German-born optometrist George Mayerle developed a rather comprehensive and inclusive eye chart whilst practising in San Francisco that reflected the diversity of his adopted home.
The radiant dials above test for astigmatism and the bars at the bottom can be used to reveal colour-blindness. Different scripts are represented as well as pictorial characters and geometric symbols for the pre-literate and is nearly contemporaneous with the Snellen table that we’re probably best acquainted with.

worshipful company
Despite not entering into common-parlance unlike some of the other phrases he turned like Boston Brahmin or anesthesia, the term epeolatry coined by poet, physician and polymath Oliver Wendell Holmes, Senior (Junior was the US Supreme Court justice) that means the adoration of words deserves a champion. Holmes’ Breakfast-Table series of essays, where the concept was first elaborated, were the foundational dialogues of The Atlantic Monthly—a publication that Holmes named and helped establish.

a real trooper
Our thanks to Things Magazine for introducing us to the concept of an eggcorn, similar to an oronym—that is a word or phrase that can be substituted for another, as in “We all scream for ice-cream!” or a mondegreen, a misheard lyric (the ballad goes “They have slain the Earl O’Moray, and laid him on the green”) which was coined in 2003 to describe the idiosyncratic substitution of one word for another plausible, possibly more sensical one.
Linguists were discussing the case of an individual convinced that the nut of oak tree was called an eggcorn and it was difficult to persuade her otherwise. Alzheimer’s disease might be fairly logically characterised as old-timers’, especially when the term was new or having another think (as in the need to re-think one’s stance) coming makes less sense than having another thing coming, bolstered by song, or chomping versus champing at the bit. What other folk etymologies can you think of? Photochop? Are you the veteran member of your troupe, reliable and uncomplaining? I wonder what other convoluted constructions might be attributed to a similar transformation and drive to re-couch a phrase in terms that come across as more logical to contemporaries.

Researcher Kohske Takahashi presents a new sort of optical illusion that he has named “curvature blindness” which is manifested as the identical sets of lines pass over the grey field and appear to retain and take on alternating properties of a wave and a more angular trough. No one is certain about the mechanism behind this cognitive illusion but Takahashi suspects that registering sharper corners might be the default, Gestalt mode of human visual perception and what we retreat to when faced with a confusing arrangement. Same-otherwise, this visual trickery and related stunts could also be grounded in the self-deception that the human brain creates for our benefit that reduces the granularity of the senses and make things seem smooth and continuous, despite gaps and delays.
