To see color, the human visual system combines the responses of three types of cone cells in the retina - a process that discards a significant amount of spectral information. We present an approach that can enhance human color vision by breaking the inherent redundancy in binocular vision, providing different spectral content to each eye. Using a psychophysical color model and thin-film optimization, we designed a wearable passive multispectral device that uses two distinct transmission filters, one for each eye, to enhance the user's ability to perceive spectral information. We fabricated and tested a design that "splits" the response of the short-wavelength cone of individuals with typical trichromatic vision, effectively simulating the presence of four distinct cone types between the two eyes ("tetrachromacy"). Users of this device were able to differentiate metamers (distinct spectra that resolve to the same perceived color in typical observers) without apparent adverse effects to vision. The increase in the number of effective cones from the typical three reduces the number of possible metamers that can be encountered, enhancing the ability to discriminate objects based on their emission, reflection, or transmission spectra. This technique represents a significant enhancement of the spectral perception of typical humans, and may have applications ranging from camouflage detection and anti-counterfeiting to art and data visualization.
Her application letter to The New Yorker - they didn't even bother to reply
March 15, 1933
I suppose you’d be more interested in even a sleight-o’-hand trick than you’d be in an application for a position with your magazine, but as usual you can’t have the thing you want most.
I am 23 years old, six weeks on the loose in N.Y. However, I was a New Yorker for a whole year in 1930–31 while attending advertising classes in Columbia’s School of Business. Actually I am a southerner, from Mississippi, the nation’s most backward state. Ramifications include Walter H. Page, who, unluckily for me, is no longer connected with Doubleday-Page, which is no longer Doubleday-Page, even. I have a B.A.(’29) from the University of Wisconsin, where I majored in English without a care in the world. For the last eighteen months I was languishing in my own office in a radio station in Jackson, Miss., writing continuities, dramas, mule feed advertisements, santa claus talks, and life insurance playlets; now I have given that up.
As to what I might do for you — I have seen an untoward amount of picture galleries and 15¢ movies lately, and could review them with my old prosperous detachment, I think; in fact, I recently coined a general word for Matisse’s pictures after seeing his latest at the Marie Harriman: concubineapple. That shows you how my mind works — quick, and away from the point. I read simply voraciously, and can drum up an opinion afterwards.
Since I have bought an India print, and a large number of phonograph records from a Mr. Nussbaum who picks them up, and a Cezanne Bathers one inch long (that shows you I read e. e. cummings I hope), I am anxious to have an apartment, not to mention a small portable phonograph. How I would like to work for you! A little paragraph each morning — a little paragraph each night, if you can’t hire me from daylight to dark, although I would work like a slave. I can also draw like Mr. Thurber, in case he goes off the deep end. I have studied flower painting.
There is no telling where I may apply, if you turn me down; I realize this will not phase you, but consider my other alternative: the U of N.C. offers for $12.00 to let me dance in Vachel Lindsay’s Congo. I congo on. I rest my case, repeating that I am a hard worker.
Behavior of self-propelled acetone droplets in a Leidenfrost state on liquid substrates

It is demonstrated that non-coalescent droplets of acetone can be formed on liquid substrates. The fluid flows around and in an acetone droplet hovering on water are recorded to shed light on the mechanisms which might lead to non-coalescence. For sufficiently low impact velocities, droplets undergo a damped oscillation on the surface of the liquid substrate but at higher velocities clean bounce-off occurs. Comparisons of experimentally observed static configurations of floating droplets to predictions from a theoretical model for a small non-wetting rigid sphere resting on a liquid substrate are made and a tentative strategy for determining the thickness of the vapor layer under a small droplet on a liquid is proposed. This strategy is based on the notion of effective surface tension. The droplets show self-propulsion in straight line trajectories in a manner which can be ascribed to a Marangoni effect. Surprisingly, self-propelled droplets can become immersed beneath the undisturbed water surface. This phenomenon is reasoned to be drag-inducing and might provide a basis for refining observations in previous work.
Amazon recently launched a companion storytelling experience to complement their series The Man in the High Castle.
