J. Blanch, Robb Mazzoli, Joseph DuBose, Douglas M. Bowley, David B. Powers. Ophthalmology April 2020. p458–466

  1. Great post!

    I have fond memories of doing a live surgery event with Dick Mackool at the Singapore National Eye Center. He is such a good teacher and I learned so much. The two of us proudly represented the US at that large international meeting
