Goodbye Aberration: Physicist Solves 2,000-Year-Old Optical Problem (PetaPixel)

Héctor A. Chaparro-Romo, a doctoral student at the National Autonomous University of Mexico (UNAM), who had been trying to solve this problem for 3 years, invited Rafael G. González-Acuña, a doctoral student from Tec de Monterrey, to help him solve the problem.

After months of working on solving the problem, Rafael González recalls, “I remember one morning I was making myself a slice of bread with Nutella when suddenly, I said out loud: Mothers! It is there!”

From my perspective, this is the critical part of the article:

Afterwards, the duo ran a simulation and calculated the efficacy with 500 rays, and the resulting average satisfaction for all examples was 99.9999999999%. Which, of course, is great news for gear reviewers on YouTube, as they will still be able to argue about the 0.0000000001% of sharpness difference among lens brands.
