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 – James Earle: Da Vinci’s Vitruvian Man of math. “What’s so special about Leonardo da Vinci’s Vitruvian Man? With arms outstretched, the man fills the irreconcilable spaces of a circle and a square — symbolizing the Renaissance-era belief in the mutable nature of humankind. James Earle explains the geometric, religious and philosophical significance of this deceptively simple drawing. [Directed by Franz Palomares, narrated by James Earle].” (ted.com)
Wonderful insights in this Ted-Ed Talk.
2. Uday Devgan MD – Drill and Chop Technique. Dr. Devgan writes in part, “This video is from Dr. Anant Vir Jain MS from Ghaziabad, India and he shows a technique of first drilling a hole into the sub-incisional nucleus, then rotating the nucleus 180 degrees, and finally performing the chop with the instrument placed inside this drill hole.” Excellent technique and narration.
3. Journal – Cohen DA, Chen JJ, Leavitt JA. A 2-Year History of Diplopia, Optic Disc Edema, and Amaurosis. JAMA Ophthalmol. 2019;137(1):103–104. doi:10.1001/jamaophthalmol.2018.2604
4. Book Chapter – Leonardo da Vinci by Walter Isaacson. Chapter 7, “Personal Life” Another masterful chapter in which Isaacson explores Leonardo’s relationship to Salai. Love the Allegorical drawing of Pleasure and Pain. (See also IndraMusings blog here).
